Fume Scrubbers

Fume Scrubbers

Contaminants are removed by means of gas absorption, condensation, and impaction of particulates. These mechanisms take place within a packed bed for better interaction between the liquid and gas. Read Key Elements of Fume Scrubber Design & Maintenance for more information.

Wet Scrubber Variations:

• Mechanical scrubbers: Mechanized rotor produces fine water droplets in the air

• Orifice scrubbers: Velocity of process air is increased through an orifice, atomizing the water droplets and separating clean air from contaminants.

• Fiber-bed scrubbers: Wet-laden fiber mats collect mists as air passes through (small particulate removal only)

• Venturi scrubbers: Velocity of air or gas is increased through a venturi shape, forming fine water droplets and separating dust to form a slurry.

• Impingement-plate scrubber: Contact on perforated, horizontal plates between scrubbing liquid and process air flowing vertically in opposing directions creates a counter-current that captures contaminants.

• Spray nozzle scrubbers: Contaminated gas is horizontally accelerated through a powerful scrubbing liquid spray, the fine droplets of scrubbing liquid collide with gas and impinge with the particulate. Water soluble pollutants are absorbed by the spray droplets.
