Technical field
The present invention relates to chemical emission process field, especially relate to a kind of chemical emission treatment facility.
Background technology
Chemical emission refers to the poisonous and hazardous gas of being discharged by chemical plant in Chemical Manufacture.It is a lot of that chemical emission often contains pollutant kind, and physics and chemistry character is complicated, and toxicity is also not quite similar, serious environment pollution and affect health.The chemical emission composition difference that different Chemical Manufacture industries produce is very large.As mainly contained chlorine, hydrogen chloride, vinyl chloride, mercury, acetylene etc. in the waste gas of chlor-alkali industry generation, in the waste gas that Nitrogenous Fertilizer Industry produces, mainly contain nitrogen oxide, carbamide dust, carbon monoxide, ammonia, sulfur dioxide, methane etc.At present, at waste gas treatment equipment, be all air inlet pipe to be directly passed into liquid level with the harmful substance in lower absorption waste gas, the gas passing into due to flue gas leading normally enters with bubble form, the pernicious gas of bubble surface could be by liquid absorption, the pernicious gas of bubble inside is not absorbed direct discharge, and waste gas only reacts with flue gas leading liquid around, flue gas leading liquid absorption pernicious gas is around saturated no longer to be absorbed, the object that absorbs pernicious gas will do not reached like this, at present, the measure adopting adds agitating device exactly, make liquid flow, guarantee that flue gas leading has enough reaction liquids around, yet this mode not only needs to waste electric power, and can make the gas being dissolved in liquid again separate out, do not reach the object that absorbs pernicious gas yet.
Summary of the invention
Technical problem to be solved by this invention is to provide and does not a kind ofly need agitating device and can guarantee the chemical emission treatment facility that pernicious gas fully absorbs.
The present invention solves the technical scheme that its technical problem takes: a kind of chemical emission treatment facility, comprise the first airtight water tank, the second water tank and chemical processing tank, the first outlet of the first water tank is connected with the chemical treatment import of chemical processing tank, the chemical treatment outlet of chemical processing tank is connected with the second import of the second water tank, the second outlet of the second water tank is communicated with the air inlet of exhaust gas treating tower, exhaust gas treating tower inside is provided with spraying layer successively, dehydration layer and active carbon layer, the first import of the first described water tank, chemical treatment import and the second import all extend into below liquid level, the first described water tank, in the second water tank and chemical processing tank, be provided with a dividing plate, dividing plate is positioned at below liquid level, described dividing plate is provided with the aperture for bubble is cut apart of array arrangement, described the first import, chemical treatment import and the second import are all inserted below dividing plate.
Further, in order to guarantee waste gas form reactive absorption with minute bubbles in liquid, the first described import, chemical treatment import and the second import department are provided with cellular gas outlet.
Further, for the EGT of the first import department is reduced, the first described import department is provided with a heat exchanger.
Further, in order to make the water under spray state recycle, described exhaust-gas treatment tower bottom is provided with storage tank, and the delivery port of storage tank connects filtration system, by water pump, is connected with the shower in spraying layer.
Further, for the content of the waste gas oxynitrides that can guarantee to discharge reduces, between described dehydration layer and active carbon layer, be provided with SCR catalytic unit.
Further, in order to reduce the speed of waste gas in entering exhaust gas treating tower, described exhaust gas treating tower is cylindric, and its air inlet is opened in the tangential direction of exhaust gas treating tower cylinder.
The invention has the beneficial effects as follows: after having adopted said structure, by being with foraminate dividing plate air pocket can be divided into minute bubbles, carry out reactive absorption, make gas at the enough abundant reactive absorption of internal energy of liquid, and do not need to stir and bubble larger area can be distributed; Use cellular gas outlet when gas enters liquid, first to cut apart, cutting apart afterwards by dividing plate, what bubble can be cut apart is less, is more conducive to liquid absorption pernicious gas.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
A kind of chemical emission treatment facility as shown in Figure 1, comprise the first airtight water tank 5, the second water tank 9 and chemical processing tank 7, the first outlet 1 of the first water tank 5 is connected with the chemical treatment import 6 of chemical processing tank 7, the chemical treatment outlet 8 of chemical processing tank 7 is connected with the second import 10 of the second water tank 9, the second outlet 11 of the second water tank 9 is communicated with the air inlet 13 of exhaust gas treating tower, exhaust gas treating tower inside is provided with spraying layer 12 successively, dehydration layer 18 and active carbon layer 20, the first import 1 of the first described water tank 5, chemical treatment import 6 and the second import 10 all extend into below liquid level, the first described water tank 5, in the second water tank 9 and chemical processing tank 7, be provided with a dividing plate 2, dividing plate 2 is positioned at below liquid level, described dividing plate 2 is provided with the aperture for bubble is cut apart of array arrangement, described the first import 1, chemical treatment import 6 and the second import 10 are all inserted dividing plate below 2, the first described import 1, chemical treatment import 6 and the second import 10 places are provided with cellular gas outlet 3.
Because waste gas out from equipment is with very high heat, so directly be passed into that the first water tank 5 is interior will cause the waste of heat, so be provided with a heat exchanger at the first import 1 place, to waste gas, lower the temperature, and the heat of exchange can be used to other place, in waste gas after cooling, some gases directly condense into liquid, reduce the burden of follow-up absorption.
