Apparatus For Cleansing Noxious Constituents From Gas Streams
US Patent:
4251485, Feb 17, 1981
Filed:
Mar 28, 1978
Appl. No.:
5/890988
Inventors:
John M. Schauer - Lockport IL
Dennis J. Schauer - Joliet IL
Dennis J. Schauer - Joliet IL
International Classification:
B01D 5334
US Classification:
422168
Abstract:
An apparatus for chemically altering and scrubbing the noxious constituents from foundry core manufacturing and arc welding operations comprising an upstanding closed container with a gas washing liquid disposed within the container to a predetermined level. A horizontal baffle is mounted stationarily within the container at an elevation spaced above the level of the gas washing liquid therein and spaced peripheral portions of the baffle are spaced inwardly of the opposing inner surface of the container. A gas drive pipe extends into the container, downwardly past the baffle, and opens downwardly in a central lower portion of the container, below the baffle and near the bottom of the liquid. The container includes a top cover and an outlet duct is provided which opens outwardly of the container through a central portion of the cover. The gases are pumped into the drive pipe to achieve a critical velocity at the exit of the drive pipe of about 2300-20,000 linear feet per minute.
