Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a point-type water distributor for an anti-clogging IC reactor. Background Technology

[0002] The IC reactor is a new generation of high-efficiency anaerobic reactor, also known as an internal circulation anaerobic reactor, consisting of two UASB reactors connected in series. It comprises two reaction chambers, upper and lower, in which wastewater flows from bottom to top, and the purified water flows out from the top of the reactor.

[0003] The IC reactor is equipped with a point-type water distributor to evenly distribute the incoming water, ensuring uniform mixing of the water flow inside the reactor and improving treatment efficiency.

[0004] However, due to the large amount of impurities and particulate matter in the sewage, the nozzles of the point-type water distributor are prone to clogging during use; in addition, impurities are prone to accumulate at the connection between the main pipe and the branch pipe or at the bends of the water distributor.

[0005] Both of the above situations will cause the water flow of the point-type water distributor to be obstructed, affecting the treatment effect. In addition, the existing point-type water distributors generally treat impurities by positive pressure flushing. This treatment method can only wash away some impurities and particles. The remaining part will be directly attached to the nozzle due to the positive pressure. After a period of accumulation, it is necessary to stop production and clean the IC reactor manually, which affects production operation and increases maintenance costs. Utility Model Content

[0006] In view of this, this utility model proposes a clog-resistant point-type water distributor for IC reactors to solve the problem that water distributors in the prior art are prone to clogging, cannot be cleaned properly, and require shutdown for cleaning, thus affecting production operations.

The water distribution structure includes a water distribution main pipe, which extends out of the IC reactor and connects to an inlet pipe, which is connected to a filter. Both the water distribution main pipe and the inlet pipe are equipped with backwashing structures. When the backwashing structure of the water distribution main pipe is opened, there is a pressure difference between the IC reactor and the water distribution main pipe, and the pressure in the IC reactor is greater than the pressure in the water distribution main pipe.

[0009] Based on the above technical solutions, preferably, the main water distribution pipe is connected to several branch pipes, each branch pipe is equipped with several nozzles, and each nozzle is equipped with a water distribution cap.

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] See Figure 1 The anti-clogging IC reactor point water distributor of this utility model includes a water distribution structure installed in the IC reaction tank 4. The water distribution structure includes a water distribution main pipe 1, which extends out of the IC reaction tank 4 and is connected to a water inlet pipe 2. The water inlet pipe 2 is connected to a filter 3, and the end of the water inlet pipe 2 is connected to a water inlet pump.

[0026] Both the main water distribution pipe 1 and the inlet pipe 2 are equipped with backwashing structures. When the backwashing structure of the main water distribution pipe 1 is opened, there is a pressure difference between the IC reaction tank 4 and the main water distribution pipe 1, and the pressure of the IC reaction tank 4 is 1-2 kg greater than the pressure of the main water distribution pipe 1.

[0027] In this invention, the water distribution structure is set in 2-4 groups, and the structure of each group is the same.

[0028] Furthermore, the main water distribution pipe 1 is connected to several branch pipes 11 via a first flange 15, facilitating cleaning and replacement of the branch pipes 11 during tank cleaning; each branch pipe 11 is equipped with several nozzles 12, see [link to documentation]. Figure 2 Each nozzle 12 is equipped with a water distribution cap 13; water in the main water distribution pipe 1 passes through the branch pipe 11 and is sprayed from the nozzle 12 into the IC reaction tank 4, and is evenly sprayed through the water distribution cap 13. One end of the main water distribution pipe 1 extends out of the IC reaction tank 4 and is connected to the first vent ball valve 14, and the other end of the main water distribution pipe 1 extends out of the IC reaction tank 4 and is connected to the inlet pipe 2. A second valve 26 is provided at the connection between the main water distribution pipe 1 and the inlet pipe 2.

[0029] The inlet pipe 2 is connected to the backwash pipe 21, and the backwash pipe 21 is equipped with a first valve 22. The inlet pipe 2 is also equipped with a flow meter 23, a pressure gauge 24, and a second drain ball valve 25. Through the flow meter 23 and the pressure gauge 24, it is possible to monitor in real time whether the main water distribution pipe 1 and the branch pipe 11 are blocked. If a blockage occurs, the flow rate data in the flow meter 23 will decrease, and the pressure data in the pressure gauge 24 will increase.

[0030] The filter 3 has an inlet 31 at one end and an outlet 32 ​​at the other end; the filter 3 is also equipped with a backwash drain valve 33; a fine mesh filter element 34 is installed inside the filter 3 through a second flange 36, and a blind flange 35 is installed on the fine mesh filter element 34. The blind flange 35 facilitates the cleaning of debris growing inside the fine mesh filter element 34. The filter 3 and the fine mesh filter element 34 are connected by the second flange 36 and can be disassembled to clean debris that is difficult to remove from the fine mesh filter element 34.

[0031] In this invention, the backwashing structure on the main water distribution pipe 1 includes a first vent ball valve 14 and a second vent ball valve 25. When the backwashing structure of the main water distribution pipe 1 is opened, a pressure difference exists between the IC reaction tank 4 and the main water distribution pipe 1. This means that when the first vent ball valve 14 and the second vent ball valve 25 are open, a pressure difference exists between the IC reaction tank 4 and the main water distribution pipe 1. The backwashing structure on the inlet pipe 2 includes a second vent ball valve 25, a backwash drain valve 33, and a backwash pipe 21.

[0032] After the IC reaction vessel 4 has been used for a period of time, at the corner of the main water distribution pipe 1 or at the corner where the main water distribution pipe 1 connects to the branch pipe 11 ( Figure 1 (at point a in the text), and at the corner where the branch pipe 11 connects to the nozzle 12 ( Figure 2 At point b in the diagram, and on the water distribution cap 13, many impurities will be retained. In the prior art, the pressure in the IC reaction tank 4 is the same as the pressure in the main water distribution pipe 1 and the branch pipe 11, or the pressure in the IC reaction tank 4 is less than the pressure in the main water distribution pipe 1 and the branch pipe 11, which causes impurities to not be cleaned properly or even to stick to the water distribution cap 13.

[0033] When the water distribution structure is in normal water intake, the pressure of the water inlet pump is greater than the pressure in IC reaction tank 4, so that the water distribution structure can normally deliver water to IC reaction tank 4.

[0034] When the water distribution structure is working, firstly, the filter 3 mainly plays the role of preventing clogging. The fine mesh filter element 34 filters out large particles or blocky impurities in the sewage to prevent clogging of the nozzle 12 and the water distribution cap 13.

[0035] When flow meter 23 and pressure gauge 24 detect blockage, shut off the inlet pump:

[0036] First, clean the main water distribution pipe 1 or branch pipe 11. At the same time, open the first venting ball valve 14 and the second venting ball valve 25 (the second valve 26 is in the open state). The pressure in the main water distribution pipe 1 and branch pipe 11 drops instantly, making the pressure in the IC reaction tank 4 1-2 kg greater than the pressure in the main water distribution pipe 1 and branch pipe 11. Under the action of negative pressure, impurities in the main water distribution pipe 1 and branch pipe 11 can be instantly backflushed out of the pipe through the first venting ball valve 14 and the second venting ball valve 25.

[0037] Then, close the second valve 26, and simultaneously open the second drain ball valve 25 and the backwash drain valve 33. Then open the first valve 22 on the backwash pipe 21 to backwash the inlet pipe 2 and the fine screen filter element 34. By controlling the water pressure in the backwash pipe 21 to be 1-2 kg higher than the water pressure in the inlet pipe 2, the impurities in the inlet pipe 2 and the fine screen filter element 34 are discharged in reverse from the second drain ball valve 25 and the backwash drain valve 33, and the discharge is relatively thorough.

[0038] Finally, if the user believes that the fine mesh filter element 34 still needs to be cleaned, the filter 3 and the fine mesh filter element 34 can be disassembled through the second flange 36 to clean the impurities that are not easy to remove from the fine mesh filter element 34. During the cleaning process, the blind flange 35 on the fine mesh filter element 34 is opened and the impurities are discharged from the blind flange 35.

[0039] In addition, since the water distribution structure of this utility model is set in multiple groups, when one group of water distribution structures is backwashed to remove the retained impurities, the other water distribution structures can still work normally without stopping production or affecting the production progress.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
