Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 340 words
A gas-washer comprising: a. a tubular vessel having a generally vertical axis; b. means causing said gas to flow into and through said tubular vessel; c. a rotatable shaft within said tubular vessel having a generally vertical axis and means for rotating said shaft; d. a first disc fixed to said shaft in generally perpendicular relation thereto and rotatable therewith and means for flowing a first liquid onto the top surface of said first disc so that said first liquid is thrown off the outer periphery of said disc and onto the wall of said tubular vessel in a sheet of continuous surface extending from the outer periphery of said disc to the wall of said vessel; e. a second disc fixed to said shaft in generally perpendicular relation thereto and rotatable therewith and means for flowing a second liquid onto the top surface of said second disc so that said second liquid is thrown off the outer periphery of said disc and onto the wall of said tubular vessel in a sheet of continuous surface extending from the outer periphery of said disc to the wall of said vessel; f. separator means interposed between said first disc and said second disc and extending across said tubular vessel to divide said tubular vessel into two chambers, said separator means being previous to said gas and impervious to both said first liquid and said second liquid in operation; said separator means comprising an annular disc surrounding said rotatable shaft with its outer periphery sealed liquid-tight to the inner wall of said tubular vessel and a flange about its inner periphery, and a honeycomb member filling the center of said annular disc and surrounding said rotatable shaft, whereby liquid entrained in said gas in passing from one of said chambers of said tubular vessel to the other is condensed on said honeycomb and liquid in said other chamber is prevented from flowing into said one of said chambers; and g. first and second liquid outlet means on opposite sides of said separator.
Claim 2
Dependent Claim 340 words
A gas-washer comprising: a. a tubular vessel having a generally vertical axis; b. means causing said gas to flow into and through said tubular vessel; c. a rotatable shaft within said tubular vessel having a generally vertical axis and means for rotating said shaft; d. a first disc fixed to said shaft in generally perpendicular relation thereto and rotatable therewith and means for flowing a first liquid onto the top surface of said first disc so that said first liquid is thrown off the outer periphery of said disc and onto the wall of said tubular vessel in a sheet of continuous surface extending from the outer periphery of said disc to the wall of said vessel; e. a second disc fixed to said shaft in generally perpendicular relation thereto and rotatable therewith and means for flowing a second liquid onto the top surface of said second disc so that said second liquid is thrown off the outer periphery of said disc and onto the wall of said tubular vessel in a sheet of continuous surface extending from the outer periphery of said disc to the wall of said vessel; f. separator means interposed between said first disc and said second disc and extending across said tubular vessel to divide said tubular vessel into two chambers, said separator means being previous to said gas and impervious to both said first liquid and said second liquid in operation; said separator means comprising an annular disc surrounding said rotatable shaft with its outer periphery sealed liquid-tight to the inner wall of said tubular vessel and a flange about its inner periphery, and a honeycomb member filling the center of said annular disc and surrounding said rotatable shaft, whereby liquid entrained in said gas in passing from one of said chambers of said tubular vessel to the other is condensed on said honeycomb and liquid in said other chamber is prevented from flowing into said one of said chambers; and g. first and second liquid outlet means on opposite sides of said separator.
