Inertial gas-liquid impactor separator with flow director
An inertial gas-liquid impactor separator includes flow director guidance structure directing and guiding flow through the housing from the inlet to the outlet along a flow path from upstream to downstream. The flow director guidance structure may include a flow controller controlling and directing flow.
1. An inertial gas-liquid impactor separator for removing 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, at least one nozzle in said housing receiving said gas-liquid stream from said inlet and accelerating said gas-liquid stream through said nozzle, an inertial impactor collector in said housing in the path of said accelerated gas-liquid stream and causing liquid particle separation, and a flow director directing flow through said housing from said inlet to said outlet along a flow path from upstream to downstream, the flow director comprising a flow controller comprising a hinged plate extending across said nozzle.
2. The inertial gas-liquid impactor separator according to claim 1 , wherein said hinged plate comprises a cap having an aperture therethrough, providing a tea kettle valve.
3. The inertial gas-liquid impactor separator according to claim 2 , wherein said separator is provided for an internal combustion engine generating blowby gas as said gas-liquid stream, including increasing flow and pressure as said engine ages and wears.
4. The inertial gas-liquid impactor separator according to claim 3 , wherein said tea kettle valve aperture maintains a desired pressure drop during an early-in-life condition of said engine at low blowby gas flow.
5. The inertial gas-liquid impactor separator according to claim 4 , wherein said tea kettle valve cap opens in response to increasing blowby gas flow to maintain a designated pressure drop during a late-in-life condition of said engine at higher blowby gas flow.
6. The inertial gas-liquid impactor separator according to claim 1 , wherein the at least one nozzle comprises a plurality of nozzles, and wherein the hinged plate extends across the plurality of nozzles.
7. The inertial gas-liquid impactor separator according to claim 2 , wherein the cap is movable to open and close the at least one nozzle.
8. The inertial gas-liquid impactor separator according to claim 7 , wherein the cap has the aperture passing flow therethrough, including when the cap is closed, to maintain a given pressure drop at a given low flow condition.
9. The inertial gas-liquid impactor separator according to claim 8 , wherein the cap opens in response to increased flow to maintain a designated pressure drop at a designated higher flow condition.
10. The inertial gas-liquid impactor separator according to claim 1 , wherein the at least one nozzle comprises a single nozzle, and wherein the hinged plate extends across the single nozzle.
