Abstract
A dust collector including a cylindrical cyclone tube, a central outlet channel, a swirl generator, and a swirl reflector is disclosed. The cylindrical cyclone tube can include one or more inlets. The central outlet channel includes a lower inlet end and an upper outlet end, wherein the upper outlet end is located above the one or more inlets. The swirl generator can be configured to generate a swirl between the cylindrical cyclone tube and the central outlet channel, the swirl generator configured to encircle the central outlet channel. The swirl reflector can be located near a bottom of the cylindrical cyclone tube and forming a particle chamber there below. A distance between the swirl reflector and the lower inlet end of the central outlet channel can be between ten to fifty percent of the length of the cylindrical cyclone tube from the one or more inlets to the swirl reflector.
