Venturi scrubber series D Venturi Scrubbers are used to remove mist and particulate matter in the low micron to sub-micron range. To effectively remove sub-micron particles, the scrubbing liquid and particulate matter must collide under turbulent mixing conditions with sufficient energy to combine. High-energy turbulent contact is achieved by spraying water into the Venturi throat. The velocity of liquid and gas streams is accelerated in the throat where atomisation and collision of the water droplets with the particulate occurs. The water droplets agglomerate in the tail or diffuser section of the scrubber and must be passed through a separator unit to eliminate the relatively large entrained liquid particles. Entrained liquid droplets can be separated from the Venturi gas stream by either a dry Cyclone or shallow packed Bed. The Venturi scrubber features a high-pressure drop, which can range from 1.25 kPa to 17.5 kPa. Pressure drop generally increases with decreasing particulate size for a given collection efficiency. High-energy requirements usually limit Venturi scrubbers' applications to the collection sub-micron particulate matter. Venturi scrubbers are also used to a limited extent for the removal of noxious gases from air streams. Corrosion Resistant Construction from:
