FLOW-THROUGH SEPARATOR FOR SEPARATION OF DISPERSED PARTICLES FROM GAS Russian patent published in 2013 - IPC B01D45/12 B01D45/16 B01D45/06 

FIELD: process engineering.

SUBSTANCE: invention relates to through-flow separator comprises flanged casing with inlet and outlet and fluid discharge opening. Casing perimetre represents multistart helical surface with helical grooves inside and outside of said casing in the form of pockets with their centres of curvature alternating outside and inside of casing cross-section. Said casing is composed of one equal-width strip coiled in helical turns interconnected along lengthwise edges and bent in wavy manner over flexure lines located at the angle thereto. This allows forming unidirectional curvilinear pockets on outer and inner surfaces directed towards aforesaid helical surfaces. Said pockets can vary in both shape and sixe along perimeter of rods-rolls. Distance between flexure lines equal the sum of perimeters of pockets of inner and outer surfaces. Helical spring with device to vary turn pitch by spring compression or expansion is arranged along container length.

EFFECT: higher efficiency of separation, expanded performances.
