摘要： An apparatus which performs solids particles separation from a liquids/solids slurry, and subsequent drying of such solids particles, within a single enclosure. Further processing functions, such as reslurry washing, plug washing, crystal growth and other reactions, can also be carried out within that single enclosure. The single enclosure comprises a partly perforated centrifuge drum (2) which can be rotated about a vertical axis at a fast speed at which the centrifugal effects on material in the drum are substantial so that partly dried solids collect in a substantially cylindrical form on the side wall of the drum, and a slow speed at which the centrifugal effects on material in the drum are negligible; a stripping mechanism (10) which is displaceable within the drum (2), when the drum (2) is rotated at slow speed, for dislodging solids which have been built up on the side wall of the drum during rotation at high speed ; and means (15) for heating at least a bottom part of the drum on which partly dried solids collect when dislodged by the stripping mechanism from the side wall of the drum. The solids can themselves thus be heated, or otherwise processed, to cause evaporation therefrom of any remaining liquid.

摘要： A method of separating solid particles from the liquid constituent of a slurry, containing solids having a «wide» particle size distribution, that is, a size distribution wherein the equivalent diameter of particles in the slurry ranges between at least 15 microns and 150 microns. The method uses a screen bowl centrifuge and comprises:
(a) establishing a bed of solids on the screen of the centrifuge whose maximum radial thickness is greater than 15 times the mean particle equivalent diameter of said solids in the slurry; (b) operating the scroll of the centrifuge at a speed within the range of 0.5 to 10% of the bowl speed; and (c) returning at least a portion of the solids contaminated centrate from the centrifuge to the interior of the screen section of the bowl so as to deposit the centrate on the solids passing over the screen section at or adjacent a region of maximum solids thickness. A portion of the centrate from the centrifuge, contaminated with the fine solids, is returned to the interior of the screen section of the bowl by way of an auxiliary feed pipe. The pipe is so arranged as to cause the centrate to be deposited on the solids passing over the screen section.

摘要： A multi-phase separation process which is particularly useful in connection with the cleaning of cuttings resulting from conventional oil drilling techniques.
A mixture of carrier liquid (sea water), a contaminant liquid (oil) and solids cuttings is passed over the screen of a screen bowl centrifuge while simultaneously washing the mixture with further sea water whereby a finer portion of the solids particles is washed through the screen taking with it the contaminant liquid oil which has been washed off the solids by the sea water and which adheres to the finer solids particles, thereby leaving the remaining, larger solids particles substantially free of oil of the "available" type which adheres to solids particles by surface tension forces only and can therefore be detached from such particles solely by immersion or washing in the carrier liquid.
Separation of the finer solids particles from the sea water carrier liquid is achieved in a secondary centrifuge.

摘要： A method and apparatus for removing carrier liquid from solids particles separated from a liquid slurry in a decanter-type centrifuge, a further liquid is introduced into the bowl which is both immiscible with and of higher specific gravity than the carrier liquid to establish at the periphery of the bowl a body (42) of this further liquid defining a transfer zone (46) disposed radially outwardly of the body (48) of carrier liquid, the solids separated from the carrier liquid by centrifugal action moving into said transfer zone (46) where carrier liquid adhering to the solids particles is displaced by the second liquid of higher specific gravity, the solids particles being scrolled through said transfer zone to the solids outlet of the bowl. For isolating the body of carrier liquid (48) from the frusto-conical portion (18) of the bowl, an annular disc (54) is mounted on the conveyor (20) with its outside periphery extending into the body of liquid (42) so that when the solids are scrolled from the transfer zone up the frusto-conical portion of the bowl to the solids discharge outlet. they are not recontaminated by carrier liquid.

摘要： A centrifuge, for example a decanter type centrifuge, comprises a bowl (10) rotatable about a longitudinal rotational axis (Y), an inlet (14) for feeding into the bowl a slurry to be separated, and a helical scroll conveyor (12) rotatably mounted about the rotational axis and adapted to be rotated within the bowl at a different speed from that of the bowl in order to scroll particles adjacent to the bowl wall to a solids discharge end of the bowl. The decanter further comprises a plurality of walls (23) at least partly submerged in the centrate and defining passages therebetween.
By providing a plurality of passages, through which the centrate to be clarified can travel, particles (e.g. solids) to be separated from the centrate have a short distance to travel under centrifugal force before entering the boundary layer at the walls of the passages. This enables more of the fine particles in the centrate to be separated out.
