[0002] Currently, upflow anaerobic sludge blanket reactors are widely used anaerobic biological devices in the field of wastewater treatment. Among them, the three-phase separator, as an important component of the upflow anaerobic reactor, plays a key role in achieving high treatment efficiency. How to achieve efficient separation of gas, sludge, and water phases, ensure that the gas is fully released and collected before entering the settling zone, effectively separate the sludge-water mixture in the sedimentation zone, stabilize the effluent quality, and ensure that the sludge forms particles and settles sufficiently are important factors restricting the application of existing technologies in complex water systems.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 The present invention provides an embodiment of a high-efficiency three-phase separation device based on a small-diameter upflow anaerobic reactor, comprising a shell 2, which is cylindrical in shape and provides a closed space for the reaction and separation process of the entire device. A water inlet pipe 1 is fixedly connected inside the shell 2. A flow guiding component is provided inside the shell 2 to guide the orderly flow of the gas-slurry-water mixture and improve the three-phase separation efficiency. A water distribution component is provided inside the shell 2.

[0029] The flow guiding component includes a flow guiding block 3, whose sidewalls are fixedly connected to the inside of the shell 2. The flow guiding block 3 has a conical structure and a smooth surface, which can guide the sewage and gas-sludge-water mixture to diffuse and flow in all directions, avoiding turbulence caused by direct water flow and creating an orderly flow field environment for subsequent separation. Symmetrical flow guiding inclined plates 4 with a large surface area are fixedly connected inside the shell 2, which can guide the rising gas, promote the separation of gas and sludge-water, and slow down the rising speed of the sludge-water mixture, providing favorable conditions for sludge sedimentation. Multiple gas collection chambers 5 are arranged in a ring array on the inner wall of the shell 2, which can fully... The system captures rising gas from different directions to prevent gas escape and improve gas collection efficiency. Multiple gas outlets 6 are located inside the housing 2 to centrally discharge the collected gas. A sealing cover 7 is installed inside the housing 2 to prevent gas leakage during collection and transportation, ensuring the integrity of the gas collection. An odor collection pipe 8 is installed inside the housing 2, extending one end to the area where odor is generated, to collect and treat the odor generated during the separation process in a timely manner, preventing odor pollution of the environment. Symmetrical water outlet tanks 9 are installed inside the housing 2 to efficiently collect the clear water after sedimentation and separation, ensuring smooth water flow. A gas delivery pipe 10 is fixedly connected inside the housing 2.

[0030] Reference Figure 1 and Figure 4 The water distribution assembly includes multiple water supply pipes 17 and nozzles 18. The multiple water supply pipes 17 are all installed inside the housing 2, using corrosion-resistant materials to adapt to the sewage environment inside the housing 2. Their diameter and length are rationally designed according to the water distribution area to ensure uniform water delivery. Multiple nozzles 18 are fixedly connected to the output ends of the multiple water supply pipes 17, spraying water in the form of fine droplets to designated areas, improving water replenishment and cleaning effects. A support base 11 is fixedly connected to the outer wall of the housing 2, and a water tank 12 is fixedly connected inside the support base 11. A water injection pipe 13 is fixedly connected to one end of the water tank 12. It can be connected to an external water source to replenish water tank 12 in a timely manner, ensuring a continuous water supply to the water distribution component. The outer wall of water tank 12 is equipped with multiple valves 14, and the output ends of multiple valves 14 are fixedly connected to connecting pipes 15. Each valve 14 can independently control the water flow of the corresponding connecting pipe 15. The water flow can be precisely controlled by controlling the opening degree. Multiple T-joints 16 are provided between multiple connecting pipes 15. Multiple connecting pipes 15 are connected to water supply pipes 17 through multiple T-joints 16, which can flexibly distribute water to different water supply pipes 17 to achieve precise water distribution in different areas.

[0031] Working principle: When using this high-efficiency three-phase separation device based on a small-diameter upflow anaerobic reactor, the wastewater first enters the reaction system inside the shell 2 through the inlet pipe 1, and undergoes anaerobic reaction to produce a gas-sludge-water mixture. Subsequently, the flow guiding component operates, the flow guiding block 3 guides the direction of water flow, and the left and right symmetrical flow guiding inclined plates 4 assist the orderly flow of the gas-sludge-water mixture. Utilizing the "layered flow guiding effect", the gas with the lowest density flows rapidly upward along the inclined surface of the flow guiding inclined plate 4 and converges to multiple gas collection chambers 5 arranged in a ring array on the inner wall of the shell 2. The gas is collected through the gas outlet 6 and the gas delivery pipe 10, and is sealed with the cover 7. At the same time, the odor collection pipe 8 surrounding the sedimentation zone captures the trace amount of odor released by the sludge during separation by means of the slight pressure difference with the gas collection chamber 5, thus preventing the escape and pollution.

[0032] The mud-water mixture adopts a radial flow pattern with peripheral inlet and outlet. Under the action of the guide plate 4 and guide block 3, it enters the sedimentation zone. The symmetrical outlet trough 9 forms a "ring radial flow + multi-point confluence" structure. With the central flow obstruction of the guide block 3, the mud-water forms a radial slow settling environment in the sedimentation zone, so that the water flow speed is slow at first and then stable. The sludge particles settle due to gravity and automatically flow back to the reaction zone through the return gap of the guide plate and guide block. The clean water overflows and is discharged evenly along the outlet trough 9. The guide plate 4 and the sedimentation zone enable the sludge to settle back and forth twice, achieving efficient sedimentation of sludge particles and stable effluent quality.

[0033] When the device needs to replenish water to maintain stable internal water quality during operation, the operator can precisely control the opening and closing of each valve 14 according to actual needs, and distribute the water in the water tank 12 to the connecting pipe 15 in an orderly manner. The connecting pipe 15 cooperates with multiple tee joints 16 to flow water to different water supply pipes 17. Finally, the water is sprayed evenly into the corresponding area inside the shell 2 through the nozzle 18 at the end of the water supply pipe 17. This can clean the sedimentation area, replenish the water in the reaction area, or adjust the internal water flow concentration and distribution, ensuring a stable reaction environment inside the device and assisting the three-phase separation process to proceed efficiently and continuously.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
