Venturi Scrubber Design Calculation Xls Upd

Venturi scrubbers are highly efficient mechanical separators used to remove fine particulate matter and gaseous contaminants from industrial exhaust streams. Operating on the principle of wet scrubbing, these systems utilize a high-velocity gas stream to atomize a scrubbing liquid into fine droplets. The resulting collision between dust particles and liquid droplets facilitates high-efficiency collection.

. By forcing gas through a narrow "throat" at high velocities (30 to 120 m/s), they create intense turbulence that atomizes scrubbing liquid into fine droplets, which then capture dust and fumes through inertial impaction. Key Design Parameters
