Description

Technical Field

[0001] This utility model relates to the technical field of landfill leachate treatment equipment, and specifically discloses a landfill leachate treatment equipment with deodorization function. Background Technology

[0002] With the acceleration of urbanization, leachate from landfills and incinerators has become one of the challenges in environmental pollution control due to its high concentration of organic matter, ammonia nitrogen, hydrogen sulfide, and volatile odorous substances.

[0003] In existing technologies, some equipment attempts to suppress odor diffusion through covering membranes or sealing devices. However, static sealing structures are difficult to adapt to fluctuations in the leachate surface, resulting in insufficient airtightness. Odors easily escape into the environment during gas-liquid separation, leading to prominent odor problems in the work area. Furthermore, although ozone oxidation technology is used for deodorization, conventional designs often separate ozone administration from the gas-liquid separation process, resulting in low ozone utilization and preventing simultaneous gas-liquid treatment. Therefore, a landfill leachate treatment device with deodorization capabilities is needed to solve these problems. Utility Model Content

[0004] This invention proposes a landfill leachate treatment device with deodorization function, which makes the covering membrane adhere to the liquid surface fluctuation to form a dynamic sealing barrier; at the same time, the rubber annular air tube is inflated and then comes into close contact with the inner wall of the gas-liquid isolation chamber, further enhancing the edge airtightness and effectively preventing the odor from escaping. Moreover, the oxidative decomposition of odor and the preliminary treatment of leachate can be completed simultaneously in the gas-liquid isolation chamber.

[0005] This utility model is implemented as follows: a landfill leachate treatment device with deodorization function includes a gas-liquid isolation chamber, and a gas-liquid separation device is provided inside the gas-liquid isolation chamber. The gas-liquid separation device includes an ozone generator installed on the outer wall of the gas-liquid isolation chamber. An aeration pipe is connected to the outer wall of the ozone generator. The other end of the aeration pipe penetrates the gas-liquid isolation chamber and extends into its interior. Multiple evenly distributed aeration heads are provided on the outer wall of the aeration pipe. Two symmetrically distributed supports are fixedly connected to the upper end of the gas-liquid isolation chamber. Electric actuators are installed at the upper ends of both supports. The output ends of both electric actuators penetrate the supports and the gas-liquid isolation chamber and are fixedly connected to a support plate. A covering membrane is fixedly connected to the lower end of the support plate. A rubber annular air pipe is fixedly connected to the outer wall of the covering membrane. An air pump is installed on the outer wall of the support at the left end. A delivery pipe is connected to the outer wall of the air pump. A through hole is opened at the upper end of the gas-liquid isolation chamber. The other end of the delivery pipe passes through the through hole and connects to the rubber annular air pipe. A drain pipe is fixedly connected through the middle of the covering membrane and the support plate. A fan is connected to the upper end of the drain pipe, and an auxiliary pipe is connected to the outlet of the fan.

[0006] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function according to this utility model, a level gauge is preferably installed at the lower end of the covering membrane.

[0007] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function of this utility model, the left end of the gas-liquid isolation chamber is connected to a liquid inlet hopper, and the upper end of the liquid inlet hopper is threadedly connected to a sealing cap.

[0008] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function of this utility model, a treatment tank is preferably provided on the left side of the gas-liquid isolation chamber. The left end of the auxiliary pipe penetrates and extends into the interior of the treatment tank and is fixedly connected to a diversion plate. Multiple evenly distributed diversion pipes are installed on the outer wall of the diversion plate. A reagent tank is provided on the left end of the treatment tank. An infusion pipe is connected to the outer wall of the reagent tank. The other end of the infusion pipe extends into the interior of the treatment tank and is connected to a spray plate with multiple nozzles.

[0009] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function according to this utility model, the treatment tank is preferably equipped with an activated carbon filter plate located above the spray plate.

[0010] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function of this utility model, the drainage pipe is an elastic telescopic pipe.

[0011] As a preferred embodiment of the landfill leachate treatment equipment with deodorization function of this utility model, the outer wall of the gas-liquid isolation chamber is connected to a drain pipe, and the upper end of the treatment tank is connected to an exhaust pipe.

[0012] The beneficial effects of this utility model are: The support plate is driven by an electric actuator to raise and lower the covering membrane. In conjunction with the liquid level gauge to monitor the liquid level in real time, the covering membrane is made to fit the liquid surface fluctuations to form a dynamic sealing barrier. At the same time, the rubber ring air tube is inflated and then makes close contact with the inner wall of the gas-liquid isolation chamber, further enhancing the edge airtightness and effectively preventing the escape of odor. The ozone generator releases ozone evenly into the leachate through aeration pipes and aeration heads, simultaneously completing the oxidation and decomposition of odor and the preliminary treatment of leachate within the gas-liquid isolation chamber, thereby improving ozone utilization. The isolation effect of the covering membrane extends the contact time between ozone and odor, enhancing the degradation effect of malodorous substances (such as hydrogen sulfide and ammonia), and achieving simultaneous gas-liquid treatment.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 A landfill leachate treatment device with deodorization function includes a gas-liquid isolation chamber 1, and a gas-liquid separation device is installed inside the gas-liquid isolation chamber 1. The gas-liquid separation device includes an ozone generator 3 installed on the outer wall of the gas-liquid isolation chamber 1. An aeration pipe 4 is connected to the outer wall of the ozone generator 3. The other end of the aeration pipe 4 passes through the gas-liquid isolation chamber 1 and extends into its interior. Multiple evenly distributed aeration heads 5 are installed on the outer wall of the aeration pipe 4. Two symmetrically distributed supports 8 are fixedly connected to the upper end of the gas-liquid isolation chamber 1. Electric actuators 9 are installed on the upper ends of both supports 8. The output ends of both electric actuators 9 pass through the supports 8 and the gas-liquid isolation chamber 1 and are fixedly connected to a support plate 10. A covering membrane 6 is fixedly connected to the lower end of the support plate 10. A rubber annular air pipe 7 is fixedly connected to the outer wall of the covering membrane 6. An air pump 11 is installed on the outer wall of the left end bracket 8. A delivery pipe 12 is connected to the outer wall of the air pump 11. A through hole is opened at the upper end of the gas-liquid isolation chamber 1. The other end of the delivery pipe 12 is connected to the rubber annular air pipe 7 through the through hole. A drainage pipe 20 is fixedly connected through the middle of the covering membrane 6 and the support plate 10. A fan 21 is connected to the upper end of the drainage pipe 20. An auxiliary pipe 22 is connected to the air outlet of the fan 21.

[0020] In this embodiment: after the leachate enters the gas-liquid isolation chamber 1 through the inlet hopper 2, the liquid level gauge 19 at the lower end of the cover membrane 6 monitors the liquid level and transmits the signal to the electric actuator 9 through the controller in the prior art. The electric actuator 9 drives the support plate 10 to rise and fall according to the liquid level change, so that the cover membrane 6 always adheres to the liquid surface and forms a dynamic sealing barrier. The air pump 11 inflates the rubber annular air pipe 7 through the delivery pipe 12, so that it expands and comes into close contact with the inner wall of the gas-liquid isolation chamber 1, further strengthening the edge sealing and preventing odor from escaping from the gap between the cover membrane 6 and the chamber wall. The ozone generated by the ozone generator 3 is transported to the gas-liquid isolation chamber 1 through the aeration pipe 4. It is then evenly released through multiple aeration heads 5 and reacts with organic matter and malodorous substances (such as hydrogen sulfide and ammonia) in the leachate to undergo an oxidation reaction. The covering membrane 6 isolates the gas treated by ozone from the liquid, prolongs the gas residence time, improves the ozone utilization rate and odor decomposition efficiency, and achieves simultaneous gas-liquid treatment.

[0021] As a technical optimization of this utility model, a level gauge 19 is installed at the lower end of the covering membrane 6.

[0022] In this embodiment, the liquid level inside the gas-liquid isolation chamber 1 can be conveniently monitored by the liquid level gauge 19.

[0023] As a technical optimization of this utility model, the left end of the gas-liquid isolation chamber 1 is connected to the liquid inlet 2, and the upper end of the liquid inlet 2 is threadedly connected to the sealing cap.

[0024] In this embodiment, the liquid inlet hopper 2 can be initially sealed by the sealing cap to prevent the spread of odor.

[0025] As a technical optimization of this utility model, a treatment tank 13 is provided on the left side of the gas-liquid isolation chamber 1. The left end of the auxiliary pipe 22 passes through and extends into the interior of the treatment tank 13 and is fixedly connected to a diversion plate 23. Multiple evenly distributed diversion pipes are installed on the outer wall of the diversion plate 23. A medicine tank 14 is provided on the left end of the treatment tank 13. An infusion pipe 15 is connected to the outer wall of the medicine tank 14. The other end of the infusion pipe 15 extends into the interior of the treatment tank 13 and is connected to a spray plate 16 with multiple nozzles.

[0026] In this embodiment: the fan 21 draws the residual odor in the gas-liquid isolation chamber 1 to the treatment tank 13 through the diversion pipe 20 with elastic telescopic structure. The diversion pipe on the auxiliary pipe 22 evenly disperses the gas into the treatment tank 13. The agent tank 14 delivers neutralizing agent (such as sodium hypochlorite solution) to the spray plate 16 through the infusion pipe 15. After being atomized by the nozzle, it comes into full contact with the odor to neutralize acidic or alkaline pollutants.

[0027] As a technical optimization of this utility model, the interior of the treatment tank 13 is provided with an activated carbon filter plate 17 located above the spray plate 16.

[0028] In this embodiment: during the gas rise process, residual odors and particulate matter are adsorbed by the activated carbon filter plate 17, and the finally purified gas is discharged through the exhaust pipe 18 in compliance with standards.

[0029] As a technical optimization of this utility model, the drainage tube 20 is an elastic telescopic tube.

[0030] In this embodiment, the drainage tube 20 is an elastic telescopic tube, which allows the drainage tube 20 to easily move in a telescopic motion as the covering film 6 moves.

[0031] As a technical optimization of this utility model, the outer wall of the gas-liquid isolation chamber 1 is connected to a drain pipe, and the upper end of the treatment tank 13 is connected to an exhaust pipe 18.

[0032] In this embodiment: the drain pipe can discharge the treated liquid, and the exhaust pipe 18 can discharge the treated gas.

[0033] The working principle and usage process of this utility model are as follows: After the leachate enters the gas-liquid isolation chamber 1 through the inlet hopper 2, the liquid level gauge 19 at the lower end of the covering membrane 6 monitors the liquid level in real time and transmits the signal to the electric actuator 9. The electric actuator 9 drives the support plate 10 to rise and fall according to the liquid level change, so that the covering membrane 6 always adheres to the liquid surface, forming a dynamic sealing barrier. The air pump 11 inflates the rubber annular air pipe 7 through the delivery pipe 12, causing it to expand and make close contact with the inner wall of the gas-liquid isolation chamber 1, further strengthening the edge sealing and preventing odor from escaping from the gap between the covering membrane 6 and the chamber wall. The ozone generated by the ozone generator 3 is delivered to the gas-liquid isolation chamber 1 through the aeration pipe 4 and is evenly released through multiple aeration heads 5, where it oxidizes the organic matter and malodorous substances (such as hydrogen sulfide and ammonia) in the leachate. In the reaction, the covering membrane 6 isolates the ozone-treated gas from the liquid, prolonging the gas residence time and improving the ozone utilization rate and odor decomposition efficiency. The treated leachate is discharged through the drain pipe at the bottom of the gas-liquid isolation chamber 1 and enters the subsequent treatment process. The blower 21 draws the residual odor in the gas-liquid isolation chamber 1 to the treatment tank 13 through the elastic telescopic structure of the diversion pipe 20. The diversion pipe on the auxiliary pipe 22 evenly disperses the gas into the treatment tank 13. The reagent tank 14 delivers neutralizing agent (such as sodium hypochlorite solution) to the spray plate 16 through the infusion pipe 15. After being atomized by the nozzle, it comes into full contact with the odor to neutralize acidic or alkaline pollutants. During the gas rise, the residual odor and particulate matter are adsorbed by the activated carbon filter plate 17. Finally, the purified gas is discharged through the exhaust pipe 18 in compliance with standards.
