Description
Technical field
The present invention relates to a kind of novel close the pollutant that produces in the cream production process for the treatment of lead-acid accumulator and cream wet scrubber, it has optimized existing traditional and cream deduster.
Background technology
What people generally used in the past comprises tower body 16 with cream wet scrubber (seeing accompanying drawing 1), the air outlet 15 at tower body top, the air inlet 1 of tower body bottom, this air inlet links to each other with the paste mixing machine air outlet, air inlet top from bottom to top is disposed with spray equipment 12, glass marble packing layer 13, vortex-flow and defrosting device 14.The outlet of spray equipment 12 is connected with water tank 17 by spray pump 18.During work, the contamination gas that contains oxidation lead dust and sulfuric acid fog enters tower body 16 by the paste mixing machine outlet by air inlet 1, meanwhile, spray pump 18 is delivered to the spray liquid in the water tank 17 that spray equipment sprays in the tower downwards, up contamination gas and descending spray liquid cross and contact and adsorb dissolving, realize circulation along with liquid flows into the tower body bottom and flows into water tank by sewage draining exit thereupon.The contamination gas that does not absorb fully rises to packing layer 13, peels off by the glass marble adsorption in the packing layer and along with the glass marble of beating because of gas shock collides mutually.Flue gas after the processing is then discharged from air outlet 15.Because spray equipment and packing layer respectively only have one deck, can not fully dissolve and adsorption fouling gas, and packing layer places and causes on the spray equipment can't cleaning behind the adsorption fouling thing, the dirt on surface is accumulated, produce the obstruction of packing layer.The dry and hard lead dust in surface extracts through blower fan discharges, and is difficult to up to standard.This purifying column as spray liquid, adopts simple physics washing principle that contamination gas is processed with ordinary tap water in addition, can not satisfy 0.7mg/m
3Requirement.
Practical fresh content
Problem for the prior art existence, that designs that the absorption of a kind of Novel physical and chemical reaction combine closes the cream wet scrubber, adopt two sprays, the new structure of double-deck filler, and with alkaline solution as spray liquid, carry out chemical reaction with plumbous particulate in the plumbic acid contamination gas and sulfuric acid fog and reach and improve efficiency of dust collection, realize qualified discharge.
Technical scheme of the present invention is:
A kind of and cream wet scrubber, comprise tower body 8, dosing tank 9, water tank 10 and water circulating pump 11, top of tower has air outlet 7, tower body 8 bottoms are provided with air inlet 1, tower body 8 inside and are provided with successively many-sided ball packing layer 2, one deck spray equipment 3, many-sided ball filler 4, two layers of spray 5 and vortex-flow and defrosting device 6 from bottom to top, dosing tank 9 is arranged in the water tank 10 and communicates with it, and water tank 10 is connected with one deck spray equipment 3, two layers of spray 5 by water circulating pump 11.Used medicament in the dosing tank 9 is the NaOH of alkalescence.
Described air inlet 1 is to tower body 8 inner bendings.
Described vortex-flow and defrosting device 6 and air outlet 7 are communicated with.
Described one deck spray equipment 3 with are connected layer spray 5 and connect respectively water circulating pump 11.
Of the present invention and cream wet scrubber is by tower body, top outlet inlet, and the 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 invention 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 inventionly 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 invention 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 invention 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, the alkalescence value of the spray liquid of of the present invention and cream wet scrubber sulfureous in flue gas acid and the lead content of discharging according to purifying column determined.
Six, basic agent of the present invention and the cream wet scrubber is NaOH.
The invention has the beneficial effects as follows:
Of the present invention 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.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, a kind of and cream wet scrubber, comprise tower body 8, dosing tank 9, water tank 10 and water circulating pump 11, top of tower has air outlet 7, tower body 8 bottoms are provided with air inlet 1, tower body 8 inside and are provided with successively many-sided ball packing layer 2, one deck spray equipment 3, many-sided ball filler 4, two layers of spray 5 and vortex-flow and defrosting device 6 from bottom to top, dosing tank 9 is arranged in the water tank 10 and communicates with it, and water tank 10 is connected with one deck spray equipment 3, two layers of spray 5 by water circulating pump 11.Used medicament in the dosing tank 9 is the NaOH of alkalescence.
Air inlet 1 is to tower body 8 inner bendings.
Vortex-flow and defrosting device 6 and air outlet 7 are communicated with.
One deck spray equipment 3 with are connected layer spray 5 and connect respectively water circulating pump 11.
The principle of work of the present invention is: contain the pernicious gas of lead oxide and sulfuric acid mist under the promotion of blower fan power, enter the deduster spray liquid that contains alkali interior and under the pouring of top and contact, part lead dust and sulfuric acid fog are washed away dissolving and are flowed down with liquid.The pollutant of not eliminating rises to the glass marble packing layer, because being subjected to the glass marble of gas shock to seethe up and down collision, washed by the top spray equipment again, so that moistening glass marble surface forms gas-liquid contact mass transfer interface, pollutant is effectively absorbed mass transfer and chemical precipitation neutralization.In the remaining pollutant uphill process constantly by second layer many-sided ball packing layer and lower spray liquid absorption and the flushing dissolving of second layer spray equipment spray, again by the vortex-flow and defrosting device to the stopping of moisture content, so that it is clean and totally to enter the atmosphere Air.And absorption liquid is got back to water tank, through precipitation, impurity is wherein clarified, and is recycled by spray pump again.The water that consumes in the spray process then by special float valve type automatic water-replenishing device carry out automatic makeup to.According to the testing result to spray liquid, in water tank, add alkaline liquid, so that spray liquid keeps required alkalescence, keep 8-10 such as pH value.
With the main function of cream deduster be: adsorb mass transfer and contain the flushing of alkali spray liquid by multiple filling layers, reach the effect of the pollutant in the abundant elimination gas, when the pollutant that contains lead dust gas and acid mist gas enters in the tower body, with NaOH in the spray liquid following chemical reaction occurs.
