Title: Method of and apparatus for separating fluent solid particles of varying sizes from gases by means of two or more cyclone separators
IPC: B04C7/00
Filed: 1963-07-12
Abstract: 1,055,151. Cyclone separators. H. SCHLOZ and H. W. SCHLOZ, [trading as MOTORCONDENSATOR-COMPAGNIE SCHLOZ KOMM GES]. July 12, 1963 [July 12, 1962; Sept. 4, 1962], No. 27735/63. Heading B2P. Solid particles of varying sizes are separated from a gas stream by means of a group of two or more series-connected cyclone separators wherein solid particles, heavier than those present in the last cylone of the group, are continuously fed to that last cylone. In one arrangement a partial particle-laden gas flow is branched off in front of the first cyclone of a three-cyclone group and passed through an additional cyclone separator in which coarse particles are separated and added to the main gas stream leading from the second to the last cyclone while the gas and fine particles separated are returned to the gas stream leading from the first to the second cyclone. In another three-cyclone arrangement, the solid particles are obtained by screening a part of the product discharging from the first cyclone and are fed to the gas stream leading to the third cyclone alternatively, some of the products discharging from the first cyclone may be compacted in the form of beads before being fed to the last cyclone. Balsing of the fine solid particles to the coarser ones is improved by wetting the latter. In Fig. 3, external neutral heavy solid particles, e.g. fine sand, are added to the last cyclone 33, discharged with fine particles of the product to be separated into a screening device 36 where the heavy and fine particles are separated from one another by means of a small quantity of gas tapped from the main flow and introduced into the device 36 by a feed unit 38. The heavy particles are recycled to the cyclone 33 by a feed unit 37 and the fine particles are led with the gas component to an auxiliary cyclone 44 for separation. In Fig. 4, the last cyclone of the group is replaced by two smaller cylones 53a, 53b connected in parallel with respect to the main gas stream 54 but in series with respect to each other. The continuous supply of solid particles is carried out in any of the ways referred to above and is introduced at 55 to the cyclone 53a together with a half-portion 54a of the main gas stream 54 leaving cyclone 52 and with a partial flow 60 of gas and separated solid discharging from cyclone 53b. The separated material 61 from cyclone 53a is fed to cyclone 53b together with the other half-portion 54b of the main gas stream 54. Fig. 5 shows a typical cyclone in which the main gas stream enters at 74, the separated material leaves at 75, and relatively the purified gas leaves at 78 and the relatively coarse solidy particles A are fed through a tube 76 discharging above a distributing element 77 whereby the coarse particles collide with the relatively finer particles and calsing of the particles together occurs whereby separation is improved.

Filed: 1955-09-30
Abstract: 800,299. Lubricating. DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ N.V. July 23, 1956 [Sept. 30, 1955], No. 27889/55. Class 12 (3). [Also in Groups XXIV and XXVI] The invention relates to a contra-rotating hydraulic turbine for use in deep-well boring (see Group XXVI). The thrust bearing pads 106 and the radial bearing 124 on which the stub shaft 104 at the lower end of the turbine rotor 4 is mounted are lubricated by means of lubricant contained in the bellows member 118 which is subject on its outer surface to pressure of the turbine working fluid exhaust through an orifice in the cap 111. The bellows member is filled through a channel 121 normally closed by a plug 122. Speed reduction gearing connecting the turbine rotor and stator is disposed in a casing 15 at the upper end of the turbine rotor and stator assembly (which is disposed in a vertical position). The gearing is lubricated by means of lubricant contained in a flexible bellows 46 which is subject on its external surface to pressure of the turbine working fluid by means of apertures 41 in the cap member 40. The bellows is filled with lubricant through a port normally closed by a plug 53. The drill bit shaft 5 is rotatably mounted within the outer housing 7 by means of bearings 21, 22 and 153 and the bearings are lubricated by means of lubricant contained between the annular bellows 160, 161 which are joined at their upper ends by a plate 162, the lubricant chamber being subjected externally to the pressure of the turbine working fluid. The chamber is filled with lubricant through a bore normally closed by a plug 168. The lubricant in the speed-reducing gear may be caused to flow through a heat-exchanger device as shown in Fig. 9, the heat being transferred to the working fluid flowing to the turbine. The lubricant is forced upwardly through a spiral passage 219 formed between tubular parts 211, 212 where it is cooled by turbine working fluid flowing downwardly on the outside of the tubular part 211, the cooled lubricant returning to the gearing downwardly through the central tube 212. Flow of lubricant is caused by pressure due to gear teeth moving into engagement and by motion due to gear teeth moving out of engagement. A bellows 215 between the tube 211 and the gear casing 15 acts as a pressure-balancing device to maintain the pressure of the lubricant within the heat-exchanger and gear casing equal to that of the turbine working fluid. Specification 755,207, [Group XXI], is referred to.
