Description

technical field [0001] The invention relates to electroplating equipment, in particular to a recycling and processing device for chrome-plating waste gas in electroplating. Background technique [0002] At present, the electroplating industry occupies an important position in my country's industry, mainly chrome plating, which is used in various chrome plating industries, such as: engineering continuation, coal mining machinery and piston rings. During the electroplating process, a large amount of Heavy metal chrome-plating waste gas, if it is not treated in time and discharged into the atmosphere, will cause serious environmental pollution. In recent years, most of the treatment of chrome-plating waste gas is to concentrate and utilize the heavy metals in the electroplating waste gas. The actual utilization rate of acid is 20%, and 30% of chromic acid is consumed by volatilization in exhaust gas, resulting in a lot of waste. Contents of the invention [0003] The technical...
