Title: Improvements in or relating to sludge centrifuges
IPC: B04B1/08
Filed: 1966-10-26
Abstract: 1,109,609. Centrifugal separators. ALFALAVAL AKTIEBOLAG. 26 Oct., 1966 [26 Oct., 1965], No. 48066/66. Heading B2P. In a sludge centrifuge having a primary inlet pipe 10 for liquid to be centrifuged and a clear liquid outlet in the form of a paring disc 11, means to indicate the sludge level in the separating space 13 of the centrifuge rotor 1 comprise a conduit 22 connecting the space 13 via channels 21, 24 to a paring chamber 23 in which a liquid level closer to the axis of rotation of the centrifuge than the outer edge of the paring disc 11 is sensed by means of a pressure or flow sensing means (not shown) inserted in an outlet duct 26 of a paring disc 25. Liquid is supplied through a secondary inlet pipe 18 via channels 19, 21 and the conduit 22 into the separating space 13 where it mixes with the liquid to be separated. A 'controllable throttling valve (not shown) is inserted in the outlet channel 17 of the paring disc 11 or in a duct connected thereto. Sludge outlets 4 in the centrifuge rotor are normally closed by means of a slide valve 5 urged upwardly by liquid which flows from the channel 21 into a space 6 below the valve 5 and which is acted upon by centrifugal force during rotation of the rotor. The rotor bottom has holes which are kept closed by pads 8 acted upon by a spring-pressed ring valve 9. At the start of an operation, the liquid level is at the same radial distance from the rotor axis in the chambers 13, 16 and 23. Before a significant amount of sludge has been separated, the outlet of the paring disc 11 is throttled in such a way that the liquid level in the chamber 23 moves inwardly and lies just outside the inlet opening of the paring disc 25. As soon as the separated sludge reaches a level corresponding to the opening of the conduit 22 in the space 13, this opening is throttled and liquid from the pipe 18 causes the liquid level in the chamber 23 to move inwardly and to discharge through the paring disc 25 and its associated duct 26. The sensing means inserted in the duct produces an impulse which indicates that the sludge collected ought to be discharged. This can be done manually or automatically by actuation of the ring valve 9 and hence of the piston valve 5.

Title: Process and apparatus for concentrating isotopes by the simultaneous  exchange of heat and mass
IPC: C01B5/02
Filed: 1971-10-30
Abstract: 1363757 Enriching with deuterium V R THAYER 30 Oct 1971 50540/71 Heading C1A In concentrating an isotope, e.g. deuterium, of an element by exchange between physically separable feed fluid and circulating fluid, an exchange vessel having a hot zone and a cold zone is used and the vessel contains at least one conduit which traverses the hot zone and feed fluid is passed through the vessel over the exterior of the conduit, circulating fluid is passed countercurrent to the feed fluid through the vessel over the exterior of the conduit and after passing through the vessel at least one of said fluids is passed through the conduit and at least one of said fluids is withdrawn from a selected point in the vessel, at which point the fluid contains the maximum concentration of isotope. In the embodiment shown in Fig. 1, the fluids are the physically separable liquids water and ethyl mercaptan. Water is introduced into the top of the tower 10 via inlet 16 and flows countercurrently to ethyl mercaptan introduced at the bottom of the tower via inlet 22. The mercaptan leaves the tower via line 12 and is returned down the tower via coil 12a thereby exchanging heat with materials flowing over it. The mercaptan recycles via line 12b. The water leaves the tower by line 13 and passes to steam stripper 11 which removes the mercaptan content of the water which is returned to the tower via line 57. The stripped water leaves via line 14 and after yielding its heat content to the contents of the tower by passing through coil 14b passes to waste. Product of increased deuterium content is withdrawn via line 28 from the centre of the tower and the heat requirements of the exchange process are balanced by means of the cooling coil 17b and the steam coil 26 of the steam stripper. In Fig. 2 an embodiment using liquid water and gaseous H2S is shown. The waterfeed enters tower 100 by line 106, and passes down it countercurrent to a stream of H2S cycling via line 109 from the top to the base of the tower. Water leaving the tower by line 101 is recycled to coil 101b where it acts in heat exchange in section 140 of the tower with the material moving past it. The water leaves the coil by spray 150 falling on to perforated plate 110. Part of the water is withdrawn from the plate via line 102 to steam stripper 120, when the H2S stripped therefrom is returned to section 140 via line 109, and the water heated by steam coil 26 is fed through coil 103b in section 142 of tower 100 and then to waste. The H2S entering via 105 is humidified and heated in section 142 before passing through plate 110. The available heat in section 142 is fed to section 140 by recycling water via line 130 to coil 101b. The heat balance of the process is maintained by steam coil 26 and cooling coil 121b and product of enriched deuterium content is withdrawn via line 160.

The pump delivery pressure is connected through a reversing valve 31 to a line 33 connected to the valve 34 and also to a relief valve 36<SP>1</SP>. On overload the pressure in the line 33 opens the relief valve 36<SP>1</SP> which supplies the pump delivery pressure through a line 46 to a servo 40 which changes over the valve 34 to connect the pump delivery pressure through a variable throttle 42 to a reservoir 38. The pump 28 is thus permitted to rotate to disconnect the drive. The throttle valve 42 controls the rate of disengagement and the rate of breaking of the output. The pressure in the line 46 additionally actuates a switch 39 to stop the driving electric motor. When the driving electric motor 13 is reversed the reversing valve 31 is automatically changed over by a solenoid 32. The valve 34 is additionally operable to the drive disconnect position by a solenoid 48 controlled manually or automatically. A speed reduction through the gearing may be obtained by energizing the solenoid 48 intermittently or by energizing the solenoid 48 and providing a suitable adjustment of the throttle valve 42. The ring gear 17 is externally toothed and is supported by four equi-angularly spaced pinions 26 one of which is connected to the pump 28. The planet carrier 19 of the gearing is connected to an output shaft 12 through a reduction gear 10.
