ABSTRACT:
A vortex tube gas cleaning device 10 is used to clean a particle containing gas flow stream of particles. The device 10 has an outer tube 12 having an inlet 14 at an upstream end, and, in series downstream of the inlet 14 a vortex generator 16 in a vortex region 18, and a separation region 20. An inner extraction tube 30 is located at the downstream end of the tube 12 and extends concentrically within the outer tube 12, upstream, canti-lever fashion. A peripheral outlet region 24 is defined annularly around the inner tube 30 downstream of the separation region 20 and leads to outlet ports 48. A central outlet region 28 is defined within the inner tube 30 downstream of the separation region 20 and leads to an outlet. The manner of location of the inner tube 30 ensures that the peripheral outlet region 24 is continuous or uninterrupted, especially also through an annular orifice 29. Upstream extremities 50 of the ports 48 are spaced from the annular orifice 29 a distance at least 25% of the nominal diameter of the tube 12.
