In order to improve the dust-collecting efficiency of electric cleaner to fine dust, Chinese scholars has been made number of research projects, mainly concentrates on coalescence mechanism, method and the coalescence device development to fine particle.The three-region type static coalescence deduster that Watanabe and Suda propose has caused concern (the Watanabe T in dedusting technology field, Suda T.Submircron Size CarbonicParticle Agglomeration by an Electrostatic Agglomeration Apparatus, Proc.3rd.Internat.AerosolConf.M, Kyoto, Japan, 1990,749-752).Subsequently, people such as Watanabe have done more comprehensive experimental study to this three-region type electricity coalescence deduster, experimental result shows: the flying dust of handling 0.06～12 μ m, dust-collecting efficiency than conventional electric cleaner improves 3%, promptly 95.1% is increased to 98.1% (Watababe T, et al.Submicron Particle Agglomeration by an ElectrostaticAgglomeratorJ, J Electrostatics, 1995,34 (4):, 367-383).Yet what Watanabe adopted is the coalescence method of the charged dust of same polarity in alternating electric field.According to static condensation and mechanism,, can further improve the coalescence effect if in alternating electric field, adopt the charged dust of heteropolarity.So, many researchers have discussed and have realized the charged method (KanazawaS of particulate heteropolarity, et al.Submicron Particle Agglomeration and Precipitation by Using a Bipolar Charging MethodJ, J.Electrostatics, 1993,29 (3) 193-209; Koizumi Y, et al.Bipolar-charged Submicron ParticleAgglomeration lJ, J Electrostatics, 1995,35 (2): 55-60), and the theory and experimental study (the Kilde J of the charged dust of heteropolarity coalescence in alternating electric field have been carried out, et al.An Experimental Investigation for Agglomeration of Aerosols inAlternating Electric FieldJ, Aerosol Sci.and Techn., 1995,23 (7): 603-610; Kari E J, et al.Kinematics Coagulationof Charged Droplets in an Alternating FieldJ, Aerosol Sci.and Techn., 1995,23 (3), 422-430).
The coulomb coalescence principle of the charged dust of heteropolarity is, fine dust in pre-charging area lotus with the electric charge of heteropolarity, be that a part of particle lotus is with positive charge, and another part lotus is with negative electrical charge, enter then in the coalescence district, in the coalescence district, the dust of band heteropolarity electric charge is gathered into bigger particle under the effect of Coulomb force, enters in the dust collection section then to be captured down.
The coalescence dust arrester of the charged dust of heteropolarity in alternating electric field is, adopt the pre-charged mode of heteropolarity, accelerate the relative motion of the charged dust of heteropolarity in alternating electric field, helped the attracting each other of charged dust, collision, coalescence, thereby improved coalescence speed.
The various electric coalescence dedusting technology that above research institute proposes does not still obtain real practical application at present owing to be subjected to the influence of each side factor, and major influence factors is an one side structure more complicated, and the coalescence effect is limited on the other hand.
