Description of drawings
Fig. 1 is existing lead fume dirt chemical cleaning method tower structure sketch map;
Fig. 2 is the utility model lead fume dirt chemical cleaning method tower structure sketch map.
Among the figure, 1 blower fan, 2 water storage tanks, 3 tower bodies, 4 spray pumps, 5 exhaust ducts, 6 dosing pumps, 7 dosing tanks, 8 many-sided ball packing layers.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 2; The utility model lead fume dirt chemical cleaning method tower comprises tower body 3; The tower body inner bottom part is provided with water storage tank 2, top is provided with spray equipment; The pipeline that water storage tank 2 links to each other with spray equipment is provided with spray pump 4, and the tower body between water storage tank 2 and the spray equipment is provided with lead fume dirt input port, and this input port joins through pipeline and blower fan 1; In the tower body 3, the middle part between lead fume dirt input port and spray equipment also is provided with by many-sided ball and fills the packing layer 8 that forms; Also be provided with dosing mouth on the water storage tank 2, this dosing mouth links to each other with dosing pump 6, dosing tank 7 through pipeline successively, and dosing pump 6 is through adding the basic agent in the dosing tank 7 in the water storage tank 2 to, and the spray liquid in the water storage tank 2 is mixed with required pH value spray liquid.Also have on the water storage tank 2 and the identical automatic water-replenishing device (not shown) of existing lead fume dirt purifying column.
Lead content in the flue gas that the pH value lower limit of spray liquid is discharged according to purifying column is confirmed.Under the constant situation of other conditions, when PH arrives lower limit set value, then strengthen the deleading effect through the PH that improves spray liquid.
The utility model work principle is: the pernicious gas of leaded flue dust is under the promotion of blower fan power; The alkaline spray liquid that gets into the ejection of lead fume dirt purifying column and spray equipment collides each other; (adsorption layer wherein and deflection plate are the existing structure in the existing lead fume dirt purifying column through the processing of level Four such as spray section, packing layer, adsorption layer, deflection plate in the tower; Not shown), remove the harmful substance in the gas, clean air enters atmosphere.And absorption liquid is got back to the bottom water storage tank, in water storage tank, through deposition, makes impurity wherein be able to clarification, is recycled by spray pump again.The water that consumes in the spray process then carries out automatic supply by special float valve type automatic water-replenishing device.Dosing pump adds alkaline soup according to the testing result to spray liquid in the water storage tank in the trend tower body, so that spray liquid keeps required alkalescence, keep 8-10 like pH value.
The main function of lead fume dirt purifying column is: the packing layer in lead fume dirt gas gets into tower body, it is moving that the film that the gas in the gas phase and the alkaline solution of spray form on filler bead surface carries out line each other, and sufficient mass transfer absorption reaction takes place.We know lead fume dirt can with alkaline matter generation chemical reaction, reaction equation is:
Pb+NaOH+2H2O=NaPb(OH)3↓+H2↑
In alkaline solution, reaction generates plumbite and gas.Because gas-liquid is constantly reacted, thereby reaches good deleading effect.The dust-laden material of spray liquid and gas phase carries out catalytic exchange reaction, and the mixture of generation flows into the bottom water storage tank with spray liquid.
The difference of the maximum of this lead fume dirt purifying column and existing lead fume dirt purifying column is: existing purifying column is a water spray principle, and the water plumbous material of getting along well reacts, and only relies on the physical impacts control of dust.And the utility model is the chemical reaction that utilizes material, produces the third material control of dust.Therefore improved clean-up effect.
Spray liquid in the purifying column is an alkaline solution, adopts the mode that recycles.Both economical, convenient again.Only need regularly discharge of wastewater to be handled to sewage plant to get final product.
Embodiment recited above only describes the preferred implementation of the utility model, is not that design and scope to the utility model limits.Do not breaking away under the design concept prerequisite of the utility model, common engineers and technicians make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model.
