Water droplet, flows in clear water, and sour gas enters into second container through the first demister 117 from the exhaust outlet 114 of the first container 11
In 12, by the clear water in second container 12 further by acid gas clean, acidic gas concentration is reduced, as follows circulated, it is acid
Gas is fully contacted with the clear water in second container 12~the 4th container 14, and clear water continuously carries out comprehensive clear to sour gas
Wash, can be by the concentration of sour gas reduction by 50 or so percent；Then, sour gas and the 5th container 15 and the 6th container
Akaline liquid in 16 is fully contacted, and carries out neutralization reaction, makes the concentration reduction by 80 or so percent of sour gas；Followed by
Sour gas is fully contacted with the clear water in the container 20 of the 7th container the 17~the tenth, extends process time, and clear water continues to acidity
Gas carries out comprehensive cleaning, makes the concentration reduction by 98 or so percent of sour gas, finally by the 11st container 21
Molecular sieve 1220 and active carbon layer 123 absorb remaining a small amount of sour gas and taste removal, finally by the gas outlet of aspiration pump 23
Discharge.
A kind of dense acid mist purifying device that the present invention is provided, is in series with 11 containers, by aspiration pump in its cabinet 1
During concentrated acid mist to dissolve in 23 generation high velocity airs clear water or akaline liquid in 11 containers successively, concentrated acid mist first passes around the
The filtering and shunting of the first current equalizer 115 and the second current equalizer 116 in the container 14 of one container the 11~the 4th, by concentrated acid mist
Pollutant is dissolved in clear water, clear water can with concentrated acid mist carry out it is comprehensive contact, process time is extended in clear water, can be effective
Particulate matter in removal concentrated acid mist simultaneously makes Water-soluble Organic Substances be dissolved in water, and by the first demister 117 by the acid of preliminary purification
Property gas is separated with mist, and the full bath from the akaline liquid in the 5th container 15 and the 6th container 16 passes through sour gas again, by
The first current equalizer 115 and the second current equalizer 116 in 5th container 15 and the 6th container 16 are shunted, and drastically increase sour gas
Body and akaline liquid contact area, sour gas are fully contacted and reacted with akaline liquid, improve the absorption of akaline liquid
Efficiency, realizes dilution, neutralizes sour gas and reduce the purpose of acidic gas concentration, then by the container of the 7th container the 17~the tenth
The first current equalizer 115 and the second current equalizer 116 in 20 are shunted, the clear water of sour gas and the container 20 of the 7th container the 17~the tenth
Comprehensive contact is carried out, acid mist gas is further purified, finally by the molecular sieve 1220 and activated carbon in the 11st container 21
Layer 123 absorbs and taste removal remaining trace acidic gas, realizes and concentrated acid mist is thoroughly purified, and makes the rear sour gas of purification
Reach the standard of country's discharge.
