Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of sewage purification equipment, and specifically relates to an aeration pipe dredging device. Background Art
[0002] The sewage purification treatment of the cigarette factory is mainly completed by the membrane pool aeration system of the reclaimed water treatment station. The membrane pool is equipped with an MBR membrane. The sewage enters the inside of the MBR membrane through the MBR membrane, thereby filtering the sewage. Dissolved oxygen is injected into the water body through the aeration pipe to promote the biochemical reaction between the organic matter in the sewage and oxygen to degrade the organic matter. By increasing the contact area between the gas and the water body and improving the solubility of oxygen, on the one hand, it can accelerate the effect of aeration treatment, and on the other hand, it can also flush the surface of the membrane to prevent the membrane surface from being blocked. The aeration pipe at the bottom of the membrane assembly in the membrane pool of the reclaimed water treatment station is equipped with an aerator, and a set of aerators are installed on each side. The aerator blows compressed air to the bottom of the aeration tank in an oblique downward direction, and then the gas rises and contacts the entire aeration tank water body, so that the reaction efficiency between organic matter and oxygen is maximized. At the same time, the aerator installed on the aeration pipe at the bottom of the membrane assembly is inclined downward at 45° to the horizontal plane to prevent the falling activated sludge from entering the aerator when the aeration fan stops running.
[0003] However, during long-term operation, it is inevitable that some active sludge will enter the aeration pipe through the holes of the aerator, causing the aeration pipe to be blocked and the compressed air injected into the aeration tank to be reduced, thereby reducing the aeration effect.

[0027] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below in conjunction with the accompanying drawings to facilitate understanding by technical personnel.
[0028] Embodiment 1:
[0029] See also Figure 1 and Figure 2 , an aeration pipe dredging device, comprising an aeration pipe 1, an MBR membrane assembly 3 and an exhaust pipe 4, the aeration pipe 1 comprising a main aeration pipe 10 and an aeration branch pipe 20, both of which are provided with a gate valve 11, an aeration device is provided at the lower end of the aeration branch pipe 20, a three-way joint at the upper end of the aeration branch pipe 20 is connected with the main aeration pipe 10, and the lower end of the aeration branch pipe 20 extends below the MBR membrane assembly 3, and the aeration pipe dredging device also includes a backwashing pipe 5;
[0030] The lower end of the exhaust pipe 4 is connected to the aeration branch pipe 20, and the upper part of the exhaust pipe 4 is connected to the backwash pipe 5;
[0031] An exhaust valve 41 is provided at the top of the exhaust pipe 4, and a ball valve 51 is provided in the middle of the backwash pipe 5;
[0032] The backwash pipe 5 is used to reversely guide the compressed air in the unblocked aeration branch pipe 20 into the blocked aeration branch pipe 20 to disperse the sludge in the blocked aeration branch pipe 20 .
[0033] The aeration branch pipe 20 and the MBR membrane assembly 3 are located in the aeration tank. The main aeration pipe 10 delivers compressed air into the aeration branch pipe 20, and then the compressed air is injected into the bottom of the aeration tank through the aerator at the end of the aeration branch pipe 20. After the gas rises, it contacts the water in the entire aeration tank, so that the organic matter and oxygen undergo a biochemical reaction, thereby degrading the organic matter; the sewage enters the inside of the MBR membrane from the outside of the MBR membrane, thereby filtering the sewage; the gate valve 11 on the main aeration pipe 10 is used to open or close the compressed air in The passage in the main aeration pipe 10; the gate valve 11 on the aeration branch pipe 20 is used to open or close the passage of compressed air in the aeration branch pipe 20; the exhaust gas in the main aeration pipe 10 and the aeration branch pipe 20 is discharged through the exhaust pipe 4; the exhaust valve 41 is used to open or close the passage of the exhaust gas in the exhaust pipe 4, and at the same time, the exhaust valve 41 can also be used to detect whether the aeration branch pipe 20 is blocked. If the exhaust valve 41 is not exhausted smoothly, it means that the aeration branch pipe 20 is blocked. If the exhaust valve 41 is exhausted smoothly, it means that the aeration branch pipe 20 is operating well.
[0034] Six groups of MBR membrane modules 3, aeration branches 20, exhaust pipes 4 and exhaust valves 41 are provided respectively.
[0035] like Figure 2 As shown, taking the first group of aeration branch pipes 20 and the second group of aeration branch pipes 20 as an example, the left side is the first group of aeration branch pipes 20, and the right side is the second group of aeration branch pipes 20;
[0036] The unblocking principle of the aeration pipe 1 is as follows: initially, the ball valve 51 is closed and all the exhaust valves 41 are opened. When it is detected that the first group of aeration branch pipes 20 are blocked, all the exhaust valves 41 are closed, and the compressed air enters the second group of aeration branch pipes 20 and the second group of exhaust pipes 4 from the main aeration pipe 10, and then enters the backwash pipe 5 after passing through the second group of exhaust pipes 4. The ball valve 51 is opened, and the compressed air enters the first group of exhaust pipes 4 through the backwash pipe 5, and then enters the first group of aeration branch pipes 20, and impacts the silt blocked in the first group of aeration branch pipes 20, breaks up the silt blocked in the inner wall of the pipe, and finally opens the first group of exhaust valves 41 until the first group of exhaust valves 41 can be exhausted smoothly, that is, the unblocking is completed. Through the above process, the problem of reduced aeration effect of the aeration pipe 1 due to pipeline blockage is avoided.
[0037] Embodiment 2:
[0038] See also Figure 1 and Figure 2 The two exhaust pipes 4 at the beginning and the end are connected to the exhaust valve 41 and the backwash pipe 5 through three-way joints, and the four exhaust pipes 4 in the middle are connected to the exhaust valve 41 and the backwash pipe 5 through four-way joints.
[0039] The six groups of exhaust pipes 4 , backwash pipes 5 and exhaust valves 41 are connected through three-way joints and four-way joints, so that the compressed air in the exhaust pipes 4 can enter the backwash pipes 5 , and the compressed air in the backwash pipes 5 can also enter the exhaust pipes 4 .
[0040] A group of ball valves 51 is provided on the backwash pipes 5 between two adjacent exhaust pipes 4, and five groups are provided in total.
[0041] Since six groups of exhaust pipes 4 are provided, the backwash pipe 5 is divided into five parts by two adjacent exhaust pipes 4. A ball valve 51 is provided in each part to control the flow of compressed air in the backwash pipe 5 of that part. As long as it is detected that one group of aeration branch pipes 20 is blocked, the ball valve 51 closest to the group of aeration branch pipes 20 is opened, so that the compressed air in the adjacent aeration branch pipes 20 can be introduced into the blocked aeration branch pipes 20 to achieve backwashing of the sludge.
[0042] The main aeration pipe 1 is connected to the aeration fan.
[0043] The aeration fan is used to generate compressed air and introduce the compressed air into the main aeration pipe 1.
[0044] The aeration pipe dredging device also includes an auxiliary aeration pipe 6 connected to the main aeration pipe 1 .
[0045] The auxiliary aeration pipe is set at the bottom of the aeration tank to inject more air into the aeration tank to enhance the aeration effect and improve the water purification efficiency.
[0046] A flow meter 12 is also provided on the main aeration pipe 1 , and the flow meter 12 is fixed above the gate valve 11 .
[0047] The flow meter 12 is used to measure the flow rate of the compressed air in the main aeration pipe 1 to detect whether the air flow rate in the pipe is within the target range.
[0048] The working process of the present application is as follows: start the aeration fan, close the exhaust valve 41 and the ball valve 51, and the compressed air enters each group of MBR membrane components 3 and the aeration branch pipe 20 through the main aeration pipe 1. If an aeration branch pipe 20 is blocked, open the adjacent ball valve 51, so that the compressed air inside the adjacent aeration branch pipe 20 enters the blocked aeration branch pipe 20 through the exhaust pipe 4 and the backwash pipe 5 in turn, and open the exhaust valve 41 of the blocked pipe until the exhaust valve 41 can be discharged smoothly to complete the unblocking.
[0049] In summary, the present application sets a backwash pipe 5 and a ball valve 51 to reversely guide the compressed air in the unblocked aeration branch pipe 20 into the blocked aeration branch pipe 20 to disperse the sludge inside the blocked aeration branch pipe 20, so that the aeration branch pipe 20 of the aeration pipe 1 does not need to be shut down after being blocked, and does not need to be manually unblocked by wire rope. It only needs to open the ball valve 51 of the adjacent pipeline after the pipeline is blocked to flush the sludge in the blocked pipeline, thereby unblocking the pipeline and avoiding the problem of reduced aeration effect of the aeration pipe 1 due to pipeline blockage. The present application has the advantages of easy operation, short flushing time, low energy consumption, and convenient maintenance and cleaning.
[0050] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of the present application rather than to limit it.
