Description

Anaerobic pulse water distribution device

technical field

The utility model relates to an anaerobic pulse water distribution device.

Background technique

Most of the existing UASB reactors adopt intermittent (pulse) water distribution, that is, a trough water distribution with one tube and one hole. The structure adopted in this water distribution method includes a pulse water distributor and a water distribution channel. A siphon main water distribution pipe distributes the water in the siphon bucket to each water distribution channel of the water distribution channel, and then distributes the water in each water distribution channel. The water distribution pipe above the pool surface enters the UASB reactor. The main disadvantages are as follows: 1. Because the civil engineering part is difficult to meet the technical requirements, it cannot achieve uniform water distribution, resulting in uneven water distribution. 2. With this structure, there is a phenomenon that scum accumulates and easily blocks the water distribution pipe.

Contents of the invention

The utility model aims at the above problems, and provides an anaerobic pulse water distribution device with simple structure, easy civil construction, uneven water distribution, and difficult blockage of plug water pipes.

In order to achieve the above purpose, the utility model adopts the following scheme. The utility model includes a water distributor, a water distribution channel, and a general water distribution pipe. The two ends of the main water distribution pipe are respectively arranged in the siphon bucket and the water distribution channel. The key point of the structure is that the water distribution channel includes a water inlet tank and four water distribution tanks. The bottom surface is at the same height as the upper end of the anaerobic distribution pipe, and the upper part of the water distribution tank is provided with an adjustable weir.

Beneficial effects of utility model

The utility model is an improvement on the existing water distribution device to ensure that the bottom height of the pulse water distribution device is equal to the upper end of the anaerobic water distribution pipe, and the insufficient part is filled with concrete; the siphon bucket of the pulse water distribution device uses the existing height and width , just increase the depth to two-thirds of the depth of the pulse water distributor; improve the original water distribution canal from one tube and one grid water distribution method to each water distribution canal is divided into one water inlet tank and four water distribution tanks, and in each The concrete grid of each water distribution tank is pre-embedded with steel plates to fix the adjustable weir, and the height of the weir is adjusted by bolts. The above scheme not only solves the accumulation of scum caused by the small amount of siphon, but also solves the phenomenon of uneven water distribution caused by civil construction, and has the following advantages:

1. Solve the problem of uneven water distribution caused by the water head, which is caused by the large water distribution near the inlet pipe end and the small water distribution at the far inlet pipe end, ensuring that the water distribution of each water distribution pipe is the same and the water distribution is more uniform;

2. There is no large waste of siphon volume, ensuring anaerobic hydraulic stirring intensity;

3. Increase the adjustable weir to reduce the construction technical requirements of civil works, thereby reducing the difficulty of construction.

Detailed ways

The utility model includes a water distributor 2, a water distribution channel 10, and a general water distribution pipe 6. The water distributor 2 is provided with a water distributor water inlet pipe 1 and an empty pipe 3. The water distributor 2 is provided with a siphon barrel 5 with a broken siphon tube 4. , the two ends of the total water distribution pipe 6 are respectively arranged in the siphon barrel 5 and the water distribution channel 10, the water distribution channel 10 includes a water inlet tank 12 and four water distribution tanks 11, and the anaerobic water distribution pipe 7 and the anaerobic water distribution channel are respectively arranged in the water distribution tanks 11 7 is installed in the pre-embedded pipe 8 li higher than the bottom of the water distribution tank 11 in the water distribution tank 11, the inner bottom surface of the water distributor 2 is equal to the upper end of the anaerobic water distribution pipe 7, and the top of the water distribution tank 11 is provided with an adjustable weir 9. The adjustable water weir 9 is installed on the water distribution tank 11 through the long holes on it and the bolts embedded in the upper wall of the water distribution tank 11 .

When in use, the front-end water enters the pulse water distributor 2 through the water distributor inlet pipe 1. When the liquid level in the water distributor 2 is higher than the top of the headquarters water pipe 6 in the siphon bucket 5, it begins to distribute water into the water distribution channel 10. When the water level in the water tank 12 is higher than the adjustable weir 9, distribute water to the four water distribution tanks 11 at the same time, and when the water level in the water distribution tank 11 rises to the upper end of the anaerobic water distribution pipe 7, the anaerobic water distribution pipe 7 begins to distribute water; When the liquid level in the water distributor 2 was lower than the bottom of the broken siphon 4, a pulse water distribution cycle ended. When the water distributor 2 is being maintained or cleaned, the water inside the water distributor 2 is drained into the anaerobic tank through the emptying pipe 3, and then the operation can be performed.
