VORTEX DUST CATCHER Russian patent published in 2006 - IPC B01D45/12 

FIELD: different branches of industry; equipment for gases purification from a dust.

SUBSTANCE: the invention is pertaining to the equipment for gases purification from a dust and may be used in various branches of industry in pneumatic transportation systems, pneumatic dust handling equipment, in aspiration. The vortex dust-catcher contains a body consisting of two cylindrical sections of different diameter and a conical section; an axial inlet of a dusty gas with a vortex generator and a deflecting washer; and also the located in the upper part of the body an axial branch pipe for withdrawal of the purified gas and a peripheral inlet of the secondary torrent with a vortex generator. The axial inlet of a dusty gas has a peripheral vortex generator with a tilt angle of the feeding branch-pipe equal to the tilt angle of peripheral inlet of the secondary torrent, and a profile of the cross-section of the deflecting washer is made in such a manner, that its maximal diameter lies in the plain of junction of the cylindrical sections of the body. The surfaces of a dusty gas inlet and the body are coated with the vibration damping a material. At that the ratio of the depth of the treated components to the depth of the layer of the vibration damping material is as 1:(2.5...4). The technical result of the invention is an increased effectiveness of separation of the particles with a small specific weight, improved reliability of the system operation, a decreased hydraulic resistance and the noise level of the dust-catcher operation.

EFFECT: the invention ensures an increased effectiveness of separation of the particles with a small specific weight, improved reliability of the system operation, a decreased hydraulic resistance and the noise level of the dust-catcher operation.
