Background technology
Along with country and the people are to the pay attention to day by day of environmental protection cause, the waste gas index being disposed to air is had higher requirement by national environmental standard. In common vehicle exhaust, waste incineration, plant gas often also exists a large amount of sour gas (such as sulfurous gas, NOx etc.), if wherein these sour gas can not get effective removing and arbitrarily discharge and can cause the phenomenons such as acid rain, impact ecology and HUMAN HEALTH.
To this, people often adopt washing plant spray to drench alkali water and are neutralized by the sour gas in waste gas, are easy to draw materials due to liming, with low cost, and have sterilization, are often preferably alkaline wash and use. But owing to liming is slightly soluble in water; traditional sprinkling equipment just simply adds the liming turbid solution made; its in and partially acidic gas after its effective concentration cannot be ensured; likely cause the insufficient just discharge of Sour gas disposal; and the gas slag that in turbid solution, undissolved calcium hydroxide obtains with neutralization with spray water outflow, particle mix; not only cause the waste of unslaked lime but also cause waste residue amount to increase, it is necessary to often clear up. Traditional washing plant in use flue gas to stop time in tower of short duration, it is possible to cause flue gas to be sufficiently purified. And alkali water and sour gas all have corrodibility, for this reason, traditional washing plant often adopts stainless steel to make, but the particulate matter such as dust in sour gas has stronger tack, inevitable device interior being scrubbed when cleaning equipment, waste time and energy and very easily draw the oxide film hindering body of stainless steel surface, so that the decline of corrosion protection of equipment ability.
Practical novel content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, it is provided that a kind of effective guarantee alkali water effective concentration makes sour gas by fully neutralization, the usage quantity effectively reducing liming raw material, waste residue amount, the corrosion-resistant novel flue gas soda lye wash device being convenient to again to clean.

2, the dividing plate hindering flue gas it is provided with so that the extended residence time of flue gas in soda lye wash device. Process more abundant.
3, employ have high acidproof, high alkaline-resisting and possess the polytetrafluorethylecoatings coatings of excellent not viscosity, it may also be useful to water blast gun just can light cleaning equipment, time saving and energy saving and improve work-ing life of equipment.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram;
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated. It is to be understood that specific embodiment described herein is only in order to explain the utility model, and it is not used in restriction the utility model.
Embodiment
As shown in Figure 1, soda lye wash device comprises liquid-storing box 1 and spray column 2, described liquid-storing box 1 is provided with two pieces of screen plates 11, liquid-storing box 1 is separated into inlet chest 12 by described screen plate 11 successively, dissolve case 13 and water tank 14, dissolve in case 13 and it is provided with turbine type agitator 131, dissolve case 13 casing and it is provided with viewing window 132 and dog-house 133, water tank 14 is provided with lift pump 141, the top of described spray column 2 is provided with the shower nozzle 21 of some individual intercommunications to each other, shower nozzle 21 is connected by the water side of inlet channel 3 with described lift pump 141, the envisaged underneath of described spray column 2 is up big and down small cone 22, the side of cone 22 is provided with water outlet 221 and emergent slag removing hole 222, described water outlet 221 is connected by the water-in 121 of water circulating pipe 4 with described inlet chest 12, the big end of cone 22 is provided with a cover plate 223, cover plate 223 is provided with conduction hole 224, the height of described conduction hole 224 apart from ground is lower than the height of described water-in 121 apart from ground.Also being provided with dividing plate 23 in spray column 2, spray column is divided into the first spray chamber 24 and the 2nd spray chamber 25 by dividing plate 23, leaves the gap can passed through for flue gas between the top of dividing plate 23 and the top of spray column 2.
The inwall of above-mentioned spray column and liquid-storing box is all coated with high acidproof, high alkaline-resisting and there is the polytetrafluorethylecoatings coatings of excellent not viscosity.
After starting outfit, turbine type agitator 131 can water in stirring and dissolving case 13 and lime particle to obtain saturated liming suspension liquid, water tank obtains the lime aqueous solution of clarification under the effect of screen plate 11, clarification lime aqueous solution enters in spray column 2 spouting from shower nozzle 21 with higher flow velocity through inlet channel 3 under the effect of lift pump 141, now pending flue gas enters from inlet mouth 26 needs row on the outflow direction first sprayed against shower nozzle 21 to discharge from air outlet 27 along spray direction under the effect of dividing plate 23 again, the residence time adding flue gas is with the reaction that fully contacts with spraying. spray water flows in cone 22 with the particle in gas, and major part particle precipitation is in the bottom of cone 22, and along with current flow to inlet chest 12 from water outlet 221, through filter plate 11 filtration, for dissolving, case 13 recycles part particle. in this process, owing to the height of conduction hole 224 apart from ground is lower than the height of described water-in 121 apart from ground, the water yield in cone 22 floods cover plate 223 all the time to prevent flue gas flows out from the conduction hole of cover plate 223. by the cleaned many waste residues of emergent slag removing hole 222, situation about dissolving in case 13 can be seen in real time by transparent viewing window 132, unslaked lime should be supplemented in time by dog-house 133 when liming suspension liquid becomes clear.
