Description
Technical field
The utility model relates to a kind of milipore filter, particularly a kind of horizontal hollow fiber ultrafiltration membrane.
Background technology
Along with social development, problem of environmental pollution more and more receives everybody concern.The continuous discharge of industrial pollution, sanitary sewage has produced huge threat to water resource, and shortage of water resources problem is constantly outstanding.For realizing recycling of water resource, the advantage of membrane technology in wastewater treatment constantly manifests, and the reduction ability of polluting is improved constantly.Hollow fiber ultrafiltration membrane is processed at middle low concentration wastewater, be widely used in advanced treatment of wastewater, mainly comprises the fields such as drinking water water supply terminal, surface water processing, Seawater Treatment, reusing sewage.
At present hollow fiber ultrafiltration membrane normally film and putamina be integrated, adopt vertical mounting means, during film replacing, need integral replacing.Filter type adopts external-compression type more, external-compression type filters be former water through pressure differential radially ecto-entad penetrate hollow-fibre membrane and become through liquid, the material of holding back collects in the outside of film.This mode easily causes film surface water stream skewness, produces bias current, and product water side dead angle is more, and the contaminant accumulation of holding back is between film silk and putamina, more obvious at membrane module two ends.After long-play, the pollutant that backwash and cleaning can not be held back dead angle is removed, and membrane module two ends produce dirty stifled, directly cause the decline of membrane flux; External-compression type film main material is PVDF(non-polar material), the filming performance of this material own is poor, and film silk is soft, is non-hydrophilic material, and antifouling property is poor, is difficult for making small-bore filter membrane, and it is poor that membrane aperture distributes, and film silk is easily broken.
Summary of the invention
For addressing the above problem, provide a kind of horizontal hollow fiber ultrafiltration membrane.
The purpose of this utility model realizes in the following manner: horizontal hollow fiber ultrafiltration membrane of the present utility model, by membrane module, by adapter, be composed in series, described membrane module comprise the guiding subassembly in cylindric putamina, putamina and be filled in putamina and guiding subassembly between film silk; Described guiding subassembly comprises and is vertically set on putamina inwall, the deflector extending to putamina axis direction and is stuck in the mozzle between deflector; Described mozzle and described deflector surround the central tube with putamina coaxial line; Described deflector number is 4 ~ 20, and is evenly distributed on putamina inwall; Sewage, through pressure-driven, enters film silk and mozzle simultaneously and filters and shunt, and filtered fluid is pooled to central tube through deflector, and the membrane module that mozzle is guided to next series connection by another part sewage carries out filtration and the shunting of a new round.
Described adapter is arranged on the central tube of two series connection milipore filter inside, along central tube inwall, arranges a circle.
Described film silk adopts long-chain high molecular weight hydrophilic PS membrane material, has V shaped hole structure.
Described deflector is that little skewback is piled up the corrugated plating forming.
Described mozzle cross section is the isosceles trapezoidal structure of going to the bottom as outer convex, between two waists and deflector, by glue sealing, is connected, and upper base and deflector elongated end surround central tube.
Between described adapter and membrane module, be tightly connected.
With respect to prior art, the utlity model has following beneficial effect: 1, the accessory such as adapter of the present utility model, central tube, mozzle designs by mechanical analysis, adopt rational pressure-resistance structure, can bear elevated pressures, diversion Design can play the effect of the pressure between reasonable distribution water inlet and balance film and film by water inlet water conservancy diversion in the membrane module except first film, and the filter efficiency of the film that assurance is cascaded is consistent, pressure distribution is even, there will not be the faults such as film silk breakage.2, membrane module needs to be placed in pressure vessel in use, these films arranged in series in pressure vessel, connects by adapter, and deflector is divided into several regions by the film silk in every film, to obtain best fluidised form, be particularly advantageous in backwash and chemistry reinforcement backwash.3, the material that adopts inner pressed filter type to guarantee that tunicle is held back is very easy to strengthen backwash by backwash or chemistry and removes, and guarantee that water inlet can contact with the outer surface of film, thereby assurance dirt can not piled up between film silk.
