Description

Technical Field

[0001] The utility model relates to the field of wastewater treatment, in particular to an anaerobic reactor water distributor which is easy to maintain and clean. Background Art

[0002] In the field of high-concentration wastewater treatment, anaerobic reactors are increasingly used. For various types of wastewater, such as urban sewage, industrial wastewater, etc., the organic matter in these wastewaters can be effectively removed through the treatment of anaerobic reactors, and the water quality is significantly improved. The main function of the anaerobic reactor is to use anaerobic microorganisms to degrade organic matter, thereby removing organic pollutants in the wastewater. Specifically, the water distribution system of the anaerobic reactor evenly distributes the sewage to the bottom of the anaerobic reactor, and then passes through the packing layer and anaerobic sludge bed in the reactor. Under the action of anaerobic microorganisms, the organic matter is decomposed into small molecular organic matter and gas (such as methane, etc.). These small molecular organic matter can be adsorbed and grown by microorganisms, further degrading the organic pollutants in the wastewater. Combined with other treatment technologies, it can effectively and thoroughly remove organic matter and other pollutants in the wastewater and reduce the impact on the environment.

[0003] The anaerobic water distributor is one of the important components of the anaerobic reactor. The water distribution system in the anaerobic reactor is responsible for evenly distributing the sewage to the bottom of the reactor to ensure that the sewage can fully contact with the anaerobic microorganisms and improve the removal efficiency of organic matter. In certain types of anaerobic reactors such as upflow anaerobic sludge blanket reactors, the water distribution system is particularly important. It returns the sewage to the bottom of the reactor through pumps and pipes, and allows the sewage to continuously pass through the sludge layer in the reactor in an internal circulation manner. This water distribution method can make the sewage fully contact with the sludge and improve the removal efficiency of organic matter.

[0004] The design of the water distribution system will affect the treatment effect of the anaerobic reactor. If the water distribution is uneven, the sludge concentration in some areas will be too high, while other areas may lack sufficient sludge. This will lead to a decrease in the efficiency of organic matter removal and may even cause problems such as sludge bulking. In addition, due to the high indicators such as SS and hardness of the treated sewage, the blockage of the water distributor is also a common problem. The water distributor needs to be cleaned immediately after being blocked, otherwise it will aggravate the blockage site and eventually cause the water distributor to lose its water distribution ability and have to be replaced. However, the cleaning and maintenance of the water distributors of many anaerobic reactors are difficult. They need to be disassembled for cleaning and maintenance when the anaerobic reactor is shut down for overhaul. They do not have the ability to disassemble and clean online. In view of this, we propose an anaerobic reactor water distributor that is easy to maintain and clean to solve the existing problems. Utility Model Content

[0005] The utility model aims to provide an anaerobic reactor water distributor which is easy to maintain and clean, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anaerobic reactor water distributor that is easy to maintain and clean, comprising an annular water distribution pipe, a water distribution pipe, a control valve, a pressure detection component, a water distribution pipe connecting component and an anaerobic reaction tank, wherein a plurality of sets of sleeves are embedded on the upper side of the anaerobic reaction tank, and a water distribution pipe connecting component is provided on the sleeve, the sleeve is movably connected to the water distribution pipe through the water distribution pipe connecting component, and the side of the water distribution pipe away from the sleeve is fixedly connected to the annular water distribution pipe.

[0007] Preferably, the water distribution pipe connection assembly includes fixing bolts, fixing flanges, pipe connecting flanges, sealing gaskets and stainless steel balls. The sleeve is provided with a pipe connecting flange, the sleeve is movably connected to the water distribution pipe through the pipe connecting flange, and sealing gaskets are provided on the water distribution pipe between the pipe connecting flanges. A fixing flange is provided on the outside of the pipe connecting flange, and fixing bolts are provided at the connection between the fixing flange and the pipe connecting flange.

[0008] Preferably, a plurality of groups of water distribution pipe fixtures are arranged at the bottom of the anaerobic reaction tank, and a side of the water distribution pipe away from the annular water distribution pipe is movably connected with the water distribution pipe fixture.

[0009] Preferably, a positioning guide rope fixing piece is provided on the water distribution pipe fixer, and a positioning guide rope is provided through the water distribution pipe, one end of the positioning guide rope is connected to the positioning guide rope fixing piece, and a stainless steel ball is fixedly connected to the side of the positioning guide rope away from the positioning guide rope fixing piece, and the stainless steel ball is located on the sealing gasket.

[0010] Preferably, a control valve is provided on the side of the water distribution pipe close to the annular water distribution pipe, and a pressure detection component is provided on the side of the water distribution pipe close to the casing.

[0011] Preferably, a cleaning interface is provided on the water distribution pipe between the pressure detection component and the control valve, and a solenoid valve is provided on the cleaning interface.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. A control valve is set on the anaerobic water distribution pipe, which can not only control the opening and closing of the anaerobic water distribution pipe, but also adjust the flow rate of the sewage pipe in the anaerobic water distribution pipe. In addition, when a certain flow channel of the anaerobic water distribution pipe needs to be cleaned, maintained, disassembled, repaired or replaced, the control valve on the flow channel needs to be closed to stop water inlet. A cleaning interface and a pressure detection component are set behind the control valve of the anaerobic water distribution pipe. The change in the value of the pressure detection component can be used to determine whether the various flow channels of the anaerobic water distribution pipe are blocked and the degree of blockage. When a certain flow channel of the anaerobic water distribution pipe is blocked, the control valve can be closed, the solenoid valve of the cleaning interface can be opened, and then the high-pressure water gun can be connected to the cleaning interface to perform high-pressure flushing on the flow channel of the anaerobic water distribution pipe to dredge the anaerobic water distribution pipe to prevent the anaerobic water distribution pipe from being completely blocked and affecting the anaerobic water distribution effect.

[0014] 2. The water distribution pipe connection assembly is the key component for connecting the anaerobic water distribution pipe to the anaerobic reactor. By rotating the fixing bolts to connect the pipe to the fixed flange, it can not only enable the anaerobic water distribution pipe to penetrate into the anaerobic reactor and enter its interior, but also ensure that the connection part is well sealed and there is no sewage or gas leakage.

[0015] 3. The water distribution pipe reaches the bottom of the anaerobic reactor through the positioning guide rope. When the stainless steel pipe section of the anaerobic water distribution pipe is installed or removed, the positioning guide rope can ensure that the anaerobic water distribution pipe can be accurately connected to the water distribution pipe fixture or easily removed and pulled out of the anaerobic reactor without deviation or bending of the pipe section. The water distribution pipe can be effectively restricted by the water distribution fixture to prevent the water distribution pipe from swinging significantly. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 4 As shown, the utility model proposes an anaerobic reactor water distributor which is easy to maintain and clean, comprising an annular water distribution pipe 1, a water distribution pipe 2, a control valve 3, a pressure detection component 5, a water distribution pipe connecting component 6 and an anaerobic reaction tank 11, wherein a plurality of sleeves 7 are embedded on the upper side of the anaerobic reaction tank 11, and a water distribution pipe connecting component 6 is provided on the sleeve 7, the sleeve 7 is movably connected to the water distribution pipe 2 through the water distribution pipe connecting component 6, and the side of the water distribution pipe 2 away from the sleeve 7 is fixedly connected to the annular water distribution pipe 1.

[0024] In an optional embodiment, the water distribution pipe connection assembly 6 includes a fixing bolt 601, a fixing flange 602, a pipe connecting flange 603, a sealing gasket 604 and a stainless steel ball 605. The pipe connecting flange 603 is provided on the sleeve 7, and the sleeve 7 is movably connected to the water distribution pipe 2 through the pipe connecting flange 603, and a sealing gasket 604 is provided on the water distribution pipe 2 between the pipe connecting flanges 603. A fixing flange 602 is provided on the outer side of the pipe connecting flange 603, and a fixing bolt 601 is provided at the connection between the fixing flange 602 and the pipe connecting flange 603.

[0025] In an optional embodiment, a plurality of groups of water distribution pipe fixtures 9 are disposed at the bottom of the anaerobic reaction tank 11 , and a side of the water distribution pipe 2 away from the annular water distribution pipe 1 is movably connected to the water distribution pipe fixture 9 .

[0026] In an optional embodiment, a positioning guide rope fixing part 10 is provided on the water distribution pipe fixing part 9, and a positioning guide rope 8 is provided through the water distribution pipe 2, one end of the positioning guide rope 8 is connected to the positioning guide rope fixing part 10, and a stainless steel ball 605 is fixedly connected to the side of the positioning guide rope 8 away from the positioning guide rope fixing part 10, and the stainless steel ball 605 is located on the sealing gasket 604.

[0027] In an optional embodiment, a control valve 3 is provided on the side of the water distribution pipe 2 close to the annular water distribution pipe 1 , and a pressure detection component 5 is provided on the side of the water distribution pipe 2 close to the casing 7 .

[0028] In an optional embodiment, a cleaning interface 4 is provided on the water distribution pipe 2 between the pressure detection component 5 and the control valve 3 , and a solenoid valve is provided on the cleaning interface 4 .

[0029] The working principle of the utility model is as follows: when using the device, the sewage from the water inlet pump of the anaerobic reaction tank 11 first enters the annular water distributor 1, and the sewage is evenly distributed to the various flow channels of the anaerobic water distribution pipe 2 through the annular water distributor 1, and then enters the bottom of the anaerobic tank through the various flow channels of the anaerobic water distribution pipe 2, so as to achieve uniform distribution of the water inlet of the anaerobic reaction tank 11. The control valve 3 is arranged on the anaerobic water distribution pipe 2, which can not only control the opening and closing of the anaerobic water distribution pipe 2, but also adjust the flow rate of the sewage pipe in the anaerobic water distribution pipe 2. In addition, when the anaerobic water distribution pipe 2 is opened, the flow rate of the sewage pipe in the anaerobic water distribution pipe 2 is adjusted. When a certain flow channel of the water pipe 2 needs to be cleaned, maintained, disassembled, repaired, or replaced, the control valve 3 on the flow channel needs to be closed to stop water inlet. A cleaning interface 4 and a pressure detection component 5 are arranged behind the control valve 3 of the anaerobic water distribution pipe 2. Through the change of the value of the pressure detection component 5, it can be judged whether each flow channel of the anaerobic water distribution pipe 2 is blocked and the degree of blockage. When a certain flow channel of the anaerobic water distribution pipe 2 is blocked, the control valve 3 can be closed, the solenoid valve of the cleaning interface 4 can be opened, and then the high-pressure water gun can be connected to the cleaning interface 4 to clean the flow channel of the anaerobic water distribution pipe 2. High-pressure flushing is performed to clear the anaerobic water distribution pipe 2 to prevent the anaerobic water distribution pipe 2 from being completely blocked and affecting the anaerobic water distribution effect. The water distribution pipe connection assembly 6 is a key assembly for the anaerobic water distribution pipe 2 to connect to the anaerobic reaction tank 11. It is connected to the pipe connection flange 603 on the sleeve through a sealing gasket 604 to form a sealed pipe connection. At the same time, the fixing flange 602 is connected to the pipe connection flange 603 through a fixing bolt 601, so that the water distribution pipe connection assembly 6 is firmly installed on the anaerobic reaction tank 11, which can not only realize the anaerobic water distribution pipe 2 passing through the anaerobic reaction tank 11, but also can realize the anaerobic water distribution pipe 2 passing through the anaerobic reaction tank 11. The anaerobic water distribution pipe 2 can enter the anaerobic reaction tank 11 and the interior thereof, and can also ensure that the connection parts are well sealed without sewage or gas leakage. The water distribution pipe 2 reaches the bottom of the anaerobic reaction tank 11 through the positioning guide rope 8. When the stainless steel pipe section of the anaerobic water distribution pipe 2 is installed or disassembled, the positioning guide rope 8 can ensure that the anaerobic water distribution pipe 2 can be accurately connected to the water distribution pipe fixture 9 or easily disassembled and pulled out of the anaerobic reaction tank 11 without deviation or bending of the pipe section. The water distribution pipe 2 can be effectively restricted by the water distribution fixture 9 to prevent the water distribution pipe from swinging significantly.
