STRAIGHT FLOW SWIRLER Russian patent published in 2012 - IPC B01D45/16 

FIELD: process engineering.

SUBSTANCE: invention relates to gas or fluid swirlers incorporated with cyclone fluid drop separators to be used in chemical, oil-and-gas industries, etc. Tape is coiled into helical layers interconnected by lengthwise edges to make hollow case. At least, one equal-width tape is coiled into helical layers. Said tape is coiled into helical layers to make multistart screw surface with unidirectional screw lines and surfaces arranged at 5°-45° to case lengthwise angle. Said grooves represent curved pockets with center of curvature located inside case cross-section. Said pockets may differ in size and shape while distance between crease lines equal the sum of lengths of pocket inner and outer surface perimetres.

EFFECT: higher efficiency, lower flow friction.
