According to a first aspect, the disc filter includes a vessel comprising an inlet positioned in a wall of the vessel, the inlet introducing a fiber suspension into the vessel. The disc filter further includes a rotor shaft comprising a shaft axis of rotation positioned in a shaft plane, wherein the shaft plane is a horizontal plane. At least one filter element may be coupled to the rotor shaft. At least one injector may be positioned in the wall of the vessel, the at least one injector introducing a secondary flow of liquid into the vessel. The at least one injector may be located in the wall of the vessel at an injector elevation angle on that is greater than -44 degrees and less than or equal to +22 degrees relative to the shaft plane.

Eine Filtereinrichtung (1) zum Klären von verschmutzten Flüssigkeiten, insbesondere von Abwasser, besteht aus mehreren voneinander beabstandeten Filterelementen (4), die Filtermodule (3) bilden und kreis- oder polygonförmig in einem, die ungeklärte Flüssigkeit enthaltenden Behälter (2) drehbar angeordnet sind. Die kreis- oder polygonförmig angeordneten Filtermodule (3) bilden einen Hohlraum (14), der mit dem Behälter (2) über eine Ansaugöffnung (12) verbunden ist. An und/ oder in dem Hohlraum (14) ist eine Reinigungseinrichtung zur Reinigung der Filterelemente (4) mit Spülluft angeordnet. Bei einem Verfahren zum Reinigen von Filterelementen (4) einer Filtereinrichtung (1) erfolgt während des Betriebs eine Abreinigung rotierender Filterelemente (4) durch Spülluft. Die Filterelemente (4) sind hierbei voneinander beabstandet kreis- oder polygonförmig in einem, die ungeklärte Flüssigkeit enthaltenden Behälter (2) drehbar angeordnet und bilden einen Hohlraum (14).

摘要:
The present disclosure provides for a continuous rotary plate filter apparatus and a method of using the apparatus to separate slurries into liquids and solids. The methods and apparatus are useful for the production of fine chemicals and pharmaceuticals, particularly using Integrated Continuous Manufacturing (ICM), but can also be integrated with other manufacturing processes, such as batch and semi-continuous processes.
摘要:
An apparatus for performing an operation on a fluid material to separate liquid from solid matter within the fluid material The apparatus comprises a belt structure movable along a path. The belt structure comprises a belt portion adapted to be assembled into a movable tubular structure within which at least part of the operation is to be performed. The tubular structure is permeable to liquid for separation of liquid from solid matter within the fluid material. The tubular structure is continuously assembled at one end thereof and continuously disassembled at another end thereof during movement of the belt structure. The path includes a descending portion along which the assembled tubular structure passes, the descending portion being inclined whereby at least some of the solid matter within fluid material in the tubular structure is caused to move downwardly along the descending portion under the influence of gravity to facilitate cleaning of the permeable tubular structure.
摘要:
A method of continuous filtration of contaminants from a contaminated viscous fluid, the method may include: pumping the contaminated viscous fluid between a non-perforated surface and a perforated surface disposed substantially parallel to each other at a defined gap; moving the non- perforated surface and/or the perforated surface with respect to each other at a defined relative speed; providing pressure to the contaminated viscous fluid; and regulating the relative speed and the pressure so that a layer of the contaminated viscous fluid adjacent to the perforated surface is forced to flow through perforation apertures of the perforated surface to other side of the perforated surface, while contaminants having a size larger than a size of the perforation apertures are forced to flow in the direction substantially parallel to the relative speed.
摘要:
Vorrichtung zum kontinuierlichen Filtrieren einer Schlammsuspension Es wird eine Vorrichtung zum kontinuierlichen Filtrieren einer Schlammsuspension mit einer in einem Gehäuse (1) drehbar gelagerten Hohlwelle (2), die mit dem von einer Filtermembran (5) umgebenen Innenraum (6) eines scheibenförmigen, radial von der Hohlwelle (2) abstehenden Filterkörpers (3) zum Ableiten eines Filtrates strömungsverbunden ist, beschrieben. Um unabhängig vom Feststoffgehalt der zu filtrierenden Schlammsuspension, der Filterkuchendicke und der Filtrationsdauer einen höheren Durchsatz des Filtrats zu ermöglichen, wird vorgeschlagen, dass der Radius (r) des Filterkörpers (3) in Umfangsrichtung von einem Niederdruckradius ri zu einem Hochdruckradius rh hin zur Verringerung des freien Gehäusequerschnitts zunimmt.
