Definitions

  • a vortex is imposed on the primary flow by a vortex forming device in the form of a central annular hub member having an outer periphery, angularly spaced nozzles leading to the periphery and an interior conduit for supplying high pressure gas to the nozzles.
  • the nozzles are dimensioned and positioned to dis charge a ring of high velocity jets of gas perpendicular to the primary flow and generally tangent to the periphery to create a vortex to submit the particles to centrifugal force, facilitating the separation or classification thereof.
  • FIG. 1 is a view in side elevation of an air cleaner incorporating the present invention, portions thereof being shown in section and portions being broken away;
  • FIG. 6 is a graph comparing efficiency of the present invention with that of a typical low pressure, high flow rate prior art device
  • a tangentially extending discharge tube 17 is connected to opening 16.
  • an automatic dust evacuator valve 18 is normally constructed from aflexible material such as rubber and is provided with a slot or discharge opening at its bottom end. Fluctuations in pressure within the system cause the valve to periodically open to discharge dirt being removed from the air stream by the air cleaner.
  • said outer peripheral surface of said hub member includes a plurality of generally radially extending walls each having one of said tangentially directed nozzles therein, and a like plurality of said ramp surfaces therebetween, each of said ramp surfaces being curved in a radially increasing manner downstream from said nozzle to enhance said Coanda effect.
  • a particle separator employing vortex forming ap paratus comprising:
