Label declaration
Upper chamber 1, anode assembly 2, lower chamber 3, cathode line 4, pipe 41, needle thorn 42,
Antiswing device 5, high frequency electric source 6, water supply installation 7, drainpipe 8, chimney 9,
Hot air sweeping device 10.
Specific implementation mode
The utility model is further described in the following with reference to the drawings and specific embodiments.
As shown, a kind of simple wet electrostatic precipitation, white-smoke-removing device, including filled from top to bottom by upper chamber 1, anode
The dedusting region of the composition of 2, lower chamber 3 is set, lower chamber 3 and upper chamber 1 are made of Q235 steel plates, glass inner-lining scale anticorrosion, sun
Device 2 channel cross-section in pole selects regular hexagon, both ends that flange is arranged, is connect with upper chamber 1, lower chamber 3 by bolt, anode dress
2 are set using electroconductive frp, conduction PP or equivalent material.
Cathode line 4 is provided in anode assembly 2, the main body of cathode line 4 is pipe 41, and several columns needle is provided on pipe 41
Thorn 42, every needle pierce the center line of each side of hexagon on 42 face anode assemblies 2, improve field distribution uniformity, improve
Dedusting efficiency.42 arrangement ranges of needle thorn are more than 2 lower face of anode assembly, flue gas before entering anode assembly 2 with charged, one
It is adsorbed under electric field action into anode assembly 2, improves dedusting efficiency.The setting of cathode line 4 upper frame and lower frame it
Between, lower frame is connected with antiswing device 5, and upper frame is connect with high frequency electric source 6, and cathode line 4 is using 2205 two phase stainless steels or together
Equal materials.
Spray equipment is set in the anode assembly 2, spray equipment is supplied water by the water supply installation 7 for being arranged outside, lower chamber 3 with
Chimney 9 is connected to, and the bottom of lower chamber 3 is connected with drainpipe 8, spray equipment is also equipped in chimney 9.
Apply DC high voltage by high frequency electric source 6, makes cathode line 4 that corona discharge occur, generate a large amount of free electron
And cation, cation are attracted over and lose charge immediately, free electron and the anion that is formed immediately are then because by electric field
Driving to anode assembly 2 for power is moved, and when dust-contained airflow passes through electric field space, free electron, anion and dust collision are simultaneously attached
It thereon, Charged is driven by the effect of Coulomb force toward dust collecting electrode, by reaching anode assembly 2 after a certain period of time in the electric field
Surface releases the electrically charged and heavy collection of institute thereon, after the dust deposition to certain thickness on 2 surface of anode assembly, uses spray equipment
The methods of interval flushing is disposed, and is allowed to fall into lower chamber 3, is finally collected and is discharged by drainpipe 8.
Preferably, upper chamber 1 can also be connected to hot air sweeping device 10, hot air sweeping device 10 can generate hot wind pair
Dedusting area carries out hot-air blowing.
Exhaust gas volumn caused by changing flow direction due to elbow guiding air-flow on 3 import section of lower chamber is unevenly distributed,
Cause exhaust gas volumn that the huge increasing of local exhaust gas volumn, dust content is caused to increase after entering between anode assembly 2 and cathode terminal；Next draws
The serious unevenness of flue gas flow rate is played, for the big side of exhaust gas volumn since exhaust gas volumn increases, the raising of cigarette speed causes efficiency of dust collection to decline；And
Efficiency of dust collection is improved in the small side of smoke due to exhaust gas volumn is reduced, cigarette speed declines, but such as amount of bias conference because flue gas flow rate is too small
And influence drive from Charged to anode assembly 2 into, reduce efficiency of dust collection instead, therefore airflow-distribution board is set in lower chamber 3,
By increasing resistance, keep air flow method more uniform, airflow uniform distribution plate is PP materials porous plate or fiberglass Turbogrid plates.
The utility model can be effectively removed by above-mentioned dust removal process in equipment outlet wet flue gas by reasonable selection
85% and the above flue dust, it realizes minimum discharge environmental requirement, eliminates chimney 9 and export " emitting white cigarette " phenomenon.
Above are only specific embodiment of the utility model, at the same in all the utility model it is involved as " it is upper and lower, left,
The words such as right, centre " are only used as to refer to, not absolute limit, and all changes that unsubstantiality is carried out using the utility model should all
It falls into the category of infringing the protection scope of the present invention.
