Process introduction.

The company signed a contract with Xinjiang Wuxin Copper Co., Ltd. for gold and silver refining treatment, each batch can refine 10-15kg of palladium, using glass material reaction vessel and liquid storage tank, the whole reaction process is transparent and visible, easy to clean, no backlog, the reaction vessel and filtration device are using real air conditioning liquid, easy to operate, the reaction air cabinet is designed with transparent sliding door, the air cabinet is designed with fume deflector, which can produce The exhaust gas can be completely extracted.

The exhaust gases to be treated are nitrogen oxide exhaust gas from the dissolution of palladium aqua regia and alkaline exhaust gas from the palladium refining process. The nitrogen oxide exhaust gas is treated by two-stage bubble absorption + four-stage jet absorption + one-stage alkaline spraying, and the alkaline exhaust gas is treated by two-stage acid spraying.
