Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to a combined adjustable anaerobic tank water distribution device. Background Art

[0002] As an effective treatment process for high-concentration wastewater, anaerobic treatment technology is widely used in various fields. When the water volume is large, several anaerobic reactors are often used in parallel. At this time, it is crucial to evenly distribute the water volume to each anaerobic reactor. Usually, pipes and flow meters are used to control the water volume, and manual operation of valves is used to achieve uniform distribution of the flow rate. However, due to the different distances between the pipes and each corresponding pool body, the losses are different, which will definitely cause certain differences in the distribution of the flow rate. And the errors brought by manual operation will inevitably bring uncertainties to the uniform distribution of the flow rate. After the wastewater is distributed to each pool body, since the area of each pool body is large, several water distribution perforated pipes are usually arranged in a ring shape and evenly distributed at the bottom of the pool body. The incoming water passes through a main pipe and then is distributed into each water distribution pipe. However, the travel lengths of the wastewater are different, and since the diameter of the water distribution pipes is generally small, they are easily blocked. Therefore, the purpose of uniform water distribution cannot be guaranteed.

[0003] The patent with the patent number CN202323017005.9 discloses an anaerobic reactor water distribution device, including: a water distribution cylinder, a water inlet pipe and a water outlet baffle installed at the bottom of the anaerobic reactor; the water flowing out of the water inlet pipe flows into the water distribution cylinder, and a plurality of obliquely cut strip-shaped water outlet holes are evenly distributed on the side wall of the water distribution cylinder body of the water distribution cylinder, and the water outlet swirling directions of all the obliquely cut strip-shaped water outlet holes are the same; a water outlet baffle is provided at each obliquely cut strip-shaped water outlet hole. The water distribution device of the utility model can make the incoming water form a uniform swirl with the water distribution cylinder as the center, ensuring stable and uniform water distribution; at the same time, the water distribution swirl can form a uniform disturbance in the anaerobic reactor, making the sludge and wastewater fully mixed, preventing sludge sedimentation, and using hydraulic swirl to complete the stirring effect, saving energy; at the same time, the water distribution device has a simple structure and is not easily blocked. Although the problem of sludge sedimentation is solved, it is not easy to observe, and it is also impossible to control and adjust the water distribution flow rates on both sides, and it is not conducive to replacement. Summary of the Invention

[0004] The comparative document solves the problem of unevenness. What we need to solve are the problems that the comparative document cannot solve, or has better effects than it.

[0005] The purpose of the utility model is to solve the problems that the water distribution flow rates on both sides of the baffle cannot be controlled and it is not conducive to replacement. The technical solutions are as follows:

[0006] A combined adjustable anaerobic tank water distribution device, comprising a buffer tank 1, a water distribution plate 2, a diversion plate 3, a water distribution channel 4, an adjustment weir 5, a water distribution area 6, and a water distribution pipe 7. It is characterized in that the buffer tank 1 is arranged at the center of the whole device. Diversion plates 3 are arranged on both sides of the buffer tank 1. A liftable water distribution plate 2 is arranged outside the diversion plates 3. The water distribution channels 4 are respectively connected to both ends of the buffer tank 1. Adjustment weirs are respectively configured on both sides of the water distribution channels 4. The water distribution channel 4 is divided into several water distribution areas 6, and a water distribution pipe 7 is configured in each water distribution area 6. Drain pipes 11 are respectively arranged at the bottom of the buffer tank 1 and at the bottoms of the water distribution channels on both sides.

[0007] The water distribution plate 2 is connected to the diversion plate 3 through a rail groove 9.

[0008] The buffer tank 1 is a square tank body.

[0009] The top of the water distribution channel 4 is covered with a movable cover plate.

[0010] A swivel joint 10 is installed on the water distribution pipe 7.

[0011] The beneficial technical effects of the present utility model: The combined adjustable anaerobic tank water distribution device is placed at the top of the anaerobic tank body in the width direction of the whole anaerobic tank body. The buffer tank is a square tank body. Wastewater enters from the middle part of the buffer tank. Water distribution plates and diversion plates are respectively configured on both sides inside the tank body. The water distribution plate is liftable. By controlling the lifting plate, the water distribution flow on both sides can be adjusted, and the single-side operation of the tank body can also be controlled. The diversion plate serves the purpose of buffering the impact of the incoming water. The water distribution channels on both sides of the buffer tank are rectangular and are divided into several regions according to the number of water distribution pipes. Each region is not connected to each other. The incoming water enters the water distribution channel, and the water volume entering each water distribution area is controlled by the adjustable weir plates on both sides of the channel. A water distribution pipe is arranged in each water distribution area, and the water distribution pipe directly extends to the water distribution point at the bottom of the tank, realizing single-pipe water distribution in a single region, making the water distribution more uniform and not affected by other partitions. The top of the water distribution channel is covered with a movable cover plate, and it can be checked daily by opening the cover to see if there are floating objects in the incoming water, whether the water distribution pipes are blocked, or whether the water distribution is uneven, etc. The connection between the water distribution pipes in the channel and the water distribution pipes in the tank adopts a non-fixed connection. When it is observed through the water distribution channel that there is a blockage in the bottom water distribution pipe, the connection can be opened in time for cleaning.

Among them, the buffer tank 1 is arranged at the center of the whole device. Flow guide plates 3 are arranged on both sides of the buffer tank 1. A liftable water distribution plate 2 is arranged outside the flow guide plates 3. The water distribution channels 4 are respectively connected to both ends of the buffer tank 1. Regulating weirs are respectively configured on both sides of the water distribution channels 4. The water distribution channels 4 are divided into several water distribution areas 6. Each water distribution area 6 is configured with a water distribution pipe 7. The top of the water pipe nozzle is 30 mm lower than the notch of the regulating weir plate. DN40 stainless steel pipes are used. The bottom penetrates through the bottom plate of the water distribution area 6 and is firmly welded to the tank bottom.
