Abstract
In a tornado-flow vortex generator for separating particulates from gases, having a cylindrical vortex chamber, an inlet tube for raw gas coaxially disposed in the vortex chamber and terminating in a nozzle for providing an advance rotation in a flow of the raw gas therethrough, a hopper diaphragm surrounding the inlet tube and formed, in vicinity of the vortex-chamber casing, with an annular particulate-discharge slot communicating with a space within a hopper, a clean-gas outlet disposed in the vortex chamber spaced from and opposite the raw-gas inlet tube, an auxiliary-gas outlet surrounding the clean-gas outlet, and an auxiliary-gas inlet disposed at the vortex-chamber casing for blowing auxiliary gas into the vortex chamber at an inclination and tangentially to the casing thereof and connected by a blower to the auxiliary-gas outlet, the improvement includes a line having valve means and connecting the hopper space with a location of the vortex generator at which a pressure exists which is lower than the pressure in the hopper space.
