Net cage（62）With cathode prickle wire（72）Net interpolar away from for 100-200mm.
Refering to attached drawing 1, cathode prickle wire of the invention and anode plate net cage interlaced arrangement, the installation site face of prickle wire
The recessed position arrangement of anode 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 cathode of high voltage power supply is accessed for cloudy prickle wire, anode plate net cage accesses the anode of high voltage power supply
When, flue gas under the action 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 under the action of corona wind through anode plate mesh to anode plate inside drive into；Due to corona wind and sun
The effect of mesh on pole plate wall, the dust of low resistivity is lost bounce and disturb on anode the phenomenon that, while anode plate table
The back corona phenomenon of face high resistivity dust has been entered under the active force of corona wind inside dust chamber, efficiently avoids sun
The back corona phenomenon of polar board surface, therefore interpolar 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；It mutually collides, agglomerates into the dust inside anode plate, grain is tied, among anode plate
Vertical channel final settlement is collected outward transport in ash bucket；Indivedual dust being attached on anode plate net cage wall, in deashing electrode
High frequency oscillation power is generated under alternating electromagnetism field action, is transferred to through insulating support on expanded metals tank wall and forms high frequency oscillation power by attachment
Dust rapping on pole plate is dropped.
