Abstract
The invention provides a flat sheet membrane filter component. A spacing seal ring is arranged between two adjacent filter membrane bags and sleeves a liquid trap; a spacing strip is also arranged between two adjacent filter membrane bags and is arranged at the edges of the filter membrane bags; the filter membrane bags are spaced by using the seal ring and the spacing strip; since the distance between two adjacent filter membrane bags is increased, the filter component can be used for filtering liquid with high suspension content; besides, a plurality of ribs which protrude along the diameter direction of the liquid trap are uniformly distributed on the circumference of the liquid trap; the drainage area of the liquid trap is increased, further the filter speed of the filter component is improved and the operation cost of the filter component is reduced.
Description
Technical field
The present invention relates to a kind of Flat Membrane filter assemblies.
Background technology
Flat membrane ultrafiltration or micro-filtration filtration system have a wide range of applications in filtration and separation field, and its main type of service has rolled membrane module and plate type membrane component; Rolled membrane module is by Flat Membrane bag, cross-flow net volume on intermediate collection pipe, and the impurity in water body is retained by film, and filtered solution is flow in intermediate collection pipe by the graticule mesh in film bag, and is derived by intermediate collection pipe; Rolled membrane module generally adopts cross-flow filtration, and its advantage is that loading density is high, and floor space is little; Plate type membrane component is stacked in successively on filtered fluid collecting board and deflector by Flat Membrane filter disc, and sealed by sealing ring, the liquid after filtration is collected in filtered fluid collecting board, and is derived by tubule; Filtering also is adopt cross-flow filtration, and the advantage of conventional panel film is that every sheet film can be changed, and the expense that film is changed is lower.
Traditional plate type membrane component and rolled membrane module are all adopt cross-flow filtration, and need cross-flow pump to run continuously, the key benefit of cross-flow filtration is that of avoiding the gathering of impurity screening on film surface, alleviates the pollution of film; But conventional panel film but has a very large restriction when cross-flow, large or too much impurity can not be had in fluid to be filtered exactly, because these large or too much impurity are very easy to block the cross-flow graticule mesh that thickness is no more than 2mm, causing finally cannot cross-flow filtration.
In some filtration art, fluid to be filtered often has a lot of impurity, such as, activated sludge in oxygen consumption biochemistry pool, the cooling fluid in machined, the salt refining filtration etc. of chlor-alkali industry, cannot directly filter with conventional spiral wound and plate-type hyperfiltration; In order to realize conventional plate-type hyperfiltration and wound membrane filtration, fluid to be filtered has to pass through complicated pre-filtering, and be equipped with special wash cycles pipeline, valve etc., total system cost is very high.
Another solution adopts tubular membrane, tubular membrane due to inner passage larger, can adapt to the filtering flow of high impurity content, tubular membrane is also adopt external cross-flow with pressure to run, and its advantage is that film-strength is high, flux is large, but due to high speed cross-flow, high-voltage operation, energy consumption is very high, make its application surface very narrow, its high cost is also weak point simultaneously.
