Venturi and Cyclonic Scrubbers

Wet Scrubbers for Particulate Control

Venturi Scrubbers use high-energy impaction of liquid droplets to remove particulate from contaminated air streams. Water or other liquors are directed towards a constriction, or throat, where the atomized liquid scrubs the particulate from the air and transfers it to the scrubber liquid droplets. This type of technology is a part of the group of air pollution controls referred to as wet scrubbers. The amount of particulate removed from the air stream, or control efficiency, is based on several design elements, including pressure drop and contact time.

Venturi Scrubbers

  • Basic

    Diverse applications

  • Flooded Wall

    High dust loading or hygroscopic nature of the dust

  • Boiler

    Double-bladed throat damper for constant efficiency in fluctuating gas flows

  • Quencher

    High-temperature application

  • Impactor

    Multiple scrubbing techniques for dissolving tanks

  • Lime Slaker

    Mounted on top of lime shakers and uses the green slaker feed for scrubbing

  • Basic Oxygen Furnace

    Very high gas volumes (up to 1,000,000 acfm) and dust loadings

  • Type C-V

    Combines a Venturi with an enhanced cyclonic separator for large particulates and acid gas removal

  • Combination Particulate - Acid Gas Scrubbers

    Compact and low cost
