摘要： PCT No. PCT/GB94/00132 Sec. 371 Date Jul. 20, 1995 Sec. 102(e) Date Jul. 20, 1995 PCT Filed Jan. 24, 1994 PCT Pub. No. WO94/17892 PCT Pub. Date Aug. 18, 1994A slurry is subjected to a filtration and washing process in order to separate the liquor from the solids. The filtration and washing process is carried out in a housing (101) enclosing an inert gaseous atmosphere which also passes through the filter cake and may be recycled, after treatment, to remove contaminants therefrom. To prevent recontamination of the filter cake as a result of the recycled gas entraining contaminant vapors within the housing (101), the gas is introduced into the housing (101) at a downstream location (152a, 166) relative to the direction of travel of the filter cake on a movable filter medium (100) and in such a way as to develop a contaminant concentration gradient whereby the cleanest cake is contacted by gas having the lowest contaminant level.

摘要： An automatic filter cleaning system which includes a solvent dewaxing filter which removes wax from a wax mix slurry and provides a filtrate. Status control apparatus is connected to the filter for affecting the operational status of the filter. Drain apparatus responsive to a control signal controls draining of the filter. Cleaning apparatus is also connected to the filter. A control network connected to the status apparatus, the draining apparatus and the cleaning apparatus controls those apparatus in a manner so as to automatically change the state of the filter from an operational state to a down state to drain the filter and to clean the filter while the filter is in the down state.

摘要： An assembly for separating solid phase material from a slurry that comprises a pressurized filtration unit including a vessel and filter media. A slurry (5) is fed to the filtration unit (10), where it is separated into a solid phase material and a liquid phase material. The filtration unit (10) has a solid outlet (12) for discharging the solid phase material to a material transport (15). The material transport (15) moves the solid phase material to a depressurizing chamber (20) that has a lower pressure than the filtration unit (10). As the solid phase material enters the depressurizing chamber (20), it is exposed to the lower pressure of that chamber. The material transport maintains (15) the pressure difference between the filtration unit (10) and the chamber (20). Subsequently, the depressurized solid phase material can be conveyed to other equipment for drying or other processing.

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.
