FILTRATION DEVICE Russian patent published in 2012 - IPC B01D29/00 B01D36/00 

FIELD: process engineering.

SUBSTANCE: invention is intended for separation of contaminants from fluid by means of filtration element. Proposed device comprises filtration element arranged filter casing. Note here that the latter has swirling chamber to make fluid flow to be filtered partially flowing over filtration element in vortex flow. Swirling chamber is formed by filter casing conical extension toward one or two ends of casing cone. Inlet of unfiltered fluid penetrates into filter case out of alignment with filtration element lengthwise axis. Filter casing conical extension in area of swirling chamber changes into casing cylindrical part or in part with smaller taper. Filtration element converges from swirling chamber to free end.

EFFECT: better filtration capacity.
