AIR-OIL SEPARATOR WITH JET-ENHANCED IMPACTION AND METHOD ASSOCIATED THEREWITH

摘要

The combination of a gas-pressure-driven pump jet nozzle or alternatively Coanda effect nozzle with an impactor nozzle(s) in an air-oil separator for separating oil from blow-by gasses from a crankcase of an internal combustion engine, or for separating liquid aerosol from gas, in general. Such combination enhances impaction efficiency and enables operation at higher pressure differentials (or pressure drop) (“dP”) without causing excessive backpressure in the air-oil separator.

1. A gas-liquid separator, the gas-liquid separator comprising:
a housing having an inlet for receiving a gas-liquid stream; an impactor nozzle plate supported by the housing and situated downstream of the inlet, the impactor nozzle plate receiving the gas-liquid stream; an impactor nozzle extending through the impactor nozzle plate and providing a passage for the gas-liquid stream to pass through the impactor nozzle plate, thereby creating a pressure differential between an upstream end of the impactor nozzle and a downstream end of the impactor nozzle when the gas-liquid stream is passed through the impactor nozzle plate; and a pressurized gas jet nozzle that injects a high-velocity gas stream into the gas-liquid stream so as to decrease the pressure differential.
