Waste gas treatment project of Yantai Jinao Environmental Protection Technology Co., Ltd.

This project is for the treatment of waste gas produced by the precious metal workshop of Yantai Jinao Environmental Protection Technology Co., Ltd., including pyro-smelting waste gas produced by converters, smelting furnaces, waste incinerators, etc., nitrogen oxide waste gas produced by nitric acid removal of impurities, and chlorination gold dissolution process. Chlorine and other acid waste gases.

Among them, the pyro-smelting exhaust gas produced by converters, smelting furnaces, garbage incinerators, etc. is first cooled by the surface cooler, then enters the cooling water tank for secondary cooling, and then enters the cyclone dust collector and pulse dust collector for dust removal treatment, and then enters the spray It is treated in the shower tower, and then discharged after being treated by electrostatic demisting.

Nitrogen oxide waste gas is produced by three 1500L nitric acid impurity removal kettles, which is treated by one-stage bubbling absorption + four-stage jet absorption + SDG adsorption + two-stage lye spraying, and the chlorine gas produced by chlorinated gold is produced by vacuum water ring + SDG adsorption + two-stage lye spray treatment, and then the flue gas is collected into the electric demisting system, and then discharged after dedusting and demisting.
