WET SCRUBBER - DESCRIPTION
A Wet Scrubber is an air pollution control device used to remove dust particles, fumes, and certain gaseous pollutants from industrial exhaust gases by bringing the contaminated gas into contact with a scrubbing liquid, usually water. It is widely used in industries to control air pollution and improve air quality.
WORKING PRINCIPLE
1. Dust-laden or polluted gas enters the wet scrubber.
2. Water or scrubbing liquid is sprayed through nozzles inside the scrubber.
3. The liquid comes into contact with the polluted gas and captures dust particles and other pollutants.
4. The contaminated liquid flows down and collects in the bottom tank or sump.
5. A mist eliminator removes water droplets from the cleaned gas.
6. The treated gas exits through the outlet and is discharged through the exhaust system.
