SEPARATING-AND-FILTERING DEVICE Russian patent published in 2010 - IPC B04C9/00 B01D45/00 

FIELD: mechanics.

SUBSTANCE: invention is intended for separation of mechanical impurities and liquid drops from a gas flow. The device contains an outer and an inner housings, a cover and a bottom, an inlet nipple mounted on the outer housing, an outlet nipple arranged inside the cover, a drain nipple arranged inside the bottom, coaxial cylindrical shells contained inside the circular space between the outer and an inner housings and forming slot channels inside the said space, crosswise partitions whereon the coaxial cylindrical shells are mounted, a filtering element installed inside the inner housing and separating its inner part into the pre-filtering space and the post-filtering space connected to the outlet nipple. The crosswise partitions are shaped as cones all of them except the bottom one having cutouts for gas flow passage in their conic surfaces. The coaxial cylindrical shells have longitudinal slots providing for the shells shape segmentation. The crosswise partitions, together with the cylindrical shells mounted on them or separation sections serially interconnected with the cutouts on the crosswise partitions.

EFFECT: high degree of decontamination, extended service life of the filtering elements, reduction of overall dimensions and provision for the required device fabrication feasibility.
