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.

Centrifuging mixture separator

The apparatus comprises: (a) stacked bundles of parallel corrugated wafers (4) between which the liquid droplet charged gas or vapour is made to flow, said bundles being housed between panels (e.g. 1) which are welded round all their edges to a support structure so as to define a horizontal gas or vapour flow direction between adjacent wafers; (b) gutters (9, 10, 11) for collecting the liquid running down the wafers, each gutter being located below a bundle of wafers; and (c) liquid drain tubes (12, 13, 14) for draining away the liquid collected by the gutters. The lower edges of the wafers are notched in such a manner as to catch drops of liquid flowing along said lower edges and cause them to drop into the gutters rather than being entrained by the flow of the gas or vapour. Such apparatus is used in separator-superheaters as used in power stations that generate electricity by expanding steam through turbines.

Apparatus for separating droplets of liquid entrained in a gas or a vapor

Apparatus for distribution and preliminary separation of a vapor-liquid mixture in a separator with horizontal axis, from a neck 10 on the lower generatrix of the separator, it comprising two symmetrical deflectors 11, 12 in the form of portions of cylinders, with parallel axes perpendicular to that of the separator, each cut by two oblique planes, and completed by three partitions 17, 18. Their edges are provided with troughs 21 for collecting and discharging the water deposited on their concave surface, issuing into spaces separated from the neck. The invention has application to separator-superheaters for wet water vapor from an expansion turbine.

The device includes inside a cylindrical casing with a horizontal axis and parallel to said axis and symmetrical about the longitudinal plane of symmetry:

Device for drying and superheating steam

The heat exchanger comprises an outer cylindrical casing and an inner cylindrical sleeve coaxially mounted therein. Dry superheated steam circulates in the jacket between the outer casing and the inner sleeve, and may be extracted at any convenient point along the casing. Wet steam is introduced into the inner casing whose lower portion comprises a separation baffle for removing water from the wet steam and whose upper portion has nests of heat exchanging tubes for superheating the steam.
