Abstract:
A reverse cyclone separator including:a container closed at one end; an inlet for introducing a fluid mixture swirling about an axis at a region of the container remote from the end; an outlet for lighter phase of the mixture, the outlet opening from the region; a member mounted centrally within the container, the member being closed off from fluid communication with the container; and a barrier mounted around the member and in a fluid flow path between the region and the closed end, the barrier having a surface facing the inlet and extending towards the outer wall of the container leaving a gap therebetween, and having an outer perimeter which extends in the axial direction a distance not less than the radial extent of the gap; wherein the outlet comprises a chamber formed by the member and a foraminated shroud mounted around the member, the width of the chamber increasing with distance from the barrier, the arrangement being such that in use fluid flows with substantially constant velocity in the chamber.
