Abstract:
An inertial gas-liquid separator for removing and coalescing liquid particles from a gas-liquid stream, comprising a housing having an inlet for receiving a gas-liquid stream, and an outlet for discharging a gas stream, nozzle structure in said housing having a plurality of nozzles receiving said gas-liquid stream from said inlet and accelerating said gas-liquid stream through said nozzles, an inertial collector in said housing in the path of said accelerated gas-liquid stream and causing a sharp directional change thereof and having a rough porous collection surface causing liquid particle separation from said gas-liquid stream of smaller size liquid particles than a smooth non-porous impactor impingement surface and without the sharp cut-off size of the latter, to improve overall separation efficiency including for liquid particles smaller than the cut-off size of a smooth non-porous impactor impingement surface, said outlet receiving said gas stream after said sharp directional change, wherein said collection surface and said nozzles are spaced by a gap sufficient to avoid excessive restriction, said housing has a flow path therethrough including a first flow path portion for said gas-liquid stream between said inlet and said gap through said nozzles, and a second flow path portion for said gas stream between said gap and said outlet, said flow path having a first directional change in said gap at said collection surface, and a second directional change in one of said first and second flow path portions, and said second directional change is in said first flow path portion.
