SMOKE-DISPENSER.

To all whom it may concern:

I Be it known that I, MILTON Mosnn, a

citizen of the United States, and a resident of Ladysmith, British Columbia, Canada, have made certain new and useful Improve ments in Smoke-Dispensers, of which the following is a specification:

My invention relates to smoke dispensers of the type in which the smoke, formed in a furnace or'analogous structure, is brought into contact with a. liquid and thus prevented from being set free in the atmoshere. p More particularly stated, I seek to produce a smoke dispenser adapted for-general use, but of peculiar service in connection with smelting furnaces and other analogous devices, and so arranged as to bring the smoke into contact with water under such conditions as to cause the smoke to be absorbed by the water.

My invention further relates to saving the various waste products containedv in smoke, and particularly acid fumes and metallic vapors found in the's'fiiok'e of smelting furnaces, thus not only promoting economy in'saving waste material, but also preventing noxious and destructive substances from being allowed to contaminate the atmosphere. y I

Reference is made to the accompanying drawings forming a part of this specification, and in which like letters indicate like parts. Y

Figure 1 is a view partly in side elevation and partlyin. section, showing 111 dispenser complete. Fig. 2 is a agmentary central section through the aspirating' mechanism forming a part of my device. Fig. 3 is a detail, being a lan view of .the centrifugal condenser an separator em-- ployed. Fig. '4 is a side elevation of the device shown in Fi 3. Fig. 5 is a section on the line 5-5 0 Fig. 2, looking in the direction of. the arrow. Fig. 6 is a section substantially on the line 66 of Fig. 2, looking in the direction of the arrow.

A smoke pipe is shown at 7 and may be connected directly to the smoke stack of a furnaceg Encircling a vertical portion of the pipe 7 and secured to the latter is a spider 8, and connected rigidly with this pider is a casing 9. This casing is made in halv'es secured together by bolts 10', and is provided with an annular passage 11. The casing is further providedwith a single i Specification of Letters Patent.

' large annular nozzle 12, fed by the annular passage 11, andextending downwardly therefrom, as will be understood from Fig. 6. The casing 9 is further provided with an annular flange 13, which is secured upon 'and supported by a tower 14. This tower is of frusto-conical form and is supported upon a pedestal 15 of masonry. Mounted upon the ,tower 14 are a number of braces 16, and. supported upon these braces is,a

- ring 17, this ring being connected by a number of pipes 18 with the casing 9, thepipes extending directly into the annular pas-- sage 11.

The pipes 18 are each provided with an angular portion 19 and with threaded ends, so that by applying a wrench to' the angular portion and turning the pipe, the ring 17 may be adjusted to some extent relatively to the casing 9. The casing 9-supports a number of air tubes 20, which extend inwardly and downwardly and at tllieir 1lower ends are provided with nozz es 2 Acylindrieal jet 22 of water iscontinular nozzle 12. A bafile 23, having substantially the form of a double. cone, is located within the cylindrical jet 22, and concentric to the same. This baflle is supported upon braces 24, and these braces are sup orted within a casing 25. Fitted within the casing are a number of blades 26, each being comparatively wide at its bottom and narrow at its top, the peripheral tops'of the blades being curved parabolically as indicated by full lines in Fig. 3-, and by dotted lines in Fig. 4.

The lower end of the baflie 23, being conical, is fitted directly'against the adjacent inner edges of the lower portionsof the blades 26. Encircling the upper end of the bafiie 23 isa pipe 27 havinga substantially funnel shaped portion 28 which is concentrio to the adjacent conical surface of the bafile, asmay be understood from Fig. 2.

Located within the bottom of the tower 14 is a funnel 29, and connected with this funnelis a discharge pipe 30. The funnel and discharge pipe are used for the purpose of saving the waste products, as hereinafte described. A pipe 31 is connected with the tower 14 and with a stack 32. This stack rests upon the pedestal 15 and extends upwardl'y therefrom and at its top opens into the atmosphere. The casing 9 is provided with a number of openings-33, and located adjacent to each of these openings is a door 34. These doors may be opened to any desired extent by hand, independently of each other (see Fig. 1) and in this manner the capacity of the openings 33 for admitting air to pipe 20, may be controlled at will. The pipe 27 may be connected to a hydraulic supply, and used for thepurpose of admitting cold water in order to cool the baflle 23 and various other parts of the tower.

The ring 17, which is essentially an annular tube, is connected with a pipe 35, through which water is supplied into the ring 17. The ring 17 is essentially a distributing ring for supplying water into the annular passage 11, this arrangement being such as to equalize the pressure in the different pipes 18, and thus insurean equal pressure of water in different portions of the annular passage/11. This also insures that substantially equal quantities of water will be discharged from diderent portions of the nozzle 12.

When water is supplied freely through the pipe 35 and into the hollow ring 17 so as to flow through the pipes 18 into the annular passage-11, this water is discharged in the general form of a cylindrical jet 22, as above stated. The water thus flows essentiallv in the form of a substantially uniform sheet having theform of a cylinder 22. The water runs down. and at the bottom of this c linder flows intothe casing blades 26.

and is distributed between the various At the same time that this occurs. a stream of water from the pipe 27 is distributed over the baffle 23. and flows downwardlw upon the same. This supply of water ultimately reaches the blades 26.

The operation of m device is as. follows: The parts being assembled and arranged as abo e described. and the water being turned on. in the pipe and the tube 27, and the smoke from the furnace being directed through. the pipe 7 this smoke is brou ht into minute contact with the water. The

-' smoke as it leaves the pipe 7 is forced into over the bafile'23.

the cylindrical iet 22 of water. the smoke being thus dispensed or condensed. The smoke is further forced into contact with the water as the smoke passes downwardly Any smoke not thus condensed is condensed in passin with the water, through the casing 25. The water, being virtually spread into the form of a thin sheet. has a comparatively large surface which is brought into minute contact with the smoke. The smoke isthus absorbed by the water.

The forcible discharge of water from the nozzle 12-produces an aspirating edect upon the air contained in the casing 9, and the tower 14, so that this air is formed into a down draft. This down draft, by suction,

draws smoke continuously into .and through the pipe 7. As the down draft, permeated of course with the smoke and the impurities appearing as in redients in said smoke, passes downwar y through the casing 25, it is given a whirling motion by virtue of the form of the blades 26. The water, now containing the smoke held by absorption if not in solution, drops into the funnel 29 and is discharged into the pipe 30. From the water thus discharged any valuable ingredients present may afterward be separated by evaporation or by any other suitable manner, and thus saved. The residuum of the smoke, containing mostly air and carbonic acid gas, now passes over into the stack 32 and thence makes its escape into the atmosphere.

I find that owing to the shape of the blades 26, the whirling motion they give to the down draft facilitates the absorption of the smoke by the water. ll also find that a little air atted through the air tubes 20 facilitates this purpose.

I do not limit myself to the precise mechanism shown, as variations may be made therefrom without departing from the spirit of my invention.
