Description

Technical Field

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

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

[0003] In recent years, technologies such as membrane separation, biological treatment, and chemical oxidation have been widely applied and developed, and these technologies show good treatment effects under specific conditions. Although the above methods can improve water quality and reduce water pollution to a certain extent, when facing high-concentration wastewater with complex components, there are generally problems such as low removal rate and incomplete sterilization effect, especially poor performance in dealing with refractory organic compounds. Therefore, there is an urgent need for a treatment device suitable for high-concentration wastewater to improve the treatment effect of wastewater and reduce the pollution to the environment. Summary of the Invention

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

[0005] The high-concentration wastewater treatment device provided by this application adopts the following technical solutions: A high-concentration wastewater treatment device includes an evaporation chamber and an oxidation chamber. A connecting pipe is connected between the evaporation chamber and the oxidation chamber, and the evaporation chamber and the oxidation chamber are interconnected through the connecting pipe. A heating member for heating wastewater is provided in the evaporation chamber, an isolation sleeve is arranged in the oxidation chamber, and an ultraviolet lamp is installed in the isolation sleeve. A flow-slowing component is arranged in the oxidation chamber, and the flow-slowing component is used to slow down the flow rate of the steam in the oxidation chamber.

[0006] By adopting the above technical solutions, the wastewater is introduced into the evaporation chamber, and the temperature is increased by the heating member to evaporate and vaporize the wastewater to form waste steam. The waste steam is discharged to the oxidation chamber through the connecting pipe and decelerates under the action of the flow-slowing component, which helps with gas-liquid separation. The ultraviolet lamp in the oxidation chamber can perform ultraviolet irradiation on the waste steam flowing through the oxidation chamber and the separated liquid, achieving a sterilization effect. The combination of the evaporation chamber and the oxidation chamber greatly improves the degradation treatment ability of the organic matter in the wastewater, thereby improving the treatment effect of high-concentration wastewater and reducing the pollution of the wastewater to the environment.

[0007] Optionally, the flow buffering component includes a first flow buffering plate and a second flow buffering plate. A plurality of first flow buffering plates and a plurality of second flow buffering plates are both arranged at intervals along the length direction of the isolation sleeve, and the plurality of first flow buffering plates and the plurality of second flow buffering plates are arranged in a staggered manner; a first flow passage is formed between the inner peripheral wall of the first flow buffering plate and the outer peripheral wall of the isolation sleeve, and a second flow passage is formed between the outer peripheral wall of the second flow buffering plate and the inner peripheral wall of the oxidation chamber.

[0008] By adopting the above technical solution, the plurality of first flow buffering plates and the plurality of second flow buffering plates are arranged in a staggered manner, so that a dislocation is formed between the first flow passage and the adjacent second flow passage, greatly increasing the flow path of the waste steam, prolonging the residence time of the waste steam in the oxidation chamber, and thus improving the sterilization treatment effect of the ultraviolet lamp on it.

[0009] Optionally, the first flow buffering plate is arranged on the inner peripheral wall of the oxidation chamber. The height of the first flow buffering plate gradually decreases from the outer peripheral side to the first flow passage, and a first flow buffering area is formed between the lower surface of the first flow buffering plate and the inner peripheral wall of the oxidation chamber.

[0010] By adopting the above technical solution, the height of the first flow buffering plate gradually decreases from the outer peripheral side to the first flow passage, so that the separated liquid can flow down along the surface of the first flow buffering plate, enabling the ultraviolet lamp to fully irradiate the liquid flowing through the first flow passage. After the waste steam enters the first flow buffering area, it collides with the inner wall of the first flow buffering area to form a significant deceleration effect, improving the gas-liquid separation effect.

[0011] Optionally, the second flow buffering plate is arranged on the outer peripheral wall of the isolation sleeve. The height of the second flow buffering plate gradually increases from the inner peripheral side to the second flow passage, and a second flow buffering area is formed between the upper surface of the second flow buffering plate and the outer peripheral wall of the isolation sleeve.

[0012] By adopting the above technical solution, the height of the second flow buffering plate gradually increases from the inner peripheral side to the second flow passage, thus forming a second flow buffering area. The advantages of such a design are as follows: Firstly, after the waste steam enters the second flow buffering area, it collides with the inner wall of the second flow buffering area to form a deceleration effect, improving the gas-liquid separation effect. Secondly, the second flow buffering area can collect the flowing-down liquid, increasing the residence time of the liquid outside the isolation sleeve, providing sufficient irradiation time for the ultraviolet lamp, and thus improving the treatment effect on the wastewater. Thirdly, a temperature difference is formed between the liquid retained in the second flow buffering area and the waste steam, which can exchange heat with the flowing waste steam to a certain extent, further improving the gas-liquid separation effect.

[0013] Optionally, a plurality of water permeable openings are formed in the inner peripheral wall of the second slow flow plate, and the plurality of water permeable openings are arranged at intervals around the central axis of the isolation sleeve; a cover plate for opening and closing the water permeable openings is slidably mounted on the upper surface of the second slow flow plate, a return spring is arranged between the cover plate and the second slow flow plate, and under normal conditions, the return spring forces the cover plate to cover the water permeable openings; the cover plate is connected with a buoyancy block.

[0014] By adopting the above technical solution, after a certain amount of liquid is collected in the second slow flow area, as the liquid level in the second slow flow area rises, the buoyancy block can pull the cover plate to force the cover plate to open the water permeable opening, so as to timely discharge the liquid downward. After the liquid is discharged, the water level drops, and the cover plate closes the water permeable opening again, so that the second slow flow area can collect the liquid again. The achieved effect is that the liquid in the second slow flow area can be replaced in time, reducing the possibility that the liquid stays in the second slow flow area for a long time without being replaced in time, resulting in the generation of scale on the outer peripheral wall of the isolation sleeve, and thus ensuring the irradiation effect of the ultraviolet lamp.

[0015] Optionally, each of the second slow flow plates is rotatably mounted on the outer peripheral wall of the isolation sleeve, a first connecting rod is connected between two adjacent second slow flow plates, and a scraping strip abutted against the outer peripheral wall of the isolation sleeve is arranged on the first connecting rod; a driving assembly for driving the second slow flow plate to rotate is arranged in the oxidation chamber.

[0016] By adopting the above technical solution, a plurality of second slow flow plates are connected in series as a whole through the first connecting rod. In actual operation, the driving assembly can drive the second slow flow plate to rotate, so that the first connecting rod drives the scraping strip to scrape the outer peripheral wall of the isolation sleeve, reducing the attachment of foreign matters to the outer peripheral wall of the isolation sleeve or the generation of scale, and thus ensuring the irradiation effect of the ultraviolet lamp. On the other hand, when the second slow flow plate rotates around its own central axis, the liquid collected in the second slow flow area can be thrown out, thereby reducing the possibility that the liquid stays in the second slow flow area for a long time.

[0017] Optionally, the driving assembly includes a rotating disk, a second connecting rod and a driving member. The rotating disk is coaxially arranged at the top of the isolation sleeve and faces 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 slow flow plate; the driving member is arranged on the rotating disk for driving the rotating disk to rotate.

[0018] By adopting the above technical solution, the driving member forces the rotating disk to rotate, so that the rotating disk can drive the second slow flow plate to rotate through the second connecting rod, so as to realize that the scraping strip can scrape the isolation sleeve.

[0019] Optionally, a connection chamber is provided at the top of the oxidation chamber, and the outlet end of the connecting pipe communicates with the connection chamber; the driving member includes a driving impeller, and the driving impeller is arranged in the connection chamber and connected to the rotating disk.

[0020] By adopting the above technical solution, after the wastewater is heated and evaporated in the evaporation chamber, it is input into the connection chamber of the oxidation chamber through the connecting pipe, which can do work on the driving impeller, thereby driving the rotating disk to rotate, so that the scraping strip can scrape the outer peripheral wall of the isolation sleeve. At the same time, after the waste steam does work on the driving impeller, part of the energy of the waste steam is consumed, which helps the gas-liquid separation.

[0021] Optionally, a pressurizing 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 communicates with the evaporation chamber, and the outlet end of the first connecting section communicates with the pressurizing chamber; the inlet end of the second connecting section communicates with the pressurizing chamber, and the outlet end of the second connecting section communicates with the connection chamber, and a pressurizing component is provided in the pressurizing chamber.

[0022] By adopting the above technical solution, before the waste steam enters the connection chamber, it is pressurized by the pressurizing component in the pressurizing chamber, so that the waste steam can reach a certain pressure. Furthermore, after the waste steam enters the connection chamber, it can drive the driving impeller to rotate, reducing the possibility that the waste steam pressure is insufficient to drive the driving impeller to rotate.

[0023] Optionally, the pressurizing component includes a fixing plate, a movable plate and a compression spring. The fixing plate is fixedly installed on the inner wall of the pressurizing chamber. A plurality of first ventilation holes are formed on the plate surface of the fixing plate. The movable plate is slidably installed on the inner wall of the pressurizing chamber. A plurality of second ventilation holes are formed on the plate surface of the movable plate. All the first ventilation holes and all the second ventilation holes are arranged in an alternating manner; the compression spring is arranged between the movable plate and the inner wall of the pressurizing chamber. Under normal conditions, the compression spring forces the plate surface of the movable plate to abut against the plate surface of the fixing plate.

[0024] By adopting the above technical solution, under normal conditions, under the action of the compression spring, the plate surface of the movable plate abuts against the plate surface of the fixing plate. The fitting of the fixing plate and the movable plate can cut off the pressurizing chamber, so that the waste steam generated in the steam chamber cannot be discharged. As the waste steam in the evaporation chamber continues to be generated, after the waste steam reaches a certain pressure, it can overcome the elastic force of the compression spring and push open the movable plate, forcing the movable plate and the fixing plate to separate, thereby opening the pressurizing chamber, so that the waste steam with a certain air pressure in the evaporation chamber can flow to the connection chamber to ensure that the waste steam has enough power to drive the driving impeller to rotate.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the installation of an evaporation chamber and an oxidation chamber, wastewater is introduced into the evaporation chamber, where the temperature is increased by a heating element, causing the wastewater to evaporate and vaporize to form steam. The waste steam is discharged to the oxidation chamber through a connecting pipe, where it is decelerated by the slow-flow component, facilitating gas-liquid separation. The ultraviolet lamp in the oxidation chamber can irradiate the waste steam and separated liquid passing through the oxidation chamber with ultraviolet light, achieving a sterilization effect. The combination of the evaporation chamber and the oxidation chamber greatly improves the degradation capacity of organic matter in the wastewater, thereby improving the treatment effect of high-concentration wastewater and reducing the pollution caused by wastewater to the environment. 2. Through the setting of the second slow flow plate, the height of the second slow flow plate gradually increases from the inner circumference to the second flow port, thereby forming a second slow flow area. The advantages of such a design are: First, after the waste steam enters the second slow flow area, it collides with the inner wall of the second slow flow area to form a deceleration effect, thereby improving the gas-liquid separation effect. Second, the second slow flow area can collect the downstream liquid, increase the retention time of the liquid on the outside of the isolation sleeve, provide sufficient irradiation time for the ultraviolet lamp, and thus improve the treatment effect of the wastewater. Third, a temperature difference is formed between the liquid retained in the second slow flow area and the waste steam, which can exchange heat with the waste steam flowing through to a certain extent, further improving the gas-liquid separation effect; 3. Through the configuration of the drive assembly, multiple second slow-flow plates are connected in series via a first connecting rod to form an integral whole. In actual operation, the drive assembly can drive the second slow-flow plates to rotate, allowing the first connecting rod to drive the scraper to scrape the outer peripheral wall of the isolation sleeve, reducing the adhesion of foreign matter and the formation of scale on the outer peripheral wall of the isolation sleeve, thereby ensuring the irradiation effect of the UV lamp. Furthermore, when the second slow-flow plates rotate about their own central axis, they can expel liquid collected in the second slow-flow area, thereby reducing the possibility of liquid being retained in the second slow-flow area for a long time.

[0028] The following Figures 1-8 further describes the present application in detail.

[0029] Embodiment 1: An embodiment of the present application discloses a high-concentration wastewater treatment device.

[0030] Referring to Figure 1 , Figure 2 , a high-concentration wastewater treatment device includes an evaporation chamber 1 and an oxidation chamber 2. A heating member for heating wastewater is arranged in the evaporation chamber 1. In this embodiment, the heating member is set as a heating tube 11 for conveying steam, and the heating tube 11 is arranged in a serpentine shape in the evaporation chamber 1 (the serpentine arrangement of the heating tube 1 in the evaporation chamber 1 is not shown in the figure). Designed in this way to increase the contact area between the heating tube 11 and the wastewater in the evaporation chamber 1.

[0031] The top of the oxidation chamber 2 has a connection chamber 21, and the connection chamber 21 is communicated with the oxidation chamber 2; a connecting pipe 3 is connected between the evaporation chamber 1 and the oxidation chamber 2. In this embodiment, the inlet end of the connecting pipe 3 is communicated with 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 communicated with the connection chamber 21 of the oxidation chamber 2. The evaporation chamber 1 and the oxidation chamber 2 are interconnected through the connecting pipe 3, so that the waste steam generated in the evaporation chamber 1 (the wastewater is heated and vaporized to form waste steam) can be conveyed to the oxidation chamber 2.

[0032] Referring to Figure 2, a filter plate 22 is installed in the oxidation chamber 2. The plate surface of the filter plate 22 is horizontally arranged, and a plurality of filter holes 221 are formed in the plate surface of the filter plate 22; an isolation sleeve 4 is arranged in the oxidation chamber 2. The isolation sleeve 4 is vertically arranged. The lower end of the isolation sleeve 4 is fixedly connected to the upper surface of the filter plate 22, and 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 (the ultraviolet lamp is used to generate ultraviolet rays. The ultraviolet lamp is a prior art, and its structure will not be elaborated too much here and is not shown in the figure) is installed in the isolation sleeve 4. It should be noted that according to the components of the organic matter to be degraded in the wastewater, when performing ultraviolet irradiation, an oxidant (such as hydrogen peroxide, ozone, etc.) can be introduced into the oxidation chamber 2 to enhance the oxidation effect of the ultraviolet rays and improve the degradation effect of the organic matter in the wastewater.

[0034] Refer to Figure 2 , a flow retardation assembly 5 is arranged in the oxidation chamber 2. The flow retardation assembly 5 is used to slow down the flow rate of the steam in the oxidation chamber 2 and improve the gas-liquid separation effect of the steam; the flow retardation assembly 5 includes a first flow retardation plate 51 and a second flow retardation plate 52. Both the first flow retardation plate 51 and the second flow retardation plate 52 are annular plates. A plurality of first flow retardation plates 51 and a plurality of second flow retardation plates 52 are both arranged at intervals along the length direction of the isolation sleeve 4, and a plurality of first flow retardation plates 51 and a plurality of second flow retardation plates 52 are arranged in a staggered manner; a first flow passage 511 is formed between the inner peripheral wall of the first flow retardation plate 51 and the outer peripheral wall of the isolation sleeve 4, and a second flow passage 521 is formed between the outer peripheral wall of the second flow retardation plate 52 and the inner peripheral wall of the oxidation chamber 2.

[0035] It should be noted that in this embodiment, a plurality of ultraviolet lamps are arranged in the isolation sleeve 4. The plurality of ultraviolet lamps are arranged at intervals in the height direction. The plurality of ultraviolet lamps are correspondingly arranged with the plurality of first flow passages 511, and each ultraviolet lamp is directly opposite to the corresponding first flow passage 511 (that is, the first flow passage 511 is annular around the outer peripheral side of the corresponding ultraviolet lamp).

[0036] Refer to Figure 2 , in this embodiment, the outer peripheral wall of the first flow retardation plate 51 is fixedly installed on the inner peripheral wall of the oxidation chamber 2. The height of the first flow retardation plate 51 gradually decreases from the outer periphery to the first flow passage 511. A first flow retardation area 512 is formed between the lower surface of the first flow retardation plate 51 and the inner peripheral wall of the oxidation chamber 2. The second flow retardation plate 52 is sleeved on the outer peripheral wall of the isolation sleeve 4. The inner peripheral wall of the second flow retardation plate 52 is attached to the outer peripheral wall of the isolation sleeve 4. The height of the second flow retardation plate 52 gradually increases from the inner periphery to the second flow passage 521. A second flow retardation area 522 is formed between the upper surface of the second flow retardation plate 52 and the outer peripheral wall of the isolation sleeve 4.

[0037] A plurality of first connecting rods 6 are connected between two adjacent second flow retarder plates 52, and two adjacent second flow retarder plates 52 are connected in series through the first connecting rods 6 to form an integral body; a plurality of third connecting rods 527 are installed on the lower surface of the lowermost second flow retarder plate 52, and the third connecting rods 527 are arranged vertically. In this embodiment, the lower ends of the third connecting rods 527 are fixedly connected to the upper surface of the filter plate 22, and the plurality of second flow retarder plates 52 are erected 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 the evaporation chamber 1, and the temperature is increased by the heating element to vaporize the wastewater to form waste steam; the waste steam is discharged to the oxidation chamber 2 through the connecting pipe 3. Under the action of the first flow retarder plate 51 and the second flow retarder plate 52, the flow rate of the waste steam is significantly reduced, which helps with gas-liquid separation. The ultraviolet lamps in the oxidation chamber 2 can irradiate the waste steam and the separated liquid flowing through the oxidation chamber 2 with ultraviolet light, achieving a sterilization effect. The combination of the evaporation chamber 1 and the oxidation chamber 2 greatly improves the degradation ability of organic matter in the wastewater, thereby improving the treatment effect on high-concentration wastewater and reducing the pollution caused by the wastewater to the environment.

[0039] In addition, the height of the second flow retarder plate 52 gradually increases from the inner peripheral side to the second communication port 521, thereby forming a second flow retardation area 522. The advantages of such a design are as follows: On the one hand, after the waste steam enters the second flow retardation area 522, it collides with the inner wall of the second flow retardation area 522 to form a deceleration effect, improving the gas-liquid separation effect. On the other hand, the second flow retardation area 522 can collect the flowing-down liquid, increasing the residence time of the liquid outside the isolation sleeve 4, providing sufficient irradiation time for the ultraviolet lamp, and thus improving the treatment effect on the wastewater. On the third hand, a temperature difference is formed between the liquid retained in the second flow retardation area 522 and the waste steam, which can exchange heat with the flowing waste steam to a certain extent, further improving the gas-liquid separation effect.

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

[0041] The difference between the high-concentration wastewater treatment device disclosed in the embodiment of this application and Embodiment 1 lies in: Refer to Figure 3, in this embodiment, a plurality of water permeable openings 523 are formed in the inner peripheral wall of the second slow flow plate 52, and the plurality of water permeable openings 523 are arranged at intervals around the central axis of the isolation sleeve 4; the plurality of water permeable openings 523 and the plurality of first connecting rods 6 are arranged in a staggered manner around the central axis of the isolation sleeve 4, and a cover plate 524 is installed at each water permeable opening 523. The cover plate 524 is slidably installed on the upper surface of the second slow flow plate 52, and a return spring 525 is installed between the cover plate 524 and the second slow flow plate 52. One end of the return spring 525 is fixedly connected to the second slow flow 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 permeable opening 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 materials (such as foam ceramics, foam glass, etc.) to provide stable buoyancy in a high-temperature environment.

[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 area 522, as the liquid level in the second slow flow area 522 rises, the buoyancy block 526 can pull the cover plate 524 to force the cover plate 524 to open the water permeable opening 523, so as to discharge the liquid downward in time. After the liquid is discharged, the water level drops, and the cover plate 524 closes the water permeable opening 523 again, so that the second slow flow area 522 can collect the liquid again. The achieved effect is that the liquid in the second slow flow area 522 can be replaced in time, reducing the possibility that the liquid stands in the second slow flow area 522 for a long time without being replaced in time, resulting in the generation of scale on the outer peripheral wall of the isolation sleeve 4, thereby ensuring the irradiation effect of the ultraviolet lamp.

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

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

[0046] Inside the oxidation chamber 2, there is a driving assembly 7 for driving the second flow retarder plate 52 to rotate. The driving assembly 7 includes a rotating disk 71, a second connecting rod 72, and a driving member. The rotating disk 71 is coaxially arranged at the top of the isolation sleeve 4 and is opposite to the connection chamber 21 (that is, the rotating disk 71 is opposite to the outlet end of the connecting pipe 3); there are multiple second connecting rods 72. The upper ends of the multiple second connecting rods 72 are fixedly connected to the lower surface of the rotating disk 71, and the lower end of the second connecting rod 72 is fixedly connected to the uppermost second flow retarder 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 connection chamber 21; the driving member is arranged on the rotating disk 71 to drive the rotating disk 71 to rotate. In this embodiment, the driving member is set as a driving motor (not shown in the figure). The driving motor is fixedly installed on the top wall of the connection chamber 21, and the output shaft of the driving motor extends into the connection 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 foreign matters (such as scale) on the outer peripheral wall of the isolation sleeve 4 need to be cleaned, the driving motor drives the rotating disk 71 to rotate, so that the first connecting rod 6 drives the scraping strip 61 to scrape the outer peripheral wall of the isolation sleeve 4, reducing the possibility of foreign matters adhering to the outer peripheral wall of the isolation sleeve 4, and thus ensuring the irradiation effect of the ultraviolet lamp. On the other hand, when the rotating disk 71 drives the second flow retarder plate 52 to rotate around its own central axis, the liquid collected in the second flow retardation area 522 can be thrown out, thereby reducing the possibility of the liquid staying in the second flow retardation area 522 for a long time.

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

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

[0051] A pressurizing assembly 9 is arranged in 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. A plurality of first ventilation holes 911 are formed in the plate surface of the fixed plate 91. The movable plate 92 is slidably installed on the inner wall of the pressurizing chamber 8, and the movable plate 92 is located on one side of the fixed plate 91 close to the second connecting section 32. A plurality of second ventilation holes 921 are formed in the plate surface of the movable plate 92. All the first ventilation holes 911 and all the second ventilation holes 921 are arranged in a staggered manner.

[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 pressurizing chamber 8. Under normal conditions, the compression spring 93 forces the plate surface of the movable plate 92 to abut against the plate surface of the fixed plate 91 to cut off the pressurizing chamber 8.

[0053] Refer to Figure 8 , a switching pipe 33 is connected between the first connecting section 31 and the second connecting section 32. The inlet end of the switching pipe 33 communicates with the first connecting section 31, and the outlet end of the switching pipe 33 communicates with 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 pressurizing chamber 8 is connected with an evacuation pipe 81, and the inlet end of the evacuation 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 matters on 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 sequentially discharged to the oxidation chamber 2 through the first connecting section 31, the switching pipe 33 and the second connecting section 32; When it is necessary to scrape foreign matters on 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 pressurizing chamber 8 for pressurization, ensuring that the steam entering the connecting chamber 21 has sufficient power to drive the driving impeller 73 to rotate, and reducing the possibility that the waste steam pressure is insufficient to drive the driving impeller 73 to rotate.

[0055] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
