Abstract:
An apparatus which collects and separates particles from a particle laden gas stream, comprising:a cyclone cone;a vortex tube assembly axially centered within an upper portion of said cyclone cone;an apex outlet passage in a lower portion of said cyclone cone, whereby concentrated particles are removed from within said cyclone cone;a vortex passage within said vortex tube assembly, whereby gases, moisture, and ultra fine particles are removed from within said cyclone cone;a high aspect ratio angled input nozzle penetrating a wall of said cyclone cone, whereby said particle laden gas stream is admitted into said cyclone cone outside said vortex tube assembly;said cyclone cone and said vortex tube assembly being at different voltages so that an electric potential exists between said cyclone cone and said vortex tube assembly such that electrically charged particles having electrical characteristics within said gas stream are either attracted or repelled, respectively, depending on said electrical characteristics of said charged particles; andsaid cyclone cone being electrically grounded so that electrically charged particles electrically polarized similar to an electric polarity of said vortex tube assembly are repelled from said vortex tube assembly, whereby said charged particles pass through said apex outlet passage.
