[0001] The utility model relates to the field of anaerobic systems, in particular to an anaerobic treatment system. Background Art

[0002] An anaerobic system is a water treatment system that uses water distribution pipes, water collection pipes, sludge pipes, and circulating pumps to treat wastewater in an anaerobic environment. Because the water entering the water distribution pipes often contains easily precipitated substances such as minerals and organic matter, scaling can easily form on the inner walls of the pipes after long-term use, leading to poor water flow and even blockage. Therefore, the pipes need to be cleaned.

[0003] However, the adapter in the water distribution pipe is a fixed connection with a metal elbow. When cleaning the pipe, the entire adapter needs to be removed, which is a large amount of work. At the same time, when installing it with the water distribution pipe, it is difficult to align the metal elbow with the water distribution pipe. The entire maintenance process is time-consuming, costly, and affects production. At the same time, in the existing water treatment system, the layout of the sludge discharge pipe fails to fully consider the sludge flow characteristics, resulting in difficulty in discharging the far-end sludge smoothly, and long-term accumulation forms blockages, further exacerbating the difficulty and cost of maintenance. Utility Model Content

[0004] The purpose of the utility model is to provide an anaerobic treatment system. By optimizing the structure of the adapter and the layout of the sludge discharge pipe, the anaerobic treatment system can solve the problems of inconvenient maintenance, high maintenance costs, long working hours, heavy workload after the water distribution pipe is blocked by scaling in the existing water treatment system, and poor remote sludge discharge and easy blockage caused by the unreasonable layout of the sludge discharge pipe.

[0007] In some embodiments, the height between the liquid outlet of the water distribution vertical pipe and the bottom of the anaerobic tank is 500 mm-800 mm.

[0008] In some embodiments, a movable flange is provided between the connecting horizontal pipe and the water distribution horizontal pipe, and between the connecting vertical pipe and the blind plate.

[0014] In summary, the present invention has the following beneficial effects:

[0015] The utility model changes the metal elbow into a three-way structure that connects the middle part of the connecting horizontal pipe and the vertical pipe vertically.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] refer to Figure 1-5 An anaerobic treatment system includes an anaerobic tank 1, an anaerobic circulation pump 2, a water distribution component 3, a water inlet component 4, a water collection component 5 and a sewage discharge component 6. The anaerobic tank 1, the anaerobic circulation pump 2, the water distribution component 3, the water inlet component 4, and the water collection component 5 together form a circulating pipeline for water treatment. This is the existing technology and will not be repeated here.

[0024] The water distribution assembly 3 includes a water distribution transverse pipe 31 and multiple water distribution vertical pipes 32. The water distribution transverse pipe 31 and the water distribution vertical pipe 32 can be made of PE pipes. The inner wall of the PE pipe is smooth, which can improve the fluidity of the internal liquid and reduce the risk of blockage; the water distribution transverse pipe 31 is connected to the outlet pipe of the anaerobic circulation pump 2. The water distribution transverse pipe 31 is arranged at the top of the anaerobic tank 1. The water distribution transverse pipe 31 is connected to multiple water distribution vertical pipes 32. The water distribution vertical pipes 32 are inserted into the anaerobic tank 1. The height between the liquid outlet of the water distribution vertical pipe 32 and the bottom of the anaerobic tank 1 can be 500mm-800mm to ensure uniform distribution of water flow. At the same time, the water flowing into the anaerobic tank has sufficient upward impact force after contacting the bottom wall. The water distribution vertical pipe 32 can be provided with a guide rope to set the drainage direction of the water distribution vertical pipe 32; an adapter 33 is provided between the water distribution transverse pipe 31 and the water distribution vertical pipe 32.

[0025] The adapter 33 includes a connecting transverse pipe 331 and a connecting vertical pipe 332. The connecting transverse pipe 331 is vertically connected to the middle of the connecting vertical pipe 332. The bottom of the connecting vertical pipe 332 is coaxially connected to the water distribution vertical pipe 32. The connecting transverse pipe 331 is coaxially connected to the water distribution transverse pipe 31. The top of the connecting vertical pipe 332 is blocked with a blind plate 333 to achieve a sealed connection between the adapter 33 and the water distribution transverse pipe 31 and the water distribution vertical pipe 32. When the pipeline is blocked, only the blind plate 333 needs to be removed to clean the pipeline. At the same time, repeated sealing when the connecting transverse pipe 331, the connecting vertical pipe 332 and the adapter 33 are avoided during installation. , thereby reducing the workload of disassembly and assembly, reducing maintenance time, and reducing the impact on production; a movable flange 334 is provided between the connecting horizontal pipe 331 and the water distribution horizontal pipe 31, and between the connecting vertical pipe 332 and the blind plate 333. During installation, the movable flange 334 can be rotated to improve the convenience of alignment between the mounting holes, thereby improving the efficiency of disassembly and assembly. The bolt assembly can be passed through the mounting holes on the movable flange 334 to fix the connecting horizontal pipe 331 to the water distribution horizontal pipe 31, and the connecting vertical pipe 332 is fixedly connected to the blind plate 333. The connection through the movable flange 334 is an existing technology and will not be repeated here.

[0026] In some embodiments, the anaerobic tank 1 includes a tank body 11, and a plurality of reserved pipes 12 are provided on the top wall of the tank body 11. A water distribution vertical pipe 32 is passed through the reserved pipe 12. A plurality of three-phase separators 13 are provided on the top wall of the tank body 11 to achieve separation of gas, liquid and solid. The middle part of the three-phase separator 13 can be connected to the gas branch pipe and the gas main pipe, and the generated gas can be transported to the gas recovery device to achieve recovery of the gas generated during the anaerobic treatment process; a water collecting component 5 is provided below the multiple three-phase separators 13, and the water collecting component 5 includes a water collecting main pipe 51. The water collecting main pipe 51 is provided below the three-phase separator 13. One end of the water collecting main pipe 51 passes through the tank body 11 and is connected to the water inlet pipe of the anaerobic circulation pump 2 to form a circulation, and the other end can protrude from the inner wall of the tank body 11 by 0-20 mm. This can avoid the inconvenience of cleaning caused by the pipe body extending into the tank body 11 being too long when the pipe body is blocked without affecting the water collection.

[0027] In some embodiments, the water inlet component 4 includes a water inlet pump 41, the water outlet of the water inlet pump 41 is connected to the anaerobic circulation pump 2, the water inlet of the water inlet pump 41 is connected to the heating tank 42, the heating tank 42 is connected to the water supply device, and the water supply device provides wastewater. After the wastewater is heated in the heating tank, it reaches the temperature required for the anaerobic treatment process to ensure the efficiency of the anaerobic treatment process.

[0028] The sewage discharge component includes an anaerobic sludge pump 61. The mud inlet of the anaerobic sludge pump 61 is connected to multiple mud discharge pipes 62. The mud discharge pipes 62 extend into the anaerobic tank 1. The mud outlet of the anaerobic sludge pump 61 is connected to the sludge tank. The anaerobic sludge pump 61 provides power to discharge the sludge at the outlet of the mud discharge pipe 62 into the sludge tank.

[0029] The distance between the multiple mud discharge pipes 62 and the side wall of the anaerobic tank 1 near the anaerobic mud discharge pump 61 is 0-10m, and the distance between the pipe openings of the multiple mud discharge pipes 62 and the bottom wall of the anaerobic tank 1 is 0.6-1.5m. The position coordinates of the pipe openings of the multiple mud discharge pipes 62 in the anaerobic tank 1 are not exactly the same. Specifically, refer to Figure 5 , take this surface as the coordinate plane, the connection point between the side wall and the bottom wall close to the anaerobic sludge discharge pump 61 as the coordinate origin, the length direction of the bottom wall as the horizontal coordinate, the height of the side wall as the vertical coordinate, there are 5 sludge discharge pipes 62, and the coordinate points of the pipe openings of the 5 sludge discharge pipes 62 are (0, 1.5), (6, 0.6), (10, 0.6), (10, 1.5), and (6, 1.5).

[0030] By setting sludge suction points with different position coordinates in the sludge layer, the sludge layer is fully covered by multiple sludge suction points, so that the sludge at the near and far ends of the sludge layer can be sucked away, thereby improving the fluidity within the sludge layer, thereby avoiding accumulation and blockage within the sludge layer and reducing maintenance difficulty and cost.

[0031] The specific working principle is as follows:

[0032] The anaerobic circulation pump 2 transports the mixed liquid through the water distribution horizontal pipe 31 to each water distribution vertical pipe 32. Since the liquid outlet of the water distribution vertical pipe 32 is designed to be a certain height above the bottom of the anaerobic tank 1, the mixed liquid impacts the bottom of the tank at a certain speed and diffuses upward, forming a uniform upwelling, which is conducive to the full contact and reaction between microorganisms and pollutants. After the anaerobic reaction, the mixed liquid is discharged through the gas branch pipe and the gas main pipe under the action of the three-phase separator 13. The gas and liquids fall into the area above the water receiving main pipe 51 and flow back to the anaerobic circulation pump 2 through the water receiving main pipe 51, forming a cycle; the sludge at the bottom of the anaerobic tank 1 is pumped out by the anaerobic sludge pump 61 through the sludge discharge pipe 62 and discharged into the sludge tank for further treatment. Since the layout of the sludge discharge pipe 62 takes into account the fluidity and sedimentation characteristics of the sludge, it can effectively reduce the risk of blockage.

[0033] When the water distribution assembly 3 is clogged, the blind plate 333 is opened and the water distribution assembly 3 can be cleaned by connecting the top of the vertical pipe 332, thereby improving the cleaning efficiency.

[0034] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
