Abstract 1,089,715. Gas scrubber. WHIRLPOOL CORPORATION. Sept. 8, 1965 [Dec. 30, 1964], No. 38428/65. Heading B1R. In a gas scrubber the gas to be scrubbed is drawn by a fan 20 through a pipe 17 and bubbled through a body of liquid in a housing 12, the level of liquid in the housing being maintained by the supply of liquid thereto through pipe 27, valve 28 and an arrangement which discharges liquid into the pipe 17, the valve 28 being controlled by the pressure within the housing 12. The control means comprises a pipe 37 connected at its upper end to pressure responsive switches and dipping at its lower end into the liquid in the lousing so that the level of liquid therein affects the pressure in he pipe 37 and actuates he pressure responsive switches to open or close the valve 28 through a solenoid 29 :o supply or cut-off the supply of liquid to the nousing. The gas after bubbling through the liquid passes through a cylindrical screen 24 and is discharged through a cover 22. The lower end 13 of the housing 12 has an outlet 14 normally closed by a flap 15 held in its closing position by the subatmospheric pressure within the housing 12.
