摘要:
A filter system for use in a three-phase slurry reactor is provided. The filter system comprises one or more bundles of a plurality of filter elements for separating liquid from a mixture of liquid and solids contained in the reactor. Each filter bundle is connected to a product transfer conduit transporting separated liquid to a location outside of and downstream from the reactor. The transfer conduit is provided with means for backflushing the filter bundle and guard filter means.

The present invention relates to a filter candle for a precoated filter for filtering and/or stabilizing fluids, especially beer, the filter candle comprising a tubular filter body that is formed from a spirally wound wire, with gaps being provided between the wire windings as fluid passages. To improve the adhesion of the precoated filter in such a filter candle, it is intended according to the invention that the surface of the wound wire that rests against the exterior of the filter body is inclined by an angle null relative to the longitudinal axis of the filter candle.

A removable filter for separating and filtering slurry liquid from solid particles includes one or more filter sections connected by a filtrate conduit. Each section comprises a plurality of vertical, hollow, sintered metal filter elements horizontally arranged across a manifold connected to a hollow filtrate conduit. The sections are vertically stacked and connected by the conduit(s) to form the filter which is removably secured in the slurry by means which permit it to be removed vertically up and out of the top of the reactor. This filter has a high surface area to volume ratio and is useful for removing the liquid hydrocarbon products from a slurry hydrocarbon synthesis reactor and can easily be replaced without having to drain out the slurry.

The invention relates to medicament excipient particles which are suitable for tissue-specific application of a medicament, especially to the central nervous system (CNS). The invention particles can be loaded with or be free pf the active substance. At least one detection protein is bonded to the particle surface or alternatively, the particle surface is modified in such a way that a detection protein bonds with it on contact.

Apparatus is provided for filtering particulate matter from a fluid flow pumped from a coolant pool for a nuclear reactor. The apparatus comprises a large vessel with an interior chamber in which is rotatably supported a turntable in the form of a rigid basket-like support structure on which a large number of disposable filter cartridges are removably secured. Part of the turntable is a manifold assembly for distributing contaminated fluid received from a central conduit to the inlet side of the filter cartridges in the chamber. The vessel serves as a containment for coolant processed through the filters whereby the cleansed coolant may be conducted outwardly from the vessel through an outlet port and piped back to the pool of origin. Gate means are provided on the vessel in the form of normally closed ball valves which allow, during shut-down of the apparatus, extension, into and through the vessel, of tools to manipulate the turntable within the vessel and to accomplish filter cartridge replacement.
摘要:
A filtration apparatus having one or more upright tubular filter elements having a surface coated with a pre-coat layer of a filter aid through which a liquid is filtered. Different from conventional apparatuses, the filter element of the present invention is provided with a gas exhaust tube or liquid drain tube connected to the upper or lower part of the filter element, respectively. By virtue of this means, the liquid used for forming the pre-coat layer as the suspension medium can be completely discharged out of the apparatus prior to introduction of the liquid to be filtered so that the liquid in the apparatus can be switched from the pre-coat forming liquid to the filtered liquid without producing a mixture thereof, and without causing defects in the pre-coat layer.
摘要:
Slurry to be densified by removal of water is passed into an inlet of a housing, through the housing, and out an outlet. Inside the housing are a plurality of elongated hollow filter elements, which extend in the direction of flow of the slurry. Water in the slurry passes through the walls of and into the interiors of the hollow filter elements, as the slurry flows along the lengths of the filter elements. The cross-sectional area of the flow space for the slurry, defined between the exterior surfaces of the filter elements and the interior wall of the housing, decreases as one proceeds along the lengths of the filter elements. As a result, the flow speed of the slurry does not decrease proceeding in the flow direction, but instead is maintained at least substantially constant, or is even caused to increase (accelerating flow). Accordingly, the densified slurry flowing along the exterior surfaces of the filter elements, because its flow speed is constant or even increasing instead of decreasing can wash away solid particles which would otherwise tend to accumulate on the exterior surfaces of the filter elements.

A regenerative filter that includes a filter housing having inlet and outlet zones; a fluid path provided between the inlet and outlet zones; a plurality of filter elements each having an outer surface filter media applied thereto and functioning to filter particulate or contaminants from the fluid path; and a tube sheet that is supported across the filter housing, that is disposed just before the outlet zone and that provides the support for the plurality of filter elements. The plurality of filter elements are disposed in an array and includes bridging members or elements that connect between adjacent filter elements, and that forms with the filter elements, a closed interstitial space between adjacent filter elements for liquid flow; a nanoscale barrier on interior surfaces, including that of the regenerative media itself, providing a mechanism to disrupt the cell wall of microscopic viruses and organisms.

A method and device for dewatering most liquid/solid solutions and slurries is described. A dewatering device having a dewatering pump in fluid communication with a filter rack with vertically arrayed filter elements that is carried by a container. To begin the dewatering process, the filter rack is lowered to the bottom of the container and the liquid/solid slurry is introduced. Next, the dewatering pump draws the liquid from the slurry into the filter rack and then to the pump. When dewatering efficiency decreases, the dewatering operation is momentarily stopped and the filter elements of the filter rack are backpulsed with air and raised to dislodge the filter cakes that have formed. The filter rack is then relowered and the dewatering operation continues. These steps of dewatering, backpulsing, raising the filter rack, and lowering filter rack are continued until the container is full of dewatered solids. Alternatively, the filter rack is affixed to the top of the container and the liquid/solid slurries are introduced until the container is mostly full. Next dewatering operations commence and continue until the container is full of dewatered solids.
摘要:
A filtering device includes a container having an inlet for introducing liquid to be treated, an annular multi-layered prepacked screen assembly provided in the container and having an outlet for treated liquid. The screen assembly includes three or more cylindrical screens having different diameters and being coexially disposed in the container with their axes extending vertically in the container. An annulus is formed between the respective cylindrical screens. Two or more different filter materials performing different filtering functions are filled one in each of the annuluses between the cylindrical screens.
