Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane components, in particular to an MBR curtain-type membrane component which is easy to inspect. Background Art

[0002] MBR curtain membrane module is a membrane module based on enhanced PVDF hollow fiber membrane and uniform PVDF hollow fiber membrane as the core filter material. It is widely used in membrane bioreactor technology, using membrane separation technology and biological treatment technology to replace the secondary sedimentation tank in the activated sludge method for solid-liquid separation. It is mainly composed of MBR membrane, membrane connector, membrane slot, membrane frame, water collection pipe, internal aeration main pipe and external aeration pipe. It has excellent anti-oxidation and anti-pollution properties and is usually used in the fields of sewage treatment, drinking water and seawater desalination.

[0003] The working principle of the MBR curtain membrane structure is very simple and effective. First, the water to be treated is introduced into the reaction tank through the water inlet pipe. Then, a series of membrane modules are set up in the reaction tank, and many microporous membranes are filled in the membrane modules. When water passes through the MBR curtain membrane assembly, suspended solids, colloids and microorganisms are retained by the membrane, while water molecules can be further processed through the membrane pores. In this way, the MBR curtain membrane structure can achieve the effects of solid-liquid separation and pollutant filtration at the same time.

[0004] In order to increase the water production efficiency, a plurality of MBR membranes are generally arranged on the membrane frame. Each MBR membrane is installed with a number of membrane filaments for filtration. The membrane filaments are thin and easy to break. The membrane filaments in the entire membrane frame are complicated. The current inspection method is mainly manual visual inspection one by one, which is prone to missed inspections and wrong inspections, and the inspection time is too long. If the membrane filaments are broken, it is difficult to detect it, which may easily cause the raw water to enter the produced pure water and cause pollution, affecting the quality of pure water.

[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The utility model provides an MBR curtain-type membrane component which is easy to inspect.

[0024] In the embodiment of the utility model, a MBR curtain membrane assembly that is easy to inspect, such as Figures 1 to 4 As shown, it includes a membrane frame 1 and a plurality of MBR curtain membranes 2 installed in the membrane frame 1. The MBR curtain membrane 2 includes a substrate 22 and membrane filaments 21. A water collecting chamber 222 and a plurality of observation chambers 221 arranged side by side and connected to the water collecting chamber 222 are arranged inside the substrate 22. The observation chambers 221 are transparent and visible and can be made of transparent glass or transparent resin material. A water outlet 224 connected to the water collecting chamber 222 is arranged at one end of the substrate 22. A mounting groove 223 for mounting the membrane filaments 21 is also provided at the bottom of the substrate 22. The membrane filaments 21 are mounted in the mounting groove 223. The bottom of the mounting groove 223 is connected to each observation chamber 221. The water production effect can be observed in different regions through the observation chambers 221. If the water produced in the observation chamber 221 in the corresponding region is turbid, the membrane filaments 21 can be broken and locked in the region, so that the MBR curtain membrane 2 can be quickly inspected, saving inspection time and ensuring the quality of water production.

[0025] Preferably, in order to further accurately lock a primary area, a baffle is provided in the installation groove 223 to evenly divide the installation groove 223 into a plurality of installation chambers, the installation groove 223 is divided into multiple parts, and each installation chamber is respectively connected to the observation chamber 221, thereby preventing the water production of membrane filaments 21 in different areas from interfering with each other.

[0026] Optionally, a water collecting pipe 3 is provided on one side of the membrane frame 1, and a plurality of conduits 32 are provided on one side of the water collecting pipe 3. The water outlets 224 on each substrate 22 are respectively connected to the conduits 32 to facilitate the collection of produced water.

[0027] Among them, Figure 4 As shown, the inspection of the breakage of the membrane filament 21 can also be carried out by air pressure, so valve switches 31 are provided at both ends of the water collecting pipe 3. When preparing for air pressure detection, all valve switches 31 are closed, and then the external pressure tester is connected to one of the valve switches 31 for pressure testing. Under the same output power, if the pressure value is less than the pressure value before the breakage, it can be judged that the MBR curtain membrane assembly has a leak, or air pressure can be directly applied to one of the valve switches 31 to observe the water outlet conditions at various locations. If a leak is found, it can be judged that there is a problem at the leaking location. The above method can be used to conduct a preliminary inspection of the MBR curtain membrane assembly, and then it can be further inspected in conjunction with the observation chamber 221 on the MBR curtain membrane sheet 2.

[0028] Preferably, a pressure test port is provided on one side of the water collecting pipe 3, and a pressure tester is connected to the pressure test port. When the MBR curtain membrane assembly needs to be inspected, all valve switches 31 are closed, and then a pressurization test is performed.

[0029] Optionally, a through hole communicating with the outside of the substrate 22 is provided on one side of the observation chamber 221, and a light-transmitting sheet is installed in the through hole. The light-transmitting sheet may be a light-transmitting plastic sheet or a resin material.

[0030] Alternatively, if Figures 2 to 3 As shown, a fixing block 11 is provided at the top and the bottom of the membrane frame, and a plurality of side-by-side slots 111 are provided on the fixing block 11. The slots 111 may be grooves. A snap-fitting piece 225 is provided at the top of the base 22. The snap-fitting piece 225 may be a raised guide rail. When the MBR curtain membrane 2 is installed on the membrane frame 1, the snap-fitting piece 225 is embedded in the slot 111.
