What is a wet curtain wall?

A wet curtain wall is an environmentally friendly device used for air purification and exhaust gas treatment. It primarily removes harmful substances through contact between a liquid and polluted gases. It works by passing industrial exhaust or polluted air through a scrubbing zone filled with water mist or a chemical solution. Pollutants such as dust, acidic substances, and toxic gases in the air are captured by the liquid or undergo chemical reactions, achieving a purification effect.

Wet curtain walls are widely used in industries such as the chemical industry, power generation, metallurgy, and waste incineration. They can effectively treat acidic or alkaline gases such as sulfur dioxide, hydrogen chloride, and ammonia, while also filtering out some particulate matter and volatile organic compounds. Compared to dry dust removal equipment, wet curtain walls offer the advantage of being able to treat multiple pollutants simultaneously, making them particularly suitable for exhaust gas environments with high temperatures, high humidity, or high corrosiveness. However, wet curtain walls generate wastewater during operation, which requires further treatment, and their effectiveness in purifying certain gases that are poorly soluble in water is limited. They are typically used in conjunction with other purification technologies to achieve more comprehensive exhaust gas treatment goals.
