Abstract
An aspirator includes a plurality aspirator tubes, each preferably extending at approximately 70 degrees from a central axis and including a fin extending a limited distance below the aspirator tube outlet. The design improves mixing and gas contact, yet has reduced power requirements, by using a plurality of debris-shedding, finned aspirator tubes to inject approximately 35% more air than the best prior art designs at the same rotational speed. Further, the aspirator of the present invention improves motor life by reducing the average current draw on the motor. The aspirator is useful in many applications, including sewage and wastewater treatment, oxygenation, fermentation, aeration, hydrogenation, oxidation, and oil-sand separation.
Claims19
An aspirator comprising:
- a main body having a central axis, an open first end, a closed second end, and a inner wall defining a hollow interior;
- and
- a plurality of equally-spaced aspirator tubes radially extending from said second end of said main body,
- wherein said aspirator tubes include open-ended conduits in communication at one end with said hollow interior, and
- wherein each aspirator tube further includes a planar fin portion extending from the aspirator tube running less than the length of the conduit from an end opposite the end of the conduit in communication with said hollow interior.
