Description

Technical Field

[0001] This utility model relates to the technical field of MBR membrane reactor devices, and in particular to an MBR membrane reactor device. Background Technology

[0002] MBR stands for Membrane Bio-Reactor, a novel wastewater treatment system that organically combines membrane separation technology with biological treatment technology.

[0003] MBR membranes combine membrane separation technology with biological treatment technology to replace the secondary sedimentation tank in traditional wastewater treatment. They use membrane modules to trap activated sludge and macromolecular organic matter, thereby improving treatment efficiency. However, they still have the following drawbacks: the disassembly process of MBR membranes is relatively troublesome. When MBR membranes are damaged and need to be repaired or replaced, a lot of time and effort are required. Not only is the labor intensity high, but the long replacement time can also easily damage the MBR membrane. Utility Model Content

[0022] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.

[0023] Reference Figures 1-3 An MBR membrane reactor includes a housing 5, with a locking block 7 adhered to the inner wall of one side of the housing 5. A slot is provided on one side of the locking block 7, and a baffle 6 is inserted into the slot on one side. The locking block 7 is made of rubber, and the size of the slot is slightly smaller than the thickness of the baffle 6. Through the compression of the baffle 6 and the elasticity of the rubber, the baffle 6 will be firmly locked in the slot, which enhances the stability of the baffle 6.

[0024] A slot 11 is provided on the inner wall of one side of the housing 5 at the top position. A baffle 6 is slidably connected in the slot 11. The bottom of the baffle 6 contacts the top of multiple limiting blocks 18. When the limiting blocks 18 are in a stable state, the baffle 6 is pushed, and the baffle 6 compresses the limiting blocks 18. The baffle 6 gives the limiting blocks 18 a downward pressure, which makes the limiting blocks 18 fit more tightly in the limiting groove 17, thus enhancing stability.

[0025] Multiple limiting plates 16 are fixed to the inner wall of the housing 5 at the top position by bolts. A limiting groove 17 is provided between each pair of adjacent limiting plates 16. A limiting block 18 is slidably connected in the limiting groove 17. An installation groove is opened at the bottom of the limiting block 18.

[0026] Multiple fixing plates 19 are bolted to the bottom of the inner wall of the housing 5. The fixing plates 19 are metal plates. Two insertion holes 12 are opened on the top of the fixing plates 19. The multiple fixing plates 19 are aligned with the center of the limiting groove 17. An MBR membrane module 2 is provided between the fixing plates 19 and the limiting block 18. The MBR membrane module 2 includes an MBR membrane, a product water pipe 10 and a fixing pipe 8. The product water pipe 10 and the fixing pipe 8 are located at the two ends of the MBR membrane. A magnetic block 9 is provided below the fixing pipe 8. The two magnetic blocks 9 are inserted into the insertion holes 12. A product water channel is opened on one side of the inner wall of the housing 5. The multiple product water pipes 10 are all connected to the product water channel.

[0027] During installation, the MBR membrane module is first installed between the fixed plate 19 and the limiting block 18. Specifically, the permeate pipe 10 is inserted into the mounting groove at the bottom of the limiting block 18, and the magnetic blocks 9 on both sides of the fixed pipe 8 are inserted into the insertion hole 12. The magnetic blocks 9 magnetically attract the insertion hole 12, thus making the magnetic blocks 9 adsorbed in the insertion hole 12, which improves the convenience of installation.

[0028] When disassembly is required, first drain the water inside the reactor housing 5, then separate the magnetic block 9 from the socket 12, pull the limiting block 18 and the fixing tube 8 to disengage them from the socket 12, take out the generating tube 10, and complete the disassembly of the MBR membrane module, which improves the speed and safety of disassembly.

[0029] The difference between a multi-unit design and a single MBR membrane module is that when one of them fails, the damaged MBR membrane module can be removed and replaced for repair, increasing the applicability of the MBR membrane module.

[0030] In this utility model, a fixing block 15 is fixed to one side of the housing 5 by bolts. An air inlet pipe 3 is fixed inside the fixing block 15 by bolts. A flange 4 is fixed to the top of the air inlet pipe 3 by bolts. The flange connection achieves a good sealing effect through a sealing gasket or sealing surface, which can effectively prevent fluid or gas from leaking at the connection and ensure the safe and stable operation of the air inlet pipe 3. The air inlet pipe 3 is connected to an external fan, and the external fan draws air and delivers the air into the air inlet pipe 3.

[0031] In this invention, the bottom of the housing 5 is fixed with multiple mounting plates 13 by bolts, and the top of the mounting plates 13 is fixed with an aeration pipe 14 by bolts. The aeration pipe 14 has multiple one-way aeration holes. The aeration pipe 14 is sealed to the air inlet pipe 3. The air delivered to the aeration pipe 14 through the air inlet pipe 3 forms bubbles through the aeration holes. These bubbles wash the surface of the MBR membrane module during their rise, preventing pollutants from depositing on the surface of the MBR membrane module, thereby slowing down the fouling of the MBR membrane module. The mounting plates 13 provide stable support for the aeration pipe 14.

[0032] In this invention, the outer walls on both sides of the housing 5 are fixed with water inlet pipes 1 by bolts. The water inlet pipes 1 are responsible for transporting water to the MBR membrane module for effective treatment.

[0033] Working principle: First, after the MBR membrane module 2 is installed, the magnetic blocks 9 on both sides of the fixing tube 8 are inserted into the insertion hole 12. The magnetic blocks 9 magnetically attract the insertion hole 12. The permeate pipe 10 is then inserted into the mounting groove of the limiting block 18, so that the permeate pipe 10 is connected to the permeate channel.

[0034] Wastewater is pumped into the device through inlet pipe 1 using a water pump. MBR membrane module 2 then begins producing water. The produced water flows from product water pipe 10 into the product water channel and is then pumped away by external clean water extraction equipment. During water production, air bubbles are discharged from the aeration holes of aeration pipe 14. These bubbles, as they rise, wash the surface of the MBR membrane module, preventing contaminants from depositing on the surface and thus mitigating MBR membrane fouling.

[0035] When disassembly is required, first drain the wastewater inside the device, then separate the magnetic block 9 from the socket 12, open the side cover of the housing 5, and remove the product water pipe 10 from the mounting groove of the limit block 18 to complete the disassembly of the MBR membrane module. The difference between the multi-module design and the single MBR membrane module is that when one of them is damaged, the damaged MBR membrane module can be removed and replaced for repair.

Many more modifications can be made based on the teachings of this utility model, and all such modifications fall within the scope of protection claimed by this utility model.
