DUST SEPARATOR Russian patent published in 2010 - IPC B01D45/12 

FIELD: mechanics.

SUBSTANCE: invention is intended for dust collection. The dust separator includes a volute twister with an inlet nipple with a gate, an asymmetrically position gas outlet axial nipple, a slot with a gate mounted on the curvilinear wall of the volute twister and communicating with the remotely mounted counterflow cyclone discharger positioned outside the housing; connected to the axial nipple for purified gas outlet of the discharger is an untwister connected to the volute twister via a gas duct and a slot with a gate. Connected to the gas outlet axial nipple of the volute twister is a counterflow conic cyclone with an axial purified gas outlet. The remotely mounted counterflow cyclone discharger and the counterflow conic cyclone are equipped with transit-receivers with shuttles containing vertical dust standpipe.

EFFECT: improved efficiency and stability of dust collection process, improved operational reliability of the dust collector at fluctuations of dispersity and concentration of dust in the dusted flow, operational stabilisation of the high efficiency counterflow conic cyclone.
