FILTER FOR AIR CLEANING Russian patent published in 2018 - IPC B01D46/00 B01D45/08 

FIELD: ventilation.

SUBSTANCE: filter for air cleaning contains a body with a conical bottom made with a hole at the bottom, a cleaned air outlet fitting covered with a wire mesh and having a conical nozzle with grooves on the outer surface, air intake chambers made in the form of tapering subsonic nozzles with curvilinear grooves on the inner surface and having on the side of the air inlet a metal mesh, condensate trap, located in the body bottom opening, and a baffle, springed from the side of the cleaned air outlet fitting, connected to the guide rods by springs. The body of subsonic nozzles is made of bimetal and is provided with an annular groove placed on the inner surface on the side of metal mesh and connected to curvilinear grooves having a dovetail profile. The baffle plate is made porous on the side of cleaned air inlet in the form of tapering nozzles and solid on the side of cleaned air outlet. The inner surface of bottom opening in which the condensate trap is located is coated with a nanomaterial in the form of a glass-like film. The curvature of curvilinear grooves on the inner surface of tapering subsonic nozzles is made along the cycloid line as brachistochrone.

EFFECT: maintenance of normalized power inputs for the production of compressed air for long-term operation by maintaining the constancy of aerodynamic resistance.
