A B S T R A C T VORTEX TUBE SEPARATING DEVICE 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 19. An inner extraction tube 40 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 22 is defined annularly around the inner tube 40 downstream of the separation region 19 and leads to an outlet port 36. A central outlet region 24 is defined within the inner tube 40 downstream of the separation region 19 and leads to an outlet 48. A ring 50 which is integral with the inner tube 40 extends into the outer peripheral region 22. It has an oblique leading wall 52 leading to a crown defining an annular orifice 54. The wall 52 forms an acceleration region via which flow in the region 22 is accelerated toward the annular orifice 54. The wall 52 commences spatially downstream of a leading edge of an inlet 42 into the tube 40. The leading edge blends into an aerodynamic lip 43.
