Abstract:
A method of separating particles from a fluid stream comprising:passing the fluid with particles into an inlet of a cyclone filter; passing the fluid with particles through a distribution channel formed between an outside radius of a ring and a larger radius of a cylindrical chamber; passing the fluid with particles through a plurality of grooves in the ring; spiraling the fluid with particles down a downflow annulus formed between a vortex finder tube and an intermediate tube; providing a collection chamber having a cylindrical upper portion and a frustoconical lower portion; removing the particles from the fluid by contacting the fluid with particles with a deflector located within the cylindrical upper portion of the collection chamber, the fluid reversing direction upon contact with the deflector; collecting the particles in the lower frustoconical portion of the collection chamber; and expelling the fluid through a fluid outlet at an upper end of the vortex finder tube.
