Of the present utility model and cream wet scrubber is by tower body, top outlet inlet, bottom air inlet, spray equipment, packing layer and top vortex-flow and defrosting device form, and provide spray liquid by water circulating pump for spray equipment by self-contained water tank, but are structurally doing following improvement.
One, of the present utility model and cream wet scrubber changes the former spray equipment that places the bottom into and is positioned over glass filler layer top, realizes the cleaning to the glass filler layer of absorption lead dust and sulfuric acid mist.
Two, of the present utility modelly increase the many-sided ball packing layer with the cream wet scrubber on the top of spray equipment, to the pollutant second adsorption of not removing.
Three, of the present utility model and cream wet scrubber arranges the second spray equipment on the top of many-sided ball packing layer, to again flushing and the dissolving of many-sided ball packing layer and a small amount of rising pollutant of adsorption fouling thing.
Four, increase the alkali medicine-chest in the self-contained water tank of of the present utility model and cream wet scrubber, be communicated with water tank, for spray equipment provides alkaline spray liquid, realization is to chemical precipitation and the neutralization of pollutant, and in water tank, add medicament according to the testing result to spray liquid, make the spray liquid of the preparation in the water tank keep required alkalescence.
Five, of the present utility model and cream wet type sulfureous in flue gas acid and the lead content of discharging according to purifying column except the alkalescence value of the spray liquid of v dirt device determined.
Six, basic agent of the present utility model and the cream wet scrubber is NaOH.
The beneficial effects of the utility model are:
Of the present utility model and cream wet scrubber is scrubbed and the adsorption fouling thing more fully by increasing spray equipment and filler device.By in water tank, adding medicament, and adopt alkaline solution as spray liquid, improved the efficiency of dust collection to pollutant, protected environment, reduced pollution, guarantee qualified discharge.
