Acid and alkali waste gas treatment systems are mainly used to treat acidic and alkaline harmful waste gases generated in industrial production. Washing and neutralizing This system achieves compliant emissions of purified waste gas. Centered on a spray tower, it utilizes a counter-current gas-liquid contact principle to neutralize acidic and alkaline pollutants in the waste gas with circulating reagents, removing harmful components before releasing clean gas into the atmosphere. The entire system is stable in operation, highly efficient, and suitable for industries such as chemical, electronics, electroplating, and laboratories, meeting both environmental protection and safety production requirements.
