Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a water distribution device for an anaerobic biochemical reactor. Background Art

[0002] Currently, in anaerobic treatment systems, the widely used water distributors often face some technical challenges. Firstly, these water distributors often show unevenness in water flow distribution, which leads to a decline in treatment efficiency because not all reaction zones can receive appropriate water flow supply. Secondly, the control of flow velocity and flow rate is also not precise enough, which greatly affects the stability and treatment effect of the system. Finally, since the small pipes in the water distribution system are easily blocked by substances such as sludge, this not only increases the difficulty of maintenance but also reduces the overall efficiency of the system. In view of these problems, there is an urgent need to develop a new type of water distributor that should be able to more precisely control the water flow to ensure that each part of the reactor can obtain an ideal water flow distribution, thereby improving the performance and reliability of the entire anaerobic treatment system.

[0003] In the patent "Anaerobic Reactor" (publication number CN215855340U, hereinafter referred to as the prior art 1), an anaerobic reactor is disclosed. The prior art 1 realizes the anaerobic treatment of sludge through the anaerobic reactor, solves the problem of pipeline blockage caused by sludge calcification, ensures the stability and balance of long-term water distribution, and improves production efficiency. The reactor includes a reactor body, a water inlet system, and a three-phase separation system. The pressure change in the water distribution branch pipe is observed through a pressure gauge to judge the situation of sludge calcification and pipeline blockage. The water distribution branch pipe is closed by an electromagnetic valve to increase the scouring impact force on the blocked pipeline, so as to dredge the blocked water distribution branch pipe through hydraulic action.

[0004] In the prior art 1, the water distribution branch pipe of the blocked biochemical reactor is dredged by closing the water distribution branch pipe with an electromagnetic valve to increase the scouring impact force on the blocked pipeline and using hydraulic impact to dredge the pipeline. Although the prior art 1 controls the closing of the water distribution branch pipe through an electromagnetic valve and uses hydraulic impact to try to dredge the blocked water distribution branch pipe of the biochemical reactor and uses hydraulic impact to dredge the pipeline, since the water source used for impact cannot be discharged, the impact effect may not be achieved, and there may be a risk of pipeline rupture after water volume blockage. Summary of the Utility Model

[0026] Embodiment 1

[0027] Please refer to Figure 1 , the embodiments of the present utility model provide a novel anaerobic biochemical reactor water distribution device, the purpose of which is to effectively address the many challenges encountered in the current use of biochemical water distributors. These problems mainly include uneven water distribution, that is, the water is unevenly distributed in the reactor, resulting in significant differences in water quality conditions in some areas compared to other areas. It is difficult to control the flow rate and flow volume. Since the existing equipment cannot accurately adjust the water flow rate and flow volume, it is difficult to ensure that the biochemical reactions everywhere in the reactor are in the best state. In addition, small-pipe water distribution is easily blocked by sludge, which not only restricts the water flow but may also cause the pipeline to burst, thus affecting the normal operation of the entire anaerobic biochemical reactor. The water distributor in this embodiment aims to solve these problems by optimizing the water distribution system design, improving the uniform water distribution ability of the equipment, enhancing the controllability of the flow rate and flow volume, and using anti-blocking materials, etc., so as to improve the efficiency and stability of the anaerobic biochemical reactor.

[0028] Please refer to Figure 2, a new type of anaerobic biochemical reactor water distribution device includes a water distributor main body 100. The water distributor main body 100 is a core part, inside which there are water distribution components and a wastewater treatment space. This water distribution component is responsible for evenly distributing the wastewater in the reactor to ensure the full mixing and reaction of the wastewater. At the same time, the wastewater treatment space provides a suitable environment for microorganisms to carry out effective anaerobic biological treatment.

[0029] The water distributor has a unique design, and a special reaction chamber 110 is formed inside its main body structure. At the bottom of this reaction chamber 110, there is a water outlet 120, which is connected to a water outlet pipe 121. The end of this water outlet pipe 121 is equipped with a water outlet valve 122. By adjusting the opening degree of this water outlet valve 122, the water distribution flow rate and instantaneous speed can be controlled.

[0030] When a large amount of water needs to be distributed, the water outlet valve 122 can be fully opened. At this time, the water distribution flow rate will increase accordingly. However, since the water distribution rate is determined by the design of the water distributor, even if the valve opening is large, the instantaneous water distribution speed will not be too high to ensure the uniformity and stability of water distribution. On the contrary, when the water distribution amount needs to be reduced, the water outlet valve 122 can be partially closed. In this way, the water distribution flow rate will decrease accordingly, and the instantaneous water distribution speed will also remain at a low level to avoid affecting the water distribution effect due to too fast water flow. Through this design, whether it is a large amount of water distribution or a small amount of water distribution, the opening degree of the water outlet valve 122 can be adjusted to achieve precise control of the water distribution flow rate and instantaneous speed, making the water distribution process more intelligent and automated, and improving the efficiency and accuracy of water distribution.

[0031] Please refer to Figure 1, one end of the water outlet pipe 121 disposed in the reaction chamber 110 is open; one end of the water outlet pipe 121 disposed in the reaction chamber 110 is covered by a bell cover 130; there is a gap between the bell cover 130 and the water outlet pipe 121; the bell cover 130 is provided with a water outlet 120 at one end close to the bottom of the reaction chamber 110; the water outlet 120 includes a first water outlet 120 and a second water outlet 120; the first water outlet 120 and the second water outlet 120 are respectively disposed on both sides of the bell cover 130; the bell cover 130 is communicated with the reaction chamber 110 through the first water outlet 120 and the second water outlet 120. The gap between the bell cover 130 and the water outlet pipe 121 is a waste water flow channel 133; the waste water enters the waste water flow channel 133 through the first water outlet 120 and the second water outlet 120, and the water distribution is controlled by a water outlet valve 122 provided at the water outlet pipe 121. The waste water forms a siphon effect among the reaction chamber 110, the first water outlet 120, the second water outlet 120, the waste water flow channel 133 and the water outlet pipe 121.

[0032] Please refer to Figure 1 , through a specific structure of the water outlet pipe 121 and the bell cover 130, the reaction chamber 110 realizes the effective treatment and control of waste water. Specifically, one end of the reaction chamber 110 is provided with a water outlet pipe 121, and one end of the water outlet pipe 121 is open to facilitate the discharge of waste water. In order to better protect the water outlet pipe 121, one end of the water outlet pipe 121 is covered by a bell cover 130, which not only plays a protective role but also prevents the overflow of waste water.

[0033] Please refer to Figure 1 , in this structure, there is a certain gap between the bell cover 130 and the water outlet pipe 121, and this gap forms a waste water flow channel 133. The waste water enters the waste water flow channel 133 through the water outlet 120 at one end of the bell cover 130 close to the bottom of the reaction chamber 110. This water outlet 120 includes two parts, namely the first water outlet 120 and the second water outlet 120, which are respectively located on both sides of the bell cover 130 to ensure that the waste water can flow into the waste water flow channel 133 evenly. At the same time, the bell cover 130 is connected to the reaction chamber 110 through the first water outlet 120 and the second water outlet 120. In this way, the waste water can form a siphon effect among the reaction chamber 110, the first water outlet 120, the second water outlet 120, the waste water flow channel 133 and the water outlet pipe 121, improving the flow efficiency of the waste water. In order to better control the flow of waste water, a water outlet valve 122 is also provided inside the bell cover 130. By opening and closing the water outlet valve 122, the outflow speed and flow rate of the waste water can be controlled, so as to achieve precise control of waste water treatment.

[0034] Please refer to Figure 2, through the water outlet valve 122, we can only control the flow rate of the discharged water. Further, the outside of the water distributor main body 100 is equipped with a first air pipe 141 and a second air pipe 142. The first air pipe 141 is connected to the reaction chamber 110 through a top cover 150 provided at the top of the water distributor main body 100, while the second air pipe 142 is internally connected to the inside of the bell jar 130 through a connecting pipe 143. These two air pipes are interconnected, and a first air valve 144 and a second air valve 145 are respectively provided on them. By adjusting the opening degree of the first air valve 144, we can control the instantaneous speed of water distribution. The first air valve 144 is an intake and exhaust valve, and the second air valve 145 is an intake valve.

[0035] After a siphon effect is generated in the reaction chamber 110, there will be a certain degree of vacuum in the reaction chamber 110. If there is no air in the reaction chamber 110, the wastewater cannot be discharged. The first air pipe 141 is connected to the reaction chamber 110, and by opening the first air valve 144, we can supply gas to the reaction chamber 110. By controlling the opening and closing degree of the first air valve 144, we can control the discharge speed of the wastewater.

[0036] When the opening of the first air valve 144 is small, the amount of air entering the reaction chamber 110 is small, the pressure on the wastewater is small, and thus the discharge speed of the wastewater will also be low. On the contrary, when the opening of the first air valve 144 is large, the amount of air entering the reaction chamber 110 is large, the pressure on the wastewater is large, resulting in a higher discharge speed of the wastewater.

[0037] Further, by controlling the instantaneous discharge speed of the wastewater, when the opening of the water outlet valve 122 is small, the discharged wastewater will become very rapid, which will generate an impact force on the inside of the small pipe, thereby effectively discharging the sludge and impurities inside the small pipe. This process helps to remove the dirt in the pipeline, keep the water quality clean, and at the same time is conducive to the smoothness of the pipeline and reduces the risk of blockage. By controlling the wastewater discharge speed, we can better maintain the normal operation of the water treatment system and ensure the sustainable utilization of water resources. In addition, this method also helps to improve the water treatment efficiency, reduce the maintenance cost, and has a positive significance for environmental protection. In short, by precisely controlling the wastewater discharge speed, we can optimize the internal environment of the pipeline and improve the performance and stability of the entire water treatment system.

[0038] Please refer to Figure 2, in the design of the biochemical reactor, safety and convenience are particularly considered. Therefore, a vent port 160 is equipped at the bottom inside the reaction chamber 110. This vent port 160 plays a crucial role. It can enable the timely discharge of the gas accumulated in the reaction chamber 110, thus ensuring the safety of the reaction process. To achieve this function, a dedicated vent pipe 161 is provided near the vent port 160. This pipe not only serves to guide the gas but also is equipped with a third gas valve 146. This gas valve can precisely control the gas flow, prevent gas backflow, and ensure the stable operation of the system. In addition, this vent pipe 161 is also connected to the second gas pipe 142. In this way, when gas needs to be discharged, the gas can smoothly discharge from the reaction chamber 110, and when it is not needed, it can be effectively sealed to avoid gas waste and environmental pollution. This design reflects the humanization and technologicalization in the design of the biochemical reactor, which not only improves work efficiency but also increases safety and reliability.

[0039] Please refer to Figure 1 and Figure 3 , the water outlet valve 122 is connected to a water delivery pipe 123. The water distributor main body 100 completes the water distribution operation through the water delivery pipe 123 and discharges the wastewater into the water distribution area 200. The water outlet valve 122 is connected to the water outlet pipe 121 through a water delivery pipe 123, and this pipe is responsible for outputting water from the water distributor main body 100. In the water distributor main body 100, through this water delivery pipe 123, water is evenly distributed to each part of the discharged water, thus completing the water distribution operation. This process ensures that water can accurately reach the places where it is needed to meet various irrigation or water supply requirements. In this way, the water distributor can work effectively and provide a convenient solution for agricultural production, urban greening, or other occasions that require water.

[0040] The junction of the water outlet pipe 121 and the water outlet 120 is set in a sealed manner. The bell cover 130 covers the water outlet pipe 121 and is joined to the bottom of the reaction chamber 110, and the junction of the bell cover 130 and the reaction chamber 110 is set in a sealed manner. The top of the water distributor main body 100 is provided with a detachable top cover 150, and when the top cover 150 is joined to the water distributor main body 100, it is set in a sealed manner.

[0041] Please refer to Figure 1, the connection between the water outlet pipe 121 and the water outlet 120 is designed in a sealed manner to ensure that water flow does not leak, improving the safety and reliability of the system. The bell cover 130 completely covers the water outlet pipe 121 and is tightly joined to the bottom of the reaction chamber 110 to form a sealed space, preventing external impurities from entering the pipe and ensuring pure water quality. At the same time, the joint between the bell cover 130 and the reaction chamber 110 is also set in a sealed manner to prevent gas and moisture leakage and maintain the pressure stability of the reaction chamber 110.

[0042] The top of the water distributor main body 100 is designed with a detachable top cover 150, which is convenient for users to carry out maintenance and cleaning. When the top cover 150 is joined to the water distributor main body 100, it is also set in a sealed manner to ensure that the water inside the water tank is not contaminated externally, and at the same time, it can prevent water evaporation and overflow. This design not only improves the service life of the equipment but also ensures the safety and hygiene of water quality. Generally speaking, through a series of sealed designs, the present invention ensures the safe, reliable, and efficient operation of the system.

[0043] Please refer to Figure 2 , the first valve opens, the second air valve 145 closes, the water outlet valve 122 opens, and the wastewater passes through the first water outlet 120 and the second water outlet 120 in the reaction chamber 110 through the wastewater flow channel 133 and is discharged by the water supply pipe 123. In this equipment, the first valve is started first. At this time, the second air valve 145 will be in a closed state. Immediately afterwards, the water outlet valve 122 will also be opened. At this time, the wastewater will flow in the reaction chamber 110, pass through the first water outlet 120 and the second water outlet 120, flow along the wastewater flow channel 133, and finally be discharged by the water supply pipe 123. This process can achieve efficient water flow control and wastewater discharge.

[0044] The drainage process inside the reactor is achieved by generating a siphon effect. The siphon effect is a principle that utilizes the pressure difference inside the liquid to achieve liquid flow. When drainage is required, it can be achieved by generating a siphon effect. However, when drainage through the siphon effect is not required, we need to destroy the air pressure environment inside the bell cover 130 to prevent the generation of the siphon effect.

[0045] This can be achieved by setting the opening and closing of the second air valve 145 (siphon effect destruction pipe). When it is necessary to destroy the siphon effect, open the second air valve 145 so that external air can enter the inside of the bell cover 130. Once air enters the inside of the bell cover 130, the siphon effect will be destroyed, thus achieving the purpose of stopping drainage. This design not only ensures the normal operation of the equipment but also improves the operation flexibility of the equipment.

[0046] Working principle:

[0047] The wastewater first enters the reaction chamber 110 from the outside. At this time, the outlet valve 122 is closed and the second air valve 145 is closed. As the water level in the reaction chamber 110 rises, the wastewater enters the interior of the bell 130 through the first water inlet 131 and the second water inlet 132, and then enters the outlet pipe 121 through the wastewater flow channel 133. At this time, the outlet valve 122 is closed and the wastewater cannot be discharged. When the water level in the bell 130 is higher than the water level inside the reaction chamber 110, the outlet valve 122 is opened, and the wastewater is discharged through the outlet pipe 121, taking away the air in the pipe to form a siphon effect, and the wastewater in the outlet pipe 121 will quickly drain away. And the flow rate and flow volume of the siphon effect drainage can be controlled by the opening degrees of the first air valve 144 and the outlet valve 122. When the second air valve 145 is opened, air enters the bell 130 and the siphon effect disappears. If it is necessary to generate the siphon effect again, it is necessary to close the second air valve 145 and continuously supply water to the reaction chamber 110 so that the water level inside the bell 130 reaches higher than the water level in the reaction chamber 110, and then the siphon effect water distribution can be generated again.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
