Duckbill aerosol separator with always open refinement

An impactor separator formed as part of a valve cover, the impactor separator comprising:

• a nozzle assembly positioned within the valve cover having a longitudinal axis, a bottom portion of the valve cover comprising an inlet receiving a gas-liquid stream, and comprising a plurality of nozzles having a nozzle inlet and a nozzle outlet, the plurality of nozzles comprising:
• a central duckbill valve disposed along the longitudinal axis, the central duckbill valve having an always-open orifice, and
• a plurality of duckbill valves disposed around the central duckbill valve;
• and
• an impaction plate having an impaction surface structured to separate liquid particles from the gas-liquid stream;
• wherein the gas-liquid stream enters into the valve cover, flows into the plurality of nozzles through the nozzle inlets and exits the plurality of nozzles through the nozzle outlets, the plurality of nozzles accelerating the gas-liquid stream toward the impaction surface.

A nozzle assembly for use with an impactor separator comprising:

• a nozzle assembly housing portion having a longitudinal axis;
• and
• a plurality of nozzles extending through the nozzle assembly housing portion, each of the plurality of nozzles having a nozzle inlet and a nozzle outlet, the plurality of nozzles comprising:
• a central duckbill valve disposed along the longitudinal axis, the central duckbill valve having an always-open orifice, and
• a plurality of duckbill valves disposed around the central duckbill valve;
• wherein one of the plurality of nozzles is positioned along the longitudinal axis and comprises an always-open orifice.
