Abstract

The application discloses a catalytic degradation device for organic pollutants and belongs to the field of organic pollutant treatment. The device comprises a treatment tank and a tank cover installed on the upper portion of the treatment tank. A plurality of partition plates are linearly connected in the tank cover. When the tank cover moves downward, the partition plates contact the bottom wall of the treatment tank, thereby dividing the treatment tank into a plurality of spaces. When the tank cover moves downward, the partition plates contact the bottom wall of the treatment tank, thereby dividing the treatment tank into a plurality of independent reaction chambers. Each reaction chamber can independently perform a catalytic degradation reaction, thereby improving the reaction efficiency and degradation effect. Meanwhile, the linearly connected partition plates can ensure the material transmission and mixing between the reaction chambers, thereby realizing more uniform reaction conditions. When the treatment tank is filled with organic pollutant wastewater to be treated, the tank cover is in an upward moving state. At this time, the partition plates do not contact the bottom wall of the treatment tank, thereby reducing the resistance of the organic pollutant wastewater filling.

Description

Technical Field

[0001] This invention relates to the field of organic pollutant treatment technology, specifically to a catalytic degradation device for organic pollutants. Background Technology

[0002] In catalytic degradation technology, the design of the treatment tank is crucial for improving reaction efficiency and degradation effect. Traditional treatment tanks are usually designed as a single unit, which cannot be divided into multiple independent reaction chambers. As a result, the reaction conditions are uneven and the reaction efficiency is low. At the same time, the single unit design also restricts the transfer and mixing of substances, which further affects the degradation effect. To address these issues, a new type of treatment tank design is needed to improve reaction efficiency and degradation effect.

[0003] In addition, when adding the organic pollutant wastewater to the treatment tank, it is necessary to overcome the injection resistance. Traditional injection methods may encounter problems such as high injection resistance and uneven injection, which affect the treatment effect. Therefore, how to reduce the injection resistance of organic pollutant wastewater and improve the injection uniformity is also a problem that needs to be solved in the current catalytic degradation technology. Summary of the Invention

[0004] The purpose of this invention is to provide a catalytic degradation device for organic pollutants, which solves the problems of uneven reaction conditions and low reaction efficiency in existing devices, and the potential for high injection resistance and uneven injection in traditional injection methods.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a catalytic degradation device for organic pollutants, comprising a treatment tank and a tank cover installed on the upper part of the treatment tank, wherein multiple partitions are linearly connected inside the tank cover, and when the tank cover moves down, it causes the partitions to contact the bottom wall of the treatment tank, thereby dividing the treatment tank into multiple spaces.

[0006] Preferably, a sliding rod is fixedly connected to the top of the partition, and a hole is opened on the groove cover to cooperate with the sliding rod. A spring is sleeved on the sliding rod, and the two ends of the spring are fixedly connected to the groove cover and the partition, respectively.

[0007] Preferably, a heating tube is fixedly connected to the side of the partition, and a heat source medium flows inside the heating tube.

[0008] Preferably, a plurality of vertically arranged disturbance plates are slidably connected to the partition plate on the other side of the heating tube. A piston rod is fixedly connected to the upper surface of the disturbance plate, and a piston cylinder is fixedly connected to the side of the partition plate. The piston rod is slidably connected inside the piston cylinder, and a filling pipe is fixedly connected to the piston cylinder. The filling pipe is connected to an external liquid catalyst. When the catalyst is injected into the piston cylinder through the filling pipe, the piston rod slides out of the piston cylinder and drives the disturbance plates to slide relative to the partition plate.

[0009] Preferably, the piston rod and the disturbance plate have a common drainage hole, an insert rod is fixedly connected inside the piston cylinder and inserted into the drainage hole, and a tension spring is placed inside the piston cylinder, with both ends of the tension spring fixedly connected to the piston cylinder and the piston rod, respectively.

[0010] Preferably, an inlet pipe is fixedly connected to the side of the treatment tank, and an exhaust hole is provided on the tank cover. When liquid is added into the treatment tank through the inlet pipe, the exhaust hole is located at the upper part of the side wall of the treatment tank.

[0011] Preferably, a rack is fixedly connected to the side of the tank cover, a drain pipe is fixedly connected to the side wall of the treatment tank, an L-shaped pipe is rotatably connected to the end of the drain pipe, a gear is fixedly connected to the L-shaped pipe, the rack meshes with the gear, a first semi-circular hole is opened in the drain pipe, a second semi-circular hole is opened in the L-shaped pipe, and when the L-shaped pipe is in a vertical state, the first semi-circular hole is not connected to the second semi-circular hole.

[0012] Preferably, a rectangular frame is fixedly connected to the side wall of the treatment tank, and the rectangular frame is located above the drain pipe and the inlet pipe.

[0013] Preferably, four hydraulic rods are fixedly connected to the four corners of the processing tank, and the output ends of the four hydraulic rods are respectively fixedly connected to the four corners of the tank cover.

[0014] Preferably, a thin rod is fixedly connected to the processing tank, and a thick rod is coaxially fixedly connected to the top of the thin rod. The tank cover has a hole that mates with the thick rod. When the tank cover is moved down so that the L-shaped tube rotates 90 degrees, the thin rod moves into the hole of the tank cover.

[0015] An exhaust pipe is fixedly connected to the trough cover, and a one-way valve is installed on the exhaust pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When the tank cover moves down, the partition contacts the bottom wall of the treatment tank, dividing the treatment tank into multiple independent reaction chambers. Each reaction chamber can independently carry out catalytic degradation reaction, improving reaction efficiency and degradation effect. At the same time, the linearly connected partition design can ensure the material transfer and mixing between each reaction chamber, thereby achieving more uniform reaction conditions. When adding the organic pollutant wastewater to be treated into the treatment tank, the tank cover is in the upward state. At this time, the partition does not contact the bottom wall of the treatment tank, thereby reducing the resistance of adding organic pollutant wastewater.

[0018] 2. In this invention, a heating pipe is fixedly connected to the side of the partition. A heat source medium flows inside the heating pipe. This medium can be hot water, hot oil, or other fluids with good thermal conductivity. When the heat source medium flows inside the heating pipe, it transfers heat to the partition and the organic pollutants in the treatment tank that it contacts. This heat transfer process helps to accelerate the catalytic degradation reaction of organic pollutants. In addition, since the heating pipe is fixed to the partition, the heat can be evenly distributed in each space of the treatment tank, thereby ensuring the uniformity of the catalytic degradation reaction, which helps to improve the degradation efficiency and reduce energy waste.

[0019] 3. In this invention, the disturbance plate is vertically arranged and can slide on the partition plate. During the catalytic degradation process, it disturbs the organic pollutants and catalyst in the treatment tank, thereby enhancing their mixing and contact. Through disturbance, the interfacial barrier between pollutants and catalyst can be broken, increasing the reaction surface area, thereby improving the rate and efficiency of the catalytic degradation reaction. The piston rod is fixedly connected to the disturbance plate and can slide inside the piston cylinder. When liquid catalyst is injected into the piston cylinder through the injection pipe, the piston rod slides out of the piston cylinder due to the pressure of the liquid. The injection pressure of the liquid catalyst is used to drive the sliding of the disturbance plate, realizing an automated mixing and disturbance process. The injection pipe is connected to an external liquid catalyst source, allowing the catalyst to be injected into the piston cylinder periodically or continuously. This ensures that the catalytic degradation reaction can continue, and the amount of catalyst added can be adjusted as needed. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example

[0032] Reference Figure 1 - Figure 9 The present invention provides a technical solution: a catalytic degradation device for organic pollutants includes a treatment tank 1 and a tank cover 11 installed on the upper part of the treatment tank 1. Multiple partitions 2 are linearly connected inside the tank cover 11. When the tank cover 11 moves down, it causes the partitions 2 to contact the bottom wall of the treatment tank 1, thereby dividing the treatment tank 1 into multiple spaces.

[0033] When the tank cover 11 moves down, the partition 2 contacts the bottom wall of the treatment tank 1, dividing the treatment tank 1 into multiple independent reaction chambers. Each reaction chamber can independently carry out catalytic degradation reaction, improving reaction efficiency and degradation effect. At the same time, the linearly connected partition 2 design can ensure the material transfer and mixing between each reaction chamber, thereby achieving more uniform reaction conditions. When adding the organic pollutant wastewater to be treated into the treatment tank 1, the tank cover 11 is in the upward state. At this time, the partition 2 does not contact the bottom wall of the treatment tank 1, thereby reducing the resistance to adding organic pollutant wastewater.

[0034] A sliding rod 21 is fixedly connected to the top of the partition 2. The groove cover 11 has a hole that mates with the sliding rod 21. A spring 23 is sleeved on the sliding rod 21. The two ends of the spring 23 are fixedly connected to the groove cover 11 and the partition 2, respectively.

[0035] The spring 23 is configured to provide support for the descending tank cover 11. When the partition 2 contacts the bottom wall of the processing tank 1, the spring 23 is under compression. At the same time, the spring 23 provides an elastic buffer mechanism, which allows the partition 2 to automatically adjust its position during movement to ensure stable contact with the bottom wall of the processing tank 1. The two ends of the spring 23 are fixedly connected to the tank cover 11 and the partition 2, respectively. The spring 23 not only provides elastic support for the partition 2, but also tightly connects it to the tank cover 11, which helps to maintain the overall stability and structural integrity of the device.

[0036] A heating tube 22 is fixedly connected to the side of the partition 2, and a heat source medium flows inside the heating tube 22.

[0037] A heating pipe 22 is fixedly connected to the side of the partition 2. A heat source medium flows inside the heating pipe 22. This medium can be hot water, hot oil, or other fluids with good thermal conductivity. When the heat source medium flows inside the heating pipe 22, it transfers heat to the partition 2 and the organic pollutants in the treatment tank 1 that are in contact with it. This heat transfer process helps to accelerate the catalytic degradation reaction of organic pollutants. In addition, since the heating pipe 22 is fixed on the partition 2, the heat can be evenly distributed in each space of the treatment tank 1, thereby ensuring the uniformity of the catalytic degradation reaction, which helps to improve the degradation efficiency and reduce energy waste.

[0038] Multiple vertically arranged disturbance plates 24 are slidably connected to the partition plate 2 on the other side of the heating tube 22. A piston rod 28 is fixedly connected to the upper surface of the disturbance plate 24. A piston cylinder 25 is fixedly connected to the side of the partition plate 2. The piston rod 28 is slidably connected inside the piston cylinder 25. A filling pipe 251 is fixedly connected to the piston cylinder 25. The filling pipe 251 is connected to an external liquid catalyst. When the catalyst is injected into the piston cylinder 25 through the filling pipe 251, the piston rod 28 slides out of the piston cylinder 25 and drives the disturbance plate 24 to slide relative to the partition plate 2.

[0039] The disturbance plate 24 is vertically arranged and can slide on the partition plate 2. During the catalytic degradation process, it disturbs the organic pollutants and catalyst in the treatment tank 1, thereby enhancing their mixing and contact. Through disturbance, the interfacial barrier between pollutants and catalyst can be broken, increasing the reaction surface area, thereby improving the rate and efficiency of the catalytic degradation reaction. The piston rod 28 is fixedly connected to the disturbance plate 24 and can slide inside the piston cylinder 25. When liquid catalyst is injected into the piston cylinder 25 through the injection pipe 251, the piston rod 28 slides out of the piston cylinder 25 due to the pressure of the liquid. The injection pressure of the liquid catalyst is used to drive the sliding of the disturbance plate 24, realizing an automated mixing and disturbance process. The injection pipe 251 is connected to an external liquid catalyst source, allowing the catalyst to be injected into the piston cylinder 25 periodically or continuously. This ensures that the catalytic degradation reaction can continue and the amount of catalyst added can be adjusted as needed.

[0040] The piston rod 28 and the disturbance plate 24 are both provided with a drain hole 29. A plug rod 27 is fixedly connected inside the piston cylinder 25 and is inserted into the drain hole 29. A tension spring 26 is placed inside the piston cylinder 25, and the two ends of the tension spring 26 are fixedly connected to the piston cylinder 25 and the piston rod 28 respectively.

[0041] When the catalyst is added into the piston cylinder 25 through the injection pipe 251, the pressure inside the piston cylinder 25 causes the piston rod 28 to move downward. As the piston rod 28 moves downward, the insertion rod 27 can be pulled out from the drain hole 29, so that the catalyst can be discharged through the drain hole 29. After the catalyst is discharged from the drain hole 29, the pressure inside the piston cylinder 25 decreases. At this time, the tension spring 26 pulls on the piston rod 28, causing the piston rod 28 to move upward. Thus, when the disturbance plate 24 moves up and down, the catalyst is sprayed out synchronously, ensuring the mixing effect of the catalyst and the organic pollutant wastewater and improving the catalytic degradation effect.

[0042] The side of the treatment tank 1 is fixedly connected to the liquid inlet pipe 18, and the tank cover 11 is provided with an exhaust hole 32. When liquid is added into the treatment tank 1 through the liquid inlet pipe 18, the exhaust hole 32 is located at the upper part of the side wall of the treatment tank 1.

[0043] The vent 32 is located on the upper part of the side wall of the treatment tank 1, which helps to release gas or foam that may accumulate in the treatment tank 1 during the filling process. When liquid is added to the treatment tank 1 through the liquid inlet pipe 18, the gas or foam rises to the upper part of the treatment tank 1 due to the force of the liquid. The vent 32 allows these gases or foams to be discharged from the hole, thereby preventing the gas or foam from accumulating in the treatment tank 1 and ensuring the smooth progress of the filling process. In addition, the vent 32 also helps to reduce the pressure that may be generated during the filling process and prevent overpressure caused by the accumulation of gas or foam.

[0044] A rack 12 is fixedly connected to the side of the tank cover 11, and a drain pipe 13 is fixedly connected to the side wall of the treatment tank 1. An L-shaped pipe 14 is rotatably connected to the end of the drain pipe 13. A gear 15 is fixedly connected to the L-shaped pipe 14. The rack 12 meshes with the gear 15. A first semi-circular hole 131 is opened in the drain pipe 13, and a second semi-circular hole 151 is opened in the L-shaped pipe 14. When the L-shaped pipe 14 is in a vertical state, the first semi-circular hole 131 is not connected to the second semi-circular hole 151.

[0045] A rack 12 is fixed to the side of the tank cover 11, and a gear 15 on the L-shaped tube 14 meshes with the rack 12 on the side wall of the treatment tank 1. When the tank cover 11 moves, the rack 12 drives the gear 15 to rotate. The rotation of the gear 15 causes the L-shaped tube 14 to rotate on the side wall of the treatment tank 1. Since the L-shaped tube 14 is rotatably connected to the drain pipe 13, the L-shaped tube 14 can rotate freely relative to the drain pipe 13. When the L-shaped tube 14 is in a vertical state, the first semicircular hole 131 is not connected to the second semicircular hole 151. This means that the drain pipe 13 is closed and the liquid in the treatment tank 1 cannot flow out. When it is necessary to drain the liquid, the rack 12 drives the gear 15 to rotate by moving the tank cover 11, thereby causing the L-shaped tube 14 to rotate from a vertical state to a horizontal state. During this process, the first semicircular hole 131 and the second semicircular hole 151 will gradually align and eventually connect, allowing the liquid in the treatment tank 1 to flow out.

[0046] A rectangular frame 16 is fixedly connected to the side wall of the treatment tank 1. The rectangular frame 16 is located above the drain pipe 13 and the inlet pipe 18.

[0047] The rectangular frame 16 located on the upper part of the drain pipe 13 and the inlet pipe 18 can prevent the drain pipe 13 and the inlet pipe 18 from being impacted when the tank cover 11 is lowered.

[0048] Four hydraulic rods 17 are fixedly connected to the four corners of the treatment tank 1, and the output ends of the four hydraulic rods 17 are respectively fixedly connected to the four corners of the tank cover 11.

[0049] Hydraulic rods 17 are typically driven by high-pressure hydraulic oil, providing significant support and adjustability. When the end of hydraulic rod 17 is fixedly connected to the tank cover 11, the opening height of the tank cover 11 can be changed by adjusting the oil pressure inside the hydraulic rod 17. Four hydraulic rods 17 are fixed at the four corners of the processing tank 1, providing stable and uniform support for the tank cover 11, ensuring that the tank cover 11 remains stable under various operating conditions. By adjusting the oil pressure inside the hydraulic rods 17, the position of the tank cover 11 can be flexibly adjusted. After filling the processing tank 1, the hydraulic rods 17 are shortened, causing the tank cover 11 to move downwards. At this time, the vent 32 is blocked by the outer wall of the processing tank 1, thus sealing the processing tank 1 and preventing odor leakage. During this process, the rack 12 moves downwards with the tank cover 11. When the rack 12 is about to contact the gear 15, the hydraulic rod 17 stops retracting.

[0050] A thin rod 31 is fixedly connected to the processing tank 1. A thick rod 3 is coaxially fixedly connected to the top of the thin rod 31. A hole is opened on the tank cover 11 to cooperate with the thick rod 3. When the tank cover 11 is moved down so that the L-shaped tube 14 rotates 90 degrees, the thin rod 31 moves into the hole of the tank cover 11. An exhaust pipe 4 is fixedly connected to the tank cover 11. A one-way valve 41 is installed on the exhaust pipe 4.

[0051] During the swinging of the L-shaped tube 14, the tank cover 11 moves downward relative to the treatment tank 1. At this time, the thick rod 3 on the treatment tank 1 slides relative to the tank cover 11. Before the L-shaped tube 14 swings to a horizontal state, the thick rod 3 does not disengage from the hole on the tank cover 11. As it continues to move downward, the thin rod 31 moves into the hole on the tank cover 11. At this time, external air can enter the treatment tank 1 through the hole on the tank cover 11, so that the organic wastewater in the treatment tank 1 can be discharged from the L-shaped tube 14. During this process, the inside of the treatment tank 1 is still sealed. During the downward movement of the tank cover 11, the air in the treatment tank 1 is discharged through the exhaust pipe 4. The one-way valve 41 on the exhaust pipe 4 makes the air flow in one direction. The exhaust pipe 4 is connected to an external storage device to store the gas after the reaction, reducing the pollution to the external environment.

[0052] Working principle: When the tank cover 11 moves down, the partition 2 contacts the bottom wall of the treatment tank 1, dividing the treatment tank 1 into multiple independent reaction chambers. Each reaction chamber can independently carry out catalytic degradation reaction, improving reaction efficiency and degradation effect. At the same time, the linearly connected partition 2 design can ensure the material transfer and mixing between each reaction chamber, thereby achieving more uniform reaction conditions. When adding the organic pollutant wastewater to be treated into the treatment tank 1, the tank cover 11 is in the upward state. At this time, the partition 2 does not contact the bottom wall of the treatment tank 1, thereby reducing the resistance of adding organic pollutant wastewater.

[0053] The spring 23 is configured to provide support for the descending tank cover 11. When the partition 2 contacts the bottom wall of the processing tank 1, the spring 23 is under compression. At the same time, the spring 23 provides an elastic buffer mechanism, which allows the partition 2 to automatically adjust its position during movement to ensure stable contact with the bottom wall of the processing tank 1. The two ends of the spring 23 are fixedly connected to the tank cover 11 and the partition 2, respectively. The spring 23 not only provides elastic support for the partition 2, but also tightly connects it to the tank cover 11, which helps to maintain the overall stability and structural integrity of the device.

[0054] A heating pipe 22 is fixedly connected to the side of the partition 2. A heat source medium flows inside the heating pipe 22. This medium can be hot water, hot oil, or other fluids with good thermal conductivity. When the heat source medium flows inside the heating pipe 22, it transfers heat to the partition 2 and the organic pollutants in the treatment tank 1 that are in contact with it. This heat transfer process helps to accelerate the catalytic degradation reaction of organic pollutants. In addition, since the heating pipe 22 is fixed on the partition 2, the heat can be evenly distributed in each space of the treatment tank 1, thereby ensuring the uniformity of the catalytic degradation reaction, which helps to improve the degradation efficiency and reduce energy waste.

[0055] The disturbance plate 24 is vertically arranged and can slide on the partition plate 2. During the catalytic degradation process, it disturbs the organic pollutants and catalyst in the treatment tank 1, thereby enhancing their mixing and contact. Through disturbance, the interfacial barrier between pollutants and catalyst can be broken, increasing the reaction surface area, thereby improving the rate and efficiency of the catalytic degradation reaction. The piston rod 28 is fixedly connected to the disturbance plate 24 and can slide inside the piston cylinder 25. When liquid catalyst is injected into the piston cylinder 25 through the injection pipe 251, the piston rod 28 slides out of the piston cylinder 25 due to the pressure of the liquid. The injection pressure of the liquid catalyst is used to drive the sliding of the disturbance plate 24, realizing an automated mixing and disturbance process. The injection pipe 251 is connected to an external liquid catalyst source, allowing the catalyst to be injected into the piston cylinder 25 periodically or continuously. This ensures that the catalytic degradation reaction can continue and the amount of catalyst added can be adjusted as needed.

[0056] When the catalyst is added into the piston cylinder 25 through the injection pipe 251, the pressure inside the piston cylinder 25 causes the piston rod 28 to move downward. As the piston rod 28 moves downward, the insertion rod 27 can be pulled out from the drain hole 29, so that the catalyst can be discharged through the drain hole 29. After the enzyme catalyst is discharged from the drain hole 29, the pressure inside the piston cylinder 25 decreases. At this time, the tension spring 26 pulls the piston rod 28, causing the piston rod 28 to move upward. Thus, when the disturbance plate 24 moves up and down, the catalyst is sprayed out synchronously, ensuring the mixing effect of the catalyst and the organic pollutant wastewater and improving the catalytic degradation effect.

[0057] The vent 32 is located on the upper part of the side wall of the treatment tank 1, which helps to release gas or foam that may accumulate in the treatment tank 1 during the filling process. When liquid is added to the treatment tank 1 through the liquid inlet pipe 18, the gas or foam rises to the upper part of the treatment tank 1 due to the force of the liquid. The vent 32 allows these gases or foams to be discharged from the hole, thereby preventing the gas or foam from accumulating in the treatment tank 1 and ensuring the smooth progress of the filling process. In addition, the vent 32 also helps to reduce the pressure that may be generated during the filling process and prevent overpressure caused by the accumulation of gas or foam.

[0058] A rack 12 is fixed to the side of the tank cover 11, and a gear 15 on the L-shaped tube 14 meshes with the rack 12 on the side wall of the treatment tank 1. When the tank cover 11 moves, the rack 12 drives the gear 15 to rotate. The rotation of the gear 15 causes the L-shaped tube 14 to rotate on the side wall of the treatment tank 1. Since the L-shaped tube 14 is rotatably connected to the drain pipe 13, the L-shaped tube 14 can rotate freely relative to the drain pipe 13. When the L-shaped tube 14 is in a vertical state, the first semicircular hole 131 is not connected to the second semicircular hole 151. This means that the drain pipe 13 is closed and the liquid in the treatment tank 1 cannot flow out. When it is necessary to drain the liquid, the rack 12 drives the gear 15 to rotate by moving the tank cover 11, thereby causing the L-shaped tube 14 to rotate from a vertical state to a horizontal state. During this process, the first semicircular hole 131 and the second semicircular hole 151 will gradually align and eventually connect, allowing the liquid in the treatment tank 1 to flow out.

[0059] The rectangular frame 16 located on the upper part of the drain pipe 13 and the inlet pipe 18 can prevent the drain pipe 13 and the inlet pipe 18 from being impacted when the tank cover 11 is lowered.

[0060] The hydraulic rod 17 is driven by high-pressure hydraulic oil and has a large supporting force and adjustability. When the end of the hydraulic rod 17 is fixedly connected to the tank cover 11, the opening height of the tank cover 11 can be changed by adjusting the oil pressure inside the hydraulic rod 17. The four hydraulic rods 17 are fixed at the four corners of the processing tank 1, providing stable and uniform supporting force for the tank cover 11, ensuring that the tank cover 11 remains stable under various operating conditions. By adjusting the oil pressure inside the hydraulic rod 17, the position of the tank cover 11 can be flexibly adjusted. After filling the processing tank 1, the hydraulic rod 17 is shortened, thereby moving the tank cover 11 downward. At this time, the vent 32 is blocked by the outer wall of the processing tank 1, so that the processing tank 1 is in a sealed state to prevent odor leakage. During this process, the rack 12 moves downward with the tank cover 11. When the rack 12 is about to contact the gear 15, the hydraulic rod 17 stops retracting.

[0061] During the swinging of the L-shaped tube 14, the tank cover 11 moves downward relative to the treatment tank 1. At this time, the thick rod 3 on the treatment tank 1 slides relative to the tank cover 11. Before the L-shaped tube 14 swings to a horizontal state, the thick rod 3 does not disengage from the hole on the tank cover 11. As it continues to move downward, the thin rod 31 moves into the hole on the tank cover 11. At this time, external air can enter the treatment tank 1 through the hole on the tank cover 11, so that the organic wastewater in the treatment tank 1 can be discharged from the L-shaped tube 14. During this process, the inside of the treatment tank 1 is still sealed. During the downward movement of the tank cover 11, the air in the treatment tank 1 is discharged through the exhaust pipe 4. The one-way valve 41 on the exhaust pipe 4 makes the air flow in one direction. The exhaust pipe 4 is connected to an external storage device to store the gas after the reaction, reducing the pollution to the external environment.

[0062] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
