Abstract
A separator for separating a mixture of a vapor (or as gas, or a liquid) and of a liquid (or a solid) by centrifuging the mixture inside a chamber (2) which encloses at least one cell constituted by: a central core (120); at least one circulation tube (100); a swirler device (102) for imparting swirling flow to the mixture at the inlet to the, or each, circulation tube; a collector tube (103) for collecting a less dense portion of the initial mixture, said collector tube being installed at the outlet from the, or each, circulation tube and optionally being provided with an unswirler device (104) for unswirling the flow; at least one extractor device (105) for extracting a denser portion of said mixture; at least one collector device (107) for collecting said denser portion; and reinjection means for reinjecting a part of said denser portion into the mixture to be separated or being separated; wherein the reinjection means comprise at least one extractor duct (130) connecting the collector device (107) and the central core (120) downstream from the unswirler device (104), and reinjection channels (116) made in the central core downstream from the swirler device.
