Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
146 words
An apparatus for cleaning a dirty gas stream comprising: a housing having a flow through gas inlet and a flow through gas outlet with a scrubbing section disposed therebetween, said scrubbing section including a plurality of flow restrictive baffle members in parallel extending transversely of said housing, said baffle members having cross-sectional dimensional areas wherein one dimension is greater than the other dimension with pivot points eccentrically disposed a preselected distance from a longitudinal axis of said baffle members, adjacent baffle members having opposed pivot points, said baffle members including means to rotate adjacent baffle members in opposite directions, said means to rotate being connected to said pivot points whereby movement of said baffle members defines alternating converging and diverging sections between each pair of baffle members; and, means for spraying a scrubbing solution into said gas stream between said gas inlet and said scrubbing section.
