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. Proposed swirler is made up of tape bent along straight lines and arranged at an angle to tale lengthwise edges. 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 to make multistart screw surface with unidirectional screw lines and surfaces arranged at 5°-45° to case lengthwise angle. Said screw surface represent polygonal screw pockets. Said pockets represent various geometrical figures with, at least, four lateral sides.

EFFECT: higher efficiency, lower flow friction.
