FLOW-THROUGH SEPARATOR FOR SEPARATION OF DISPERSED PARTICLES FROM GAS 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 helical lines and helical grooves made inside the casing at the angle of at least 45° to rotational axis. Said casing is composed of at least one coiled strip with turns connected along lengthwise edges. Said strip is bent along creases arranged at, at least 45° to said lines to make helical lines and helical surfaces on inner and outer surfaces at, at least 45° to casing rotational axis in the form of polygonal pockets, e.g. rectangle, square, isosceles or scalene trapeziums. Said pockets can differ in sizes over casing perimetre. Distance between flexure lines equals the length of every elements of polygon. Helical spring with device to vary turn pitch by spring compression or expansion is arranged along container length.

EFFECT: higher efficiency of separation.
