Identical appended drawing reference denotes same or similar part or part in attached drawing.It should be appreciated by those skilled in the art that these
What attached drawing was not necessarily drawn to scale.In attached drawing：
Fig. 1 is the schematic diagram of waste gas purification apparatus according to an embodiment of the invention.
Specific embodiment
Fig. 1 is the schematic diagram of waste gas purification apparatus according to an embodiment of the invention.As shown in Figure 1, this hair
Bright waste gas purification apparatus, including particulate matter charge unit 1, coagulation and unit 2 and electric precipitation unit 3.Particulate matter charge unit 1
For keeping particle charged when flowing through the high voltage corona electric field between electrode；Simultaneously unit 2 is set under particulate matter charge unit 1 coagulation
Trip, for by small particle coalescence at large particle, large particle by the particle after charged by intergranular inertial collision,
Grain diffusion, space-charge force, the attraction of intergranular heteropolarity, between particle or the elephant power of particle and wall surface makes minuteness particle coalescence；
Electric precipitation unit 3 is set to coagulation and 2 downstream of unit, by making gas ionization using electrostatic field to make large particle be adsorbed onto
On electrode.Indoor exhaust air purification device of the invention improves its treatment effect to indoor exhaust air using coagulation and unit 2.
In one embodiment of the invention, simultaneously unit 2 is used for partial size in 3 μm of particulate matter coalescences below into 3 μ coagulation
The large particle of m or more.
In one embodiment of the invention, coagulation and unit 2 use the carrying capacity and benefit for improving anisotropic charged particle thing
Make every effort to promote with Coulomb force collision coalescence, by the reversed electric field of alternating electric field into the collision coalescence of same sex charged particle thing and by logical
The electric field force and Coulomb force for crossing alternating electric field promote any one in anisotropic charged particle thing collision three kinds of coalescence modes of coalescence.
