Cyclonic separation apparatus
First Claim
1. A cyclonic separation apparatus comprising a cyclone body having at least one fluid inlet and a fluid outlet, the fluid outlet being concentric with a longitudinal axis of the cyclone body and comprising a vortex finder projecting from an end surface of the cyclone body into the interior thereof, and a centerbody located partially within the vortex finder and projecting beyond the end thereof opposite the end surface so that the distance between the end surface of the cyclone body and the furthermost end of the centerbody is at least twice the smallest diameter of the vortex finder, the cross-sectional area of the centerbody being circular at any point along its length, wherein the centerbody tapers inwardly towards its furthermost end and is hemispherical, conical or frusto-conical in shape.

Abstract
The invention provides cyclonic separation apparatus containing a cyclone body having at least one fluid inlet and a fluid outlet, the fluid outlet being concentric with the longitudinal axis of the cyclone body. The cyclonic separation apparatus also contains a vortex finder projecting from an end surface of the cyclone body into the interior of the cyclonic separator, and a centerbody located partially within the vortex finder. The centerbody projects beyond the distal edge of the vortex finder so that the distance between the end surface of the cyclone body and the further end of the centerbody is at least twice the smallest diameter of the vortex finder, and the cross-sectional area of the centerbody is circular at any point along its length.
