Description
Technical Field
The invention belongs to a hollow fiber membrane component. More particularly, the present invention relates to a removable hollow fiber membrane module structure.
Background
The hollow fiber membrane (hollow fiber membrane) is shaped like a fiber. The outer diameter of the hollow fiber is 0.4-2.0mm, the inner diameter is 0.3-1.4mm, micropores are distributed on the wall of the hollow fiber, the aperture is expressed by the molecular weight of the trapped substance, and the trapped molecular weight can reach thousands to hundreds of thousands. The hollow fiber membrane includes a mixed fiber ester microporous filter membrane, a cellulose nitrate filter membrane, a polyvinylidene fluoride filter membrane, a cellulose acetate filter membrane, a regenerated cellulose filter membrane, a polyamide filter membrane, a polytetrafluoroethylene filter membrane, a polyvinyl chloride filter membrane and the like. The hollow fiber membrane is commonly used for water treatment and is applied to the fields of production and domestic sewage treatment such as pharmacy, brewing, catering, chemical industry, municipal sewage recycling, hospital, community sewage recycling, paper making and the like. The membrane technology is adopted to separate pollutants from water molecules, so that precious water resources can be recycled, precious metal ions in the pollutants can be filtered, concentrated and recycled, the economic benefit is considerable, the occupied area is not occupied, energy is not consumed, units such as petrochemical industry, cashmere manufacturing, beverages, medicines, municipal sewage treatment and the like are applied in a large scale, the investment benefit is obvious, and the prospect is extremely wide. In addition, in recent years, the new energy industry of microalgae has been emerging, and the hollow fiber membrane is also applied to the algae liquid concentration process of the microalgae harvesting process.
The membrane module consists of a membrane shell, membrane threads/membrane bundles, a packaging part and an end cover, and the packaging method is to fix the hollow fiber membrane threads into the membrane shell through epoxy resin glue to play a role in sealing. For example, CN 105120987 a discloses a fiber membrane module, as shown in fig. 1: the membrane bundle of membrane filaments 41 is mounted inside the housing part 1, and the mould for forming the enclosure part 2 is covered at both ends of the housing part. A composition for forming the potting portion (e.g., epoxy resin, etc.) is injected into the mold to fill the gaps between the hollow fiber membranes, and then the composition is cured, thereby sealing both ends of the housing portion 1. After the mold is opened, the protruding end of the solidified potting portion is cut off to expose the end of the hollow fiber membrane bundle 4, and the both ends of the case portion 1 are covered with the cover portions 5 having the fluid inlet and outlet 51. An inlet 121 and an outlet 122 are provided in the housing 1. However, since the hollow fiber membrane filaments are made of a polymer material, they do not have a rigid property, and cannot be sealed by a rigid connection method such as a screw thread or a hoop. In the process of encapsulating the film filaments with the epoxy glue, it takes several days for the epoxy to completely dry, which consumes time. When the membrane is polluted or broken and can not be used, the whole membrane assembly including the membrane shell, the interface and the like is discarded. The membrane shell and the interface are reusable engineering materials, and the scrapping means the waste of the materials and possible environmental pollution.

In the following description, numerous specific details are provided to provide a thorough understanding of embodiments of the invention. One skilled in the relevant art will recognize, however, that the invention may be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the invention.
Example 1
Fig. 2 is a schematic diagram of a detachable hollow fiber membrane module according to a first embodiment of the present invention, which is a monofilament membrane module structure, and is generally used in a laboratory to test the filtration performance, the permeation pressure, the backwashing time, and other operating parameters of a certain hollow fiber membrane. The membrane shell 2 comprises two water producing ports, and a hollow fiber membrane filament 3 arranged inside the membrane shell 2, wherein a through hole is formed in the middle of the hollow fiber membrane filament 3, and the length of the through hole is greater than that of the membrane shell 2, so that the hollow fiber membrane filament 3 can extend out of the membrane shell 2; two ends of the membrane shell 2 are also provided with end covers 1. The hollow fiber membrane silk 3 is provided with a needle 4, the length of the needle 4 is about 1/2, the needle 4 is inserted into the through hole of the membrane silk 3, and the needle 4 is about 1/2 exposed outside the membrane silk 3. A hoop 5 is arranged at the position corresponding to the insertion of the needle 4 outside the hollow fiber membrane filaments 3, and the hoop 5 can directly and hermetically clamp the membrane filaments 3 and the needle 4, or the hoop 5 can also be used for hermetically clamping the membrane filaments 3 and the needle 4 by means of the end cover 1. The details are as follows:
the end cap 1 comprises two ends, a first end is the end combined with the membrane housing 2, and a second end is the end far away from the membrane housing 2. The first end of the membrane shell 2 is provided with an inner hole 11, the second end is provided with a needle head hole 12, the inner hole 11 penetrates through the needle head hole 12, and the needle head hole 12 is used for the needle head 4 to penetrate out, so the aperture of the needle head 12 (as shown in figure 2) is far smaller than that of the inner hole 11. The periphery of the hole wall of the inner hole 11 is provided with internal threads, two ends of the membrane shell 2 are respectively provided with a section of reducing part, and the outer surface of the reducing part is provided with external threads 22. Therefore, when the end cap 1 is screwed on the external thread 22 of the membrane shell 2 by the inner hole 11, the wall of the peripheral hole of the inner hole 11 presses the hoop 5, which is preferably an O-shaped ring, and the O-shaped ring is rotated and pressed by the wall of the inner hole 11 of the end cap 1 to be tightened continuously, so that the hollow fiber membrane wires 3 surrounded by the O-shaped ring and the needle 4 are tightly bound together. When the end cap 1 is screwed into place on the external thread 22 of the membrane housing 2, the O-ring is compressed between the end of the membrane housing 2 and the bottom of the internal bore 11 of the end cap 1.
Preferably, a sealing rubber gasket 6 is also installed in the inner hole 11 of the end cover 1. The sealing pad shown in fig. 4A is a circular sheet body gasket 6 without pinholes on the surface; or as shown in fig. 4B, a cylindrical gasket 6 can be arranged in the inner hole 11 of the end cover 1 and matched with the inner space of the inner hole 11 in shape. Thus, when the end 1 is screwed onto the external thread 22 of the membrane housing 2, the needle 4 pierces the sealing rubber pad 6 and penetrates into the needle hole 12. As shown in fig. 2, the outer end of the needle 4 is preferably designed to be a sharp inclined surface, which not only increases the liquid inlet area of the through hole of the hollow fiber membrane filament 3 (compensates for the liquid inlet amount error caused by the through hole in the middle of the needle 4 being smaller than the through hole in the middle of the hollow fiber membrane 3), but also can easily puncture the sealing rubber pad 6.
The second end of the end cap 1 may be provided with an assembly portion for connection with a component of another experimental or working device for connection of the membrane module with another device, so that the membrane module of the present invention may be assembled for use in an actual experiment or application. Because the needle head 4 is rigid, the hollow fiber membrane wires 3 can be assembled and fixed in a bundling mode, and the holes in the middle of the needle head 4 can still allow liquid to enter the middle of the hollow fiber membrane wires 3, so that the filtration and separation effects are realized through the micropores in the surfaces of the membrane wires 3. In the harvesting of microalgae, a hollow fiber membrane module is commonly used in the primary concentration process of algae liquid, the algae liquid enters through holes in the mesoporous fiber membrane filaments 3 from one end of the membrane module, water molecules continuously permeate from the inside of the membrane filaments 3 to the outside of the membrane filaments 3 and are collected in the membrane shell 2, water is obtained from a water producing port 21 of the membrane shell 2, and concentrated algae liquid is obtained from the other end of the membrane module and is introduced into a centrifugal device for further separating algae biomass.
Different hollow fiber membrane silk's material is different, the aperture size also is different, therefore its working parameter is also different, and the environment of using is different in addition, and the liquid that lets in is different, also has different working parameter. For this reason, a large number of bench tests are often required before a liquid is subjected to a filtration/concentration treatment. By adopting the detachable hollow fiber membrane module structure provided by the embodiment of the invention, epoxy resin is not needed for sealing, and the membrane shell 2, the end cover 1 and the like can be repeatedly used, so that the efficiency is improved, and the waste of materials is reduced.
Example 2
Fig. 3 is a schematic structural view of a detachable hollow fiber membrane module according to a second embodiment of the present invention. Example 2 differs from example 1 only in that, in example 2, the hollow fiber membrane filaments 3 contained in the membrane shell 2 are not single but multiple. For a membrane module requiring assembly of a plurality of membrane filaments 3, the membrane assembly structure is basically the same as that of example 1, except that before the hollow fiber membrane filaments 3 are plugged into the module 2, there is a membrane filament aligning step: a plurality of hollow fiber membrane filaments 3 are arranged side by side to form a membrane bundle, the cross section of the membrane bundle is preferably the same as the shape of the port of the membrane shell 2, then the membrane bundle is plugged into the membrane shell 2, and the two ends of the membrane bundle are exposed out of the membrane shell 2. Then, the needles 4 are inserted into both ends of each hollow fiber membrane filament, and the hoop 5 is bound outside the membrane filament bundle composed of the membrane filaments, wherein the hoop 5 is preferably an O-ring. Wherein, a plurality of membrane filaments 3 to be assembled can be bonded and orderly to form a membrane bundle (the corresponding position of the hoop 5 is not coated with glue, as shown in fig. 3, the shadow is coated with glue), or a plurality of hollow fiber membrane filaments 3 can be orderly formed into a membrane bundle by adopting other modes, but the working performance of the hollow fiber membrane filaments 3 is not influenced, that is, the liquid can not be extruded and narrowed through the through holes in the middle of the hollow fiber membrane filaments 3.
When the hollow fiber membrane wires 3 are multiple, the needle 4 punctures the sealing foot pad 6 and extends out of the needle hole 12 of the end cover 1. Wherein the inner diameter of the hollow fiber membrane filaments 3 is slightly larger than or equal to the outer diameter of the needle, whereby when the hoop 5 tightly binds the needle 4 and the membrane filaments 3 together, some of the membrane filaments 3 material is stacked and squeezed to further improve the sealing of the connection of the membrane filaments 3 and the needle 4.
For the membrane module of the plurality of hollow fiber membrane filaments 3, in addition to the assembly structure and method of embodiment 2, needles 4 may be inserted into both ends of each membrane filament 3 of the plurality of membrane filaments, and a hoop 5 may be used to hoop the needles 4 and the membrane filaments 3, wherein the hoop 5 is a plurality of small hoops, and the number of the small hoops is the same as that of the membrane filaments 3. Then obtaining a plurality of independent membrane filaments with two ends fixed with needles 4, then respectively installing the membrane filaments with two ends fixed with needles 4 into the membrane shell 2, then screwing the end cover 1, and penetrating the outer ends of the needles 4 into the needle holes 12 of the end cover 1.
While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
