Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
147 words
Gas purification apparatus comprising housing means having inlet and outlet means, means for passing the gas through said housing means, a separating wall located in said housing means between said inlet means and said outlet means, and means positioned in said housing means upstream of said wall for spraying wash liquid into said gas stream, said separating wall having at least one first pair of slots converging in the direction of flow and opening into a common zone and at least one other slot diverging from said common zone in the direction of flow, each slot of said at least one pair of slots narrowing in the direction of convergence into the common zone such that the total flow cross-section of said at least one pair of slots in the region of the zone is 15% maximum of the total wall area offered to the gas stream.
Claim 2
Dependent Claim
147 words
Gas purification apparatus comprising housing means having inlet and outlet means, means for passing the gas through said housing means, a separating wall located in said housing means between said inlet means and said outlet means, and means positioned in said housing means upstream of said wall for spraying wash liquid into said gas stream, said separating wall having at least one first pair of slots converging in the direction of flow and opening into a common zone and at least one other slot diverging from said common zone in the direction of flow, each slot of said at least one pair of slots narrowing in the direction of convergence into the common zone such that the total flow cross-section of said at least one pair of slots in the region of the zone is 15% maximum of the total wall area offered to the gas stream.
