Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment, specifically to a high-efficiency anaerobic unit water distribution device. Background Technology

[0002] Aquaculture wastewater is characterized by high COD, high BOD, high ammonia nitrogen, and high SS. Its treatment process generally requires anaerobic treatment methods. Anaerobic tanks have the characteristics of high organic load, high volume utilization rate, low energy consumption, and cost savings, making them one of the fastest-growing and most widely used anaerobic treatment processes.

[0003] The water distribution device in an anaerobic reactor needs to function as both water distribution and hydraulic mixing unit. However, existing water distribution systems are too simple in layout, making it difficult to ensure uniform water distribution and easily creating dead zones. Furthermore, when it's necessary to extend the wastewater retention time in the anaerobic tank, the tank volume needs to be increased. The height of the anaerobic tank generally cannot be significantly increased, resulting in an excessively large bottom area. This makes it difficult to ensure a sufficient upward flow velocity within the tank, leading to sludge accumulation at the bottom and extremely low mass transfer efficiency between sludge and wastewater, severely impacting the tank's treatment capacity. Utility Model Content

[0004] The purpose of this invention is to provide a highly efficient anaerobic unit water distribution device that can automatically impact the bottom sludge, addressing the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A high-efficiency anaerobic unit water distribution device includes a pool body, a water storage tank, a main water distribution pipe, branch water distribution pipes, an electric valve, a diffuser, and a control assembly. The water storage tank is fixedly installed on the top of the pool body, and an inlet pipe is connected to the top of the water storage tank. The main water distribution pipe is connected to the bottom of the water storage tank, and the top ends of several branch water distribution pipes are connected to the main water distribution pipe. The branch water distribution pipes are evenly distributed according to the bottom area of ​​the pool body. The bottom end of each branch water distribution pipe extends to the bottom of the pool body, and a diffuser is connected to the bottom end of each branch water distribution pipe. An electric valve is provided between each branch water distribution pipe and the main water distribution pipe, and the electric valve is connected to the control assembly.

[0007] Furthermore, the diffusion device includes a diffusion frame and a diffusion reflector; the top of the diffusion frame is provided with a connector, which is connected to the bottom of the water distribution branch pipe; the bottom of the diffusion frame is provided with a base, which is fixedly connected to the bottom of the pool body; the middle of the diffusion frame is provided with an open cavity, and the diffusion reflector is fixedly installed in the cavity.

[0008] Furthermore, the diffusion reflector is cone-shaped, spreading from the top to the bottom, so that the water flow in the water distribution branch pipe expands outward along the surface of the diffusion reflector.

[0009] Furthermore, the water storage tank is equipped with a liquid level detection module, which is connected to the control assembly.

[0010] This invention discloses a high-efficiency anaerobic unit water distribution device. It utilizes a storage tank to collect external clean water and, when sufficient water is available, automatically pulses water to the bottom of the tank, thereby dispersing the sludge and preventing its accumulation. This significantly improves the long-term treatment efficiency of the anaerobic unit. Furthermore, it features a simple structure and low energy consumption. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the structure of a high-efficiency anaerobic unit water distribution device provided by this utility model.

[0012] Figure 2 This is a schematic diagram of the diffusion device. Detailed Implementation

[0013] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0014] Example 1

[0015] like Figure 1 As shown, this utility model provides a high-efficiency anaerobic unit water distribution device, including a pool body 1, a water storage tank 2, a main water distribution pipe 3, branch water distribution pipes 4, an electric valve 5, a diffusion device 6, and a control assembly 7. The water storage tank 2 is fixedly installed on the top of the pool body 1, and an inlet pipe 21 is connected to the top of the water storage tank 2. The main water distribution pipe 3 is connected to the bottom of the water storage tank 2, and the top ends of several branch water distribution pipes 4 are connected to the main water distribution pipe 3. The branch water distribution pipes 4 are evenly distributed according to the bottom area of ​​the pool body 1. The bottom end of each branch water distribution pipe 4 extends to the bottom of the pool body 1, and a diffusion device 6 is connected to the bottom end of each branch water distribution pipe 4. An electric valve 5 is provided between each branch water distribution pipe 4 and the main water distribution pipe 3, and the electric valve 5 is connected to the control assembly 7.

[0016] Water is continuously supplied to the water storage tank 2 through the inlet pipe 21. When there is sufficient water in the tank 2, enough potential energy is stored. At this time, the electric valve 5 can be opened, allowing the water in the tank 2 to flow through the water distribution branch pipe 4 to the bottom of the pool 1, generating a water flow pulse. The water flow pulse can disperse the sludge at the bottom of the pool 1, preventing sludge accumulation and significantly improving the fluidity of the sludge and reaction efficiency.

[0017] It should be noted that, as an anaerobic unit, pool 1 may contain other devices, but since they are not relevant to this technology, these structures are omitted here.

[0018] like Figure 2As shown, specifically, the diffusion device 6 includes a diffusion frame 61 and a diffusion reflector 62; the top of the diffusion frame 61 is provided with a connector 611, which is connected to the bottom end of the water distribution branch pipe 4 through the connector 611; the bottom end of the diffusion frame 61 is provided with a base 612, which is fixedly connected to the bottom of the pool body 1 through the base 612; the middle part of the diffusion frame 61 is provided with a cavity 613 with open sides, and the diffusion reflector 62 is fixedly installed in the cavity 613.

[0019] Water in the water distribution branch pipe 4 flows into the top of the cavity 613 through the connector 611 and impacts the surface of the diffusion reflector plate 62 from top to bottom. Due to the reflection of the diffusion reflector plate 62, the water flow diffuses outward from all sides of the cavity 613 and sends a water flow pulse to the bottom of the pool body 1.

[0020] Specifically, the diffuser reflector 62 is cone-shaped, spreading from the top to the bottom, causing the water flow from the water distribution branch pipe 4 to expand outward along the surface of the diffuser reflector 62. The cone-shaped structure can cut the water flow in all directions, thereby guiding the water flow to impact in all directions and expanding the influence range of the water flow pulse.

[0021] To further improve automation and enhance intelligent collaboration, the water storage tank 2 is preferably equipped with a liquid level detection module, which is connected to the control assembly 7. The liquid level detection module can detect the water level in the water storage tank 2. When the water level reaches the target, the liquid level detection module will send a signal. Upon receiving the signal, the control assembly 7 will control the electric valve 5 to release a water flow pulse. After the water flow pulse is released, the liquid level in the water storage tank 2 drops, and the control assembly 7 controls the electric valve 5 to close, waiting for the next water discharge cycle.

[0022] This utility model provides a highly efficient water distribution device for an anaerobic unit. Optimized water distribution branch pipes 4 are evenly distributed at the bottom of the tank 1, utilizing the potential energy of the water to release water flow pulses at the bottom of the tank 1, dispersing sludge and preventing sludge accumulation. This device ensures long-term efficient operation of the anaerobic unit, improving equipment performance. Furthermore, it has a simple structure, requires no additional power source, and is highly efficient and environmentally friendly.

[0023] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
