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, the positive pole and reliable ground of rectifier transformer are connected, in framework
It is internal that along airflow direction, longitudinally positive plate net cage is installed in suspension（62）, the positive plate net cage（62）Thickness is used as 2-3 millimeters
Carbon steel plate be evenly arranged eyelet, eye diameter is 3-5 millimeters, the spacing between eyelet and eyelet be 3-5 millimeters formed plate
Net, then it is molded into the corrugated rectangular box that surrounds again of arcuation and is formed；In positive plate net cage（62）Windward side is vertically arranged three
Angle-style air-resistance cover（61）, triangular form air-resistance cover（61）Fixed in vertical direction at interval of 2-5 rice and anode superstructure at one, in anode
Expanded metals case（62）Leeward end anode superstructure（6）On be vertically arranged stopper slot（63）, positive plate net cage（62）With triangular form air-resistance cover
（61）, stopper slot（63）Between leave expansion gap；In the positive plate net cage of rectangular box shape（62）Internal arcuation arches upward
Middle set deashing electrode（5）, deashing electrode（5）Using pole type carbon steel, deashing electrode（5）With positive plate（62）It
Between use insulating support（51）Support, insulating support（51）In vertical direction, every 1.5 meters -3 meters set 1；Insulating support（51）
The strip being fabricated to for insulation nonmagnetic substance, it is provided with passes through deashing electrode among it（5）Circular hole, Circularhole diameter is more than clear
Grey electrode（5）External diameter, and leave the bump clearance, both ends and positive plate net cage（62）It is fixed；Deashing electrode（5）Be cross-linked through
The high-frequency alternating power supply of frequency converter modulation, the asterism ground connection of alternating source.
The cathode frame（7）Using shaped steel welding fabrication, and through insulator（71）It is installed on main frame, in negative electrode frame
Inside frame installation negative electrode prickle wire is hung along airflow direction longitudinal arrangement（72）, cathode frame（7）Connect the negative of rectifier transformer
Pole output end；
The positive positive plate net cage（62）With negative electrode prickle wire（72）Uniform interlaced arrangement, positive plate on parallel to airflow direction
Net cage（62）With negative electrode prickle wire（72）Net die opening be 100-200mm.
Refering to accompanying drawing 1, negative electrode prickle wire of the invention and positive plate net cage interlaced arrangement, the installation site face of prickle wire
The recessed position arrangement of positive plate net cage plate face, and keeps uniform arcing distance, between region form exhaust gases passes, enhancing
The charged probability of flue dust, when the negative pole of high voltage power supply is accessed for cloudy prickle wire, positive plate net cage accesses the positive pole of high voltage power supply
When, flue gas in the presence of air flow method section, is evenly distributed to each exhaust gases passes through air inlet, and the dust into exhaust gases passes is cloudy
After pole prickle is charged, and in the presence of corona wind through positive plate mesh to positive plate inside drive into；Due to corona wind and sun
The effect of mesh on pole plate wall, the dust of low resistivity lose the phenomenon bounced and disturbed on anode, while positive plate table
The back corona phenomenon of face high resistivity dust has been entered inside dust chamber under the active force of corona wind, efficiently avoid sun
The back corona phenomenon of polar board surface, therefore anode-cathode distance can be reduced as far as possible, so as to significantly increase dust-collecting efficiency, especially
It is the dust-collecting efficiency to subparticle；Mutually collide, condense into the dust inside positive plate, grain is tied, among positive plate
Vertical channel final settlement is collected outward transport in ash bucket；Indivedual dust being attached on positive plate net cage wall, in deashing electrode
High frequency oscillation power is produced under alternating electromagnetism field action, is delivered to through insulating support on expanded metals tank wall and forms high frequency oscillation power by attachment
Dust rapping on pole plate is dropped.
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
It is small, the characteristics of in combination with gravitational dust collection and inertial dust collection, dust is pre-processed, further increases efficiency of dust collection,
Wide adaptation range, lightweight construction, there is higher cost performance and wide application prospect.
