Abstract
A vortex finder, for a cyclonic separator, includes a plurality of stationary vanes having a round convex front end around which incoming air is guided into the vortex finder, wherein, where air separates from the plurality of stationary vanes inside of the vortex finder, a cross-section of the plurality of stationary vanes has only one sharp edge. Preferably, a mean line of the cross-section of the plurality of stationary vanes does not cross a chord line in an upstream half of the cross-section. Preferably, a side of the plurality of stationary vanes facing the incoming air is provided with a protrusion at a stagnation point. The protrusion may be shaped so as to guide the incoming air into the vortex finder, and may have a concave side following a shape of a neighboring vane, and a rounded top.
