Description

Technical Field

[0001] The invention relates to the field of garbage disposal, in particular to a leachate treatment station for a domestic garbage incineration power plant. Background Art

[0002] Garbage leachate refers to a high-concentration wastewater formed by the water contained in the garbage itself in the landfill, the rain and snow water entering the landfill, and other water, minus the saturated water holding capacity of the garbage and the overburden layer, and passing through the garbage layer and the overburden layer. The water quality of garbage leachate is quite complex, generally containing high concentrations of organic matter, heavy metal salts, SS and ammonia nitrogen. Garbage leachate not only pollutes the soil and surface water sources, but also pollutes groundwater. Conventional treatment methods include biochemical method, membrane method, and Dusheng ion exchange method.

[0003] In the related art, a leachate treatment system and method for a waste incineration power plant are proposed, including a leachate collection module, an ultraviolet pretreatment module and an NBR membrane treatment module. The output end of the leachate collection module is connected to the ultraviolet pretreatment module, and the output end of the ultraviolet pretreatment module is connected to the NBR membrane treatment module. The ultraviolet pretreatment module includes a boring body, a first ultraviolet light module and a second ultraviolet light module. The first ultraviolet light component is rotatably installed on the tank body, and the rotation axis of the first ultraviolet light component is set along the height direction of the tank body. The second ultraviolet light module is divided into two groups, and the two groups of second ultraviolet light modules are arranged on both sides of the tank body. The second ultraviolet light modules can be slidably fitted on the tank body.

[0004] The above-mentioned related technologies have the following defects: ultraviolet treatment of leachate in the tank body not only occupies a large area, but also a large amount of leachate accumulates in the tank body. The light transmittance of ultraviolet rays is limited, resulting in incomplete treatment and time-consuming and labor-intensive. Summary of the invention

[0005] In order to improve the effect of ultraviolet treatment and reduce the occupied area, the present invention provides a leachate treatment station for a domestic waste incineration power plant.

[0006] The present invention provides a leachate treatment station for a domestic waste incineration power plant, which adopts the following technical solution:

[0007] A leachate treatment station for a domestic waste incineration power plant comprises a collection module, wherein the collection module comprises a collection tank;

[0008] An ultraviolet treatment module, the ultraviolet treatment module comprises a pump body, a delivery pipe and an ultraviolet lamp, the outlet of the collection pool is connected to the inlet of the pump body, the outlet of the pump body is connected to the inlet of the delivery pipe, the delivery pipe is transparent, the ultraviolet lamp is arranged on the delivery pipe, and the ultraviolet lamp extends along the length direction of the delivery pipe; and,

[0009] The membrane treatment module, the outlet of the delivery pipe is connected with the inlet of the membrane treatment module.

[0010] By adopting the above technical solution, the collection tank is used as the core part of the collection module, and its main function is to collect the leachate generated from the domestic waste incineration power plant, providing a centralized source for the subsequent treatment of the leachate, ensuring that all the leachate that needs to be treated can be effectively collected, and the pump body starts working, and uses its own suction capacity to suck the leachate in the collection tank from the outlet of the collection tank to the inlet of the pump body, and then through the pressurization of the pump body, the leachate is pushed from the outlet of the pump body to the inlet of the delivery pipe, so that the leachate can flow along the delivery pipe under pressure. When the leachate flows in the transparent delivery pipe, the ultraviolet lamps extending along the length of the delivery pipe are turned on at the same time and emit ultraviolet rays, thereby achieving the killing and inhibition of microorganisms in the leachate, and achieving the purpose of preliminary purification of the leachate. The leachate treated by the ultraviolet treatment module flows out from the outlet of the delivery pipe, and then enters the inlet of the membrane treatment module, thereby achieving fine treatment of the leachate and obtaining treated water that meets the emission standards or reuse requirements.

[0011] Preferably, a reflective tube is sleeved on the conveying tube, the reflective tube extends along the length direction of the conveying tube, the reflective tube and the conveying tube are in a hollow state, the ultraviolet lamp is located between the conveying tube and the reflective tube, the ultraviolet lamp is arranged on the reflective tube, and the reflective tube is used to concentrate the ultraviolet rays generated by the ultraviolet lamp into the conveying tube.

[0012] By adopting the above technical scheme, the ultraviolet lamp is installed on the reflective tube and is located in the hollow area between the conveying tube and the reflective tube. When the ultraviolet lamp is powered on, it will emit ultraviolet rays in all directions. Due to its special position, the ultraviolet rays will radiate in multiple directions such as the conveying tube and the reflective tube. Since the reflective tube extends along the length direction of the conveying tube and is in a shape surrounding the conveying tube and the ultraviolet lamp, most of the ultraviolet rays emitted from the ultraviolet lamp and directed to the reflective tube will be reflected into the conveying tube after reflection, so that the ultraviolet rays originally scattered in all directions are more concentrated in the internal area of ​​the conveying tube, thereby improving the intensity and density of the ultraviolet rays in the conveying tube. During the leachate treatment process, when the leachate flows in the conveying tube, due to the increase in the intensity and density of the ultraviolet rays in the conveying tube, the pollutants such as microorganisms and organic matter in the leachate can be more fully irradiated by ultraviolet rays, thereby enhancing the treatment effect on the leachate, and improving the treatment efficiency and purification degree.

[0013] Preferably, the reflective tube is provided with an air blowing assembly for dissipating heat and cleaning the ultraviolet lamp tube, the air blowing assembly includes a fan, a guide cavity is formed between the reflective tube and the conveying tube, an air inlet and an air outlet are respectively provided at both ends of the guide cavity, and the outlet of the fan is connected to the air inlet.

[0014] By adopting the above technical solution, after the fan is started, under the action of atmospheric pressure, the outside air is continuously sucked into the inlet of the fan. Since the outlet of the fan is connected with the air inlet of the guide cavity formed between the reflective tube and the conveying tube, the pressurized air flows into the air inlet along the connecting pipe and enters the guide cavity. Under the action of the pressure difference, the air entering the guide cavity flows from the air inlet to the air outlet along the guide cavity. During the flow process, the air will fully contact with the ultraviolet lamp tube. The ultraviolet lamp tube will generate heat when working, and the heat will be dissipated into the surrounding environment. When the air flows through the ultraviolet lamp tube, the air will absorb the heat on the surface of the ultraviolet lamp tube, thereby increasing the temperature of the ultraviolet lamp tube. The temperature is reduced, which plays a role in heat dissipation. This helps prevent the UV lamp from being damaged due to overtemperature and prolongs its service life. It also ensures that the UV lamp works in a relatively stable temperature environment to maintain its normal luminous efficiency and bactericidal and disinfecting performance. Due to the flow of air, the dust and other impurities in the diversion cavity will move together. For dust and other pollutants that may be attached to the surface of the UV lamp, the flowing air can blow them away from the surface of the UV lamp to play a cleaning role. This can keep the surface of the UV lamp clean and ensure that the ultraviolet rays can be emitted smoothly without being blocked or absorbed by dust and other impurities, thereby ensuring that the treatment effect of the leachate in the delivery pipe is not affected.

[0015] Preferably, a filter is provided on the air inlet.

[0016] By adopting the above technical solution, the outside air often contains dust, fluff, small particles of impurities, etc. The filter can effectively block these impurities outside the air inlet, preventing them from entering the guide cavity formed between the reflective tube and the delivery tube with the air. If there is no filter, once these impurities enter the guide cavity, they may adhere to the surface of the ultraviolet lamp and affect the emission effect of ultraviolet rays. They may also accumulate in the guide cavity and affect the normal flow of air, thereby interfering with the heat dissipation and cleaning function of the blower assembly on the ultraviolet lamp.

[0017] Preferably, the filter screen is rotatably connected to an impeller, a brush is coaxially provided on the impeller, and the brush abuts against the outer side of the filter screen.

[0018] By adopting the above technical solution, when the air blowing assembly is working, the fan draws in outside air and delivers it to the air inlet. In the process of air passing through the filter and entering the air inlet, a certain pressure difference will be formed on both sides of the filter due to the blocking effect of the filter on the air. This pressure difference will prompt the air to try to pass through the mesh of the filter at a faster speed. The impeller is installed on the filter. The airflow impact force generated when the air passes through the filter and the driving force formed by the pressure difference will act on the impeller, causing the impeller to start rotating around its own axis. As the impeller rotates continuously under the action of the air pressure difference and the airflow impact force Since the brush and the impeller are coaxially arranged, the rotational power of the impeller will be directly transmitted to the brush, so that the brush will rotate synchronously with the impeller. During the rotation of the brush, its bristles will continuously contact and rub against the outer surface of the filter. Since the brush abuts against the filter, this contact can effectively clean up impurities such as dust and fluff that may be attached to the outer surface of the filter. After these impurities are cleaned up by the brush, they will be carried away from the vicinity of the filter through air flow and other means, thereby keeping the surface of the filter clean and preventing impurities from accumulating on the filter and affecting the filtering effect of the filter.

[0019] Preferably, a dustproof plate is rotatably connected to the air outlet, and a torsion spring is provided between the dustproof plate and the air outlet, one end of the torsion spring is connected to the dustproof plate, and the other end of the torsion spring is connected to the air outlet. The torsion spring causes the dustproof plate to tend to rotate toward the air outlet, and the torsion force of the torsion spring is smaller than the wind force generated by the fan.

[0020] By adopting the above technical solution, the dustproof plate is rotatably connected to the air outlet through the torsion spring. When the blowing assembly is not working, due to the action of the torsion spring, the dustproof plate tends to rotate toward the air outlet, so that the air outlet is in a blocked state. This can prevent external dust, debris, etc. from entering the guide cavity through the air outlet when the equipment is not running, thereby protecting the internal ultraviolet lamp tube and air flow channel. When the fan starts working, the wind force generated by the fan flows toward the air outlet through the guide cavity. Since the wind force generated by the fan is greater than the torsion force of the torsion spring, the wind force acts on the dustproof plate, overcomes the torsion force of the torsion spring, and causes the dustproof plate to rotate in the direction away from the air outlet, thereby opening the air outlet. At this time, The air can be smoothly discharged from the guide cavity through the air outlet to the outside. During the continuous operation of the fan, the continuous wind force keeps the dustproof plate in the open state. The air flows in the guide cavity, and after completing the heat dissipation and cleaning of the ultraviolet lamp tube, it is discharged from the air outlet. The dustproof plate is stably in the open position under the action of wind force and will not affect the normal discharge of air. When the fan stops working, the wind force generated by the fan disappears. At this time, the torsion force of the torsion spring begins to play a role. Since the torsion spring makes the dustproof plate tend to rotate toward the air outlet, the dustproof plate rotates again under the action of the torsion force of the torsion spring and returns to the initial state of blocking the air outlet, preventing external dust and other impurities from entering the guide cavity until the next time the fan is started.

[0021] Preferably, a uniform fan is rotatably connected in the guide cavity, and the uniform fan faces the air inlet.

[0022] By adopting the above technical solution, when the fan blows air into the guide cavity through the air inlet, the flow state of the air just entering may be relatively chaotic, and the speed and pressure distribution are uneven. The rotation of the fan can stir and guide the air entering the guide cavity, so that the air forms a more uniform and stable airflow distribution in the guide cavity. In this way, it can be ensured that when the air flows through the ultraviolet lamp tube, the lamp tube in each part can be blown by uniform airflow, achieving a more balanced heat dissipation effect, avoiding the problem of lamp tube overheating caused by local poor airflow, and extending the overall service life of the ultraviolet lamp tube.

[0023] Preferably, the ultraviolet treatment module also includes a shunt pipe, which includes an upper pipe and a lower pipe, the outlet of the delivery pipe is connected to the inlets of the upper pipe and the lower pipe at the same time, the outlet of the upper pipe is connected to the inlet of the membrane treatment module, and the outlet of the lower pipe is connected to the inlet of the collection tank, the upper pipe is used to transport the supernatant, and the lower pipe is used to return the precipitate to the collection tank.

[0024] By adopting the above technical scheme, when passing through the delivery pipe in the ultraviolet treatment module, some substances in the leachate will undergo a certain degree of aggregation, precipitation or stratification under ultraviolet irradiation and some possible physical and chemical effects. Some larger particles of impurities and heavier sediments will gradually settle to the bottom of the delivery pipe, while the relatively lighter and clearer supernatant will be located at the upper part. When the leachate reaches the outlet of the delivery pipe and enters the diversion pipe, due to the special layout and connection method of the upper and lower pipes, based on gravity and the flow characteristics of the liquid itself, diversion will naturally occur. The relatively clear supernatant located at the upper part of the delivery pipe will preferentially flow into the upper pipe under the influence of gravity and the liquid flow direction and pressure distribution at the outlet of the delivery pipe, while the sediment located at the bottom of the delivery pipe will flow into the lower pipe under the action of gravity because it is heavier and close to the inlet of the lower pipe. Through this working principle of the diversion pipe, the initial separation and reasonable diversion of the leachate after ultraviolet treatment are achieved, thereby improving the treatment efficiency of the entire leachate treatment station and the operating stability of the membrane treatment module.

[0025] Preferably, an adjustment plate is rotatably connected to the inlet of the upper tube and the lower tube, and a driving assembly is provided on the conveying tube, and the driving assembly is used to drive the adjustment plate to rotate, thereby adjusting the opening size of the upper tube and the lower tube.

[0026] By adopting the above technical solution, the adjustment plate is located at the inlet of the upper tube and the lower tube and is rotatably connected thereto. This rotational movement can change the opening size of the inlet of the upper tube and the lower tube. The driving assembly is installed on the conveying pipe. Its main purpose is to provide power for the adjustment plate so that the adjustment plate can rotate. The initial state of the adjustment plate is at a certain angle to the inlet of the upper tube and the lower tube, so that the inlet has an initial opening size. When the driving assembly drives the adjustment plate to rotate in one direction, the adjustment plate will gradually block the inlet of the upper tube and the lower tube, thereby making the opening smaller. On the contrary, when the driving assembly drives the adjustment plate to rotate in another direction, the adjustment plate will gradually move away from the originally blocked part of the inlet of the upper tube and the lower tube, thereby making the opening larger. In this way, the opening size of the upper tube and the lower tube can be accurately adjusted according to actual work needs to control the material flow or other fluid flow through the pipeline.

[0027] Preferably, the driving assembly includes a motor disposed on the conveying pipe, the output shaft of the motor penetrates into the conveying pipe, and the output shaft of the motor is connected to the adjustment plate.

[0028] By adopting the above technical solution, the motor is installed on the conveying pipe as a power source, and the output shaft of the motor penetrates into the conveying pipe and is connected to the adjustment plate. In this way, the rotational movement of the motor output shaft is directly transmitted to the adjustment plate. Since the adjustment plate is rotatably connected to the inlet of the upper tube and the lower tube, the adjustment plate can rotate around the connection point with the inlet under the drive of the motor output shaft. When the motor rotates forward, the motor output shaft drives the adjustment plate to rotate in one direction. Conversely, when the motor rotates reversely, the motor output shaft drives the adjustment plate to rotate in the opposite direction.

[0029] In summary, the present invention includes at least one of the following beneficial technical effects:

[0030] When the leachate flows in the transparent conveying pipe, the ultraviolet lamps extending along the length of the conveying pipe are turned on at the same time and emit ultraviolet rays, thereby killing and inhibiting the microorganisms in the leachate, achieving the purpose of preliminary purification of the leachate. The ultraviolet treatment of the leachate is realized during the flow and transportation of the leachate, which reduces the footprint and improves the treatment efficiency.

[0038] The following is combined with Figure 1-5 The present invention is described in further detail.

[0039] The present invention provides a leachate treatment station for a domestic waste incineration power plant, the structure of which is as follows: Figure 1 - Figure 2 As shown, it includes a collection module 1, an ultraviolet treatment module 2 and a membrane treatment module 3.

[0040] The collection module 1 includes a collection pool 11 .

[0041] The ultraviolet treatment module 2 includes a pump body 21, a delivery pipe 22 and an ultraviolet lamp 23. The outlet of the collection pool 11 is connected to the inlet of the pump body 21, and the outlet of the pump body 21 is connected to the inlet of the delivery pipe 22. The delivery pipe 22 is transparent. The ultraviolet lamp 23 is arranged on the delivery pipe 22, and the ultraviolet lamp 23 extends along the length direction of the delivery pipe 22.

[0042] The outlet of the delivery pipe 22 is connected to the inlet of the membrane treatment module 3 .

[0043] When in use, the collection tank 11 is the core part of the collection module 1, and its main function is to collect the leachate generated from the domestic waste incineration power plant, providing a centralized source for the subsequent treatment of the leachate, ensuring that all the leachate that needs to be treated can be effectively collected. The pump body 21 starts working and uses its own suction capacity to suck the leachate in the collection tank 11 from the outlet of the collection tank 11 to the inlet of the pump body 21, and then through the pressurization of the pump body 21, the leachate is pushed from the outlet of the pump body 21 to the inlet of the delivery pipe 22. The leachate is driven by pressure to flow along the delivery pipe 22. When the leachate flows in the transparent delivery pipe 22, the ultraviolet lamps 23 extending along the length direction of the delivery pipe 22 are turned on at the same time and emit ultraviolet rays, thereby killing and inhibiting the microorganisms in the leachate, thereby achieving the purpose of preliminary purification of the leachate. The leachate treated by the ultraviolet treatment module 2 flows out from the outlet of the delivery pipe 22, and then enters the inlet of the membrane treatment module 3, thereby achieving fine treatment of the leachate and obtaining treated water that meets the discharge standards or reuse requirements.

[0044] In the present invention, when the leachate flows in the transparent delivery pipe 22, the ultraviolet lamp tubes 23 extending along the length direction of the delivery pipe 22 are turned on at the same time and emit ultraviolet rays, thereby killing and inhibiting the microorganisms in the leachate, achieving the purpose of preliminary purification of the leachate, and realizing ultraviolet treatment of the leachate during the flow and transportation of the leachate, thereby reducing the occupied area and improving the treatment efficiency.

[0045] To enhance the effect of UV radiation, please refer to Figure 2 In a preferred embodiment, a reflective tube 24 is sleeved on the delivery tube 22, and the reflective tube 24 extends along the length direction of the delivery tube 22. The reflective tube 24 and the delivery tube 22 are in a hollow state. The ultraviolet lamp 23 is located between the delivery tube 22 and the reflective tube 24. The ultraviolet lamp 23 is arranged on the reflective tube 24, and the reflective tube 24 is used to concentrate the ultraviolet light generated by the ultraviolet lamp 23 into the delivery tube 22.

[0046] When in use, the ultraviolet lamp 23 is installed on the reflective tube 24 and is located in the hollow area between the conveying tube 22 and the reflective tube 24. When the ultraviolet lamp 23 is powered on, it will emit ultraviolet rays in all directions. Due to its special position, the ultraviolet rays will radiate in multiple directions such as the conveying tube 22 and the reflective tube 24. Since the reflective tube 24 extends along the length direction of the conveying tube 22 and is in a shape that surrounds the conveying tube 22 and the ultraviolet lamp 23, most of the ultraviolet rays emitted from the ultraviolet lamp 23 and directed toward the reflective tube 24 will be reflected into the conveying tube 22 after reflection, so that the ultraviolet rays originally scattered in all directions are more concentrated in the internal area of ​​the conveying tube 22, thereby improving the intensity and density of the ultraviolet rays in the conveying tube 22. During the leachate treatment process, when the leachate flows in the conveying tube 22, due to the increase in the intensity and density of the ultraviolet rays in the conveying tube 22, the pollutants such as microorganisms and organic matter in the leachate can be more fully irradiated by ultraviolet rays, thereby enhancing the treatment effect on the leachate, and improving the treatment efficiency and purification degree.

[0047] To clean and cool the UV lamp 23, please refer to Figure 2 In a preferred embodiment, the reflective tube 24 is provided with a blower assembly 4 for dissipating heat and cleaning the ultraviolet lamp tube 23, and the blower assembly 4 includes a fan 41. A guide cavity 42 is formed between the reflective tube 24 and the conveying pipe 22, and an air inlet 43 and an air outlet 44 are respectively provided at both ends of the guide cavity 42. The outlet of the fan 41 is connected to the air inlet 43.

[0048] When in use, after the fan 41 is started, under the action of atmospheric pressure, external air is continuously sucked into the inlet of the fan 41. Since the outlet of the fan 41 is connected with the air inlet 43 of the guide cavity 42 formed between the reflective tube 24 and the delivery tube 22, the pressurized air flows into the air inlet 43 along the connecting pipe and enters the guide cavity 42. Under the action of pressure difference, the air entering the guide cavity 42 flows from the air inlet 43 to the air outlet 44 along the guide cavity 42. During the flow process, the air will fully contact with the ultraviolet lamp tube 23. The ultraviolet lamp tube 23 will generate heat when working, and the heat will be dissipated into the surrounding environment. When the air flows through the ultraviolet lamp tube 23, the air will absorb the heat on the surface of the ultraviolet lamp tube 23, thereby making the ultraviolet The temperature of the external lamp tube 23 is reduced, which plays a role in heat dissipation, which helps to prevent the ultraviolet lamp tube 23 from being damaged due to excessive temperature and prolong its service life. At the same time, it can also ensure that the ultraviolet lamp tube 23 works in a relatively stable temperature environment to maintain its normal luminous efficiency and sterilization and disinfection performance. Due to the flow of air, the dust and other impurities in the guide cavity 42 will be driven to move together. For dust and other pollutants that may be attached to the surface of the ultraviolet lamp tube 23, the flowing air can blow them away from the surface of the ultraviolet lamp tube 23, which plays a cleaning role. In this way, the surface of the ultraviolet lamp tube 23 can be kept clean, ensuring that the ultraviolet rays can be smoothly emitted without being blocked or absorbed by impurities such as dust, thereby ensuring that the treatment effect of the leachate in the delivery pipe 22 is not affected.

[0049] To reduce the possibility of dust entering the guide cavity 42, please refer to Figure 3 In a preferred embodiment, a filter 45 is provided on the air inlet 43 .

[0050] When in use, the outside air often contains dust, fluff, small particles of impurities, etc. The filter 45 can effectively block these impurities outside the air inlet 43, preventing them from entering the guide cavity 42 formed between the reflective tube 24 and the delivery tube 22 with the air. If there is no filter 45, once these impurities enter the guide cavity 42, they may adhere to the surface of the ultraviolet lamp 23 and affect the emission effect of ultraviolet rays. They may also accumulate in the guide cavity 42 and affect the normal flow of air, thereby interfering with the heat dissipation and cleaning function of the blower assembly 4 on the ultraviolet lamp 23.

[0051] To clean the filter 45, refer to Figure 3 In a preferred embodiment, the filter screen 45 is rotatably connected to an impeller 46 , and a brush 47 is coaxially provided on the impeller 46 , and the brush 47 abuts against the outer side of the filter screen 45 .

[0052] During use, when the blower assembly 4 is working, the fan 41 draws in outside air and delivers it to the air inlet 43. In the process of air passing through the filter 45 and entering the air inlet 43, a certain pressure difference will be formed on both sides of the filter 45 due to the blocking effect of the filter 45 on the air. This pressure difference will prompt the air to try to pass through the mesh of the filter 45 at a faster speed. The impeller 46 is installed on the filter 45. The airflow impact force generated when the air passes through the filter 45 and the driving force formed by the pressure difference will act on the impeller 46, causing the impeller 46 to start rotating around its own axis. As the impeller 46 continues to rotate under the action of the air pressure difference and the airflow impact force, the brush 47 is coaxially arranged with the impeller 46, and the rotational power of the impeller 46 will be directly transmitted to the brush 47, so that the brush 47 will also rotate synchronously with the impeller 46. During the rotation of the brush 47, the bristles of the brush 47 will constantly contact and rub against the outer surface of the filter 45. Since the brush 47 abuts against the filter 45, this contact can effectively clean up the dust, fluff and other impurities that may be attached to the outer surface of the filter 45. After these impurities are cleaned up by the brush 47, they will be carried away from the vicinity of the filter 45 by air flow and other means, thereby keeping the surface of the filter 45 clean and preventing impurities from accumulating on the filter 45 and affecting the filtering effect of the filter 45.

[0053] To further reduce the possibility of dust entering the guide cavity 42, please refer to Figure 4 In a preferred embodiment, a dustproof plate 48 is rotatably connected to the air outlet 44, and a torsion spring 49 is provided between the dustproof plate 48 and the air outlet 44. One end of the torsion spring 49 is connected to the dustproof plate 48, and the other end of the torsion spring 49 is connected to the air outlet 44. The torsion spring 49 causes the dustproof plate 48 to tend to rotate toward the air outlet 44, and the torque of the torsion spring 49 is smaller than the wind force generated by the fan 41.

[0054] When in use, the dustproof plate 48 is rotatably connected to the air outlet 44 by the torsion spring 49. When the blower assembly 4 is not working, due to the action of the torsion spring 49, the dustproof plate 48 tends to rotate toward the air outlet 44, so that the air outlet 44 is in a blocked state. This can prevent external dust, debris, etc. from entering the guide cavity 42 through the air outlet 44 when the equipment is not running, thereby protecting the internal ultraviolet lamp tube 23 and the air flow channel. When the fan 41 starts to work, the wind force generated by the fan 41 flows toward the air outlet 44 through the guide cavity 42. Since the wind force generated by the fan 41 is greater than the torsion force of the torsion spring 49, the wind force acts on the dustproof plate 48, overcomes the torsion force of the torsion spring 49, and causes the dustproof plate 48 to rotate in the direction away from the air outlet 44, thereby opening the air outlet 44. At this time, the air The air can be smoothly discharged from the guide cavity 42 to the outside through the air outlet 44. During the continuous operation of the fan 41, the continuous wind force keeps the dustproof plate 48 in an open state. The air flows in the guide cavity 42, and after completing the heat dissipation and cleaning of the ultraviolet lamp 23, it is discharged from the air outlet 44. The dustproof plate 48 is stably in the open position under the action of the wind force and will not affect the normal discharge of air. When the fan 41 stops working, the wind force generated by the fan 41 disappears. At this time, the torsion force of the torsion spring 49 begins to play a role. Since the torsion spring 49 makes the dustproof plate 48 tend to rotate toward the air outlet 44, the dustproof plate 48 rotates again under the action of the torsion force of the torsion spring 49 and returns to the initial state of blocking the air outlet 44, preventing external dust and other impurities from entering the guide cavity 42 until the next time the fan 41 is started.

[0055] In order to make the airflow in the guide cavity 42 more uniform, please refer to Figure 2 In a preferred embodiment, a uniform fan 5 is rotatably connected in the guide cavity 42 , and the uniform fan 5 faces the air inlet 43 .

[0056] During use, when the fan 41 blows air into the guide cavity 42 through the air inlet 43, the flow state of the air just entering may be relatively chaotic, and the speed and pressure distribution are uneven. The rotation of the fan 5 can stir and guide the air entering the guide cavity 42, so that the air forms a more uniform and stable airflow distribution in the guide cavity 42. In this way, it can be ensured that when the air flows through the ultraviolet lamp tube 23, the lamp tubes in various parts can be blown by uniform airflow, achieving a more balanced heat dissipation effect, avoiding the problem of lamp tube overheating caused by local poor airflow, and extending the overall service life of the ultraviolet lamp tube 23.

[0057] To return the sediment to the collection tank 11, please refer to Figure 5In a preferred embodiment, the ultraviolet treatment module 2 also includes a shunt pipe 6, which includes an upper pipe 61 and a lower pipe 62. The outlet of the delivery pipe 22 is connected to the inlets of the upper pipe 61 and the lower pipe 62 at the same time. The outlet of the upper pipe 61 is connected to the inlet of the membrane treatment module 3, and the outlet of the lower pipe 62 is connected to the inlet of the collection tank 11. The upper pipe 61 is used to transport the supernatant, and the lower pipe 62 is used to return the precipitate to the collection tank 11.

[0058] When in use, when passing through the delivery pipe 22 in the ultraviolet treatment module 2, some substances in the leachate will undergo a certain degree of aggregation, precipitation or stratification under the irradiation of ultraviolet rays and some possible physical and chemical effects. Some larger particles of impurities and heavier sediments will gradually settle to the bottom of the delivery pipe 22, while the relatively lighter and clearer supernatant is located at the top. When the leachate reaches the outlet of the delivery pipe 22 and enters the diversion pipe 6, due to the special layout and connection method of the upper pipe 61 and the lower pipe 62, based on gravity and the flow characteristics of the liquid itself , will naturally produce diversion. The relatively clear supernatant located at the upper part of the delivery pipe 22 will preferentially flow into the upper pipe 61 under the influence of gravity and the liquid flow direction and pressure distribution at the outlet of the delivery pipe 22. The sediment located at the bottom of the delivery pipe 22 will flow into the lower pipe 62 under the action of gravity because it is heavier and close to the inlet of the lower pipe 62. Through this working principle of the diversion pipe 6, the preliminary separation and reasonable diversion of the leachate after ultraviolet treatment are achieved, thereby improving the treatment efficiency of the entire leachate treatment station and the operating stability of the membrane treatment module 3.

[0059] In order to adjust the opening size of the upper tube 61 and the lower tube 62 according to the amount of sediment, please refer to Figure 5 In a preferred embodiment, an adjustment plate 63 is rotatably connected to the inlet of the upper tube 61 and the lower tube 62, and a driving assembly 64 is provided on the conveying pipe 22. The driving assembly 64 is used to drive the adjustment plate 63 to rotate, thereby adjusting the opening size of the upper tube 61 and the lower tube 62.

[0060] When in use, the adjusting plate 63 is located at the inlet of the upper tube 61 and the lower tube 62 and is rotatably connected thereto. This rotational movement can change the opening size of the inlet of the upper tube 61 and the lower tube 62. The driving assembly 64 is installed on the conveying pipe 22. Its main purpose is to provide power for the adjusting plate 63 so that the adjusting plate 63 can rotate. The initial state of the adjusting plate 63 is at a certain angle to the inlet of the upper tube 61 and the lower tube 62, so that the inlet has an initial opening size. When the driving assembly 64 drives the adjusting plate 63 to rotate in one direction, the adjusting plate 63 will gradually block the inlet of the upper tube 61 and the lower tube 62, thereby making the opening smaller. On the contrary, when the driving assembly 64 drives the adjusting plate 63 to rotate in another direction, the adjusting plate 63 will gradually move away from the originally blocked part of the inlet of the upper tube 61 and the lower tube 62, thereby making the opening larger. In this way, the opening size of the upper tube 61 and the lower tube 62 can be accurately adjusted according to actual work needs to control the material flow or other fluid flow through the pipeline.

[0061] To drive the adjustment plate 63 to rotate, please refer to Figure 5 In a preferred embodiment, the driving assembly 64 includes a motor disposed on the conveying pipe 22 , the output shaft of the motor penetrates into the conveying pipe 22 , and the output shaft of the motor is connected to the adjustment plate 63 .

[0062] When in use, the motor is installed on the conveying pipe 22 as a power source. The output shaft of the motor penetrates into the conveying pipe 22 and is connected to the adjustment plate 63. In this way, the rotational movement of the motor output shaft is directly transmitted to the adjustment plate 63. Since the adjustment plate 63 is rotatably connected to the inlet of the upper tube 61 and the lower tube 62, the adjustment plate 63 can rotate around its connection point with the inlet under the drive of the motor output shaft. When the motor rotates forward, the motor output shaft drives the adjustment plate 63 to rotate in one direction. Conversely, when the motor rotates reversely, the motor output shaft drives the adjustment plate 63 to rotate in the opposite direction.

[0063] The implementation principle of a leachate treatment station for a domestic waste incineration power plant in an embodiment of the present invention is as follows: the collection tank 11 is the core part of the collection module 1, and its main function is to collect the leachate generated from the domestic waste incineration power plant, providing a centralized source for the subsequent treatment of the leachate, ensuring that all leachate that needs to be treated can be effectively collected, and the pump body 21 starts working, and uses its own suction capacity to suck the leachate in the collection tank 11 from the outlet of the collection tank 11 to the inlet of the pump body 21, and then through the pressurization of the pump body 21, the leachate is pumped out from the outlet of the pump body 21. The ultraviolet lamp 23 extending along the length direction of the delivery pipe 22 is turned on at the same time and emits ultraviolet rays, thereby killing and inhibiting the microorganisms in the leachate, thereby achieving the purpose of preliminary purification of the leachate. The leachate treated by the ultraviolet treatment module 2 flows out from the outlet of the delivery pipe 22, and then enters the inlet of the membrane treatment module 3, thereby achieving fine treatment of the leachate and obtaining treated water that meets the discharge standards or reuse requirements.

[0064] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
