In the manufacturing processes of electronics factories, the acid and alkaline waste gases generated during the surface cleaning of electronic products can cause chronic or acute poisoning in humans. Therefore, environmental protection requirements dictate that electronics factories must treat their waste gases to meet standards before discharging them.
The main pollutants in acid and alkaline waste gases include nitric acid mist, hydrogen chloride, sulfuric acid mist, cyanide, chromic acid mist, and alkaline mist. Sources of waste gases: Acid and alkaline waste gases in electronics factories originate from PCB, semiconductor, electronics and optoelectronics, pickling and electroplating plants, electrolysis, battery electroplating, and other water-soluble air pollutants generated during production and processing.
So, how are acid and alkaline waste gases from electronics factories treated? Below is an introduction to acid and alkaline waste gas treatment solutions for electronics factories. Acid and Alkali Waste Gas Treatment Solution for Electronic Factories: The primary solution for treating acid and alkali waste gas in electronic factories utilizes a scrubbing tower system. This system employs a counter-current gas-liquid operation: a fan unit draws the collected waste gas into the scrubbing tower. Passing through the packing layer, the waste gas and absorbent liquid undergo thorough two-phase contact absorption and neutralization. After purification, the waste gas passes through a demister plate for dehydration and demisting before being discharged into the atmosphere by the fan. The absorbent liquid, pressurized by a pump at the bottom of the tower, is sprayed down from the top and returned to the bottom for reuse.
