Abstract
An inertial gas-liquid impactor separator has a de-icer for preventing ice accumulation at the acceleration nozzles. A heater heats a nozzle plate to minimize plugging of acceleration nozzles otherwise due to icing.
Claims6
An inertial gas-liquid impactor 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, a nozzle plate in said housing, said nozzle plate having at least one nozzle 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 from gas-liquid stream, a heater in said housing heating said nozzle plate to minimize plugging of said nozzle otherwise due to icing, wherein said heater is downstream of said inlet and thermally coupled to said nozzle plate such that said gas-liquid stream passes through said inlet unheated by said heater, whereafter said gas-liquid stream is heated by contact with said nozzle plate, said nozzle plate comprises an electrically resistive element heated by electric current flow therethrough, whereby said heater is an electrical resistance heater and is provided by said nozzle plate itself.
An inertial gas-liquid impactor 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, a nozzle plate in said housing, said nozzle plate having at least one nozzle 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 from gas-liquid stream, a heater in said housing heating said nozzle plate to minimize plugging of said nozzle otherwise due to icing, wherein said heater is downstream of said inlet and thermally coupled to said nozzle plate such that said gas-liquid stream passes through said inlet unheated by said heater, whereafter said gas-liquid stream is heated by contact with said nozzle plate, and comprising a pair of electrical conductor wires passing into said housing for supplying electric current to said heater.
An inertial gas-liquid impactor 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, a nozzle late in said housing, said nozzle plate having at least one nozzle 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 from gas-liquid stream, a heater in said housing heating said nozzle plate to minimize plugging of said nozzle otherwise due to icing, wherein said heater is downstream of said inlet and thermally coupled to said nozzle plate such that said gas-liquid stream passes through said inlet unheated by said heater, whereafter said gas-liquid stream is heated by contact with said nozzle plate, said heater is selected from the group consisting of an inductive heater, including a coil heater and a dielectric heater, a Peltier thermoelectric heater, and a passive heater, including a heat exchanger, said heat exchanger derives heat from hot engine fluid in an internal combustion engine application.
