Abstract
Abstract A gas scrubber is disclosed and includes a housing which contains a water bath and a pair of spaced apart baffle means which extend below the level of the water bath at their lower ends and divide the interior of the housing above the water bath into a receiving zone, a turbulent zone and a discharge zone. A third baffle means extends from the bottom of the housing and ends above the level of the water bath between the pair of baffle means. The arrangement of the housing and baffle means in connection with the water bath is such that gas containing entrained solids is passed through the scrubber in a tortuous path in and out of the water bath resulting in removal of solids entrained in the gas and a discharge of substantially clean gas.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
Gas scrubber for removing solids entrained in a stream of gas comprising a housing having a bottom, side walls and a top and containing a water bath, a pair of spaced apart baffle means extending down from the top of the housing to below the level of the water bath at their lower ends and dividing the interior of said housing above the water bath into a receiving zone, a turbulent zone and a discharge zone, and third baffle means extending from the bottom of the housing and inclined at an angle of from 20*-40* from the vertical toward said discharge zone and ending just above the level of the water bath at a point approximately midway between said pair of baffle means, said inclined baffle means directing entry of gas passing through said water bath from said receiving zone into said turbulent zone, said turbulent zone existing between said pair of baffle means and said housing and promoting further wetting of entrained solids causing them to be retained in said water bath, and suction means adapted to draw gas in a tortuous path in and out of said water bath and through said zones.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
248 words
Gas scrubber for removing solids entrained in a stream of gas comprising a housing having a bottom, side walls and a top and containing a water bath, a pair of spaced apart baffle means extending down from the top of the housing to just below the level of the water bath at their lower ends and dividing the interior of said housing above the water bath into a receiving zone, a turbulent zone and a discharge zone, third baffle means inclined toward said discharge zone and extending from the bottom of the housing and ending just above the level of the water between said pair of baffles, a gas inlet in the receiving zone and a gas outlet in the discharge zone, said inlet and said outlet being above the water bath, water spray means associated with the gas inlet for wetting solids entrained in gas entering the receiving zone and for maintaining said water bath at a predetermined level in conjunction with overflow drain means in said discharge zone, suction means associated with the gas outlet adapted to draw gas in a tortuous path in and out of said water bath and through said zones, said third baffle means directinG entry of gas passing through said water bath from said receiving zone into said turbulent zone, said turbulent zone existing between said pair of spaced apart baffle means and said housing and promoting further wetting of entrained solids causing them to be retained in said water bath.
