Patent Application - SYSTEMS AND METHODS FOR REDUCING PARTICULATE EMISSIONS > Claims

  • 1. A particle separator for removing particles from a gaseous stream, the particle separator comprising: a separator body having a centerline axis and a peripheral wall defining a separation chamber;a fluid inlet in fluid communication with the separation chamber;a particle outlet in fluid communication with the separation chamber;a fluid outlet in fluid communication with the separation chamber; anda vortex tube having a hollow interior and a peripheral wall extending along the centerline axis and fluidly coupling the fluid outlet and the separation chamber.
    • 2. The particle separator of claim 1, wherein the peripheral wall of the vortex tube further comprises a plurality of angled outlet apertures fluidly coupled between the hollow interior and the separation chamber.
      • 3. The particle separator of claim 2, wherein the angled outlet apertures are aligned in the direction opposing the inlet flow.
    • 4. The particle separator of claim 1, wherein the vortex tube a cross-sectional shape which correlates to the shape of the separation chamber.
    • 5. The particle separator of claim 1, wherein the vortex tube tapers from a first diameter at one end of the separator body to a second diameter smaller than the first diameter at the other end of the separator body.
    • 6. The particle separator of claim 1, wherein the vortex tube is unitarily formed with the separator body.
    • 7. The particle separator of claim 1, wherein the vortex tube has a free end with a radially outwardly projecting lip.
      • 8. The particle separator of claim 7, wherein the peripheral wall of the vortex tube further comprises a plurality of tangential inlet apertures fluidly coupled between the hollow interior and the separation chamber.
      • 9. The particle separator of claim 7, wherein the vortex tube is unitarily formed with the separator body.
    • 10. The particle separator of claim 1, wherein the vortex tube has a free end with a plurality of apertures for directing a portion of a gaseous stream axially and radially outwardly from the free end.
      • 11. The particle separator of claim 10, wherein the peripheral wall of the vortex tube further comprises a plurality of tangential inlet apertures fluidly coupled between the hollow interior and the separation chamber.
      • 12. The particle separator of claim 10, wherein the vortex tube is unitarily formed with the separator body.
