Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane modules, and particularly relates to a novel installation frame for MBR membrane modules. Background Art

[0002] In the current market, the commonly used layout method of the immersed MBR (MBR, also known as membrane bioreactor, with the full English name of Membrane Bio-Reactor) pool is that the membrane module and most of the water production pipes are immersed below the liquid level, and the aeration system is installed at the bottom of the pool. There are many disadvantages in actual operation:

[0003] 1. When performing off-line cleaning or maintenance, it is necessary to stop the machine and lower the water level to a relatively low level before the relevant pipelines can be disassembled and the membrane module can be taken out.

[0004] 2. When the aerator is damaged or blocked, it is necessary to first take out the membrane module and then completely drain the water and clean the pool before any operation can be carried out. The measures for maintenance and replacement are very costly, and the operation is also very dangerous under limited space conditions.

[0005] 3. After long-term operation, it can be found during cleaning that the activated sludge accumulated at the lower end of the membrane sheet is significantly more than that at the upper end. This is because the bubbles generated by ordinary aerators are relatively fine at the beginning, which is conducive to oxygen mass transfer but not conducive to water flow disturbance. Therefore, the scouring effect on the membrane filaments at the lower end of the membrane sheet is relatively weak; the bubbles continuously combine during the rising process and become larger and larger, and the scouring and impact effect on the membrane filaments also becomes stronger and stronger. After long-term accumulation, it causes an imbalance in the flux between the upper and lower parts of the membrane filaments.

[0006] 4. Long-term operation in a poor environment leads to frequent backwashing of the membrane system, increased system energy consumption, and thus inconvenient use. Content of the Utility Model

[0007] In order to overcome the deficiency that when the aerator is damaged or blocked in the prior art, it is necessary to first take out the membrane module and then completely drain the water and clean the pool before any operation can be carried out, and the measures for maintenance and replacement are relatively costly, one of the purposes of the utility model is to provide a novel installation frame for MBR membrane modules.

[0008] One of the purposes of the utility model is achieved by the following technical solution: a novel MBR membrane assembly installation frame, including a membrane support mechanism: the membrane support mechanism includes a first support vertical plate, one side of the first support vertical plate is symmetrically fixedly connected to a first horizontal plate, the other side of the first horizontal plate is fixedly connected to a second support vertical plate, one side of the second support vertical plate is symmetrically fixedly connected to a second horizontal plate, the other side of the second horizontal plate is fixedly connected to a third support vertical plate, one side of the third support vertical plate is symmetrically fixedly connected to a third horizontal plate, the other side of the third horizontal plate is fixedly connected to a fourth support vertical plate, one side of the fourth support vertical plate is symmetrically fixedly connected to a fourth horizontal plate, the other side of the fourth horizontal plate is fixedly connected to the first support vertical plate The first transverse plate is fixedly connected to the middle of the first transverse plate, the other end of the water main pipe is fixedly connected to the side wall of the third transverse plate, the side wall of the third transverse plate is fixedly connected to the aeration main pipe, the aeration main pipe is fixedly connected to the water main pipe, the first MBR diaphragm is equidistantly installed between the fourth transverse plate and the aeration main pipe, the second MBR diaphragm is equidistantly installed between the second transverse plate and the aeration main pipe, the first interface flange is fixedly connected to the upper surface of one side of the water main pipe, the second interface flange is fixedly connected to the upper surface of one side of the aeration main pipe, the third interface flange is fixedly connected to the middle of the lower surface of the water main pipe, and a swirl aeration head is installed in the middle of the lower surface of the water main pipe. It is convenient to assemble the components together, thereby improving the integration of the device and facilitating maintenance performance.

[0009] According to the novel MBR membrane assembly installation frame, the side wall of the fourth horizontal plate close to the first MBR membrane is equidistantly provided with plug holes, the side of the aeration main pipe close to the first MBR membrane is equidistantly fixedly connected with installation joints, the side of the first MBR membrane close to the plug holes is equidistantly fixedly connected with plug rods, and the side of the first MBR membrane close to the installation joint is equidistantly fixedly connected with plug joints, so as to facilitate installation and removal of the first MBR membrane.

[0010] According to the novel MBR membrane assembly installation frame, the working principle, structure and installation method of the second MBR membrane are consistent with those of the first MBR membrane, which facilitates installation and removal of the second MBR membrane.

[0011] According to the novel MBR membrane assembly installation frame, the outer surface of the cyclone aeration head is fixedly connected with a fourth interface flange, the third interface flange and the fourth interface flange are connected by bolts, and the water production main pipe is installed with the cyclone aeration head through the third interface flange and the fourth interface flange, so as to facilitate the assembly of the components together.

[0012] According to the described new MBR membrane module installation framework, lifting lugs are fixedly connected to one side of the first support vertical plate, the second support vertical plate, the third support vertical plate, and the fourth support vertical plate. This facilitates the hoisting and placement of the device as well as hoisting for maintenance.

[0013] According to the described new MBR membrane module installation framework, the number of lifting lugs is four, and the sizes and shapes of the four lifting lugs are all the same. This facilitates hoisting.

[0014] According to the described new MBR membrane module installation framework, the overall membrane support mechanism is welded from stainless steel square tubes. This improves the overall stability of the membrane support mechanism.

[0015] According to the described new MBR membrane module installation framework, both the water production main pipe and the aeration main pipe are made of stainless steel square tubes.

[0018] 2. Through the setting of the swirl aeration head, by optimizing the aeration method, while increasing the oxygen transfer rate, the scouring effect on the surfaces of the first MBR membrane sheet and the second MBR membrane sheet is increased, which can maintain a relatively low transmembrane pressure difference for a long time, effectively reducing the number of backwashes and the labor costs, chemical agent costs, and energy consumption generated thereby, and further effectively reducing the replacement frequency of the first MBR membrane sheet and the second MBR membrane sheet.

On the other side of the second horizontal plates 104, a third support vertical plate 105 is fixedly connected. On one side of the third support vertical plate 105, third horizontal plates 106 are symmetrically and fixedly connected. On the other side of the third horizontal plates 106, a fourth support vertical plate 107 is fixedly connected. On one side of the fourth support vertical plate 107, fourth horizontal plates 108 are symmetrically and fixedly connected. On the other side of the fourth horizontal plates 108, it is fixedly connected to one side of the first support vertical plate 101. In the middle of the first horizontal plates 102, a water production main pipe 2 is fixedly connected. The other end of the water production main pipe 2 is fixedly connected to one side wall of the third horizontal plates 106. On one side wall of the third horizontal plates 106, an aeration main pipe 3 is fixedly connected. The aeration main pipe 3 is fixedly connected to the water production main pipe 2. Between the fourth horizontal plates 108 and the aeration main pipe 3, first MBR membrane sheets 4 are installed at equal intervals. Between the second horizontal plates 104 and the aeration main pipe 3, second MBR membrane sheets 5 are installed at equal intervals. On the upper surface of one side of the water production main pipe 2, a first interface flange 6 is fixedly connected. On the upper surface of one side of the aeration main pipe 3, a second interface flange 7 is fixedly connected. In the middle of the lower surface of the water production main pipe 2, a third interface flange 8 is fixedly connected. In the middle of the lower surface of the water production main pipe 2, a swirl aeration head 9 is installed. On the side wall of the fourth horizontal plates 108 close to the first MBR membrane sheets 4, insertion holes 10 are opened at equal intervals. On the side of the aeration main pipe 3 close to the first MBR membrane sheets 4, installation joints 11 are fixedly connected at equal intervals. On the side of the first MBR membrane sheets 4 close to the insertion holes 10, insertion rods 12 are fixedly connected at equal intervals. On the side of the first MBR membrane sheets 4 close to the installation joints 11, plug-in joints 13 are fixedly connected at equal intervals. The working principle, structure, and installation method of the second MBR membrane sheets 5 are the same as those of the first MBR membrane sheets 4. On the outer surface of the swirl aeration head 9, a fourth interface flange 14 is fixedly connected. The third interface flange 8 and the fourth interface flange 14 are connected by bolts. The water production main pipe 2 is installed with the swirl aeration head 9 through the third interface flange 8 and the fourth interface flange 14. On one side of the first support vertical plate 101, the second support vertical plate 103, the third support vertical plate 105, and the fourth support vertical plate 107, lifting ears 15 are fixedly connected. The number of lifting ears 15 is four. The sizes and shapes of the four lifting ears 15 are all the same. The overall membrane support mechanism 1 is welded by stainless steel square tubes. The water production main pipe 2 and the aeration main pipe 3 are both made of stainless steel square tubes.During installation, the first MBR membrane sheet 4 (MBR, also known as Membrane Bio-Reactor) and the second MBR membrane sheet 5 are installed on the membrane support mechanism 1 through the installation joint 11, the plug joint 13, the socket 10 and the plug rod 12.

After the installation is completed, after checking the airtightness, the device is hoisted into the MBR membrane tank (MBR, also known as Membrane Bio-Reactor) or the integrated equipment space at one time. During normal operation, due to the advantages of the swirl aeration head 9 such as a large upward air vortex and strong stirring force, the mixture of air, activated sludge and sewage generates a violent vortex flow through the swirl cutter during the high-speed upward process, realizing efficient mixing and at the same time forming a circulating flow, thereby flushing the first MBR membrane sheet 4 and the second MBR membrane sheet 5. When maintenance and replacement are required, there is no need to completely drain the water. It is only necessary to lower the water level below the levels of the second interface flange 7 and the first interface flange 6 to release the bad gas in the pool body. Then, the device is stably lifted to an open area through the lifting ear 15, so that the first MBR membrane sheet 4 and the second MBR membrane sheet 5 can be disassembled, washed or replaced through the plug rod 12, the socket 10, the plug joint 13 and the installation joint 11. And the third interface flange 8 and the fourth interface flange 14 are disassembled and separated by bolts, so that the swirl aeration head 9 can be disassembled, washed or replaced. The maintenance and cleaning are relatively convenient, and the installation is simple and convenient. At the same time, there is no need to empty the pool or even stop production, and the installation or maintenance can be carried out online with water, thus avoiding the limited-space operation of disassembly, installation and maintenance and the related occupational risks caused thereby.

[0031] Working principle: During installation, the first MBR membrane sheet 4 (MBR, also known as Membrane Bio-Reactor) and the second MBR membrane sheet 5 are installed on the membrane support mechanism 1 through the installation joint 11, the plug joint 13, the socket 10 and the plug rod 12. Then, the main aeration pipe 3 is connected to the outlet pipeline of the blower equipped in the system through the second interface flange 7, and at the same time, the main water production pipe 2 is connected to the outlet pipeline of the water production pump equipped in the system through the first interface flange 6. After the installation is completed and the air tightness is inspected, the device is hoisted into the MBR membrane tank (MBR, also known as Membrane Bio-Reactor) or the integrated equipment space at one time. During normal operation, due to the advantages of the swirling aeration head 9 such as a large upward air vortex and strong stirring force, the mixture of air, activated sludge and sewage generates a violent swirling flow through the swirl cutter during the high-speed upward process, realizing efficient mixing and at the same time forming a circulating flow, thereby flushing the first MBR membrane sheet 4 and the second MBR membrane sheet 5. When maintenance and replacement are required, it is not necessary to completely drain the water. It is only necessary to lower the water level below the levels of the second interface flange 7 and the first interface flange 6 to release the bad gas in the pool body. Then, the device is stably hoisted to an open area through the lifting ear 15, so that the first MBR membrane sheet 4 and the second MBR membrane sheet 5 can be disassembled, washed or replaced through the plug rod 12, the socket 10, the plug joint 13 and the installation joint 11. And the third interface flange 8 and the fourth interface flange 14 are disassembled and separated by bolts, so that the swirling aeration head 9 can be disassembled, washed or replaced. The maintenance and cleaning are relatively convenient, and the installation is simple and convenient. At the same time, it is not necessary to empty the pool or even stop production, and it can be installed or maintained online with water, thus avoiding the limited-space operation of disassembly, installation and maintenance and the related occupational risks caused thereby.
