Background
Along with the rapid development of industry and the continuous upgrading of industry technology, the application of inorganic ceramic membrane separation technology in the aspects of organic solvent recovery, domestic and industrial sewage treatment, drinking water and the like is receiving more and more attention. The ceramic hollow fiber membrane is used as a new generation inorganic ceramic membrane element product, and has gradually become the adopted configuration of an inorganic ultrafiltration membrane, a ceramic nanofiltration membrane, a molecular sieve membrane and the like due to higher filling density and permeation flux.
Chinese patent CN101108310A discloses a hollow fiber ceramic membrane element and a component thereof, which are mainly used for microfiltration and ultrafiltration filtration systems, and the hollow fiber ceramic membrane is tightly packaged together, so that the internal mass transfer resistance is increased, the utilization rate of the hollow fiber membrane is obviously reduced, and the flux is smaller. On the other hand, the ceramic nanofiltration membrane mainly adopts a single-tube and multi-channel structural type configuration, has high cost and small filling area, and prevents the application range of the ceramic nanofiltration membrane to a certain extent.
It is worth noting that the molecular sieve membrane has excellent performance in the aspect of organic solvent dehydration and outstanding energy conservation and emission reduction advantages, and is favored by people. After Germany and Japan, the industrial application is realized at the beginning of the 21 st century. So far, the organic solvent dehydration engine 100 has also been built. The current commercial molecular sieve membranes mainly comprise tubular and multi-channel molecular sieve membranes, and have low packing density, so that the investment cost of the membrane separation device is relatively high. Therefore, ceramic hollow fiber molecular sieve membranes have attracted extensive attention from researchers as a new generation of membrane elements. Chinese patent CN 101920170a discloses a high flux molecular sieve alcohol permeation membrane and a preparation method thereof, a hollow fiber carrier is spun by YSZ (yttrium stabilized zirconia) material, and an MFI molecular sieve membrane is prepared on the carrier. In a 5wt%/95wt% ethanol water system, the molecular sieve membrane permeation flux is as high as 7.4 kg/(h.m 2). Chinese patent CN 105879687A describes the hollow fiber ceramic membrane element and the membrane component, which realizes the modularization of the hollow fiber membrane. However, the membrane elements in the above patent are circular assemblies, the arrangement is relatively dense, and the hollow fiber membrane loading area and the fluid mass transfer efficiency between the tube bundles are improved, but the prominent advantages of the hollow fiber membrane elements are not fully shown. Therefore, the improvement of the membrane element configuration form and the membrane assembly composition mode provides a foundation for realizing the high packing density and high flux of the hollow fiber membrane assembly, and further expands the application field of the hollow fiber membrane element.

In the above structure, since the periphery of the hollow fiber membrane element 5 is regular polygon, when a plurality of hollow fiber membrane elements are adopted, a plurality of membrane elements can be installed in the same hollow fiber membrane module, and the polygons can be better matched with each other, so that the space position in the membrane module can be reasonably utilized. For example, as shown in the square structure of fig. 7, the space around the membrane element can be effectively utilized, and the shapes of the membrane elements can be mutually matched, so that the filling area can be effectively increased.
In some embodiments, the number of sides of the regular polygon is any integer from 3 to 20.
In some embodiments, the porous cover plate 1 and the porous substrate 3 are made of metal or ceramic materials.
In some embodiments, the number of cells on the porous cover plate 1 or the porous substrate 3 is 3 to 500.
In some embodiments, the sealing material 4 is an organic sealing agent or an inorganic sealing agent, preferably an inorganic sealing agent.
In some embodiments, the inorganic hollow fiber membranes 2 are between 1 and 150cm in length.
In some embodiments, the inorganic hollow fiber membrane 2 is made of one or two of Al 2O3, YSZ, mullite, metal, molecular sieve or graphene, and the outer diameter of the inorganic hollow fiber membrane 2 is 0.1-10 mm.
In some embodiments, the inorganic hollow fiber membrane 2 is a composite membrane composed of a hollow fiber homogeneous membrane or a hollow fiber support and a separation membrane layer.
In some embodiments, the inorganic hollow fiber membrane has between 1 and 20 channels.
In some embodiments, the sealing material 4 is coated on the outer surface of the porous cover plate 1, and seals off the channels of the hollow fiber membranes 2 located at the section of the porous cover plate 1. In this way, a membrane element in dead-end filtration mode can be manufactured.
In addition, as shown in fig. 6, a feed port a and a discharge port b are further provided on the membrane module housing 6, two ends of the membrane module housing 6 are respectively provided with a sealing head, and a vacuum port c and a liquid discharge port d are respectively provided on the sealing heads at the two ends.

The method for manufacturing the hollow fiber membrane module comprises the following steps:
Manufacturing a hollow fiber membrane element 5, installing the hollow fiber membrane element 5 in a membrane module shell 6, and sealing the periphery of a porous cover plate 1 and a porous substrate 3 on the hollow fiber membrane element 5 by using a sealing ring;
the hollow fiber membrane element 5 is produced by the steps of:
S1, respectively sleeving two ends of an inorganic hollow fiber membrane 2 into pore channels on a porous cover plate 1 and a porous substrate 3;

In one embodiment, the sealing ring is made of silica gel, fluorine gel, tetrafluoroethylene or graphite.
In another modified embodiment, as shown in fig. 9, when the inorganic hollow fiber membrane 3 is inserted into the pore canal 7 of the porous cover plate 1 or the porous substrate 3, since the diameter of the inorganic hollow fiber membrane 3 is thin, it is easily broken, if the membrane is broken and damaged due to improper force when the installation between the membrane and the pore canal is tight, and it is also easily caused that the sealant is not easily and well penetrated into the gap between the membrane and the pore canal, resulting in a problem of leakage once the raw material is pressurized during use. Therefore, the outer wall of the inorganic hollow fiber membrane 3 is in clearance fit with the pore canal 7, and a certain space is reserved between the inorganic hollow fiber membrane and the pore canal, so that the inorganic hollow fiber membrane can be prevented from being broken in the installation process and can be penetrated by sealant. However, after the space is reserved, the position between the hollow fiber membrane and the periphery of the pore canal is easy to be unstable, if one side of the inorganic hollow fiber membrane 3 is lapped on one side of the pore canal 3 and is contacted with the wall surface, when the sealing material 4 flows into the pore canal and is heated and solidified again, the two sides of the part of the hollow fiber membrane 2 inserted into the pore canal 7 are stressed unevenly in the process of solidifying the sealing material, and the problem of breakage easily occurs in the process of solidifying the sealing glue, therefore, before the inorganic hollow fiber membrane 2 is inserted into the pore canal 7, the outside of the inorganic hollow fiber membrane 2 is coated with the thermal shrinkage type temperature sensitive gel 8, because the temperature sensitive gel is in an expansion state at normal temperature and has certain elasticity, the inorganic hollow fiber membrane 2 can be well fixed in the pore canal 7, and the problem that one side of the inorganic hollow fiber membrane 2 is directly lapped on the inner wall of the pore canal 7 is avoided, and when the temperature of the sealing material is started to be solidified, the thermal shrinkage process is even, the sealing glue poured in the upper part can be infiltrated into the pore canal 7 evenly, the sealing glue can not infiltrate into the sealing glue at the pore canal 7, and the sealing glue can not volatilize at the temperature of the sealing glue is prevented from being even in the temperature of the middle of the temperature, and the thermal shrinkage element is not uniform, and the problem of volatilizing the ceramic glue can be completely burnt, and the sealing glue can be completely heated at the temperature-stable, and the ceramic glue can be completely heated at the temperature of the sealing membrane 2 is completely heated, and heated at the temperature after the temperature is well heated, and the temperature stable at the temperature is well heated.

The inorganic hollow fiber membrane 2 is a four-channel hollow fiber molecular sieve membrane, wherein the supporting layer is alpha-Al 2O3, and the separating layer is a NaA molecular sieve membrane. 113 hollow fiber molecular sieve membranes are inserted into the regular quadrilateral base pore canal at one end, the gap between the hollow fiber membranes and the base pore canal is sealed by a sealing material 4 (ceramic glue), the other end of the hollow fiber molecular sieve membrane is connected with a regular quadrilateral porous cover plate hole, and ceramic glue is coated on the outer surface of the cover plate, so that a dead-end type hollow fiber membrane element is manufactured, as shown in figure 2. After the manufacture is completed, the ceramic sealant is solidified after sintering.
And the cover plate ends of the 4 regular quadrilateral hollow fiber membrane elements are downwards placed in a square stainless steel shell, and the hollow fiber membranes are fixed in the square stainless steel shell in a sealing way to form the regular quadrilateral hollow fiber membrane assembly. Wherein, the hollow fiber membrane element is sealed with the stainless steel shell by a square tetrafluoro pad. The hollow fiber membrane module comprises a feed inlet, a discharge outlet and a liquid discharge outlet. The assembly shows better separation efficiency in the separation of ethanol and water.
