1,259,711. Centrifugal separators. GENERAL ELECTRIC CO. 21 Nov., 1969 [21 Nov., 1968], No. 57192/69. Heading B2P. [Also in Division G6] A gas-liquid separator for use as a steam water separator in a nuclear reactor steam generator (see Division G6) comprises an elongated vortex tube 36, Fig. 2, having a gas-liquid mixture inlet 31 at one end and an outlet at the other end; a vortex generator 32 adjacent the inlet 31 for receiving a gasliquid mixture and for establishing in the tube 32 a gas vortex surrounded by a liquid vortex; a liquid discharge channel 38 surrounding the vortex tube; a tubular pick-off ring 42 and an annular cover 41 adjacent the outlet of the vortex tube for directing the liquid vortex into the discharge channel 38; and a number of longitudinal, vanes 43 positioned in the discharge channel 38 for arresting the vortex flow of the liquid, the vanes having axially directed leading ends. An annular flow-restriction ring 44 is provided in the channel 38 to maintain a minimum thickness of the liquid vortex in the tube 36. The gas vortex passes through a tube 37 into a dryer 23 comprising a tube 55 against which liquid carried by the gas is separated out and directed by a pickoff ring 57 and an annular flange 58 to a channel defined between the tube 55 and a surrounding tube 59. A gas-liquid mixture from the boundary between the steam and water vortices in the tube 36 flows between the pick-off ring 42 and the tube 37 and is directed by an annular cover 48 into an outer channel 46 within which are arranged vertical chambers 49 and baffles 51, Fig. 4. Assuming a counterclockwise rotation of the mixture entering the channel 46, each chamber 49 is formed of a front member 52, a perforated rear member 53 and a top member 54. The mixture first encounters the front members 52 and the baffles 51 which arrest its rotation and turn the mixture downwards as shown by the solid arrows. The resulting centrifugal force causes the gas to flow, as shown by the dashed arrows, through the perforations in the members 53 into the chambers 49 and out through exit openings 56 formed in the outer tube 47, while the water flows downwards. |
