Scrubbers: The Major Types of Industrial Scrubbers

Wet Scrubbers, Dry Scrubbers, and Electrostatic Precipitators. Scrubbers are air pollution control devices that use liquid to remove particulate matter or gases from an industrial exhaust or flue gas stream. This atomized liquid (typically water) entrains particles and pollutant gases in order to effectively wash them out of the gas flow.

Condensing scrubbers | Babcock & Wilcox Vølund AB

Flue gas condensation; CONDENSING SCRUBBERS; Condensing scrubbers can be made as stand-alone units or for integration in our multi-stage scrubber concept. In their standard design they are made from GRP (glass reinforced plastic). They have the great advantage of not suffering corrosion in ways that condensers made from metal do, and they are ...

Air Pollution Control Technology Fact Sheet - US EPA

In a wet scrubber system, flue gas is ducted to a spray tower where an aqueous slurry of sorbent is injected into the flue gas. To provide good contac t between the waste gas and sorbent, the nozzles and injection locations are designed to optimize the size and density of slurry droplet s formed by the system.

Dry Scrubbers. Dry scrubbing systems consist of two main sections or devices: the scrubber and the scrubber media. Dry scrubbers spray very fine absorbents into a vessel where they combine with flue gases. The resulting sorbent is captured by the scrubber media, called a baghouse. Different scrubber media remove pollutants in multiple ways,...
