Expanded metals case（62）With cathode prickle wire（72）Net die opening be 100-200mm.
Refering to attached drawing 1, the cathode prickle wire and positive plate net cage interlaced arrangement of the utility model, the installation site of prickle wire
The recessed position arrangement of face positive plate net cage plate face, and keeps uniform arcing distance, between region form exhaust gases passes,
The charged probability of flue dust is enhanced, when the anode for cloudy prickle wire access high voltage power supply, positive plate net cage access high voltage power supply
During cathode, flue gas under the action of air flow method section, is evenly distributed to each exhaust gases passes through air inlet, into the powder of exhaust gases passes
After dirt cathode prickle is charged, and under the action of corona wind through positive plate mesh to positive plate inside drive into；Due to corona wind
And the effect of anode wooden partition online eye, the dust of low resistivity lose the phenomenon bounced and disturbed on anode, while anode
The back corona phenomenon of plate surface high resistivity dust has been entered inside dust chamber under the active force of corona wind, is effectively prevented from
The back corona phenomenon of anode plate surface, therefore anode-cathode distance can be reduced as far as possible, so that dust-collecting efficiency is significantly increased,
Particularly to the dust-collecting efficiency of subparticle；Mutually collide, agglomerate into the dust inside positive plate, grain is tied, through in positive plate
Between vertical channel final settlement be collected outward transport in ash bucket；Indivedual dust being attached on positive plate net cage wall, in deashing electricity
High frequency oscillation power is produced under the alternating electromagnetism field action of pole, being delivered to formation high frequency oscillation power on expanded metals tank wall through insulating support incites somebody to action
The dust rapping being attached on pole plate is dropped.
The utility model is organically acted on using corona wind and dust is confined to inside the positive plate of cavity, so as to reduce
Turbulence intensity in exhaust gases passes, improves dust collection effect；Dust size is smaller under dizzy wind action at the same time, its dust collecting performance
It is stronger；Secondly the utility model from dust specific resistance size restriction；Dust into dust chamber also has good fluid
Mechanics shielding action, can efficiently reduce loss of backflowing；It is efficient that the dust collection electric field of this configuration than conventional electric field flutters dirt, raises
Dirt loss is small, the characteristics of in combination with gravitational dust collection and inertial dust collection, dust is pre-processed, further increases dedusting
Efficiency, wide adaptation range, lightweight construction, has higher cost performance and wide application prospect.
