Abstract:
The present invention relates to a filtering unit (1) for separating and filtering water contained in sludge waste. The filtering unit (1) is insertable within a tank (2) defining at least one collection compartment (200) of said sludge waste. The filtering unit (1) comprises a first filtering module (21) and a second filtering module (22) for filtering said water. The filtering unit (1) further comprises a circulation line (70) for transferring the water filtered by the first module (21) to the second module (22), and a collection line (80, 80A) to collect and convey the part of water also filtered by said second module (22). The filtering unit (1) further comprises a supporting frame (12) which supports the modules (21, 22). Such a frame (12) is either partially or completely insertable into the compartment (200) of the tank (2) through a manhole (114). Finally, the filtering unit (1) comprises connection means configured to form a connection between the frame (12) and the tank (2) so that said filtering modules (21, 22) are completely arranged within said compartment (200) upon such a connection.
Abstract:
A parallel flow filter-in-filter design for a filter system is provided. The filter-in-filter design provides two distinctly parallel or independent flow paths within a filter assembly in a single housing or shell. The filter assembly includes a first outer filter element radially spaced apart from a second inner filter element. A centertube and a funnel shaped passageway housed within the centertube are provided in a space between the first outer filter element and the second inner filter element. The centertube and funnel shaped passageway work in tandem to provide two distinct parallel or independent flow paths within the filter assembly. The funnel shaped passageway is provided generally below the second inner filter element within the centertube.
Abstract:
A hydroclone (10) having a tank (12) including a fluid inlet (14), a filtered fluid outlet (16), an effluent outlet (18), a process fluid outlet (20) and an inner peripheral wall (22) enclosing a plurality of vertically aligned chambers (24, 30, 32). In one embodiment the tank (12) includes three vertically aligned chambers including a vortex chamber (24) in fluid communication with the fluid inlet (14). A filter assembly (26) is located within the vortex chamber (24) and encloses a filtrate chamber (66). The vortex chamber (24) includes a fluid pathway (28) adapted for receiving incoming fluid and generating a vortex fluid flow about the filter assembly (26). The filtrate chamber (56) is in fluid communication with the filtered fluid outlet (16) such that fluid passing through the filter assembly (26) enters the filtrate chamber (56) and may exit the tank (12) by way of the filtered fluid outlet (16). An effluent separation chamber (30) is located below and in fluid communication with the vortex chamber (24) and is adapted for receiving unfiltered fluid from the vortex chamber (24). A process fluid chamber (32) is located below and in fluid communication with the effluent separation chamber (30) and is adapted for receiving a process fluid from the effluent separation chamber (30) wherein the process fluid chamber (32) is in fluid communication with the process fluid outlet (20) by which process fluid may exit the tank (12). A vortex flow barrier (34) is located between the vortex and effluent separation chambers (24, 30) and disrupts vortex fluid flow from the vortex chamber (24) to the effluent separation chamber (30). An effluent barrier (36) is located below the effluent separation chamber (30) and directs fluid flow from the effluent separation chamber (30) to the process fluid outlet (20), and wherein the effluent barrier (36) further comprises a centrally located effluent opening (38) in fluid communication with the effluent outlet (18) by which effluent may exit the tank (12). A hydrodone (10) having a tank (12) induding a fluid inlet (14), a filtered fluid outlet (16), an effluent outlet (18), a process fluid outlet (20) and an inner peripheral wall (22) endosing a plurality of vertically aligned chambers (24, 30, 32). In one embodiment the tank (12) includes three vertically aligned chambers including a vortex chamber (24) in fluid communication with the fluid inlet (14). A filter assembly (26) is located within the vortex chamber (24) and endoses a filtrate chamber (66). The vortex chamber (24) indudes a fluid pathway (28) adapted for receiving incoming fluid and generating a vortex fluid flow about the filter assembly (26).
Abstract:
Die Erfindung betrifft eine Vorrichtung zum Filtern von Fluid-Feststoff-Gemischen (10), vorzugweise Suspensionen, mit einem entlang einer Achse (1) sich erstreckenden Gehäuse (2), in dem Filterelemente (23) angeordnet sind, deren Filterflächen (24) vom Fluid-Feststoff-Gemisch (10) überströmt sind, und mit einem in das Gehäuse (2) mündenden Einlauf (11, 11 '), mit dem das Gehäuse (2) mit dem Fluid-Feststoff-Gemisch (10) beschickbar ist, und mit einem ersten aus dem Gehäuse (2) mündenden Auslauf für das Retentat und mit einem zweiten Auslauf (32) für den Abzug des Filtrats (33). Der Einlauf (11, 11 ') umfasst einen tangential verlaufenden Einströmspalt (12, 12'), der sich zumindest über den den Filterelementen (23) radial gegenüberliegenden axialen Längsabschnitt des Gehäuses (2) erstreckt. Die Erfindung umfasst ferner ein Filterelement für eine solche Vorrichtung, das sich aus mehreren Filtersegmenten zusammensetzt.
Abstract:
The invention relates to a module of units (1) for an internal combustion engine, comprising, as first unit, a device (2), for separating out contaminants from the lubricating oil in the internal combustion engine, whereby the device (2) has a filter insert (21), a free-jet centrifuge (22), driven by means of the flowing lubricating oil, at least one supply channel (23) for lubricating oil to be purified, an outlet channel (24), for lubricating oil which has flowed through the filter insert (21) and a return channel (25) for oil which has flowed through the centrifuge (22), whereby the centrifuge (22) is arranged above the filter insert (21) in a common housing (20). The novel module of units is characterised in that the module (1) comprises a further unit (3) of the internal combustion engine, the further unit (3), comprising a housing (30) which is detachably connected to the housing (20) of the device (2) and that both housings (20, 30) form the return channel (25) between housing regions (26, 36), which contact each other in a sealing manner.
Abstract:
A method for pre-coating filter media of a filter (108) may comprise the step of performing a separation on a first portion of slurry (102) to be dewatered by the filter (108). A coarse stream (102c) may be produced from the separation and at least a portion of the coarse stream (102c) may be provided to the filter (108) to pre-coat the filter media of the filter (108). The coarse stream (102c) or a refined coarse stream (102f) may be provided to the filter (108) before providing a second portion of the slurry (102) to the filter (108). Filtration systems (101) and methods may allow pre-coating techniques without necessarily using a consumable pre-coat media (e.g., diatomaceous earth).
