2100% discharging.Flying dust is to produce mobile the polluting of 2 suspensions of flying dust in formula static device ash disposal rapping.
At present domestic and international known gas cleaning separation equipment: ash disposal is based on the ash disposal of dry type static device.Ash disposal efficient 98%, moisture film tower are time ash disposal efficient 85～90%.Removing liquid is mechanical demister, demist 50%.So at present world's atmosphere pollute and mainly be " 5 microns grits and＜6-8 micron acidic liquid mist pearl-acid rain.
The world does not also have a kind ofly can remove the separating equipment for purification that contains solid dirt, liquid mist pearl synchronously.
The world does not also have a kind of deduster purification separation to go out the " separating equipment for purification of 1 micron grit
Also there is not a kind of deduster, efficiency of dust collection＞99.9％。It is very big that efficiency of dust collection reaches 99% dedusting investment.Take up an area of very big.
The unrenewable dirt of various dedusters, granularity＜10 micron.This is China's atmosphere pollution major pollutants.
To the ash disposal of dry type static device, to eliminate flying dust and pollute, the ash disposal of static device can not rapping.
Desulfurization produces CaHSO
3.H
2O aqueous solution mist pearl, mechanical demister can not full scale clearance CaHSO
3.H
2O aqueous solution mist pearl.So can not use mechanical demister, remove CaHSO
3.H

So also do not have a kind of not only dedusting at present both at home and abroad but also remove CaHSO
3.H
2The equipment of O aqueous solution mist pearl.
The utility model; The purpose of wet electrostatic device; A kind of equipment that solid dirt in the multiphase flow flue gas and liquid mist pearl separated in synchronization are come out is provided.
Be synchronously with dirt in the flue gas and SO
2The CaHSO that generates
3.H
2O aqueous solution mist pearl separated in synchronization is come out.Reach efficiency of dust collection＞99.9%.Remove liquid efficient＞99%.
Be patent of invention; Flue-gas dust-removing and desulfurization, the supporting special equipment of desulfurating high-purity gypsum making technology.--the wet electrostatic device.
For achieving the above object.This patent embodiment:
The liquid mist pearl, the liquid pearl and the grit that contain solid dirt are adsorbed by pole plate (2), and absorption pools stream, and is past dirty along pole plate.Dash with the flushing water on the pole plate again, keep the cleaning of absorption pole plate.Operation is normal.The pollution that vaporific flue gas and electrostatic precipitation rapping suspend and flow and cause for 2 times behind the elimination water film dedusting, ash disposal efficient＞99.9%. removes liquid efficient＞99%.Eliminate vaporific flue gas, CaHSO
3.H
2The pollution that O aqueous solution mist pearl (various mist pearl) is caused, efficient reaches 99%
Low temperature contains the flue gas of solid grit and mist pearl, and grit and mist integument pole plate (2) absorption dash with the flushing water on the pole plate.Eliminate the pollution of dirt, efficiency of dust collection＞99.9%.
The long M rice of wet electrostatic device (NXmm), wide S rice, high H rice.
Absorption pole plate distance X mm.Long＞3 meters of absorption pole plate.
On the absorption pole plate, press the long S rice of dress φ Bmm water pipe.Female pipe connects with supplying water.
Below φ Bmm water pipe, φ 3mm hole is bored on the 25mm both sides at interval.
On the φ Bmm water pipe with the guard shield cover on.Flow to the pole plate two sides along guard shield after making φ Bmm water pipe ejection water bump guard shield,
Adsorbate on pole plate two sides flushing pole plate, flushing thing and water break away from pole plate along pole plate stream.
Discharge electrode is the Lmm1 root at interval, and discharge electrode is long " 3 meters.
Discharge electrode is installed on the 150mm channel-section steel.Equidistant with two-plate, parallel.
The long S rice of 150mm channel-section steel N root, (S+1) mm is long 2.
(S+1) the long 2 150mm channel-section steels of mm are fixed on the insulated case (8).
Insulated case (8) is fixed on quiet electric appliance box (1), insulated case (8) and quiet electric appliance box (1) insulation.
The architectural feature of this wet electrostatic device is:
The structure of wet electrostatic device is vertical.Comprise; Quiet electric appliance box (1),
Absorption pole plate (2) is fixed on quiet electric appliance box (1) upper and lower fixing plate.
Absorption pole plate (2) is pressed dress at electric field with the equidistant parallel type
Discharge electrode (3) is fixed on the discharge electrode frame (6),
Discharge electrode (3) can be pressed dress with netted or linear pattern at electric field
Discharge electrode frame (6) is fixed on the insulated case (8)
