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.

Venturi Scrubber Design Calculation Spreadsheet (UPD) The is an engineering spreadsheet tool used to dimension wet scrubbers, calculate gas differential pressure drop, and predict particulate collection efficiency. Venturi scrubbers are highly efficient mechanical collectors that use a liquid stream to capture fine particulate matter and hazardous air pollutants from industrial exhaust gas streams. 1.

Sequential rows utilizing the equations listed above. Use structured formulas rather than hardcoded values.
A Venturi scrubber is a type of air pollution control device used to remove particulate matter and gases from industrial exhaust streams. The design of a Venturi scrubber requires careful calculation to ensure efficient operation and optimal performance. This write-up provides an overview of the design calculation for a Venturi scrubber using an XLS (Excel) spreadsheet.
Warning alerts if the throat velocity is too low (poor collection) or too high (excessive re-entrainment). Dt=4⋅Atπcap D sub t equals the square root
Many Excel tools use for efficiency and pressure drop.
