[0002] A large amount of acid mist of sulfuric acid-copper sulfate solution is formed in the production process of electrolytic copper foil, most of which is from the electrode surface bubble precipitation in the electrodeposition process, and part of which is from the volatilization of the electrolytic production liquid. Acid mist has many adverse effects, such as acid mist falling on the surface of copper foil, which can accelerate the oxidation of copper foil and form black oxidation points. Acid mist entering the air can cause harm to the human body and the environment. The exhaust device is one of the indispensable equipment in the production process of electrolytic copper foil, which is mainly used to remove acid mist in the production process. However, the acid mist contains copper sulfate components, and the acid mist falls in the exhaust duct, and the copper sulfate crystals are formed by drying and precipitation. After a long time of operation, the crystals in the exhaust duct will continue to accumulate, resulting in thicker and thicker, which seriously affects the rate of acid mist exhaust, and if not cleaned in time, the exhaust pipeline may be blocked. In view of the problem of pipeline crystallization, manual cleaning method is used for control, and a large amount of pure water is used for pipeline cleaning, but the operation is extremely tedious, and it is difficult to accurately judge the timing of cleaning, which greatly increases the difficulty of acid mist control.
