Description

Technical Field

[0001] The present application relates to the technical field of membrane bioreactors, and in particular to a membrane assembly and a membrane group system. Background Art

[0002] In the past 30 years, membrane separation technology has rapidly developed into a practical high-tech in the fields of food, brewing, medicine, chemical industry, environmental protection, etc. due to its advantages such as convenient operation, compact equipment, safe process, and good separation effect. In sewage treatment, the membrane bioreactor (MBR) formed by the organic combination of membrane separation and biological process has some advantages that conventional sewage treatment processes cannot match, so this technology has shown good development prospects.

[0003] In water treatment such as water purification and sewage treatment, the industry has studied membrane materials with different filtration pore sizes, such as microfiltration, ultrafiltration, nanofiltration, reverse osmosis, etc., and used these membrane materials to separate solids from the treated water. In this process, the geometry of the membrane, or the way it is formed, is the key to determining the performance of the entire process. In addition, it is necessary to actually consider the way in which the monolithic membrane itself constitutes the membrane assembly. For example, the configuration of a monolithic membrane should have the following characteristics: a high ratio of membrane area to membrane assembly volume, a design that allows modular assembly, and a design that facilitates membrane cleaning. However, some of these characteristics are contradictory. For example, direct mechanical cleaning of the membrane is only possible when the relative membrane area is low. For example, a high ratio of membrane area to membrane assembly volume can be obtained by producing a narrow flow channel assembly, but this will also affect the cleaning method and the increase in turbulence.

In the description of the present application, unless otherwise specified, the meaning of "a plurality" is two or more.

[0036] In the description of the present application, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0037] In a first aspect, please refer to Figures 1 to 4, the present application provides a membrane module 100, which includes a membrane unit 10, a water collection box 20, and a connection unit 30. The membrane unit 10 includes a filtration unit 11 and a casting box 12. The casting box 12 is connected to both ends of the filtration unit 11 to fix the filtration unit 11. A receiving cavity 21 is formed in the water collection box 20, and the receiving cavity 21 is used to accommodate at least one casting box 12. The filtration unit 11 communicates with the receiving cavity 21, and a water production port 22 communicating with the receiving cavity 21 is provided at one end of the water collection box 20. The connection unit 30 is arranged at the other end of the water collection box 20. The connection unit 30 is used to connect the water collection box 20 to the membrane rack 201. The connection unit 30 includes a first connection portion (not shown) and a second connection portion (not shown), and the first connection portion and the second connection portion are arranged on the outer surface of the water collection box 20. The casting box 12 can fix both ends of the flexible filtration unit 11, thereby forming a membrane unit 10. The receiving cavity 21 of the water collection box 20 can accommodate at least one casting box 12. In this way, the water collection box 20 can install one or more membrane units 10, realizing the modular assembly of the membrane unit 10 in the water collection box 20. During actual use, multiple membrane units 10 can be installed in the water collection box 20 according to design requirements. In this way, in a water collection box 20 with the same volume, the present solution can cast a larger number of filtration units 11, improving the packing density of the filtration units 11. On the one hand, compared with the solution of arranging multiple water collection boxes 20 side by side, the present application proposes to install multiple membrane units 10 in one water collection box 20, which is more conducive to increasing the area of the membrane unit 10, thereby increasing the floor area ratio of the membrane module 100 and making the structure of the membrane module 100 more compact. On the other hand, since the area of the membrane unit 10 increases and the flux of the filtration unit 11 increases, this helps to increase the water production amount of the filtration unit 11 and improve the volume ratio of the membrane module 100.

[0038] By providing the first connection portion and the second connection portion to connect the water collection box 20 to the membrane rack 201, the contact area between the water collection box 20 and the membrane rack 201 can be increased, thereby improving the connection strength and installation stability of the water collection box 20. Even when multiple membrane units 10 are integrated in the water collection box 20, the stable connection between the water collection box 20 and the membrane rack 201 can still be ensured. By separately arranging the connection unit 30 and the water production port 22 at both ends of the water collection box 20, in this way, the fixing function and the water production function of the water collection box 20 can each play their independent roles, and there is no mutual influence between the connection unit 30 and the water production port 22, making the structure of the water collection box 20 more compact and improving the stability of the water collection box 20 during use.

[0039] It is understandable that the casting box 12 can fix the filter unit 11, but does not affect the filtered water passing through the filter unit 11 and entering the water collecting box 20. When the casting box 12 is fixed to the water collecting box 20, the filtered water collected by the filter unit 11 can be collected in the water collecting box 20 and discharged through the water outlet 22 of the water collecting box 20, thereby achieving the effect of sewage filtration. Optionally, the filter unit 11 includes microfiltration membrane filaments or ultrafiltration membrane filaments, and the filter unit 11 is cast in the casting box 12 along the height direction. The filter unit 11 is used to intercept impurities in the water, and the filtered water is transported to the outside through the water outlet 22 under pressure. Specifically, the filter unit 11 can be set as a TIPs, NIPs homogenizing membrane or a lining membrane, which will not be repeated here.

[0040] Optionally, the filter unit 11 is usually arranged vertically, and the filter unit 11 has an upper and lower end. Therefore, a casting box 12 is provided at both ends of the filter unit 11. Correspondingly, a water collecting box 20 can also be provided at both ends of the membrane unit 10. The water collecting box 20 located at the upper end can be suspended and connected to the membrane frame 201, and the water collecting box 20 located at the lower end can be fixedly connected to the bottom of the membrane frame 201.

[0041] Exemplarily, the first connecting part and the second connecting part can be configured as connecting structures such as buckle plates, connecting columns, slots, screw holes, etc. The first connecting part and the second connecting part can specifically adopt the same structure or different structures. The buckle plates and connecting columns will be used as examples for explanation below.

[0042] In some embodiments, the first connection portion includes a gusset plate 31, which is extended along a side away from the accommodating chamber 21, and the gusset plate 31 is used to be clamped on the membrane frame 201. By providing the gusset plate 31 and utilizing the clamping effect of the gusset plate 31 and the membrane frame 201, the water collecting box 20 can be fixed on the membrane frame 201. The connection method using the gusset plate 31 has the characteristics of simple structure and easy installation, which helps to improve the installation efficiency and fixing effect of the water collecting box 20. Optionally, the gusset plate 31 and the membrane frame 201 can be further fixed by a fixing structure such as bolts and rivets to improve the stability of the connection of the water collecting box 20.

[0043] For example, see Figure 7 and Figure 12, the membrane rack 201 includes a horizontally arranged mounting cross beam 2011 and vertically arranged support columns 2012. The space formed between the support columns 2012 and the mounting cross beam 2011 constitutes the framework of the membrane rack 201, and the space formed in the framework can be used to accommodate the membrane module 100. When the membrane module 100 is installed on the membrane rack 201, the buckle plate 31 can be snapped onto the mounting cross beam 2011. Connection holes can be opened at the top or side of the buckle plate 31, and corresponding connection holes are also provided on the mounting cross beam 2011 of the membrane rack 201. Bolts pass through the connection holes of the buckle plate 31 and the connection holes of the mounting cross beam 2011 simultaneously, thereby fixing the buckle plate 31 on the mounting cross beam 2011 and realizing the connection between the membrane module 100 and the membrane rack 201. Optionally, the bolts can be used in cooperation with nuts to achieve fastening, or the connection holes on the mounting cross beam 2011 or the buckle plate 31 can be set as threaded holes, and the bolts are used to connect with the threaded holes to achieve a firm installation.

[0044] In some embodiments, the buckle plate 31 is spaced from the outer wall surface of the water collection box 20 and forms a hook opening 311. The hook opening 311 faces the water production port 22 and is used for snapping onto the membrane rack 201. By setting the hook opening 311 to face the side of the water production port 22, that is, the hook opening 311 can face the inner side of the membrane rack 201. In this way, the buckle plate 31 can be snapped onto the mounting cross beam 2011 of the membrane rack 201 from the outside to the inside, and the operator can install the buckle plate 31 onto the membrane rack 201 from the outside of the membrane rack 201, improving the convenience of operation and the installation efficiency.

[0045] In some embodiments, the second connection portion includes a connection column 32. The connection column 32 protrudes from one end of the water collection box 20 in a direction away from the water production port 22, and the connection column 32 is used for connecting to the membrane rack 201. By using the connection column 32 and connecting the connection column 32 to the membrane rack 201, connection points between the membrane module 100 and the membrane rack 201 can be increased on the basis of the installation of the membrane module 100 using the buckle plate 31, the connection area between the membrane module 100 and the membrane rack 201 can be increased, and the supporting force of the membrane rack 201 for the installation of the membrane module 100 can be improved. Especially when multiple membrane units 10 are installed in the water collection box 20 simultaneously, the hanging weight of the water collection box 20 will increase significantly. By simultaneously providing the connection column 32 and the buckle plate 31 on the water collection box 20, the supporting strength during the installation of the water collection box 20 can be improved, and the stability of the installation of the membrane module 100 can be improved.

[0046] Optionally, the buckle plate 31 and the connection column 32 are respectively along the top direction of the water collection box 20 (such as Figure 2The z-axis direction shown) and the length direction (y-axis direction) protrude, that is, the buckle plate 31 and the extension direction of the connecting column 32 are perpendicular to each other. In this way, the buckle plate 31 and the connecting column 32 can be independently connected to the installation cross beam 2011 of the film rack 201, and the connection between the buckle plate 31 and the connecting column 32 and the film rack 201 can be non-interfering. Exemplarily, the installation cross beam 2011 of the film rack 201 is arranged as a square tube, or the installation cross beam 2011 has at least two mutually perpendicular side surfaces. In this way, the buckle plate 31 can be clamped on the top surface of the installation cross beam 2011, and the connecting column 32 can be connected to the inner side surface of the cross beam, which can ensure the independence of the installation of the buckle plate 31 and the installation of the connecting column 32. As an alternative example, the installation cross beam 2011 of the film rack 201 is provided with an installation hole for the connecting column 32 to be inserted into. The connecting column 32 is fixedly connected to the film rack 201 by being inserted into the installation hole. Optionally, the opening of the installation hole is arranged on the inner side surface of the installation cross beam 2011. When the membrane unit 10 is arranged inside the frame of the film rack 201, the connecting column 32 is inserted into the installation hole from the inner side of the installation cross beam 2011.

[0047] Since the connecting column 32 and the buckle plate 31 are arranged on the outer surface of the water collecting box 20, during the installation or disassembly of the membrane module 100, both the connecting column 32 and the buckle plate 31 need to be connected to the film rack 201. There are no other parts that can be grasped on the outer surface of the water collecting box 20 except for the connecting parts and the buckle plate 31. The surface of the water collecting box 20 itself is smooth, and it is difficult for the operator to firmly grasp the water collecting box 20, resulting in difficulty in exerting force during construction operations and certain difficulties in loading and unloading operations. At the same time, the operator will inevitably touch the filter unit 11 easily. Since the filter unit 11 is flexible, there is a risk of scratching and damage if touched. Therefore, in some embodiments, the outer surface of the water collecting box 20 further protrudes with a wing plate 23. The wing plate 23 is provided at least at one end of the water collecting box 20 where the connecting column 32 is arranged. The protruding direction of the wing plate 23 is the same as the protruding direction of the connecting column 32, and the wing plate 23 and the connecting column 32 are arranged at intervals. By using the protruding wing plate 23, when installing the membrane module 100 onto the film rack 201 or disassembling the membrane module 100 from the film rack 201, the wing plate 23 can serve as a part for the operator to grasp. By providing a grasping part for the operator, the operator can be prevented from touching the filter unit 11 during the loading and unloading of the membrane module 100, thereby avoiding scratching or damaging the filter unit 11 and improving the reliability of the loading and unloading operations.

[0048] Optionally, the wing plate 23 can also protrude from one end of the water collecting box 20 where the water production port 22 is arranged. The wing plate 23 and the water production port 22 are arranged at intervals, and the protruding direction of the wing plate 23 is opposite to the protruding direction of the connecting column 32. In this way, when the operator loads and unloads the end of the membrane module 100 where the water production port 22 is arranged, the wing plate 23 can also be used as a grasping part, thereby avoiding touching the filter unit 11.

[0049] As an alternative example, the wing plates 23 can be provided at both ends of the water collecting box 20 and symmetrically arranged at both ends of the water collecting box 20. In this way, no matter which end the water collecting box 20 is installed at, the wing plates 23 can be used as the gripping parts, so as to avoid touching the filtering unit 11.

[0050] In some embodiments, please refer to Figure 5 and Figure 6 , the water collecting box 20 is further provided with an installation opening 24 communicating with the accommodating cavity 21. The accommodating cavity 21 includes an installation area 211 and a water collecting area 212. The installation area 211 communicates with the installation opening 24, and the water collecting area 212 communicates with the water production port 22. The pouring box 12 is arranged in the installation area 211 through the installation opening 24, so that the filtering unit 11 is located outside the installation opening 24, and the pouring box 12 seals the installation opening 24. By setting the accommodating cavity 21 as the installation area 211 and the water collecting area 212, the functions of installing the pouring box 12 in the accommodating cavity 21 and collecting and discharging the filtered water in the filtering unit 11 can be satisfied simultaneously, thereby reasonably utilizing the space of the accommodating cavity 21 in the water collecting box 20 and making the structure of the water collecting box 20 more compact. By using the pouring box 12 to seal the installation opening 24, it can be avoided that the filtered water collected in the water collecting area 212 leaks through the installation opening 24, ensuring the sealing performance of the water collecting box 20. Exemplarily, the side surface or the bottom surface of the pouring box 12 can be abutted against the installation opening 24 to achieve a sealed connection with the installation opening 24.

[0051] Optionally, glue injection holes are provided at both ends of the installation area 211. After the pouring box 12 is placed in the installation area 211, glue is injected into the accommodating space through the glue injection holes. The glue flows along the inner side surface of the installation area 211 and the outer peripheral side surface of the pouring box 12 to bond and fix the outer peripheral side surface of the pouring box 12 and the inner side surface of the installation area 211, so as to realize the bonding and fixing of the pouring box 12 and the water collecting box 20 and the sealing of the installation opening 24.

[0052] In some embodiments, the water collection box 20 further includes a partition plate 25 disposed in the installation area 211 to divide the installation area 211 into at least two installation slots 2111 along the length direction of the installation area 211, and each installation slot 2111 is used for installing the casting box 12. By using the partition plate 25 to divide the installation area 211, the space of the installation area 211 can be reasonably allocated. When multiple casting boxes 12 are installed in the installation slots 2111, it can ensure that the multiple casting boxes 12 can be arranged in an orderly manner and independently in the installation area 211, avoiding interference between the casting boxes 12. It can be understood that the partition plate 25 only divides the space of the installation area 211, but does not block the space of the water collection area 212. This means that multiple installation slots 2111 are all connected to the same water collection area 212 at the same time, and the filtered water of the membrane units 10 in each installation slot 2111 can flow into the water collection area 212. Finally, all the filtered water of the membrane units 10 is collected by the collection function of the water collection area 212 and discharged through the water production port 22.

[0053] Optionally, an installation step 26 is provided between the installation area 211 and the water collection area 212 of the water collection box 20. When the casting box 12 is installed in the installation area 211, the casting box 12 abuts against the step surface of the installation step 26. Therefore, the casting box 12 cannot extend into the water collection area 212, thus leaving the space of the water collection area 212 for the filtered water to pass through.

[0054] In some embodiments, an anti - detachment groove 2112 is further provided on the inner wall surface of the installation area 211, and a plug is inserted into the anti - detachment groove 2112. When the plug is inserted into the anti - detachment groove 2112, the plug protrudes from the inner wall surface of the installation area 211. When the casting box 12 is installed in the installation area 211, the plug abuts against the outer peripheral side surface of the casting box 12. By providing the plug, the contact area between the inner wall surface of the installation area 211 and the outer peripheral side surface of the casting box 12 can be increased, and by using the mutual abutting action between the protruding plug and the casting box 12, the friction between the casting box 12 and the water collection box 20 can be increased, so that the casting box 12 is not easily detached from the water collection box 20, improving the connection strength and connection reliability between the casting box 12 and the water collection box 20.

[0055] Optionally, multiple anti - detachment grooves 2112 can be arranged at intervals along the circumferential direction of the inner wall surface of the installation area 211, and the plug can be inserted into the multiple anti - detachment grooves 2112, which can further increase the contact area between the plug and the casting box 12 and improve the installation stability of the casting box 12.

[0056] In a second aspect, please refer to Figure 7, the present application further provides a membrane module system 200, which includes a membrane rack 201 and the membrane module 100 provided in the first aspect. The membrane rack 201 includes a mounting cross beam 2011, and the water collection box 20 is installed on the mounting cross beam 2011 through a connection unit 30. Optionally, the membrane rack 201 further includes vertically arranged support columns 2012.
