Description

Technical Field

[0001] The utility model relates to the technical field of environmental protection, in particular to a device for interchanging pulsed water inlet and gravity water inlet in a biochemical reactor. Background Art

[0002] In today's environmental protection industry, the development of wastewater treatment technology is changing with each passing day, and biochemical reaction vessels play a crucial role in this field. Due to various industrial activities and production processes, various types of wastewater are generated. These wastewaters have different types and their concentrations vary from high to low, which poses very diverse requirements for wastewater treatment equipment. In order to ensure the effective treatment of wastewater and at the same time minimize the energy consumption and cost during the treatment process, R & D personnel must adopt the most suitable water inlet mode according to different wastewater types and concentrations. Therefore, it is particularly crucial to design a biochemical reaction vessel that can flexibly switch between pulsed water inlet and gravity water inlet modes to meet different treatment requirements. The research and application of such a device can not only improve the efficiency of wastewater treatment but also provide strong support for the long-term development of China's environmental protection cause.

[0003] In the patent "A water distributor with adjustable pulse intensity and pipe layout method" (publication number CN209367918U, hereinafter referred to as the prior art 1), an adjustable pulsed water distributor is disclosed.

Among them, the regulating valve can adjust the air flow rate at the suction port of the injector, thereby adjusting the negative pressure intensity in the central siphon, and finally achieving the purpose of controlling the pulse time and intensity. A water seal device is arranged inside the water distribution tank, an exhaust pipe is arranged at the upper end of the water distribution tank, and the exhaust pipe is installed inside the water storage tank. The main water distribution pipe is arranged outside the water distribution tank, the upper end of the water distribution branch pipe is vertically connected to the main water distribution pipe, and the other end extends to the bottom of the biochemical reactor. In addition, an injector is also arranged, and the sewage inlet pipe and the water storage tank are respectively connected through the jet inlet pipe and the jet outlet pipe.

[0004] The utility model adopts an advanced regulating valve technology to precisely control the air flow rate at the suction port of the injector, and then realizes the delicate adjustment of the negative pressure intensity in the central siphon. It enables the flexible adjustment of the pulse time and intensity according to actual needs, so as to achieve more precise and effective control. However, in the prior art 1, only the control of water distribution can be carried out through adjustment, and there are many adjustment parameters, which are relatively complex and not easy to reach the desired standards and effects. Content of the Utility Model

[0005] In view of this, the embodiments of the present utility model provide a device for interchanging pulsed water inlet and gravity water inlet to a biochemical reactor, which is used to solve the problem that in the prior art, the adjustment of the water distribution effect can only be achieved through a single water distribution method, and it is not easy to achieve the desired biochemical reaction effect.

Different water distribution modes are realized through the air valve, and different types and concentrations of waste water are adopted with different water inlet modes to achieve the best treatment effect.

[0027] Embodiment 1

[0028] Please refer to Figure 1, an embodiment of the present utility model provides a device for interchanging pulsed water inlet and gravity water inlet to a biochemical reactor. In wastewater treatment, a biochemical reactor is one of the key devices. Different types and concentrations of wastewater may require different water inlet methods to achieve the best treatment effect. To adapt to these diverse treatment requirements, it is particularly important to adopt a device that can interchange between pulsed water inlet and gravity water inlet.

[0029] Please refer to Figure 1 , a biochemical reactor with the function of interchanging pulsed water inlet and gravity water inlet, whose design combines the structural characteristics of the reaction vessel 100 to achieve an efficient water treatment process. The core part of this device is the reaction vessel 100, and its internal center is a hollow structure, forming a reaction chamber 110 dedicated to biochemical reactions. In this reaction chamber 110, wastewater is introduced and participates in a series of biochemical reactions, which help to remove harmful substances in the wastewater and convert them into harmless substances, thus achieving the purpose of purifying water quality. Through this design, wastewater can be fully and evenly mixed in the reaction vessel 100, ensuring the efficiency and effect of biochemical reactions.

[0030] Please refer to Figure 1 , the top of the reaction vessel 100 is provided with an opening, and a detachable top cover 120 is provided at the opening. The top cover 120 is provided for installing and maintaining the working components inside the reaction vessel 100 to ensure the normal operation of the internal components. The reaction vessel 100 has an opening at its top, and this opening is covered by a detachable top cover 120. The design of this top cover 120 is mainly to facilitate the installation and maintenance of the working components inside the reaction vessel 100, so as to ensure the normal operation of these internal components. Through such a design, when it is necessary to maintain or replace components inside the reaction vessel 100, the top cover 120 can be easily removed without disassembling the entire container. This not only improves the maintenance efficiency but also reduces the impact of maintenance work on the container itself. The process of disassembling and installing the top cover 120 is simple and fast, significantly shortening the downtime of the reaction vessel 100 and further ensuring the continuity and stability of the production process. When wastewater needs to react, the top cover 120 is closed with the opening and sealed well to prevent the internal air flow and sewage from leaking out.

[0031] Please refer to Figure 1, a main water distribution pipe 111 is provided inside the reaction vessel 100; the reaction vessel 100 is provided with a drain port 130 at the bottom, and the main water distribution pipe 111 communicates with the reaction chamber 110 of the reaction vessel 100 through the drain port 130. The main water distribution pipe 111 is used for distributing water externally, and the wastewater is discharged into the treatment pool 300 through water distribution. This main water distribution pipe 111 plays a role in distributing water flow, ensuring that the water flow can be evenly distributed to each part inside the treatment pool 300. To achieve this goal, the reaction vessel 100 is equipped with a drain port 130 at its bottom, and this drain port 130 serves as a bridge connecting the inside of the reaction vessel 100 to the outside world. The main water distribution pipe 111 is connected to the reaction chamber 110 of the reaction vessel 100 through this drain port 130, so that the water flow can be smoothly discharged into the treatment pool 300.

[0032] Furthermore, please refer to Figure 2 , a wastewater storage device 200 is provided outside the reaction vessel 100; the main water distribution pipe 111 is connected to the bottom of the wastewater storage device 200 through a wastewater pipe 210, and wastewater is input from the wastewater storage device 200 into the reaction chamber 110 of the reaction vessel 100.

[0033] In practical applications, the function of the main water distribution pipe 111 is not only to lead the water flow out of the reaction vessel 100, but also to evenly distribute the water flow in the treatment pool 300, so that the reactants can be evenly contacted and reacted on the entire bottom surface. In addition, the main water distribution pipe 111 also needs to consider the speed and flow rate of the water flow to ensure that the reactants can be fully stirred and mixed during the reaction process, thereby improving the efficiency and uniformity of the reaction.

[0034] Please refer to Figure 1 , an inspection port 140 is also provided at the top of the reaction vessel 100, and a water inlet 170 is provided at the top and / or bottom of the reaction vessel 100. The water inlet 170 is used to add wastewater or other treatment reagents. For example, treatment reagents such as hydrogen peroxide. The treatment reagents play a role in cleaning, oxidizing or other chemical reactions on the wastewater in the reaction vessel 100. Through the drain port 130, these reagents can be accurately discharged into the treatment pool 300, thus ensuring the smooth progress of water distribution. The inspection port 140 is used to check the reaction inside the reaction chamber 110 and the working conditions of the internal components.

[0035] Please refer to Figure 1, the main water distribution pipe 111 is covered by a bell-shaped cover 112; the bell-shaped cover 112 is joined to the bottom of the reaction chamber 110 and is arranged in a sealed manner. The bell-shaped cover 112 is respectively provided with a first water inlet 116 and a second water inlet 117 on both sides near the bottom of the reaction chamber 110. The bell-shaped cover 112 covers the main water distribution pipe 111, and a waste water passage space 115 is formed in the cavity between them. Waste water enters from one end of the main water distribution pipe 111, passes through the waste water passage space 115, and then enters the main water distribution pipe 111 through the first water inlet 116 and the second water inlet 117.

[0036] Please refer to Figure 2 , the present invention also relates to a water distribution system for the reaction chamber 110. The system includes a main water distribution pipe 111, which is designed to be covered by a bell-shaped cover 112 to ensure uniform water distribution during the reaction process. The bell-shaped cover 112 is a hemispherical or similar tubular structure, which is closely joined to the bottom of the reaction chamber 110 to form a sealed space to prevent any waste water from leaking out of the reaction chamber 110 and also facilitate the formation of a siphon effect. On both sides near the bottom of the reaction chamber 110, the bell-shaped cover 112 is respectively provided with a first water inlet 116 and a second water inlet 117. The design of these two water inlets is intended to introduce water flow, so that waste water can enter the bell-shaped cover 112 from the reaction chamber 110 and stir the bottom of the treatment tank 300 when the waste water enters the treatment tank 300, stirring up the sludge at the bottom of the treatment tank 300 and continuously and fully mixing it with the sewage in the treatment tank 300. Through such a design, it can be ensured that the chemical reaction in the treatment tank 300 proceeds under the action of uniform water flow, thereby improving the reaction efficiency and uniformity.

[0037] Please refer to Figure 1 , a specific interval is provided between the main water distribution pipe 111 and the bell-shaped cover 112, and this interval is actually a waste water passage space 115. This space allows the waste water to flow out of the reaction chamber 110 and enter the waste water passage space 115 through the first water inlet 116 and the second water inlet 117. During this process, the waste water can flow freely in this space, so as to carry out preliminary filtration and treatment in the reaction chamber 110 before entering the treatment tank 300. The bell-shaped cover 112 completely covers the main water distribution pipe 111 inside, so that the cavity between the main water distribution pipe 111 and the bell-shaped cover 112 forms a waste water passage space 115. In this space, the waste water enters from one end of the main water distribution pipe 111, passes through this waste water passage space 115, and finally is discharged into the reaction tank 300 through the drain port 130.

[0038] Please refer to Figure 1, a connecting pipe 113 is also provided at the top of the bell jar 112, and both ends of the connecting pipe 113 communicate the inside of the bell jar 112 with the outside of the reaction vessel 100. Further, the connecting pipe 113 is a siphon-breaking pipe. The pulse water distribution of the biochemical system is mainly based on the pulse signal and the siphon principle. It uses the rapidly flowing water in the main water distribution pipe 111 to carry away the air in the main water distribution pipe 111, so that a certain degree of vacuum is formed in the main water distribution pipe 111. Under the action of the atmospheric pressure inside and outside the main water distribution pipe 111, the water in the container enters the main water distribution pipe 111 and then is discharged into the treatment tank 300. Due to the very fast water flow velocity during the siphon effect, the water distribution can be completed in a short time, achieving the pulse effect, stirring up the sludge at the bottom of the treatment tank 300, and continuously and fully mixing it with the sewage in the tank. The pulse water distributor can distribute water quickly and evenly, improving the treatment efficiency of the biochemical reactor. At the same time, due to its simple structure and no other power required except for the inlet water lift, the energy consumption is relatively low.

[0039] The siphon effect is a natural phenomenon, which refers to the transfer of a liquid from one container to another through a pipe and can maintain the flow by itself. Even when transferring the liquid from a higher place to a lower place, the final part of the liquid flow is upward. To produce this effect, it is necessary to ensure that a sufficient degree of vacuum is formed and maintained in the main water distribution pipe 111. And it is necessary to ensure that the liquid level of the wastewater in the reaction chamber 110 is higher than the height of the bell jar to enable the formation of the siphon effect. However, once there is a connecting pipe 113, that is, a siphon-breaking pipe, this situation is difficult to achieve. Because this pipe will connect the main water distribution pipe 111 with the external environment, and once it is opened, the external air will flow in and destroy the vacuum environment in the main water distribution pipe 111. The loss of the degree of vacuum means the end of the siphon effect, because this effect relies on the vacuum area above the liquid in the pipe to push the liquid to flow. Therefore, if you want to maintain the siphon effect, it is necessary to ensure that the connecting pipe 113 always remains closed to prevent the intrusion of external air, so as to keep the degree of vacuum in the main water distribution pipe 111 from being damaged.

[0040] Please refer to Figure 1, a connecting pipe 113 is arranged in the reaction vessel 100, and its opening and closing are realized through a gas valve 114. This gas valve 114 is not just a simple mechanical structure; it is the key to controlling the connection and disconnection of the main water distribution pipe 111. When the gas valve 114 is opened, it allows external air to communicate with the main water distribution pipe 111 through the connecting pipe 113, causing the siphon effect to fail instantly. The siphon effect, a common phenomenon in nature, relies on the pressure difference to drive the liquid flow, and the opening of the gas valve 114 breaks this balance, making the liquid unable to flow naturally through the pipe. However, when the gas valve 114 closes slowly, the circulation between the main water distribution pipe 111 and the external air will be closed again. At this time, the siphon effect is re-formed. The height difference between the liquid levels becomes the driving force again, allowing the liquid to flow smoothly in the pipe.

[0041] When the gas valve 114 is closed or opened, the siphon effect is lost, and only the height difference between the reaction vessel 100 and the wastewater level in the bell jar can be relied on to drain the wastewater by gravity. The drainage effect during gravity water inlet is slower.

[0042] The biochemical reactor is provided with a siphon-breaking valve. When the influent concentration of the biochemical system is high, the biodegradability is good, and the amount of biogas generated by its own reaction is large, the agitation formed by the biogas in the treatment tank 300 can be utilized. At this time, the siphon-breaking valve is opened, and the gravity water distribution method is adopted to avoid excessive water volume impact on the sludge in the tank, resulting in the dispersion of the sludge flocs and affecting the treatment effect; when the influent concentration of the biochemical system is low, the biodegradability is poor, and not much biogas and other gases can be generated. At this time, the siphon-breaking valve is closed, and the treatment tank 300 is stirred through the pulse effect to make the microorganisms fully contact with the sewage and improve the treatment efficiency of the biochemical reactor.

[0043] Please refer to Figure 1 , during the operation of the treatment system, the closing and opening of the gas valve 114 are a key step, which directly affects the generation of the siphon effect. Once the siphon effect is lost, the system will rely on the height difference between the wastewater storage tank and the reaction vessel 100, and utilize the power of gravity to introduce the wastewater. The effective operation of this gravity water distribution depends on the undulation of the terrain or the water level difference inside and outside the reaction vessel 100 to achieve natural flow and water inlet.

[0044] In the design of the biochemical reactor, a gas valve 114 (siphon-breaking valve) is provided, and this design cleverly responds to different influent conditions of the biochemical system. When the influent concentration is high, it means that the biodegradability is good, and the amount of biogas generated during the biochemical reaction is also relatively large. At this time, the agitation effect generated by the biogas in the tank can be utilized. By opening the siphon-breaking valve and adopting the gravity water distribution method, it can effectively avoid the dispersion of the sludge flocs in the tank caused by excessive water flow impact, thus ensuring that the treatment effect is not affected.

[0045] On the contrary, when the influent concentration of the biochemical system is low, indicating poor biodegradability and no generation of a large amount of gases such as biogas, the siphon-breaking valve will be closed. In this case, the system will improve the contact degree between microorganisms and sewage through pulse stirring to ensure full mixing of the two, thereby enhancing the treatment efficiency of the biochemical reactor. Such a design fully reflects the careful consideration of different working conditions in the biochemical treatment process and the pursuit of system optimization and efficiency improvement.

[0046] The main water distribution pipe 111 plays a crucial role in the reaction vessel 100. It is not only responsible for introducing water flow into the treatment tank 300 but also for evenly distributing the water flow over the entire bottom surface of the treatment tank 300, thereby ensuring that the reactants can be evenly contacted and reacted over the entire bottom surface, improving the efficiency and uniformity of the reaction.

[0047] Please refer to Figure 3 , one end of the main water distribution pipe 111 extends towards the direction close to the opening, and the other end extends outside the reaction chamber 110. Such a design enables the main water distribution pipe 111 to have sufficient length to generate a siphon effect and introduce wastewater. The siphon effect is a fluid phenomenon. When one end of a tube is immersed in a liquid and the other end is kept with the opening facing downwards, the liquid will form a region with lower air pressure inside the tube, causing the liquid to rise along the wastewater passage space 115. In the main water distribution pipe 111, when the wastewater flows through the tube, due to the extension of one end of the tube, a siphon phenomenon can be formed inside the tube, thereby introducing the wastewater into the treatment tank 300. In addition, the other end of the main water distribution pipe 111 extends outside the reaction chamber 110, facilitating the treatment and discharge of wastewater. This design not only improves the wastewater treatment efficiency but also reduces the environmental impact of wastewater. The structural design of the main water distribution pipe 111 not only realizes the introduction and treatment of wastewater but also utilizes the siphon effect, improving the operating efficiency of the entire system.

[0048] The joint part between the main water distribution pipe 111 and the bottom of the reaction chamber 110 is designed as a sealed structure. This design ensures that no wastewater leaks, and at the same time, it guarantees that the internal chemical reaction can be effectively repeated in a closed environment. Such a sealed setting not only improves the safety performance of the entire system but also ensures the continuity and stability of the reaction, avoiding any possible pollution problems caused by leakage, and further enhancing the operation efficiency and reliability. Furthermore, it can also ensure the sealing degree inside the wastewater passage space 115, enabling a smooth formation of the siphon effect for water distribution.

[0049] Please refer to Figure 1, on one side of the drain port 130, a drain opening 150 is provided. This drain opening 150 does not exist in isolation but is connected to a dedicated drain pipe 151. This drain pipe 151 is in close connection with the reaction chamber 110, enabling the drain opening 150 to play its key role during operation, that is, through the drain opening 150, the waste gas accumulated inside the reaction chamber 110 can be completely and comprehensively discharged, ensuring the cleanliness inside the reaction chamber 110 and providing a clean and safe environment for subsequent work processes. The drain opening 150 is used for exhausting gas after the internal treatment is completed.

[0050] In the reaction vessel 100 described above, a dedicated exhaust port 160 is designed at its top. This exhaust port 160 is connected to the outside through an openable and closable exhaust pipe 161. The function of this exhaust pipe 161 is to ensure that all the waste gas generated during the reaction process can be effectively discharged, thereby ensuring the pressure balance inside the reaction vessel 100 and preventing unsafe factors caused by abnormal pressure. At the same time, this design also fully considers the environmental protection requirements, and the waste gas discharged through the exhaust pipe 161 will be treated to reduce the impact on the environment. When wastewater is introduced, the wastewater inside the reaction chamber 110 will expel the air, and at this time, the air is also discharged through the exhaust port 160. The exhaust port 160 is used for discharging the waste gas inside during the reaction and can also be used to control the air pressure inside the reaction chamber 110 to achieve the control of the wastewater discharge rate.

[0051] The main water distribution pipe 111 is located at one end inside the reaction chamber 110, and the port here is designed as an open structure. At the same time, at the water inlet end of the main water distribution pipe 111 outside the reaction chamber 110, a water outlet valve is equipped, and this valve can achieve the on-off control of the water flow.

[0052] Please refer to Figure 3 , when the air valve 114 performs a closing operation, it can seal the connecting pipe 113, thereby forming a complete closed system among the reaction chamber 110, the first water inlet 116, the second water inlet 117, and the main water distribution pipe 111, and then constructing a path for pulsed water distribution. During this process, the distribution of water flow completely depends on the pulsed power generated by the siphon effect, thereby generating a corresponding pulsed effect inside the reaction chamber 110 and forming a siphon effect for water distribution operations.

[0053] In contrast, when the air valve 114 performs an opening operation, it allows the connecting pipe 113 to be unobstructed. At this time, a connected system is formed among the reaction chamber 110, the first water inlet 116, the second water inlet 117, and the main water distribution pipe 111, thereby forming a gravity water distribution path. In this mode, the distribution of water flow mainly relies on the action of gravity, enabling the water flow to flow naturally, and thus generating corresponding gravity water distribution inside the reaction chamber 110. By controlling the opening and closing of the air valve 114, the switching between pulsed water distribution and gravity water distribution can be achieved, thereby providing different water flow distribution methods inside the reaction chamber 110 to meet different treatment or industrial requirements. This design cleverly utilizes physical principles to achieve flexible control of the water distribution method, greatly improving the practicability and flexibility of the reaction chamber 110. Further, there will still be residual wastewater in the reaction chamber after drainage, which can be discharged through the water inlet 170 or the vent 150.

[0054] Working principle: The wastewater first enters the reaction chamber from the outside. At this time, the drain port 130 is open. When the wastewater inside the reaction chamber 110 gradually increases, the liquid level gradually rises, and when the water level inside the bell jar 112 is higher than the water level inside the reaction chamber 110, the wastewater will continuously enter the wastewater passage space inside the bell jar 112 through the first water inlet 116 and the second water inlet 117, and then enter the main water distribution pipe 111. At this time, the water flow velocity is relatively fast, exhausting the air in the main water distribution pipe 111 to form a siphon effect, and the wastewater is introduced into the treatment tank 300 by the main water distribution pipe 111. When gravity water distribution is required, the air valve 114 is opened, air enters the inside of the bell jar 112, destroying the siphon effect, and water distribution is carried out relying on the gravity generated by the height difference between the wastewater liquid level inside the reaction chamber 110 and the liquid level inside the bell jar 112. By opening and closing the air valve 114, the switching between gravity water distribution and siphon water distribution is achieved to obtain different water distribution effects. It should be noted here that the process of pulsed water inlet is as follows: Water is added to the reaction chamber 110 until the water level inside the bell jar 112 is higher than the water level inside the reaction chamber 110. After the air in the main water distribution pipe 111 is exhausted to form a siphon effect, the addition of water to the reaction chamber 110 is stopped; at this time, the wastewater flows from the main water distribution pipe into the treatment tank 300, forming a "pulse" drainage effect. Thereafter, the above process can be repeated as needed to generate several "pulse" drainages, that is, the pulsed water inlet in this embodiment produces the effect of "pulse" drainage. After several pulsed drainages, the bottom of the treatment tank 300 can be stirred.
