FLOW-THROUGH SEPARATOR Russian patent published in 2014 - IPC B01D45/12 B01D46/18 

FIELD: process engineering.

SUBSTANCE: invention is designed to separated dispersed particles from gases or vapours and may be used in power engineering, oil processing, petrochemical and chemical industries. Through-flow separator comprises flanged casing with inlet and outlet and fluid discharge opening. Multi-start helical hollow casing composed of three and more convex curvilinear variable-width shape. Said strips are coiled in vertical plane in lengthwise direction and bent in helical lines in transverse direction on barrel-like mandrel to make helical lines over casing perimetre at angle of 30°-75° and helical convex surfaces relative to casing mirror axis with centre of curvature inside said casing as well as laps therein as screw blades over the entire length of the casing. Helical spring with device to vary turn pitch by spring compression or expansion is arranged along container length.

EFFECT: higher efficiency of separation.
