Description

Mixing and reaction device

Technical field

The present invention relates to a mixing and reaction apparatus, and more particularly to a mixing and reaction apparatus which can sufficiently mix a substance to be treated or sufficiently mix a substance to be treated to be sufficiently reacted. Background technique

Microreaction technology is a method and technique for applying the inherent advantages of microstructures to physical or (and) chemical processes, and devices or devices embodying such techniques are referred to as microreactors. A microreactor is a miniaturized physical or (and) chemical reaction system with a unit reaction interface dimension on the order of microns. It is a micro-chemical technology that emerged in the 1990s.

The reaction interface of the microreactor is at least one dimension up to the order of microns, typically tens to hundreds of microns. At this microscale, the effects of certain properties of matter will be very different from the macroscopic state. For example, in the large scale, the diffusion process is often the bottleneck of the chemical process and is difficult to control. However, in the microscale, the diffusion process and its effects may be easier to control. For example, the diffusion coefficient of the protein is relatively small (the diffusion coefficient in water at normal temperature is about ^{8 * 10- 7 cm2 / s)} , the diffusion may take up to ten days through a tube 1 cm in diameter, 10 microns by diffusion but The micropipe takes only one second. Therefore, in the microreactor system, the benefits of size reduction can be fully utilized to fabricate devices such as micromixers.

When the size of one or more spaces in the reactor is compressed to the order of microns, the area to volume ratio of the reactants also varies greatly, giving the microreactor the advantages that the macroreactor does not have:

First, the volume is small, and the reactant consumption is small. The volume of the microreactor is much smaller than that of the conventional reactor system. Due to the small volume of the microreactor, a reaction process can be completed with only a small dose of the reaction. This feature has outstanding advantages for R&D reactors.

Second, the reaction speed is fast. Since the space size of the microreactor is at least one dimension on the order of micrometers, the molecular diffusion distance is short, and the mass transfer is fast, so that the reactants can be quickly contacted, mixed and reacted quickly. Therefore, the reaction rate of the microreactor system is usually much higher than that of the conventional reactor.

Third, the channel is generally laminar, and the fluid flow state is easy to control.

Fourth, the reactor is small in volume, and the heat exchange between the reactants and the outside can be very rapid, and it is easy to confirm this. The reaction temperature is controlled precisely to control the reaction rate. In addition, since rapid heat exchange is possible, some reactions that cannot be performed in a conventional reactor, such as rapid exothermic, flammable and explosive reactions, can be carried out in a microreactor.

5. The microreactor can realize "digital amplification", that is, one channel represents a reactor, and its amplification is only a superposition of numbers, avoiding the amplification effect of the conventional amplification process. Thanks to its "amplification and amplification" characteristics, the microreactor unit has both the stability required for continuous reaction and flexible production adjustment for on-demand production.

Due to the above advantages, the use of microreactors can improve the yield and selectivity of chemical reactions, ensure the safety of the reaction and reduce environmental problems; can greatly reduce the development cost, shorten the development cycle; realize the automation and efficiency of chemical experiments. These advantages of microreaction technology make microreactors have broad application prospects in many fields such as life sciences, energy, and chemicals.

Referring to Fig. 1, a microreactor is disclosed in U.S. Patent No. 6,938,687, which includes a stator provided with a cylindrical bore and a cylindrical rotor which is coaxially mounted in a cylindrical bore of the stator. The opposite cylindrical faces of the rotor and the stator form a narrow annular cavity into which the fluid is injected. The rotor rotates at a high speed, and the large shear force drives the relative movement of the fluid to mix the fluid. The bottom of the rotor of the prior art microreactor is conical. During the rotation of the rotor, due to gravity, fluid that has not been sufficiently mixed often flows out from the bottom outlet of the annular chamber, affecting the mixing and reaction effects. To prevent fluid from flowing out, a common method is to install a valve at the bottom outlet. However, due to the inevitable occurrence of a volume of mixed "blind zone" 900 between the valve and the annular chamber, the fluid in the dead zone 900 cannot be sufficiently mixed to become a waste liquid, resulting in waste of raw materials. In addition, the conical rotor bottom has high precision and difficult machining.

Another microreactor is disclosed in U.S. Patent No. 6,742,774. The structure of the microreactor is similar to the prior art microreactor described above, except that the fluid is fed into the annular chamber from the side wall of the microreactor near the bottom, and is output from the top side wall of the microreactor, and the bottom of the rotor is close to the outlet. flat. When the rotor rotates at a high speed, the centrifugal force at the bottom of the flat rotor causes the fluid to slant toward the side wall of the microreactor in the tangential direction of the rotor, and since the outlet is disposed at the side wall, part of the fluid is drawn into the outlet. To prevent fluid that has not been uniformly mixed from leaking from the output port, a valve is also installed at the output port. When the rotor rotates at high speed, close the valve to prevent fluid leakage. Similarly, due to the inevitable occurrence of a certain volume of mixed "blind zone" between the valve and the annular cavity, the fluid in the blind zone cannot be sufficiently mixed to become a waste liquid, which obviously also causes waste of raw materials.

Therefore, it is necessary to provide a mixing and reaction device to solve the drawbacks of the prior art.

Referring to Figures 2 and 3, the mixing and reaction apparatus of the present invention includes a reaction portion and a driving portion 12. The reaction portion includes a first member 15 and a second member 16, wherein the first member 15 is a stator that is stationary, and the second member 16 is a rotor that can rotate at a high speed. In the present embodiment, the first element 15 and the second element 16 are cylindrical bodies, the first element 15 is provided with a cylindrical hole along its cylindrical axis direction, and the second element 16 is mounted in the cylindrical hole of the first element 15 and An element 15 is coaxial, thereby forming a narrow annular passage 17 between the first member 15 and the second member 16 that can accommodate fluid. The channel 17 is at least one dimension up to the order of meters. In this embodiment, the thickness of the channel 17 is on the order of micrometers, which may be several tens of micrometers to several thousand micrometers. For example, the thickness of the channel 17 can be set to 50 to 80 micrometers. 120~130 microns, 200 microns, 350 microns, 1000 microns, 2000 microns, 3000 microns, etc.

In the present embodiment, the top of the passage 17 is provided with two inlets 30, 31 for inputting the object to be treated to the passage 17, and the bottom is provided with an outlet 18, and the inlets 30, 31 and the outlet 18 can be arranged in the passage according to actual needs. 17 other locations. The inlets 30, 31 and the outlet 18 are each in communication with the passage 17, which may be any element such as a tube or valve that allows the object to be treated to enter or exit the passage 17. The inlets 30, 31 and the outlet 18 may be the same element or arrangement, or may be different elements or arrangements. The outlet 18 can be disposed on the central axis of the passage 17.

Referring to Figures 3 and 4, the second member 16 has a bottom 169. In this embodiment, the bottom 169 surface is a flat surface. The distance between the bottom 169 and the bottom of the stator (i.e., the horizontal portion of the channel 17) is very close, on the order of micrometers, which may be on the order of tens of microns to thousands of microns, for example: the thickness of the horizontal portion of the channel 17 can be set to 50~80 microns, 120~130 microns, 350 microns, 1000 microns, 2000 microns, 3000 microns, etc. When the second member 16 is rotated at a high speed, the centrifugal force provided by the second member 16 produces a radial component that causes the fluid in the horizontal portion of the passage 17 to flow centrifugally along the tangential direction of the bottom 169 of the second member 16, radially Flowing toward the side wall of the first element 15 to seal the fluid in the vertical portion of the passage 17, The fluid in the passage 17 enters the horizontal portion or (and) the outlet 18 of the passage 17, thus preventing fluid from entering the mixing dead zone, allowing all of the fluid within the passage 17 to be thoroughly mixed or (and) reacted. The bottom 169 surface may also be a curved surface having a curvature as long as the bottom 169 provides sufficient centrifugal force to move the fluid radially.

A first flow guiding portion 161 may be disposed on the bottom 169 of the second member 16 for accelerating the radial flow of the fluid. The first flow guiding portion 161 may be integrally formed on the surface of the bottom portion 169 by mechanical processing, electroetching, photolithography or the like, or may be attached to the surface of the bottom portion 169 by plating, strong bonding or the like. The first flow guiding portion 161 may be in any form, for example, it may be a projection provided on the surface of the bottom portion 169, or may be a concave body. The degree of convexity and concavity of the first flow guiding portion 161 on the surface of the bottom portion 169 may be about 1% to 300% of the average thickness of the channel 17, for example, when the thickness of the channel is set to 100 μm, the first flow guiding portion 161 The distance between the most convex portion and the most concave portion in the axial direction of the bottom portion 169 of the second member 16 may be about 1 micrometer to 300 micrometers. In this embodiment, the degree of convexity and concavity of the first flow guiding portion 161 may be preferably set to about 5% to 100% of the thickness of the channel 17, and more preferably set to 10% to 30% of the thickness of the channel 17. about. The degree of convexity and concavity of the first flow guiding portion 161 on the surface of the bottom portion 169 may be the same or different.

The density of the first flow guiding portion 161 on the surface of the bottom portion 169 may be set to be less than 50%. In the present embodiment, the first flow guiding portion 161 may preferably occupy 1% to 40% of the surface area of the bottom portion 169.

The first flow guiding portion 161 may be of any shape. For example, it may be an array of a plurality of dots, which may be continuous stripes or intermittent stripes, or may be composed of dots and stripes. The first flow guiding portions 161 may be randomly arranged on the surface of the bottom portion 169 or may be regularly arranged. The direction of the strip-shaped first flow guiding portion 161 may be arbitrary as long as it is not parallel to the circumferential direction of the bottom portion 169. The stripe-shaped first flow guiding portion 161 may extend from the center of the bottom portion 169 to the edge of the peripheral circumferential surface of the bottom portion 169, or may extend intermittently to the edge of the peripheral circumferential surface. The plurality of stripes may be equally spaced or unequal, and there may be intersections between the plurality of stripes. The first flow guiding portion 161 includes, but is not limited to, a plurality of consecutive equally spaced stripes as shown in Figs.

The cross-sectional shape of the first flow guiding portion 161 includes, but is not limited to, any polygonal shape such as a triangle, a trapezoid, a square, or the like, a semicircular shape, a semi-elliptical shape, or the like, or any combination of the above shapes.

The trend direction of the first flow guiding portion 161 may be arbitrary as long as the trend direction is overall Similarly, it is sufficient to generate a thrust in the direction of the flow. The thrust creates a radial component that is parallel to the radius of the first element 15 and urges the fluid to flow in a radial direction. The fluid in the horizontal portion of the passage 17 is caused to flow radially toward the side wall of the first member 15, thereby sealing the fluid in the vertical portion of the passage 17, preventing fluid within the passage 17 from entering the horizontal portion of the passage 17 or (and) the outlet 18. In this way, all fluids can be confined in the vertical portion of the passage 17, ensuring that the fluid has sufficient time to mix and react within the passage 17, and to prevent fluid from entering the mixing dead zone, thereby ensuring passage 17 All fluids are thoroughly mixed or (and) reacted. When the fluid is sufficiently mixed or (and) reacted in the passage 17, the fluid can be lowered to the product outlet 18 by pressurization from the top of the passage 17.

The second component 16 facing the sidewall of the channel 17 may be provided with a second flow guiding portion 160, and the second guiding portion 160 may be integrally formed on the surface of the second component 16 by machining, electroetching, photolithography or the like. Further, it may be attached to the surface of the second member 16 by plating, strong bonding, or the like. The second flow guiding portion 160 may be in any form, for example, may be a projection provided on the surface of the second member 16, or may be a concave body. The degree of convexity and concavity of the second flow guiding portion 160 on the surface of the second element 16 may be about 1% to 300% of the average thickness of the channel 17, for example, when the thickness of the channel is set to 100 μm, the second flow guiding portion The distance between the most convex portion and the most concave portion of 160 in the radial direction of the second member 16 may be about 1 micrometer to 300 micrometers. In this embodiment, the degree of convexity and concavity of the second flow guiding portion 160 may preferably be set to about 5% to 100% of the thickness of the channel 17, and more preferably, the thickness of the channel 17 is set to lO^^SO^ about. The degree of convexity and concavity of the second flow guiding portion 160 on the surface of the second member 16 may be the same or different.

The density of the second flow guiding portion 160 on the surface of the second member 16 may be set to be less than 50%. In the present embodiment, the second flow guiding portion 160 may preferably occupy 10 to 40 of the surface area of the second member 16.

The second flow guiding portion 160 may be of any shape. For example, it may be an array of a plurality of dots, which may be continuous stripes or intermittent stripes, or may be composed of dots and stripes. The second flow guiding portions 160 may be randomly arranged on the surface of the second member 16, or may be regularly arranged. The direction of the stripe-shaped second flow guiding portion 160 may be arbitrary as long as it is not perpendicular or parallel to the axial direction of the second member 16. The stripe-shaped second flow guiding portion 160 may extend from the bottom of the second member 16 to the top or may extend intermittently to the top. Multiple stripes can be equal The distance may also be unequal spacing, and there may be intersections between the plurality of stripes. The second flow guiding portion 160 includes, but is not limited to, a plurality of consecutive equally spaced stripes as shown in FIG.

The cross-sectional shape of the second flow guiding portion 160 includes, but is not limited to, any polygonal shape such as a triangle, a trapezoid, a square, or the like, a semicircular shape, a semi-elliptical shape, or the like, or any combination of the above shapes. The triangular second flow guiding portion 160 shown in Fig. 4 is only one of them.

Referring to Fig. 4, in the present embodiment, the second flow guiding portion 160 is a continuous stripe. When the second member 16 is rotated, the intersection of a continuous stripe of the second flow guiding portion 160 and the cut surface of the surface of the second member 16 is continuously moved. The direction of movement of the intersection is the trend direction of the stripe. The direction of the second flow guiding portion 160 may be arbitrary as long as the direction of rotation is substantially opposite or the same as the direction of rotation of the second member 16. When all or a portion of the strips on the second element 16 have the same tendency direction, a force in the direction of the flow is generated to the fluid. The thrust creates an axial component that is parallel to the central axis of the first member 15 and urges the fluid to flow axially.

The object to be treated enters the annular passage 17 through the inlets 30 and 31. The two components to be treated are quickly and thoroughly mixed under the action of the high shear force, high centrifugal force and axial force of the second member 16. If the two fluids can react chemically, they can be fully mixed and fully reacted.

In the mixing and reaction apparatus of the present invention, the fluid flow in the passage 17 may be laminar, possibly turbulent. The power provided by the high-speed rotation of the second element 16 drives the fluid to flow in layers, dividing the fluid into a plurality of thin layers. In the radial direction of the annular passage 17, the fluid layer can be quickly and otherly due to the different flow speeds between the thin layers. The fluid layers are in close contact, resulting in rapid diffusion, allowing the two fluids to mix well. However, according to the "Taylor Coutte Flow" theory, after the reaction part is manufactured to a certain size, the gap of the passage 17 is fixed, and whether the fluid of different viscosity occurs at different rotation speeds The Coulter flow or Taylor vortex is determined by the Taylor coefficient. When the rotor is running at low speed, the fluid flow in the channel 17 is laminar flow, then the fluid mixing effect is better, but due to the low speed, the input The flow rate of the fluid to be mixed cannot be high. If the flow rate is high, the fluid quickly flows out through the passage 17 in the axial direction, and the mixing effect is not achieved. In order to mix with high efficiency and high flow rate, the rotation speed of the rotor must be increased. Increasing the rotational speed may result in a Taylor vortex. The mixing effect is deteriorated. The mixing and reaction device of the present invention does not avoid the generation of Taylor vortex, the axial force provided by the second flow guiding portion 160 of the second member 16, Come Disturbing the Taylor vortex arranged in a direction perpendicular to the axis of the second element 16 breaks the closed fluid mass formed by the Taylor vortex, thereby causing the fluid in the vortex to communicate with the fluid outside the vortex, thereby increasing the mixing effect. On the other hand, the second flow guiding portion 160 also disturbs the self-contained circulation in the vortex, causing the fluid in the circulation to agitate and mix. From this, it can be seen that since the flow guiding portion 16 is provided on the second member 16, the mixing effect of the mixing and reaction device of the present invention can be prevented from being affected by the input flow rate and the number of revolutions. The particles of the fluid mixed by the mixing and reaction device of the present invention are very small, and the radius can reach the nanometer level, which greatly improves the mixing efficiency and reaction efficiency of the fluid.

The second flow guiding portion 160 has a function of controlling the retention time of the fluid in the passage 17 in addition to the function of disturbing the Taylor vortex and increasing the mixing effect. The trend direction of the second flow guiding portion 160 may be opposite to the rotation direction of the second member 16, and when the second member 16 rotates at a high speed, the second flow guiding portion 160 provides an upward axial force to prevent the fluid in the passage 17 from falling to The horizontal portion of channel 17 or (and) the outlet 18. In this way, all of the fluid can be confined within the vertical portion of the passage 17, ensuring that the fluid has sufficient time to mix and react within the passage 17, and to prevent fluid from entering the mixing dead zone, thereby ensuring that all of the passages are within the passage 17. The fluid can be thoroughly mixed or (and) reacted. When the fluid is sufficiently mixed or/and reacted in the passage 17, it can be pressurized from the top of the passage 17 to reduce the fluid helium to the product outlet 18; or, the second member 16 can be reversely rotated, that is, the second diversion The direction of the direction of the portion 160 is the same as the direction of rotation of the second member 16, and the second flow guiding portion 160 provides a downward axial force to cause fluid to drop to the product outlet 18.

Based on the same principle, the flow guiding portion 18 can also provide the above functions when it is necessary to invert the reaction portion in some cases.

As apparent from the above, the flow state of the fluid can be controlled to some extent by the axial force of the second flow guiding portion 160. This includes, but is not limited to, controlling the retention time of the fluid in the reaction section, promoting the flow of fluid out of the reaction section, changing the rate at which the fluid flows out of the reaction section, increasing or decreasing the resistance of the fluid to be injected into the reaction section, and the like.

The mixing and reaction apparatus of the present invention may further include a connecting portion 13 and a bearing housing 11 mated with the second member 16, the second member 16 being coupled to the shaft of the driving portion 12 via the connecting portion 13, and the second member 16 passing through the bearing housing 11, An annular passage 17 is formed with the first element 15.

The mixing and reaction apparatus of the present invention may include means for connecting the driving portion 12 and the second member The connecting portion 13 of the 16 is such that the driving portion 12 can drive the second member 16 to rotate. The drive portion 12 can be an electric motor or any other component that can provide power to rotate the second member 16. The maximum rotational speed of the second element 16 is mainly determined by the power and torque of the drive unit 12. Generally, the higher the power and torque of the driving portion 12, the larger the rotational speed of the second member 16. In the present embodiment, the maximum rotational speed of the second member 16 is 10,350 rpm. Depending on the characteristics of the fluid, choosing the appropriate speed or higher can achieve the desired or even better results of the mixing or (and) reaction. Generally, when the rotational speed of the second element 16 is higher than 3000 rpm, for example, 3000 rpm, 5000 rpm, 6000 rpm, 8000 rpm, 9000 rpm, etc., the particle radius of the product can be reached. Rice or nanoscale. According to actual needs, the appropriate driving portion 12 is selected, and the mixing and reaction device of the present invention can achieve a higher rotational speed. The operating temperature of the reaction unit can be set between -150 ° C and 300 ° C. For example, the operating temperature of the reaction unit is set at -150 ° C to 50 ° C and -50 ° C to 100. C, 20 ° C ~ 250. C, 150 ° C ~ 300 ° C and so on.

The mixing and reaction apparatus of the present invention may further comprise one or more first temperature control portions 14. The first temperature control portion 14 may be provided at part or all of the periphery of the passage 17, and may be installed at other positions of the reaction portion. The first temperature control portion 14 may include openings 32, 33 such as valves or tubes, through which the first temperature control portion 14 may be filled with a fluid to rapidly change the temperature of the reaction portion. Since heat may be generated in the mixing reaction, heat may also be absorbed, and the fluid circulates from the inlet 32 into the first temperature controller 14 of the reaction portion, and after sufficient heat exchange, flows out from the outlet 33, thereby circulating heat or bringing in heat. When the second member 16 is rotated at a high speed, the shearing friction may cause a large amount of heat to be generated in the fluid in the passage 17. To prevent this heat from affecting the mixing reaction, the cold fluid is circulated into the first temperature control portion 14 through the opening 32, and is sufficiently exchanged with the passage 17 to flow out from the outlet 33. If the chemical reaction in the passage 17 needs to absorb heat, and when the heat generated by the friction is insufficient to supply, the first temperature control portion 14 may be charged with a circulating fluid having a high temperature, and the high-temperature circulating fluid may heat the passage 17. Since the walls of the passage 17 and the first member 15 are both thin, the circulating fluid of the set temperature can be rapidly exchanged with the fluid being mixed, and the fluid being mixed in the passage 17 can be quickly circulated with the circulating oil. The temperatures are close. Moreover, since the channel 17 is narrow, the temperature of the fluid in the channel 17 is easily homogenized, which facilitates the consistency of the reaction. By controlling the temperature of the channel 17 by the first temperature control unit 14, some mixed reactions can be satisfied. The temperature in channel 17 is also guaranteed to be constant for specific temperature environments.

The mixing and reaction apparatus of the present invention may further comprise one or more second temperature controls. The second temperature control portion is disposed on the bearing housing 11. The second temperature control portion may include openings 34, 35 such as valves or tubes. Through the openings 34, 35, the second temperature control portion can charge the bearing housing 11 with fluid such as oil, water, etc., to rapidly change the temperature of the shaft 7 seat 11. When the second component 16 is operated at a high speed, the bearings in the bearing housing 11 heat up, fluid enters the bearing housing 11 from the inlet 34, flows out of the outlet 35, removes heat, and lubricates the bearing. Since the top of the second member 16 projects into the bearing housing 11, the second temperature control portion also has the function of controlling the temperature of the second member 16. Depending on the set temperature in the passage 17, the temperature of the second temperature control portion is appropriately set to ensure that the temperature of the top of the second member 16 is the same as the temperature at the bottom of the second member 16 that projects into the passage 17. Thus, heat conduction due to the temperature difference between the top and bottom of the second member 16 is avoided, resulting in heat loss or heat increase of the passage 17.

The mixing and reaction apparatus of the present invention may further comprise one or more third temperature controls. The third temperature control unit is provided on the drive unit 12. The second temperature control portion may include openings 36, 37 such as valves or tubes. Through the openings 36, 37, the second temperature control portion can charge the driving portion 12 with fluid to rapidly change the temperature of the driving portion 12. The heat from the driving portion 12 is discharged from the opening 37 after entering the driving portion 12 from the opening 36. For example, when the drive unit 12 generates a large amount of heat at a high speed, the drive unit 12 can be cooled by water cooling.

The mixing and reaction apparatus of the present invention is mounted on a station (not shown) by means of a support device, and the angle of installation can be vertical, horizontal or any desired angle. The supporting device may include a base 9 and a support base 10, wherein the base 9 is mounted on a console for fixing the driving portion 12 and the reaction portion to the base 9.

Referring to FIGS. 7 and 8, the cross-sectional area of the second member 16 may be elliptical or polygonal, such that when the second 'element 16 is rotated at a high speed, the width and width of any one of the fixed positions in the channel 17 follow the second element 16. The rotation is changed, and accordingly, the fluid in the passage 17 is thereby unevenly pressed, thereby achieving thorough mixing. Of course, the cross-sectional area of the second member 16 may be other shapes, and the ellipse or polygon shown in Figs. 5 and 6 is only two of them.

The second member 16 may not be coaxial with the first member 15, and the shaft of the second member 16 may be parallel or intersect with the first member. Based on the similar principles described above, the fluid in the passage 17 is also subjected to uneven compression to achieve sufficient mixing. In other embodiments of the mixing and reaction apparatus of the present invention, the first element 15 and the second element 16 are interchangeable, i.e., the second element 16 is a stationary stator and the first element 15 is a rotor that can rotate at a high speed. . The first element 15 and the second element 16 may be elements that rotate in opposite directions, or may be elements that rotate at different speeds. The first and second members 15, 16 may also be elements of any shape that are close to each other, such as a sheet body that is close to each other, as long as a narrow passage 17 that can accommodate a fluid is formed therebetween. The second flow guiding portion 160 may be selectively disposed on the first member 15 or (and) the second member 16. When the substance to be treated is already a mixed liquid, the mixing and reaction apparatus of the present invention may be provided with only one inlet of the object to be treated; when a plurality of objects to be treated require mixing and reaction, a plurality of inlets for the object to be treated may be provided. The mixing and reaction apparatus of the present invention may also be provided with a plurality of inlets to be treated in advance, and an appropriate number of inlets for the objects to be treated are selected according to the needs of the reaction.

The various components of the mixing and reaction apparatus of the present invention may be made of the same or different materials. The components of the mixing and reaction device of the present invention may be made of a metal material such as cast iron, stainless steel, alloy, aluminum, etc., depending on factors of the property to be treated, product characteristics, reaction or (and) required conditions of the mixing process, cost, and the like. It is made of organic materials such as plastic, glass, and quartz glass, and can also be made of inorganic materials such as ceramics. For example, in the present embodiment, the first member 15 and the second member 16 are made of stainless steel, so that the mixing of the present invention and the reaction device can be applied to a highly corrosive object to be treated.
