Abstract
Abstract A gas scrubber in which the entering gas is driven through a turbulent bed of water and impinges on a submerged baffle to aspirate the gas and water upwardly through slots which impart a cyclonic flow to the water-entrained gas to effect a spinout of the solids which collect in the surge tank and the cleansed gas is discharged. The need for the usual pump for re-cycling water to provide scrubbing action is eliminated.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
113 words
In a gas scrubber comprising a tank, a disengaging section rising vertically above the tank and communicating therewith, and a downflow section within the disengaging section, the combination including an upflow section surrounding the downflow section and a scrubbing baffle, said upflow section having a lower end terminating below the lower end of said downflow section, said scrubbing baffle being mounted within said upflow section with at least a portion of said scrubbing baffle located below said lower end of said downflow section, said upflow section having an upper end and means at said upper end defining at least one spin slot for delivering gas from said upflow section to said disengaging section.
Claim 2
Dependent Claim
113 words
In a gas scrubber comprising a tank, a disengaging section rising vertically above the tank and communicating therewith, and a downflow section within the disengaging section, the combination including an upflow section surrounding the downflow section and a scrubbing baffle, said upflow section having a lower end terminating below the lower end of said downflow section, said scrubbing baffle being mounted within said upflow section with at least a portion of said scrubbing baffle located below said lower end of said downflow section, said upflow section having an upper end and means at said upper end defining at least one spin slot for delivering gas from said upflow section to said disengaging section.
Claim 3
Dependent Claim
45 words
A gas scrubber as claimed in claim 1, wherein said scrubbing baffle is substantially cone-shaped with the maximum cross-sectional dimension being less than the cross-sectional dimension of the upflow section and greater than the cross-sectional dimension of the downflow section at the lower end thereof.
Claim 4
Dependent Claim
34 words
A gas scrubber as claimed in claim 1, wherein said downflow section includes means defining a venturi throat proximate the lower end of said downflow section for accelerating gases travelling through said downflow section.
Claim 5
Dependent Claim
35 words
A gas scrubber as claimed in claim 1, wherein said tank includes a weir having an open end, the position of said open end in said tank determining the level of fluid in said tank.
Claim 6
Dependent Claim
57 words
A gas scrubber as claimed in claim 1, wherein said means defining said spin slot comprises an exterior wall of said downflow section, an interior wall of said upflow section and hood means cooperating between said interior and exterior walls for defining, with said walls, an exit opening for the exit of gas from said upflow section.
Claim 7
Dependent Claim
30 words
A gas scrubber as claimed in claim 5, wherein said exit opening is oriented to deliver gas therefrom in a direction tangential to the external surface of said downflow section.
Claim 8
Dependent Claim
52 words
A gas scrubber as claimed in claim 6, wherein said interior wall of said upflow section defining said spin slot is generally pie-shaped and said hood means includes an arcuate plate extending from the arcuate edge of said pie-shaped portion of said upflow section to said exterior wall of said downflow section.
