Plate Scrubbers

Plate scrubbers are a highly efficient means of particulate removal, absorption of contaminants and gas cooling. In this type of scrubber (see above), the gas passes upwards through a number of small holes in one or more plates. Liquor enters on the top plate, flows across it and through a downcomer to the plate below. Intimate gas liquid contact is obtained as the gas bubbles through the liquid on the plate.

In the target plate design, a "target baffle" is located over each hole in the plate. As the gas passes through the perforations the dust particles impinge on the "targets" and they are collected by the liquor. For increased dust removal performance, a Venturi scrubber can be incorporated into a tray design in the form of a Venturi slot plate.
