The waste gas in electroplating plants mainly comes from acid mist and alkaline gases volatilized during acid-base soaking. This waste gas is highly corrosive and poses significant hazards to the human body. Electroplating plants typically emit gases such as nitric acid, sulfuric acid, and hydrofluoric acid, which are treated using an acid washing tower. The process involves drawing the waste gas into the tower for neutralization treatment, followed by discharge through an exhaust fan to meet the emission standards.
