    摘要: 418,075. Filters. AKTIEBOLAGET KEMISKA PATENTER, Landskrona, Germany. July 31, 1933, No. 21486. Convention date, Sept. 6, 1932. [Class 46.] Filtering and washing of separated solid matter take place as an endless filter band, supported by an endless rubber or other elastic band, formed with apertures, passes horizontally over one or more suction boxes, with the smooth edges of which the carrier band makes tight contact. A second elastic and perforated or porous band may be arranged intermediate the filter band and the carrier band. The intermediate band or the carrier band may be ribbed or grooved. The Figure shows an arrangement comprising an elastic carrier band a having outwardly-turned edges, a filter band e, a suction box c, with draw-off connection 11 for filtrate and wash liquor, washliquor supply nozzles i , and a hopper k for supplying the material under treatment. The filter cloth, from which the cake is discharged as the cloth passes round the roller b is washed by water from nozzles f, or, if the cloth is longer than the band a, by a nozzle g. The suction box may be adjustable either vertically or horizontally. The suction box may also be divided into sections by transverse partitions which can be moved longitudinally or turned about axes. The space between the nozzles i and the band may be divided into sections by longitudinally and vertically adjustable partitions having flexible lower ends or provided with rollers at their lower ends.

    摘要: A filter device for filtering a suspension comprises at least one filter for continuous creation of a filter cake containing particles from the suspension; at least one dispensing device configured to apply at least one first wash liquid to the filter cake created by the at least one filter; and at least one steaming unit configured to steam the filter cake using steam, wherein the at least one dispensing device is integrated into a first process chamber and the at least one steaming unit is integrated into a second process chamber separated from the first process chamber by at least one partition wall. The at least one first wash liquid and a second wash liquid used for creating the steam may have boiling temperatures differing by at least 5° C.

    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 is provided. 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 are 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.
