Abstract
An eductor apparatus has an inlet nozzle section with a primary inlet and a nozzle, a mixing chamber connected to the inlet nozzle section and in fluid communication with a narrow diameter opening of the nozzle, and a diffuser section connected to the mixing chamber opposite the inlet nozzle section. The diffuser section has throat formed therein. The throat has a plurality of lobes formed thereon. The plurality of lobes extend longitudinally along the throat. The lobes are generally equally circumferentially spaced from each other around the throat. The narrow diameter opening of the nozzle has another plurality of lobes formed therearound and extending in longitudinally alignment with the plurality of lobes of the throat.
Claims16
An eductor apparatus comprising:
- an inlet nozzle section having a tubular portion extending to a nozzle, said tubular portion having a primary inlet formed therein, said nozzle having a wide diameter opening to said primary inlet of said tubular portion and a narrow diameter opening adjacent an end of said nozzle opposite said wide diameter opening;
- a mixing chamber connected to said inlet nozzle section and in fluid communication with said narrow diameter opening of said nozzle, said mixing chamber having an induction port opening thereto and extending therefrom;
- a diffuser section connected to said mixing chamber opposite said inlet nozzle section, said diffuser section having a secondary inlet formed therein and opening to said mixing chamber, said secondary inlet narrowing in diameter from said mixing chamber, said diffuser section having a throat formed therein adjacent an end of said secondary inlet opposite said mixing chamber, said throat having a plurality of lobes formed thereon, said diffuser section having a diffuser having a narrow diameter opening adjacent said throat and a wide diameter opening at an end of and diffuser opposite said throat, each of said plurality of lobes having a concave curved surface facing said flow passageway, said throat having a flow passageway therein, said plurality of lobes extending into said flow passageway.
An eductor apparatus comprising:
- an inlet nozzle section having a tubular portion extending to a nozzle, said tubular portion having a primary inlet, said nozzle having a wide diameter opening to said primary inlet of said tubular portion and a narrow diameter opening adjacent an end of said nozzle opposite said wide diameter opening, said inlet nozzle section having a non-tapering section extending from said narrow diameter opening, said non-tapering section of said inlet nozzle section having a first plurality of lobes formed therearound;
- a mixing chamber connected to said inlet nozzle section and in fluid communication with said narrow diameter opening of said nozzle, said mixing chamber having an induction port opening thereto and extending therefrom;
- and
- a diffuser section connected to said mixing chamber opposite said inlet nozzle section, said diffuser section having a secondary inlet formed therein and opening to said mixing chamber, said secondary inlet narrowing in diameter from said mixing chamber, said diffuser section having a throat formed therein adjacent an end of said secondary inlet opposite said mixing chamber, said throat having a second plurality of lobes formed thereon, said diffuser section having a diffuser having a narrow diameter opening adjacent said throat and a wide diameter opening at an end of and diffuser opposite said throat.
