2and NO
xdeng discharge, so its discharge process and emission comparison of ingredients complexity.
As Chinese Patent Application No. 201320222088.2 discloses a kind of acid fog recovery device, comprise retort, the connection absorption tower, upper end of described retort, the sidewall on described absorption tower is by pipeline communication retort, the top on described absorption tower is provided with blast pipe, in described absorption tower, is provided with packed layer, and described packed layer is provided with multiple micropores, the top of described packed layer is provided with shower, and described shower is communicated with NaOH solution tank NaOH.Although above-mentioned patent structure is simple, its purification efficiency is not high.
Utility model content
The purpose of this utility model is to provide a kind of acid mist purifying retracting device, has solved the problem that existing acid mist purifying retracting device purifies, organic efficiency is not high, and simple in structure.
The utility model solves the technical scheme that its technical problem adopts: a kind of acid mist purifying retracting device, comprise acid mist purifying tower, be arranged on the air inlet of acid mist purifying tower side wall below, be arranged on the discharge duct of acid mist purifying tower top, the inside of acid mist purifying tower is furnished with the first shower and the second shower up and down, and the first shower and the second shower inside are provided with condensate liquid; Between described the first shower and the second shower, be also provided with screen pack; The bottom of described acid mist purifying tower is provided with accumulator tank, and this accumulator tank is connected with acid mist purifying tower by pipeline.Preferably, accumulator tank inside is provided with condensate liquid, is provided with for condensate liquid is pumped to the circulating pump of the first shower on its sidewall.
Further, condensate liquid is deionized water, is equiped with deionized water pipeline on the second shower.
Further, screen pack is polyethylene silk screen demister, and be furnished with up and down two groups between the first shower and the second shower, every networking layer is 80 layers, purify by continuous filtration, only a few acid mist is attached on polyethylene silk screen demister, and by deionized water, demister acid mist is flowed into accumulator tank, acid mist purifying efficiency reaches more than 99.9%.
The beneficial effects of the utility model: the acid mist that enters acid mist purifying tower is carried out to a condensation by the first shower, part acid mist is attached on polyethylene silk screen demister after net filtration after filtration, a small amount of acid mist carries out time condensation through the second shower, make it to deliver to accumulator tank by pipeline, and recycle by circulating pump, in the time that reaching a certain amount of, the acid mist concentration in accumulator tank added retracting device to be used.
The airspeed excessively of acid mist waste gas reality is 1.00～2.50m
3/ s, intake air temperature is lower than 60 DEG C, and entering the shower water that is condensed before screen pack, to impact the acid mist temperature of getting off be 35 DEG C, and under cryogenic conditions, acid mist is impacted condensation and is dropped to accumulator tank, and fogdrop diameter is less than 0.04nm, and maximum vapor/liquid ratio area is 1:2400.
The first shower, the second shower adopt PVC to make, and the continuous Sprayer Circulation of titanium pump high pressure for condensate liquid has intensity height and corrosion resistant feature.
Adopt two groups of polyethylene silk screen demisters arranging continuously, every networking layer is 80 layers, purify by continuous filtration, only a few acid mist is attached on polyethylene silk screen demister, and by deionized water, the acid mist on wire mesh demister is poured to accumulator tank, acid mist purifying efficiency reaches more than 99.9%, and 99% acid mist of absorption is dissolved in and in deionized water, all returns to use, outer row.
The utility model acid mist emission concentration after treatment is 8.7 × 10
-4mg/m
3, the requirement lower than country about newly-built enterprise Air Pollutant Emission limit value, can accomplish stably reaching standard discharge.This treatment process treatment effeciency is high, and operating cost is very low, safe and reliable.
