Abstract

The invention is concerned with the fathering method and the equipment for the flocking waste gas. It is: the first grade water spray tower reduces temperature of the flocking waste gas, removes the fluff and the ammonia gas, which can remove most of the fluff, NH3 and part of the organic contamination by the water circling spray process; the second oxidation tower processes oxidation to the low water-solubility substance in the waste gas by the first grade processing, which the ester substance with low solubility translates into the corresponding acid by the hypochlorous acid oxidation; the third grade alkali wash tower that the acid substance occurs neutralization reaction with lye in order to wipe off the substance. The invention is stable processing effect, not easy jam, and low operating cost.

Description

technical field [0001] The invention relates to the chemical purification technology of waste gas in environmental engineering, in particular to a treatment method and device for flocking waste gas. Background technique [0002] my country's electrostatic flocking industry emerged in the 1970s. After more than 30 years of development, electrostatic flocking production has begun to take shape, and the technology is becoming more and more mature. However, compared with the advanced level of electrostatic flocking in Europe and the United States, the structure of electrostatic flocking products in my country is still single and belongs to the middle and low grades. Most domestic and foreign markets have not been effectively developed. Therefore, the electrostatic flocking industry has broad development prospects. Electrostatic flocking enterprises emit a large amount of waste gas during the production process. The waste gas has the characteristics of large gas volume, high temp...
