  • Pulsating flow scrubber attachment
    Patent number: 4609386
    Abstract: The efficiency of a spray-type scrubber in removing pollutants from gas flowing through the scrubber is improved by applying high frequency pulsations to the gas flow. The pulsations may be applied by a bladed rotor, the blades of which cut across the gas stream in a gas supply duct leading to the scrubber inlet, the rotor being harmonically tuned with a fan which draws the gas through the scrubber.
