VORTEX DUST COLLECTOR Russian patent published in 2009 - IPC B01D45/12 B04C3/00 

FIELD: technological processes.

SUBSTANCE: invention concerns dust collection. Vortex dust collector includes cylindrical case with top and bottom tangential inlet pipes for gas to be cleaned, deflector disk, axial outlet pipe for cleaned gas and dust collector, permeable cylindrical insert positioned coaxially to the case to form annular clearance between them. Top tangential pipe is made in the form of snail swirler, and bottom pipe features conical swirler mounted along the case axis and hollow truncated cone with base diametre ratio equal to 1:(1.4-1.5) and ring deflector disk on its external surface. Clearance between internal case wall and external surface of cylindrical insert comprises 0.13D, where D is internal case diametre. Cylindrical insert is rigidly attached by horizontal spokes to vertical axis on which fairing is mounted and which is connected to electric motor by transmission.

EFFECT: improved gas treatment efficiency, especially in fine dispersion particle capture.
