DEVICE FOR SEPARATING DISPERSE PARTICLES FROM GAS Russian patent published in 2014 - IPC B01D45/12 B01D46/18 

FIELD: oil and gas industry.

SUBSTANCE: device for separating disperse particles from gas contains a body equipped with flanges, with inlet and outlet openings and an opening for liquid removal. Along the perimeter the body is made as multiple-thread helical surface with helical grooves inside the body as curved pockets with centres of the above pockets curvature placed inside cross-section of the body. The body is made of three and more rectangular strips twisted in longitudinal direction along the longitudinal axis and curved along the helix line in longitudinal direction at the cylindrical former thus forming three and more inner curved convex surfaces with the centres of curvature inside the body and forming laps inside the body formed as screw blades along the body length from the inlet opening up to the outlet one. Inside the body there is a helical surface of cylindrical shape with rectangular cross-section of turns; the surface is equipped for turn pitch changing by means of stretching or compression.

EFFECT: improvement of effective separation of disperse particles from gas.
