With reference to the accompanying drawings, a kind of ion wind type electric precipitation of the present invention, mainly by dust collector box body（1）, air inlet（2）, air-out
Mouthful（3）, air intake horn mouth（4）, anode superstructure（6）, cathode frame（7）Composition, the dust collector box body（1）Both ends set respectively
There is air inlet（2）And air outlet（3）, in dust collector box body（1）With air inlet（2）Between be installed into air horn mouth（4）, anode frame
Frame（6）And cathode frame（7）It is arranged in dust collector box body（1）Inside, anode superstructure（6）It is directly connected to casing big frame, it is cloudy
Pole framework（7）It is connected by insulator with casing big frame；
In the adjacent air intake horn mouth（4）Dust collector box body（1）It is internally provided with air flow method section（41）, air flow method section
（41）If being the sheet material that W shapes are converted into by dry plate, it is laminated according to certain interval, and is arranged perpendicular to airflow direction, forms a plurality of song
The gas channel of folding.Air-flow passes through air flow method section（41）After a plurality of gas channel, whole casing, gas are uniformly spread in
The larger grit of proportion falls on flue-dust retainer under after colliding gas channel wall when the direction of motion is varied multiple times in stream, simultaneously
The probability for also increasing dust and being come off from air-flow is reduced because gas channel section increases air-flow velocity.
The anode superstructure（6）Using shaped steel welding fabrication, in lower portion, along airflow direction, longitudinally anode is installed in suspension
Board mount（61）, anode board mount（61）" n " font outer framework, the groove profile mouth court of shaped steel are welded into using C40-C60 shaped steel

The present invention minus plate and positive plate interlaced arrangement, between region formed exhaust gases passes, accessed when for minus plate
The negative pole of high voltage power supply, positive plate access high voltage power supply positive pole when, flue gas through air inlet in the presence of air flow method section,
It is even to be distributed to each exhaust gases passes, into exhaust gases passes dust negative electrode prickle it is charged after, and in the presence of corona wind through sun
Pole plate mesh to positive plate inside drive into；Due to the effect of corona wind and anode wooden partition online eye, the dust of low resistivity loses
The phenomenon bounced and disturbed on anode, while the back corona phenomenon of anode plate surface high resistivity dust is in the work of corona wind
Firmly enter inside dust chamber down, efficiently avoid the back corona phenomenon of anode plate surface, therefore can be as far as possible
Anode-cathode distance is reduced, so as to significantly increase dust-collecting efficiency, the particularly dust-collecting efficiency to subparticle；Into inside positive plate
Dust mutually collide, condense, tie grain, be collected outward transport in ash bucket through the vertical channel final settlement among positive plate；Individually
The dust being attached on anode expanded metals wall, and indivedual dust being attached on minus plate carry out height by opening pneumatic vibrator
Frequency vibrations come off.
The present invention is organically acted on using corona wind and dust is confined to inside the positive plate of cavity, so as to reduce flue gas
Turbulence intensity in passage, improves dust collection effect；Dust size is smaller under dizzy wind action simultaneously, and its dust collecting performance is got over
By force；Secondly the present invention is not restricted by dust specific resistance size；Dust into dust chamber also has good hydrodynamics screen
The effect of covering, loss of backflowing can be efficiently reduced；The dust collection electric field of this configuration flutters dirt efficiency high, airborne dust loss than conventional electric field
