Patent ID: 8202352

Claim:
A wetted wall cyclone comprising: a cyclone body having a central axis and including an inlet end, an outlet end, and an inner flow passage extending therebetween, wherein the cyclone body has an inner surface defining an inner diameter; a cyclone inlet tangentially coupled to the cyclone body proximal the inlet end, wherein the cyclone inlet includes an inlet flow passage in fluid communication with the inner flow passage of the cyclone body; a skimmer extending coaxially through the outlet end of the cyclone body, wherein the skimmer comprises an upstream end disposed within the cyclone body, a downstream end distal the cyclone body, and an inner exhaust passage extending between the upstream end and the downstream end, wherein the inner exhaust passage is in fluid communication with the inner flow passage of the cyclone body; a first annulus positioned radially between the upstream end of the skimmer and the outlet end of the cyclone body, wherein the first annulus has a radial width W 1 between 3% and 15% of the inner diameter of the cyclone body.
