Description

Technical Field

[0001] This application relates to the technical field of water treatment, and in particular to a high-concentration wastewater treatment device. Background Technology

[0002] With the acceleration of industrialization, the discharge of industrial wastewater is constantly increasing. Among them, high-concentration organic wastewater has become one of the problems that urgently needs to be solved in the field of environmental protection due to its complex composition and serious pollution.

[0003] In recent years, membrane separation, biological treatment, and chemical oxidation technologies have been widely applied and developed, demonstrating good treatment effects under specific conditions. While these methods can improve water quality and reduce water pollution to some extent, they generally suffer from low removal rates and incomplete sterilization when dealing with high-concentration wastewater with complex components, particularly in handling recalcitrant organic matter. Therefore, there is an urgent need for treatment equipment suitable for high-concentration wastewater to improve treatment efficiency and reduce environmental pollution. Summary of the Invention

[0004] To improve the treatment effect of high-concentration wastewater, this application provides a high-concentration wastewater treatment device.

[0005] The high-concentration wastewater treatment equipment provided in this application adopts the following technical solution: A high-concentration wastewater treatment device includes an evaporation chamber and an oxidation chamber, connected by a connecting pipe, which allows the evaporation chamber and oxidation chamber to communicate with each other. The evaporation chamber is equipped with a heating element for heating the wastewater, and the oxidation chamber is equipped with an isolation sleeve containing an ultraviolet lamp. The oxidation chamber is also equipped with a flow-slowing component to reduce the flow rate of steam within the oxidation chamber.

[0006] By adopting the above technical solution, wastewater is introduced into the evaporation chamber, where heating elements raise the temperature, causing the wastewater to evaporate and vaporize into waste steam. The waste steam is then discharged into the oxidation chamber through a connecting pipe, where it is slowed down by a flow-regulating component, facilitating gas-liquid separation. Ultraviolet lamps in the oxidation chamber irradiate the waste steam and separated liquid flowing through it, achieving a sterilization effect. The combination of the evaporation and oxidation chambers significantly improves the degradation and treatment capacity of organic matter in the wastewater, thereby enhancing the treatment effect on high-concentration wastewater and reducing environmental pollution.

[0007] Optionally, the flow-retarding assembly includes a first flow-retarding plate and a second flow-retarding plate. Multiple first flow-retarding plates and multiple second flow-retarding plates are spaced apart along the length of the isolation sleeve, and the multiple first flow-retarding plates and multiple second flow-retarding plates are arranged in an alternating manner. A first flow-through port is formed between the inner peripheral wall of the first flow-retarding plate and the outer peripheral wall of the isolation sleeve, and a second flow-through port is formed between the outer peripheral wall of the second flow-retarding plate and the inner peripheral wall of the oxidation chamber.

[0008] By adopting the above technical solution, multiple first flow-damping plates and multiple second flow-damping plates are arranged in an alternating manner to create a misalignment between the first flow port and the adjacent second flow port, thereby greatly improving the flow path of waste steam, extending the residence time of waste steam in the oxidation chamber, and thus improving the sterilization effect of ultraviolet lamps.

[0009] Optionally, the first flow-retarding plate is disposed on the inner peripheral wall of the oxidation chamber, and the height of the first flow-retarding plate gradually decreases from the outer peripheral side towards the first flow port, and a first flow-retarding zone is formed between the lower surface of the first flow-retarding plate and the inner peripheral wall of the oxidation chamber.

[0010] By adopting the above technical solution, the height of the first flow-retarding plate gradually decreases from the outer periphery towards the first flow port, allowing the separated liquid to flow down the surface of the first flow-retarding plate, enabling the ultraviolet lamp to fully irradiate the liquid flowing through the first flow port. After entering the first flow-retarding zone, the waste steam impacts the inner wall of the zone, creating a significant deceleration effect and improving the gas-liquid separation efficiency.

[0011] Optionally, the second flow-retarding plate is disposed on the outer peripheral wall of the isolation sleeve, and the height of the second flow-retarding plate gradually increases from the inner peripheral side to the second flow port, and a second flow-retarding zone is formed between the upper surface of the second flow-retarding plate and the outer peripheral wall of the isolation sleeve.

[0012] By adopting the above technical solution, the second slow-flow plate gradually increases in height from the inner circumference towards the second flow outlet, thus forming a second slow-flow zone. The advantages of this design are: First, after the waste steam enters the second slow-flow zone, it impacts the inner wall of the zone, creating a deceleration effect and improving the gas-liquid separation efficiency. Second, the second slow-flow zone can collect the downstream liquid, increasing the residence time of the liquid on the outside of the isolation sleeve, providing sufficient irradiation time for the ultraviolet lamp, thereby improving the wastewater treatment effect. Third, the temperature difference between the liquid retained in the second slow-flow zone and the waste steam allows for heat exchange with the flowing waste steam to a certain extent, further improving the gas-liquid separation effect.

[0013] Optionally, the inner peripheral wall of the second flow-slowing plate is provided with multiple water inlets, which are arranged at intervals around the central axis of the isolation sleeve; a cover plate for opening and closing the water inlets is slidably installed on the upper surface of the second flow-slowing plate, and a return spring is provided between the cover plate and the second flow-slowing plate. Under normal conditions, the return spring forces the cover plate to cover the water inlets; the cover plate is connected to a buoyancy block.

[0014] By adopting the above technical solution, after a certain amount of liquid is collected in the second slow-flow zone, as the liquid level rises, the buoyancy block pulls the cover plate, forcing it to open the permeable outlet to discharge the liquid downwards in a timely manner. After the liquid is discharged, the water level drops, and the cover plate closes the permeable outlet again, allowing the second slow-flow zone to collect liquid again. The achieved effect is to promptly replace the liquid in the second slow-flow zone, reducing the possibility of scale formation on the outer wall of the isolation sleeve due to prolonged stagnation of liquid in the second slow-flow zone, thereby ensuring the irradiation effect of the ultraviolet lamps.

[0015] Optionally, each of the second flow-retarding plates is rotatably mounted on the outer peripheral wall of the isolation sleeve, and a first connecting rod is connected between two adjacent second flow-retarding plates. The first connecting rod is provided with a scraper that abuts against the outer peripheral wall of the isolation sleeve. The oxidation chamber is provided with a drive assembly for driving the second flow-retarding plates to rotate.

[0016] By adopting the above technical solution, multiple second flow-damping plates are connected in series to form a whole via a first connecting rod. In actual operation, the second flow-damping plates can be rotated by a drive assembly, causing the first connecting rod to drive a scraper to scrape the outer peripheral wall of the isolation sleeve, reducing the adhesion of foreign matter to the outer peripheral wall of the isolation sleeve or the formation of scale, thereby ensuring the irradiation effect of the ultraviolet lamp. On the other hand, when the second flow-damping plate rotates around its own central axis, it can throw out the liquid collected in the second flow-damping zone, thereby reducing the possibility of liquid remaining in the second flow-damping zone for a long time.

[0017] Optionally, the drive assembly includes a rotating disk, a second connecting rod, and a drive component. The rotating disk is coaxially disposed on the top of the isolation sleeve and directly opposite the outlet end of the connecting pipe. One end of the second connecting rod is connected to the lower surface of the rotating disk, and the other end is connected to the uppermost second flow buffer plate. The drive component is disposed on the rotating disk to drive the rotating disk to rotate.

[0018] By adopting the above technical solution, the rotating disk is forced to rotate by the driving component, so that the rotating disk can drive the second flow damper to rotate through the second connecting rod, so that the scraper can scrape the isolation sleeve.

[0019] Optionally, the top of the oxidation chamber has a connecting chamber, and the outlet end of the connecting pipe communicates with the connecting chamber; the driving component includes a driving impeller, which is disposed in the connecting chamber and connected to the rotating disk.

[0020] By adopting the above technical solution, the wastewater, after being heated and evaporated in the evaporation chamber, is fed into the connecting chamber of the oxidation chamber through the connecting pipe. This process performs work on the drive impeller, thereby driving the rotating disk to rotate, allowing the scraper blades to scrape the outer peripheral wall of the isolation sleeve. Simultaneously, the waste steam, by performing work on the drive impeller, consumes some of its energy, which aids in gas-liquid separation.

[0021] Optionally, a pressurization chamber is provided between the evaporation chamber and the oxidation chamber. The connecting pipe includes a first connecting section and a second connecting section. The inlet end of the first connecting section is connected to the evaporation chamber, and the outlet end of the first connecting section is connected to the pressurization chamber. The inlet end of the second connecting section is connected to the pressurization chamber, and the outlet end of the second connecting section is connected to the connecting chamber. A pressurization component is provided in the pressurization chamber.

[0022] By adopting the above technical solution, the waste steam is pressurized by the pressurizing component in the pressurizing chamber before entering the connecting chamber, so that the waste steam can reach a certain pressure, thereby ensuring that the waste steam can drive the impeller to rotate after entering the connecting chamber, reducing the possibility that the waste steam pressure is insufficient and cannot drive the impeller to rotate.

[0023] Optionally, the pressurization assembly includes a fixed plate, a movable plate, and a compression spring. The fixed plate is fixedly installed on the inner wall of the pressurization chamber, and the fixed plate has multiple first vent holes on its surface. The movable plate is slidably installed on the inner wall of the pressurization chamber, and the movable plate has multiple second vent holes on its surface. All the first vent holes and all the second vent holes are arranged alternately. The compression spring is disposed between the movable plate and the inner wall of the pressurization chamber. Under normal conditions, the compression spring forces the surface of the movable plate to abut against the surface of the fixed plate.

[0024] By adopting the above technical solution, under normal conditions, the surface of the movable plate abuts against the surface of the fixed plate under the action of the compression spring. The contact between the fixed plate and the movable plate can cut off the pressurization chamber, preventing the waste steam generated in the steam chamber from being discharged. As waste steam continues to be generated in the evaporation chamber, once the waste steam reaches a certain pressure, it can overcome the elasticity of the compression spring and push the movable plate open, forcing the movable plate and the fixed plate to separate, thereby opening the pressurization chamber. This allows waste steam at a certain pressure in the evaporation chamber to flow to the connecting chamber, ensuring that the waste steam has sufficient power to drive the impeller to rotate.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating an evaporation chamber and an oxidation chamber, wastewater is introduced into the evaporation chamber, where heating elements raise its temperature, causing the wastewater to evaporate and vaporize into steam. The waste steam is then discharged to the oxidation chamber through a connecting pipe, where a flow-slowing component reduces its velocity, facilitating gas-liquid separation. Ultraviolet lamps within the oxidation chamber irradiate the waste steam and separated liquid, achieving a sterilization effect. This combination of evaporation and oxidation chambers significantly enhances the degradation capacity of organic matter in the wastewater, thereby improving the treatment efficiency for high-concentration wastewater and reducing environmental pollution. 2. By setting up a second flow-retarding plate, the height of the second flow-retarding plate gradually increases from the inner circumference towards the second flow outlet, thus forming a second flow-retarding zone. The advantages of this design are: First, after the waste steam enters the second flow-retarding zone, it impacts the inner wall of the zone, creating a deceleration effect and improving the gas-liquid separation efficiency. Second, the second flow-retarding zone can collect the downstream liquid, increasing the residence time of the liquid on the outside of the isolation sleeve, providing sufficient irradiation time for the ultraviolet lamp, thereby improving the wastewater treatment effect. Third, the temperature difference between the liquid retained in the second flow-retarding zone and the waste steam allows for heat exchange with the flowing waste steam to a certain extent, further improving the gas-liquid separation effect. 3. Through the configuration of the drive assembly, multiple second flow-damping plates are connected in series via a first connecting rod. In actual operation, the drive assembly can rotate the second flow-damping plates, causing the first connecting rod to drive the scraper to scrape the outer peripheral wall of the isolation sleeve, reducing the adhesion of foreign matter or scale buildup on the outer peripheral wall of the isolation sleeve, thereby ensuring the irradiation effect of the ultraviolet lamp. On the other hand, when the second flow-damping plates rotate around their central axis, they can throw out the liquid collected in the second flow-damping zone, thereby reducing the possibility of liquid remaining in the second flow-damping zone for a long time.

[0028] The following combination Figures 1-8 This application will be described in further detail.

[0029] Example 1: This application discloses a high-concentration wastewater treatment device.

[0030] Reference Figure 1 , Figure 2 A high-concentration wastewater treatment device includes an evaporation chamber 1 and an oxidation chamber 2. The evaporation chamber 1 is equipped with a heating element for heating the wastewater. In this embodiment, the heating element is a heating pipe 11 for conveying steam, which is arranged in a serpentine pattern within the evaporation chamber 1 (the serpentine arrangement of the heating pipe 11 within the evaporation chamber 1 is not shown in the figure). This design increases the contact area between the heating pipe 11 and the wastewater within the evaporation chamber 1.

[0031] The top of the oxidation chamber 2 has a connecting chamber 21, which is connected to the oxidation chamber 2. A connecting pipe 3 connects the evaporation chamber 1 and the oxidation chamber 2. In this embodiment, the inlet end of the connecting pipe 3 is connected to the evaporation chamber 1 and the inlet end of the connecting pipe 3 is located at the top of the evaporation chamber 1. The outlet end of the connecting pipe 3 is connected to the connecting chamber 21 of the oxidation chamber 2. The evaporation chamber 1 and the oxidation chamber 2 are connected to each other through the connecting pipe 3 so that the waste steam generated in the evaporation chamber 1 (waste water is heated and vaporized to form waste steam) can be transported to the oxidation chamber 2.

[0032] Reference Figure 2An oxidation chamber 2 contains a filter plate 22, which is horizontally oriented and has multiple filter holes 221. An isolation sleeve 4 is vertically oriented within the oxidation chamber 2, with its lower end fixedly connected to the upper surface of the filter plate 22. A sealing plug (not shown in the figure) is installed at the upper end of the isolation sleeve 4. In this embodiment, the isolation sleeve 4 is made of quartz glass.

[0033] An ultraviolet lamp is installed inside the isolation sleeve 4 (the ultraviolet lamp is used to generate ultraviolet light; ultraviolet lamps are existing technology, and their structure will not be described in detail here, nor is it shown in the figure). It should be noted that, depending on the organic matter components in the wastewater that need to be degraded, an oxidant (such as hydrogen peroxide, ozone, etc.) can be introduced into the oxidation chamber 2 during ultraviolet irradiation to enhance the oxidation effect of ultraviolet light and improve the degradation effect on organic matter in the wastewater.

[0034] Reference Figure 2 An easing component 5 is provided inside the oxidation chamber 2. The easing component 5 is used to slow down the flow rate of steam in the oxidation chamber 2 and improve the gas-liquid separation effect of steam. The easing component 5 includes a first easing plate 51 and a second easing plate 52. Both the first easing plate 51 and the second easing plate 52 are annular plates. Multiple first easing plates 51 and multiple second easing plates 52 are arranged at intervals along the length of the isolation sleeve 4, and the multiple first easing plates 51 and multiple second easing plates 52 are arranged in an alternating manner. A first flow port 511 is formed between the inner peripheral wall of the first easing plate 51 and the outer peripheral wall of the isolation sleeve 4, and a second flow port 521 is formed between the outer peripheral wall of the second easing plate 52 and the inner peripheral wall of the oxidation chamber 2.

[0035] It should be noted that in this embodiment, the number of ultraviolet lamps in the isolation sleeve 4 is set to be multiple. The multiple ultraviolet lamps are arranged at intervals along the height direction. The multiple ultraviolet lamps are correspondingly set with multiple first flow ports 511. Each ultraviolet lamp is directly opposite the corresponding first flow port 511 (that is, the first flow port 511 is in a ring around the outer periphery of the corresponding ultraviolet lamp).

[0036] Reference Figure 2 In this embodiment, the outer peripheral wall of the first flow-retarding plate 51 is fixedly installed on the inner peripheral wall of the oxidation chamber 2. The height of the first flow-retarding plate 51 gradually decreases from the outer peripheral side towards the first flow port 511, and a first flow-retarding zone 512 is formed between the lower surface of the first flow-retarding plate 51 and the inner peripheral wall of the oxidation chamber 2. The second flow-retarding plate 52 is sleeved on the outer peripheral wall of the isolation sleeve 4. The inner peripheral wall of the second flow-retarding plate 52 is in contact with the outer peripheral wall of the isolation sleeve 4. The height of the second flow-retarding plate 52 gradually increases from the inner peripheral side towards the second flow port 521, and a second flow-retarding zone 522 is formed between the upper surface of the second flow-retarding plate 52 and the outer peripheral wall of the isolation sleeve 4.

[0037] Multiple first connecting rods 6 connect adjacent second flow buffer plates 52, and the two adjacent second flow buffer plates 52 are connected in series to form a whole through the first connecting rods 6; multiple third connecting rods 527 are installed on the lower surface of the bottom second flow buffer plate 52, and the third connecting rods 527 are vertically arranged. In this embodiment, the lower end of the third connecting rod 527 is fixedly connected to the upper surface of the filter plate 22, and the multiple second flow buffer plates 52 are mounted on the filter plate 22 through the third connecting rods 527.

[0038] The implementation principle of Embodiment 1 of this application is as follows: Wastewater is introduced into evaporation chamber 1, and the temperature is increased by heating elements, causing the wastewater to evaporate and vaporize into waste steam. The waste steam is discharged to oxidation chamber 2 through connecting pipe 3. Under the action of the first flow-retardant plate 51 and the second flow-retardant plate 52, the flow rate of the waste steam is significantly reduced, which helps gas-liquid separation. The ultraviolet lamps in oxidation chamber 2 can irradiate the waste steam and the separated liquid flowing through oxidation chamber 2 with ultraviolet light, achieving a sterilization effect. The combination of evaporation chamber 1 and oxidation chamber 2 greatly improves the degradation capacity of organic matter in wastewater, thereby improving the treatment effect of high-concentration wastewater and reducing the pollution caused by wastewater to the environment.

[0039] Furthermore, the second slow-flow plate 52 gradually increases in height from the inner circumference towards the second flow port 521, thus forming a second slow-flow zone 522. The advantages of this design are: First, after entering the second slow-flow zone 522, the waste steam impacts the inner wall of the zone, creating a deceleration effect and improving the gas-liquid separation efficiency. Second, the second slow-flow zone 522 can collect the downstream liquid, increasing the residence time of the liquid outside the isolation sleeve 4, providing sufficient irradiation time for the ultraviolet lamp, thereby improving the wastewater treatment effect. Third, the temperature difference between the liquid and waste steam retained in the second slow-flow zone 522 allows for heat exchange with the flowing waste steam to a certain extent, further improving the gas-liquid separation effect.

[0040] Example 2: This application discloses a high-concentration wastewater treatment device.

[0041] The difference between the high-concentration wastewater treatment device disclosed in this application and Embodiment 1 is that: Reference Figure 3In this embodiment, the inner peripheral wall of the second flow-slowing plate 52 is provided with a plurality of water inlets 523, which are arranged at intervals around the central axis of the isolation sleeve 4. The plurality of water inlets 523 and the plurality of first connecting rods 6 are staggered around the central axis of the isolation sleeve 4. A cover plate 524 is installed at each water inlet 523. The cover plate 524 is slidably installed on the upper surface of the second flow-slowing plate 52. A return spring 525 is installed between the cover plate 524 and the second flow-slowing plate 52. One end of the return spring 525 is fixedly connected to the second flow-slowing plate 52, and the other end is fixedly connected to the side wall of the cover plate 524. Under normal conditions, the return spring 525 forces the cover plate 524 to cover the water inlet 523.

[0042] A pull rope 528 is connected to the side wall of the cover plate 524, and a buoyancy block 526 is fixedly connected to the end of the pull rope 528 away from the cover plate 524. The buoyancy block 526 can be made of inorganic foam material (such as foam ceramic, foam glass, etc.) to provide stable buoyancy in high-temperature environments.

[0043] The implementation principle of Embodiment 2 of this application is as follows: After a certain amount of liquid is collected in the second slow-flow zone 522, as the liquid level in the second slow-flow zone 522 rises, the buoyancy block 526 can pull the cover plate 524, forcing the cover plate 524 to open the water inlet 523 to discharge the liquid downwards in a timely manner. After the liquid is discharged, the water level drops, and the cover plate 524 closes the water inlet 523 again, so that the second slow-flow zone 522 can collect liquid again. The effect achieved is that the liquid in the second slow-flow zone 522 can be replaced in a timely manner, reducing the possibility that the liquid will remain in the second slow-flow zone 522 for a long time without being replaced in time, resulting in scale formation on the outer peripheral wall of the isolation sleeve 4, thereby ensuring the irradiation effect of the ultraviolet lamp.

[0044] Example 3: This application discloses a high-concentration wastewater treatment device.

[0045] The difference between the high-concentration wastewater treatment device disclosed in this application and Embodiment 1 is that: Reference Figure 4 , Figure 5 In this embodiment, the filter plate 22 is provided with a rotating ring 222, which is rotatably mounted on the upper surface of the filter plate 22 and coaxially arranged with the isolation sleeve 4. The lower ends of all the third connecting rods 527 are fixedly mounted on the rotating ring 222, so that all the second flow-damping plates 52 are rotatably mounted on the outer peripheral wall of the isolation sleeve 4. Each first connecting rod 6 is equipped with a connecting frame 62, and a scraper 61 is fixedly mounted on the side wall of the connecting frame 62 away from the first connecting rod 6. The scraper 61 abuts against the outer peripheral wall of the isolation sleeve 4.

[0046] The oxidation chamber 2 is equipped with a drive assembly 7 for driving the second buffer plate 52 to rotate. The drive assembly 7 includes a rotating disk 71, a second connecting rod 72 and a drive component. The rotating disk 71 is coaxially disposed on the top of the isolation sleeve 4 and directly opposite the connecting chamber 21 (i.e., the rotating disk 71 is directly opposite the outlet end of the connecting pipe 3). Multiple second connecting rods 72 are provided, and the upper ends of the multiple second connecting rods 72 are fixedly connected to the lower surface of the rotating disk 71. The lower ends of the second connecting rods 72 are fixedly connected to the uppermost second buffer plate 52.

[0047] The rotating disk 71 has a circular plate-like structure. The height of the rotating disk 71 gradually decreases from the center to the periphery. A rotating shaft 711 is coaxially fixed on the upper surface of the rotating disk 71, and the upper end of the rotating shaft 711 extends into the connecting chamber 21. A driving component is disposed on the rotating disk 71 to drive the rotating disk 71 to rotate. In this embodiment, the driving component is a drive motor (not shown in the figure). The drive motor is fixedly installed on the top wall of the connecting chamber 21, and the output shaft of the drive motor extends into the connecting chamber 21 and is coaxially connected to the rotating shaft 711.

[0048] The implementation principle of Embodiment 3 of this application is as follows: When it is necessary to clean foreign objects (such as scale) from the outer peripheral wall of the isolation sleeve 4, the drive motor drives the rotating disk 71 to rotate, causing the first connecting rod 6 to drive the scraper 61 to scrape the outer peripheral wall of the isolation sleeve 4, reducing the possibility of foreign objects adhering to the outer peripheral wall of the isolation sleeve 4, thereby ensuring the irradiation effect of the ultraviolet lamp. On the other hand, when the rotating disk 71 drives the second flow-retarding plate 52 to rotate around its own central axis, it can throw out the liquid collected in the second flow-retarding zone 522, thereby reducing the possibility of liquid remaining in the second flow-retarding zone 522 for a long time.

[0049] Example 4: This application discloses a high-concentration wastewater treatment device.

[0050] The difference between the high-concentration wastewater treatment device disclosed in this application and Embodiment 3 is that: Reference Figure 6 , Figure 7 , Figure 8 In this embodiment, the driving component is configured as a driving impeller 73, which is installed on the inner wall of the connecting chamber 21. The rotating shaft 711 of the rotating disk 71 is connected to the driving impeller 73. A pressurizing chamber 8 is provided between the evaporation chamber 1 and the oxidation chamber 2. The connecting pipe 3 includes a first connecting section 31 and a second connecting section 32. The inlet end of the first connecting section 31 is connected to the evaporation chamber 1, and the outlet end of the first connecting section 31 is connected to the pressurizing chamber 8. The inlet end of the second connecting section 32 is connected to the pressurizing chamber 8, and the outlet end of the second connecting section 32 is connected to the connecting chamber 21.

[0051] A pressurizing assembly 9 is provided inside the pressurizing chamber 8. In this embodiment, the pressurizing assembly 9 includes a fixed plate 91, a movable plate 92, and a compression spring 93. The fixed plate 91 is fixedly installed on the inner wall of the pressurizing chamber 8. The fixed plate 91 has a plurality of first vent holes 911 on its surface. The movable plate 92 is slidably installed on the inner wall of the pressurizing chamber 8, and the movable plate 92 is located on the side of the fixed plate 91 near the second connecting section 32. The movable plate 92 has a plurality of second vent holes 921 on its surface. All the first vent holes 911 and all the second vent holes 921 are arranged in an alternating pattern.

[0052] One end of the compression spring 93 is fixedly connected to the movable plate 92, and the other end is fixedly connected to the inner wall of the pressure chamber 8. Under normal conditions, the compression spring 93 forces the surface of the movable plate 92 to abut against the surface of the fixed plate 91 to cut off the pressure chamber 8.

[0053] Reference Figure 8 A switching pipe 33 connects the first connecting section 31 and the second connecting section 32. The inlet end of the switching pipe 33 is connected to the first connecting section 31, and the outlet end of the switching pipe 33 is connected to the second connecting section 32. A first valve 34 is installed on the first connecting section 31, and a second valve 35 is installed on the switching pipe 33. The first valve 34 and the second valve 35 can be pneumatic valves. The pressurization chamber 8 is connected to an vent pipe 81, and the inlet end of the vent pipe 81 is located on the side of the fixed plate 91 away from the movable plate 92.

[0054] The implementation principle of Embodiment 4 of this application is as follows: When it is not necessary to scrape foreign objects off the outer peripheral wall of the isolation sleeve 4, the second valve 35 is opened and the first valve 34 is closed, so that the steam in the evaporation chamber 1 is discharged to the oxidation chamber 2 in sequence through the first connecting section 31, the switching pipe 33, and the second connecting section 32; when it is necessary to scrape foreign objects off the outer peripheral wall of the isolation sleeve 4, the second valve 35 is closed and the first valve 34 is opened, so that the steam can enter the pressurization chamber 8 for pressurization, ensuring that the steam entering the connecting chamber 21 has sufficient power to drive the drive impeller 73 to rotate, reducing the possibility that the waste steam pressure is insufficient and cannot drive the drive impeller 73 to rotate.

[0055] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
