Ceramic membrane technology is a key technology for upgrading and retrofitting sewage treatment plants and waterworks under the new circumstances. In the application of ceramic membranes, the form of the membrane sheet and membrane module directly affects the application effect. Ceramic flat sheet membranes operate under external pressure, requiring only membrane sheet fixing, and are installed submerged, making them widely applicable and convenient.

[0003] Existing ceramic membrane modules mostly adopt a vertical installation method, resulting in low packing density and problems such as easy clogging and cleaning dead zones during operation. In addition, traditional horizontal designs have technical defects such as insufficient membrane support strength, uneven water distribution, complex sealing structure, and high maintenance and replacement costs. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a horizontal ceramic flat-panel membrane module that improves anti-fouling properties, ease of maintenance, structural stability, and high packing density.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A horizontal ceramic flat sheet membrane module, comprising

[0007] The support foot square tube and the frame square tube form a rectangular frame structure. There are four support foot square tubes, which are located at the corners of the frame structure. The four support foot square tubes are interconnected with the interior of the frame square tube. One of the support foot square tubes serves as a water production pipeline, another of the support foot square tubes serves as an aeration pipeline, and the other two support foot square tubes are closed.

[0008] The frame structure is equipped with several aeration pipes, and the aeration pipes are internally connected to the frame square tubes connected at their ends.

[0012] Preferably, L-shaped angle steel is installed on the outside of the frame square tube corresponding to the long side of the frame structure;

[0013] The membrane panel has a Z-shaped cross-section and is connected to an L-shaped angle steel by bending the ends of the membrane panel.

[0014] Preferably, a concave angle steel is installed on the inner side of the frame square tube corresponding to the L-shaped angle steel.

[0015] Preferably, a rubber pad is provided on the outer side of the connection between the upright surface of the membrane panel and the top bent structure.

It has high integration, simple and stable structure, strong anti-fouling ability, easy maintenance, high packing density, and low water flow resistance loss. Furthermore, the outlet and aeration port are integrated with the membrane module component, making the pressure of the entire ceramic flat sheet membrane module more balanced.

[0023] In a preferred embodiment, this utility model provides a horizontal ceramic flat-plate membrane module that changes the separate connection method of the water collection pipe.

Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this technical solution clearer, the following detailed description, in conjunction with specific embodiments, further illustrates this technical solution. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this technical solution.

[0033] like Figures 1-5 As shown, this embodiment proposes a horizontal ceramic flat-plate membrane module, including support foot square tubes 2 and frame square tubes. The frame square tubes form a rectangular frame structure. There are four support foot square tubes 2, located at the corners of the frame structure. The four support foot square tubes 2 are interconnected with the interior of the frame square tubes. One of the support foot square tubes 2 serves as a product water pipeline, another as an aeration pipeline 13, and the remaining two support foot square tubes 2 are closed. In this embodiment, any two of the support foot square tubes 2 are closed, and flanges are welded to the ends of the remaining two support foot square tubes 2. The first flange structure is welded to the support foot square tube 2 and serves as the product water flange interface. The other flange interface 6 is welded to the other and serves as the aeration flange interface.

[0034] The frame square tube is divided into a first stainless steel square tube 8, which serves as the long side, and a second stainless steel square tube 9, which serves as the short side. The frame square tube is used as both a water production channel and an aeration channel.

[0035] Several aeration pipes 13 are installed in the frame structure, and the aeration pipes 13 are internally connected to the frame square tubes connected at their ends. In this embodiment, a channel is opened on the side wall opposite to the second stainless steel square tube 9, and the two ends of the aeration pipe 13 are connected to the channel. When the ends of the aeration pipe 13 are installed on the corresponding channels, the aeration pipe 13 can be internally connected to the frame structure square tubes, forming an aeration pipe 13 path. The bottom of the support foot square tube 2 is welded to the support foot flange 1. The side of the support foot square tube 2 has through holes for connecting and communicating with the first stainless steel square tube 8 and the second stainless steel square tube 9. The top of the support foot square tube 2 is welded and fixed to the first flange interface 3 and the second flange interface 6. Any two flange interfaces serve as the water outlet and the aeration port, and the other two flange interfaces are sealed with blind flanges.

[0036] A membrane module guard plate 4 with four side borders is installed on top of the frame structure. Because the membrane module guard plate 4 is airtight, it can form an air-gathering structure, confining the gas generated by aeration within the area locked by the ceramic membrane sheets 7. Several ceramic membrane sheets 7 are vertically installed inside the enclosure of the membrane module guard plate 4, and each ceramic membrane sheet 7 is equipped with a water collection port. This water collection port is connected to the product water pipeline through the frame structure. Each ceramic membrane sheet 7 is spatially perpendicular to the membrane module guard plate 4.

[0037] In the connection structure, preferably, a positioning slot 12 is provided on the top of a frame square tube on one side of the frame structure corresponding to the long side, and a pin structure is provided on one side of the ceramic diaphragm 7. The ceramic diaphragm 7 is installed in the positioning slot 12 through the pin structure. An elongated hole is provided on the top of a frame square tube on the other side of the frame structure corresponding to the long side, and the other side opposite to the pin structure is installed in the elongated hole for fixation.

[0038] An L-shaped angle steel 10 is installed on the outside of the frame square tube corresponding to the long side of the frame structure, and a concave angle steel 11 is installed on the inside of the frame square tube corresponding to the L-shaped angle steel 10. The membrane module guard plate 4 has a "Z" self-contained structure in cross-section, and the membrane module guard plate 4 is connected to the L-shaped angle steel 10 through the bent side of the end. The L-shaped angle steel 10 and the concave angle steel 11 are fixedly connected to the membrane module guard plate 4 by bolts for gas collection of the membrane module components. The first stainless steel square tube 8 has a through hole for connecting and fixing the positioning slot 12, and another first stainless steel square tube 8 has a fixed elongated hole, which is arranged opposite to the positioning slot 12 for supporting and fixing the ceramic membrane 7. The ceramic membrane 7 consists of multiple ceramic flat membranes arranged in parallel at intervals. The ceramic membrane 7 is a flat hollow structure and has a water outlet on it. The water collection system is connected to the water outlet for collecting the water filtered by the ceramic membrane 7. The working process of the ceramic membrane 7 is as follows: external sewage passes through the surface of the ceramic membrane 7 under pressure (while being filtered by it) and enters its interior, and then is discharged into the water collection system through its outlet and collected. The water collection system is integrated with the membrane module component and includes a first stainless steel square tube 8, a second stainless steel square tube 9, and a first flange interface 3.

[0039] The aeration system includes a first stainless steel square tube 8, a second stainless steel square tube 9, a support foot square tube 2 and a support foot flange 1, a second flange interface 6, and an aeration pipe 13. The second stainless steel square tube 9 has an inner channel. The aeration pipe 13 is connected and fixed to the membrane module components via fittings and connected to the second flange interface 6 to form the aeration system. Up to six aeration pipes 13 can be installed. The aeration pipes 13 can be perforated aeration pipes 13 or titanium rod aeration pipes 13, which can be used for air aeration or aeration of special gases such as pure oxygen and ozone. This allows the horizontal ceramic flat-plate membrane module of this invention to be combined with different processes and applied to different scenarios (such as biological wastewater treatment, advanced wastewater treatment, and drinking water treatment).

[0040] The membrane module components can be arranged in multiple layers, allowing rising water and airflow to freely enter the parallel ceramic membrane sheets 7, improving the pumping and water production efficiency. When multiple flat-plate ceramic membrane modules are arranged in a series, the water flow can reach the next flat-plate ceramic membrane module sequentially, resulting in low water flow resistance loss. In addition, the membrane module guard plate 4 can also protect the ceramic membrane sheets 77 from impact damage and increase the overall rigidity of the equipment. Furthermore, a rubber pad 5 is provided on the outer side of the connection between the vertical surface of the membrane module guard plate 4 and the top bent structure, serving as a liner when multiple flat-plate ceramic membrane modules are arranged in a series.

[0041] A horizontal ceramic flat sheet membrane module uses 304 stainless steel as its material, making it suitable for most application environments.

[0042] The ceramic membrane 7 uses alumina as the main material, supplemented with materials such as silicon oxide to improve the surface properties of the ceramic membrane. The micropore size inside the ceramic membrane 7 substrate is 1~8μm, the micropore size of the transition layer is 0.5~2μm, and the micropore size of the surface film layer is 0.05~0.1μm.

[0043] like Figure 6 As shown, the membrane module assembly can be loaded with 75 ceramic diaphragm sheets 7. The length of the membrane module assembly can be changed according to the number of diaphragm sheets used. The membrane module assembly can be used in multiple layers, loading multiple ceramic diaphragm sheets 7 for large-scale use. The length and width specifications of the ceramic diaphragm sheet 7 include, but are not limited to, 1 meter in length and 0.25 meters in width.

[0044] The above content is only a preferred embodiment of this utility model. For those skilled in the art, many changes can be made in the specific implementation and application scope based on the ideas of this technical content. As long as these changes do not depart from the concept of this utility model, they all fall within the protection scope of this patent.
