The number of dirt module 5 is three, and two electrion modules are respectively electrion module 6a and electrion module 6b.Purification
During flue gas, flue gas enters inside shell 1 from gas inlet 2, along exhaust gases passes 4 successively electrion module 6a, the
One board-like dust collection module 5, electrion module 6b, second board-like dust collection module 5, third board-like dust collection module 5 and
Porous ceramic plate 7 is finally discharged from exhanst gas outlet 3.Each electrion module during flue gas passes through for making flue gas
In particle carry positive charge, each board-like dust collection module 5 be used for by electrostatic field and magnetic field make carrying positive charge particle
It is deposited in board-like dust collection module 5, with the air and contaminant particle in separating flue, to realize the mesh of gas cleaning
's.
As shown in Figure 1, 2, 3, electrion module 6a is similar with the structure of electrion module 6b, if the two is provided with
The metal circular tube 8 passed through for flue gas is done, electric discharge stylus 9, metal circular tube 8 and electric discharge stylus 9 are coaxially arranged in metal circular tube 8
It is electrically connected respectively with the cathode of power supply 15 and anode；There is electric field, flue gas between metal circular tube 8 and electric discharge stylus 9 after energization
During flowing through metal circular tube 8, electric-field charge and diffusional charging are realized when the soot dust granule in flue gas moves in its electric field,
Keep the soot dust granule of flue gas positively charged.
Specifically, electrion module further includes negative conductive plate 10, positive conductive frame 11 and insulation connecting column 12；It is negative
Pole conductive plate 10 is arranged in parallel with positive conductive frame 11, is connected with several eradication edge connecting columns 12 therebetween.Metal circular tube 8 is pacified
On negative conductive plate 10, the opening for accommodating metal circular tube 8 is provided on negative conductive plate 10.The one of metal circular tube 8
End is air inlet 13, and the other end is air outlet 14.In the present embodiment, the axis of metal circular tube 8 and negative conductive plate 10 and
Positive conductive frame 11 is vertical, and the air outlet 14 of metal circular tube 8 is towards positive conductive frame 11.Positive conductive frame 11 is in lattice-shaped, is put
One end of acusector pole 9 is tip, is extended in metal circular tube 8, the other end is stated positive conductive frame 11 and is fixedly connected.
Negative conductive plate 10 and positive conductive frame 11 are each made of a metal.The axis weight of electric discharge stylus 9 and metal circular tube 8
It closes, electric discharge stylus 9 is equal to the arcing distance of 8 inner wall of metal circular tube everywhere, can be formed after energization strong from axial line to inner wall
The disc high intensity electrostatic field gradually to successively decrease, will not generate low field intensity dead angle, select suitable voltage, also can be effectively controlled by
In the ozone burst size that air ionization generates.
The outside of shell 1 is provided with power supply 15, the anode and cathode of power supply 15 respectively with positive conductive frame 11 and cathode
Conductive plate 10 is electrically connected.Power supply 15 leads to negative voltage to negative conductive plate 10 for leading to positive voltage to positive conductive frame 11.It is powered
Afterwards, electric discharge stylus 9 and metal circular tube 8 form disc high intensity electrostatic field.Under the action of electric field force, the cigarette in flue gas
Dirt particle is then adsorbed, and microorganism is then ionized under the action of high field by cathode by charged and positively charged
Carbonization is killed.
Specifically, positive conductive frame 11 is to connect the lattice-shaped structure formed by several conducting rods 16 staggeredly intersected.Just
Pole conduction rack 11 forms the circulation gap 17 passed through for flue gas at the air outlet 14 of metal circular tube 8.
The ratio that electric discharge stylus 9 extends the length for entering length and metal circular tube 8 in metal circular tube 8 is 3:4 to 5:6.
The reason of choosing this setup is, if the needle point of electric discharge stylus 9 is too close away from the air inlet 13 of metal circular tube 8, can make from
Sub- wind can become smaller, and corona is unstable, and ionized region can be thinning, influence soot dust granule and microorganism passes through the positive charge and electricity of when institute's band
From degree, soot dust granule and microorganism is caused not to be ionized effectively, or it can not be made with the positive electricity adsorbed enough by accumulation area
Lotus；If air inlet 13 of the needle point for the stylus 9 that discharges apart from metal circular tube 8 is too far, the lumen of metal circular tube 8 is close to air inlet 13
A part of tube body just can not generate ionized region with the electric discharge cooperation of stylus 9, this section of lumen also just loses its use value, collect at this time
The region in dirt area also can accordingly reduce, and dust removing effects can decline.If needle point goes beyond the scope, dust collecting effect can it is proportional under
Drop.
In the present embodiment, each metal circular tube 8 in electrion module is in honeycomb close-packed arrays.Electrion module 6b
Main function be positive charge entrained by the soot dust granule that enhances in flue gas quantity, however the sky between each metal circular tube 8
Electric field strength in gap is 0, and during flue gas flows through electrion module 6b, partial fume flows through between each metal circular tube 8
Gap so that the soot dust granule in this partial fume can not obtain more positive charges.By blocking between each metal circular tube 8
Gap can solve this problem, but simple blocking will increase the windage of electrion module 6b.
In order to solve blind area caused by the gap between metal circular tube 8, charged particle is introduced in electrion module 6b
Guide pin 18.Charged particle guide pin 18 is the main distinction between electrion module 6a and electrion module 6b.Electrification
