摘要： A separation conveyor (10) for separating a mass or slurry of different sized particles is provided. The separation conveyor includes a filter belt (12) including a feed side for receiving the mass or slurry and a filtrate side. The separation conveyor further includes a conveyor assembly (16) for conveying the filter belt, an overhead spray array (28) for spraying fluid downwards onto the slurry as it travels on the filter belt, and a lower spray array (30) for spraying fluid upwards against an underside of the belt. The upper and lower spray arrays are arranged in combination to assist in promoting separation of oversized particles on the feed side of the belt and undersized particles on the filtrate side of the belt.

摘要： A process is disclosed that relates to the recovery of a metal catalyst from an oxidizer purge stream produced in the synthesis of carboxylic acid, typically terephthalic. More particularly, the process involves recovery of a metal catalyst from an oxidizer purge stream through the use of a pressure filter, the combining of water with a mother liquor to recover the metal catalyst and then subjecting an aqueous mixture so formed to a single stage extraction with an extraction solvent to produce an extract stream comprising organic impurities and a raffinate stream comprising the metal catalyst.

摘要： A precoat renewal system for a filter, such as a disc filter. The renewal system includes a plurality of nozzles coupled to spray piping and valving with each nozzle being positioned for spraying an area of one side of a disc. The nozzles and at least a portion of the spray piping is movable such that the nozzles may be displaced relative to the discs. The nozzles and piping are arranged in groups or zones with each zone covering a specified percentage of the discs in the filter and each zone representing about 40 % or less of the surface area of the filter media of the discs in the filter. Each zone is configured such that high pressure fluid may be supplied to that particular zone for removal of a precoat layer on the disc. The system may be configured so that other zones may be concurrently washed with a lower pressure fluid. The zones may be sequentially or otherwise segmentally provided with high pressure fluid until the precoat layers of each respective zone have been removed and renewed. A filter system and a method of treating a precoat layer on a disc-type filter including a plurality of filter discs are also disclosed.

摘要： A method and an apparatus for treating pulp with a treatment agent for simultaneous displacement and thickening, in which the pulp is fed into a space (6) in order to form a layer on the perforated casing (5) of a rotating drum (3). According to the invention, the treatment agent is also fed into the space (6) in order to form a continuous layer (22) of treatment agent up against the mobile pulp layer (20). The displacement and thickening are carried out continuously at a mechanical pressure on the pulp layer (20) which is less than 100 kPa, and for the most part using the treatment agent. The quantity of liquid which is displaced through the casing (5) per unit of time exceeds the quantity of treatment agent which is supplied. A distribution channel for the treatment agent is designed and arranged in association with the space (6) in such a way that the layer of treatment agent is formed and maintained in free contact with the pulp layer.

摘要： The present invention relates to a method and an apparatus for cleaning a filter drum or a cylinder used for thickening lime mud in which filter drum lime mud is thickened on a filtering layer of lime mud formed on the surface of a filter drum partially immersed in a vat containing lime mud. It is characteristic of the method of the invention that, before the lime mud cake is removed with a scraper from the surface of the precoat layer, a strip of lime mud is detached from the thickened lime mud layer with at least one liquid jet of low pressure movable in the longitudinal direction of the drum. It is characteristic of the apparatus of the invention that at least one nozzle (36, 38) is located in the rotational direction of the drum prior to the scraper removing lime mud cake and that the apparatus comprises, in addition to said at least one nozzle (36, 38), a jet nozzle (34) for making the precoat layer thinner.

摘要： In a process for mechanically dehumidifying a filter cake, differential pressure causes a treatment fluid to flow through the filter cake. Pressure and temperature on the side of the filter cake which faces the filter surface are set in such a manner that the treatment fluid is present there in its liquid phase, whereas pressure and temperature on the side of the filter cake opposite to the filter surface are set in such a manner that the treatment fluid is present on that side in its gaseous phase.

摘要：　従来、減圧回転濾過機を用いて吸引濾過、結晶洗浄、脱液工程を経て、晶析スラリーから結晶を分離回収されるが、洗浄工程において洗浄液の吸引により、濾過液あるいは洗浄液の溶媒の一部が蒸発および降温して濾布の網目上に溶質が析出してくる。そのため、濾布の網目に結晶の微細粒子が目詰まりし、吸引濾過による濾過（結晶粒子）層の形成が困難になり、また、洗浄液の通過も不充分となって連続濾過・洗浄の継続が出来なくなる。本発明は、転濾過法において、濾布の目詰まりを抑え、長期間連続して濾過・洗浄が継続できるようにすることを目的とする。　洗浄液を加熱器で加熱し、少なくとも蒸気の発生する温度（圧力）となるまで過熱し、洗浄工程で濾過機内の洗浄域に発生蒸気の伴った混相流として洗浄液を供給することにより、濾布網目上に微細結晶の目詰まりするのを抑えた。そして洗浄溶剤として１２０°C以上、好ましくは１３０°C以上、さらに好ましくは１４０°C以上に過熱した酢酸を用いる。また、洗浄用溶媒を好ましくは約７％以上の蒸気発生となる温度に、より好ましくは約14％以上の蒸気発生となる温度に過熱する。
摘要翻译：在现有技术中，通过使用真空旋转过滤机，将结晶从结晶浆液中分离回收，进行吸滤，洗涤和除液步骤。在洗涤步骤中，将滤液或洗涤液的溶剂的一部分蒸发并通过洗涤液的抽吸冷却，从而在所用的滤布网上引起溶质结晶。因此，滤布的网状物被微晶粒堵塞，因此通过抽滤形成过滤（晶粒）层变得困难。此外，洗涤液的通过将变得不令人满意，从而导致连续的过滤/洗涤的继续是不可行的。因此，在旋转过滤方法中，为了抑制滤布的堵塞，延长过滤/洗涤的持续性。已经通过使用加热器加热洗涤液以抑制过滤网上的微晶堵塞，从而达到过热至少至少蒸发产生的温度（压力），并将洗涤液作为混合相流动在洗涤步骤中，通过产生的蒸汽夹带在过滤机内的洗涤区域。作为洗涤溶剂，使用过氧化为120℃以上，优选为130℃以上，更优选为140℃以上的乙酸。洗涤溶剂过热至优选温度约7％或更多蒸气产生，更优选该温度约14％或更多蒸气产生。

摘要： A filter assembly includes a tank and a filter drum rotatably disposed inside the tank. The drum has an inner surface and an outer surface and is provided long the outer surface with a plurality of recessed compartments or cells, each of the compartments being provided with a filter element. A pressure let-down valve is disposed in the tank, the pressure let-down valve communicating sequentially with the compartments or cells during rotation of the drum, to draw off an overpressure in the compartments or cells. In addition, a blowback valve is disposed in the tank downstream of the pressure let-down valve as defined by a direction of rotation of the drum. The blowback valve communicates sequentially with the compartments or cells during rotation of the drum after the compartments or cells have passed the pressure let-down valve. This apparatus enables discharge of solids from the compartments or cells at atmospheric or ambient pressure.
