VORTEX FINDER FOR CYCLONE SEPARATOR Russian patent published in 2018 - IPC B04C5/13 

FIELD: centrifugal devices for physical or chemical processes.

SUBSTANCE: group of inventions refers to a vortex finder for a cyclonic separator and to a cyclonic separator comprising a vortex finder according to the invention. Vortex finder for a cyclonic separator for allowing air flowing about an axis of a cyclone chamber to pass to an outlet, the vortex finder comprising a plurality of stationary vanes spaced radially around said axis when installed in a cyclone chamber. Vanes being positioned relative to each other so a helical flow of air about the axis of the cyclone chamber passes over an outer surface of the vanes with a portion of the air flow being redirected around a leading edge of each vane, while a portion of the air flow is redirected around the leading edge of each vane and through the gap between adjacent blades to discharge. At any point along the axis, a portion of an outer surface of each vane lies on a circle having its center coaxial with said axis, wherein the outer surface of each vane having a portion leading towards the leading edge that extends inwardly away from the circle so that the leading edge of each vane about which air is redirected through the gap between vanes is located within a region bound by said circle.

EFFECT: technical result is a reduction in the pressure drop to increase the air flow, which increases the separation efficiency of the contaminants.
