Diamond powder pickling waste gas treatment device

Abstract: The utility model belongs to the field of superhard material production device, in particular to a diamond micro-powder pickling waste gas treatment device. The device comprises an alkali washing tower, an intake port of the alkali washing tower is connected with the pickling waste gas pipe, an intake port of the alkali washing tower is connected with the alkali liquid pipe, an outlet of the alkali washing tower is connected with the alkali liquid reflux pipe, the air outlet of the alkali washing tower is connected with the buffer settling barrel through the exhaust pipe, the exhaust pipe at the inlet of the buffer settling barrel is provided with an air shield, and the top of the buffer settling barrel is provided with several exhaust holes. The utility model has the advantages of simple structure, in which the acid waste gas produced by diamond micro-powder pickling is sprayed and neutralized by lye, while the air shield is combined with the buffer settling barrel to settle the neutralized waste gas again and remove impurities, and the waste gas after final treatment meets the requirements of environmental protection.
