Abstract
The utility model relates to an internal-pressure type hollow fiber membrane assembly. The utility model comprises hollow fiber bundles, porous distributors, a liquid collecting porous central tube and a pressure bearing outer shell, wherein each porous distributor is provided with a central connecting opening, the porous distributors are arranged at both ends of the liquid collecting porous central tube, the hollow fiber bundles are arranged in the porous distributors and fiber arranged at both ends of a membrane assembly and the porous distributors are bound and fixed in the pressure bearing outer shell. The utility model is used for filtering or purifying liquid. The utility model is particularly used in pressure type assemblies which use hollow fiber as filtering materials. The utility model is especially applicable to the dead end filtering mode and the cross flow circulating filtering mode.
Description
Technical field
The utility model relates to a kind of device to liquid filtering or purification, relates in particular to a kind of realization and sees through liquid discharging smoothness, no dead angle, backwash efficient height, the inner pressed hollow fiber film assembly that strainability is stable.
Background technology
At present, doughnut has been widely used in filtration or the purified treatment to water or liquid.Use doughnut mainly to construct as the assembly of filtering material and comprise pressure resistant vessel, hollow fiber bundle, the hollow fiber bundle two ends are fixed.Former water in the container becomes water purification through the micropore permeation of hollow-fibre membrane under the certain pressure effect.In the use, materials such as the colloid in the former water, floating particulate constantly concentrate on the doughnut surface, cause efficient to reduce, and therefore, need clean.
Resistance is arranged and have the dead angle because the hollow fiber film assembly of press operation pattern exists through the liquid discharging in being used for, backwash liquor is bigger to the impact of film when carrying out backwash operation, cause the damage of film easily, particularly when equipment scale is big, backwash effect is difficult to reach ideal state, thereby causes reduce the service life of film.
The utility model content
Technical problem underlying to be solved in the utility model is, overcomes the defective that existing technology exists, and a kind of new inner pressed hollow fiber film assembly is provided, and it is smooth to realize seeing through the liquid discharging, no dead angle, and backwash efficient height, strainability is stable.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of inner pressed hollow fiber film assembly, the porous distributor, liquid collecting porous central tube and the bearing shell that comprise hollow fiber bundle, band center connector, the porous distributor places the two ends of liquid collecting porous central tube, hollow fiber bundle is placed in the porous distributor, and membrane module two ends fiber and porous distributor bonding also are fixed in the bearing shell.
Bearing shell is connected together by the arc snap ring of fast-assembling by housing and two ends end socket and constitutes.
End socket comprises the feed liquid inlet and sees through the liquid outlet that the end socket body has the tube connector that inserts porous distributor center connector.
The porous distributor of band center connector is made of radial distribution grid, is furnished with pod apertures or guiding gutter on the distribution grid, and there is the center connector at the position therebetween, connects the liquid collecting porous central tube.
In the work, feed liquid enters from the inner chamber of hollow-fibre membrane, through the hole of inner surface through film, sees through liquid and evenly flows out through distributor and central tube, has realized the isolated by filtration process of feed liquid.
It is smooth that the utility model sees through the liquid discharging, no dead angle, and backwash efficient height has improved the operation and the cleaning efficiency of film, has reduced the impact of backwash liquor to film, the service life of prolongation film.This assembly is suitable for dead-end filtration pattern and cross-flow filtration pattern.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is an overall construction drawing.
Fig. 2 is the vertical view of distributor,
Fig. 3 is the distributor profile.
The specific embodiment
As shown in Figure 1, a kind of inner pressed hollow fiber film assembly, it comprises porous distributor 7, liquid collecting porous central tube 12 and the bearing shell 9 of hollow fiber bundle 10, band center connector.Porous distributor 7 places the two ends of liquid collecting porous central tube 12, hollow fiber bundle 10 is placed in the porous distributor 7, membrane module two ends fiber and porous distributor 7 bondings also are fixed in the bearing shell 9, and bearing shell 9 is adopted the arc snap ring 6 of fast-assembling to connect together and locks by O-sealing ring 5 with two ends end socket 2 by housing 11 and constitutes.Membrane module sees through liquid outlet 1 and inserts the porous distributor center connector 13 that has 8 sealings of O-sealing ring by the tube connector 3 that the end socket body has.
As Fig. 2, shown in Figure 3, porous distributor 7 is made of radial distribution grid 14, and distribution grid quantity is 4 to 16, is distributed with pod apertures or guiding gutter 15 on the distribution grid, there is center connector 13 at the position therebetween, connector 13 be used to the to peg graft tube connector 3 of liquid collecting porous central tube 12 and end socket.The liquid collecting porous central tube of this porous distributor and grafting is used for collect seeing through liquid and transport membrane assembly counter-flushing liquid equably.
Feed liquid evenly flows into hollow fiber cavity by membrane module import 4 in the end socket chamber, behind the doughnut membrane filtration, see through liquid and evenly compile through porous distributor 7 and liquid collecting porous central tube 12, sees through liquid outlet 1 from end socket central authorities and flows out.
