Description

Technical Field

[0001] The present application relates to the technical field of wastewater treatment, and in particular to a device and method for treating wastewater containing high-salt organic matter and high-concentration unbearable odor. Background Art

[0002] With the improvement of modern industrial level, some industrial sectors will discharge a large amount of high-salt organic matter and high-concentration and unbearable odorous wastewater during industrial production. The direct discharge of these wastewaters will lead to environmental deterioration and salinization of the land, and even some substances in them will directly cause harm to the human body. Therefore, these wastewaters must be treated before they can be discharged, and some useful resources generated in the purification process must be recycled.

[0003] For example, a high-salt and high-organic chemical wastewater treatment device and a sewage treatment method thereof with publication number CN116477695A relate to the technical field of high-salt and high-organic chemical wastewater treatment devices and sewage treatment methods, including multiple evaporation units and multiple slurry pumps arranged in series, the output ends of the multiple slurry pumps are respectively connected to the lower end of the next evaporation unit by pipelines, the output end of the last slurry pump is connected to the crystallizer by pipeline, the two sides of the first evaporation unit are respectively connected to the external heat pump by pipelines, the other side of the multiple evaporation units and the other side of the condensation mechanism are connected to the water collecting pipe by pipelines, and a desalination water tank, a circulation pump and a vacuum generator are provided at one end of the water collecting pipe. The prior art adopts the principle of low-temperature evaporation to greatly reduce the energy consumption during application; through a neat input, multiple times of water is evaporated, and at the same time, the feed liquid is concentrated step by step from the first evaporation unit to the last evaporation unit to reach supersaturation, and crystallized and precipitated through the crystallizer, thereby achieving a more thorough solid-liquid separation; and the brine concentration of the prior art is not limited.

[0004] However, the above-mentioned prior art still has some defects when treating high-salt and high-organic chemical wastewater: 1. In the process of heating the high-salt organic wastewater in the above-mentioned patent application, since the stable heat source only exists in the air inlet pipe on the upper part of the evaporation heat exchange tube, the wastewater in the device cannot be effectively and evenly heated, resulting in low concentration efficiency of the wastewater in the device, thereby reducing the wastewater treatment efficiency.

[0005] In the above patent application, during the step-by-step concentration process of wastewater, due to the different saturations of various salts or organic matter in the wastewater, crystals may precipitate in one of the evaporation units, resulting in a waste of crystals. The precipitated crystals may also clog the pores of the device, further reducing the wastewater treatment efficiency.

DETAILED DESCRIPTION

[0048] The following is combined with Figures 1 to 11 This application is described in further detail.

[0049] The embodiments of the present application disclose a device and method for treating wastewater containing high-salt organic matter and high-concentration unbearable odor, which can ensure that the wastewater can be fully and evenly heated, and avoid uneven heating of the wastewater affecting the efficiency of wastewater treatment.

[0050] Embodiment 1:

[0051] Reference Figure 1 , Figure 2 and Figure 3 A device for treating wastewater containing high-salt organic matter and high-concentration unbearable odor comprises a cylinder shell 1, on which cylinder shell 1 is respectively provided with cylinder shell 2, cylinder shell 3 and cylinder shell 4 along its radial direction and toward its center, and a truncated cone cover 15 is installed on the top of cylinder shell 1.

[0052] A cavity 1 5 is provided between the cylindrical shell 1 and the cylindrical shell 2 2, a cavity 2 6 is provided between the cylindrical shell 2 2 and the cylindrical shell 3 3, a cavity 3 7 is provided between the cylindrical shell 3 3 and the cylindrical shell 4 4, a cavity 4 8 is provided inside the cylindrical shell 4 4, cavity 1 5 is connected to the bottom of cavity 3 7, and cavity 2 6 is connected to the bottom of cavity 4 8.

[0053] A plurality of scraping and brushing plates 61 are installed inside the cavity 2 6, and each scraping and brushing plate 61 is symmetrically installed with a spray pipe 62 along its length direction, which can spray toxic gas into the wastewater. A guide block 63 is provided at the bottom of the scraping and brushing plate 61, and the guide block 63 spirally descends along the inner wall of the cylinder shell 2 2 and the outer wall of the cylinder shell 3 3, and an annular groove 64 for passing wastewater is also provided on the guide block 63.

[0054] Among them, multiple circulating air pipes 51 extending along the axial direction of the cylinder shell 1 are arranged inside the cavity 1 5 and the cavity 3 7, and a circulating air pump 52 is arranged on the top of each circulating air pipe 51. Support blocks 53 for fixing the circulating air pipes 51 are installed inside the cavity 1 5 and the cavity 3 7. The outer wall of the cylinder shell 1 is provided with a water vapor pipe 11, a disinfectant pipe 12 and a waste water pipe 13, and each is equipped with a one-way valve. The water vapor pipe 11 is connected with the cavity 1 5, and the disinfectant pipe 12 and the waste water pipe 13 are connected with the cavity 2 6. The materials used to make the cylinder shell 2 2, the cylinder shell 3 3 and the cylinder shell 4 4 have good thermal conductivity. In the specific implementation process, water vapor is first introduced into the cavity 1 5 through the water vapor pipe 11. Since the bottom of the cavity 1 5 and the cavity 3 7 are connected, the water vapor can fill the cavity 1 5 and In cavity three 7, since the water vapor temperature at the top of cavity one 5 and cavity three 7 is higher than that at the bottom, in order to avoid uneven heating of the wastewater, the circulating air pump 52 is started. The circulating air pump 52 introduces the water vapor with high temperature at the top of cavity one 5 and cavity three 7 to the bottom through the circulating air pipe 51, thereby continuously circulating the water vapor to ensure that the water vapor temperature at various places in cavity one 5 and cavity three 7 can be kept consistent, so that the water vapor can evenly heat the wastewater; secondly, the wastewater is introduced into cavity two 6 through the wastewater pipe 13. Since the bottom of cavity two 6 and cavity four 8 are connected, the wastewater in cavity two 6 enters cavity four 8 through the bottom channel, and the wastewater liquid levels in the two are flush; finally, the disinfectant is introduced into cavity two 6 through the disinfectant pipe 12, mixed with the wastewater and subjected to a chemical reaction.

[0055] The residual gas of the mixed gas of toxic gas generated by the reaction of disinfectant and wastewater and water vapor generated by heating the wastewater enters the scraper plate 61 after condensation, and is then reintroduced into the wastewater through the injection pipe 62. The reaction force generated when the injection pipe 62 sprays gas drives the scraper plate 61 and the guide block 63 to rotate on the inner wall of the cylinder shell 2 2 and the outer wall of the cylinder shell 3 3 while they can descend. The annular groove 64 can allow wastewater to pass through the guide block 63 during its descent, thereby avoiding the resistance generated by the compression of the wastewater when the guide block 63 descends and affecting the descent process of the guide block 63.

[0056] Among them, the connection between the bottom of cavity 1 5 and the bottom of cavity 3 7 is an oblique annular channel. The bottom of cavity 1 5 is higher than the bottom of cavity 3 7 along the height direction of cylinder shell 1. A drainage pipe 71 is provided at the bottom of cavity 3 7. During specific operation, condensed water formed by water vapor in cavity 1 5 flows to the bottom of cavity 3 7 and converges with the condensed water in cavity 3 7, and is discharged through the drainage pipe 71 for recycling and reuse.

[0057] Reference Figure 2 and Figure 3In order to enable the guide block 63 and the scraper plate 61 to descend along the cylinder shell 2 2 and the cylinder shell 3 3 while rotating, a plurality of spiral grooves 65 are provided on the inner wall of the cylinder shell 2 2, and spiral grooves 65 corresponding to the spiral grooves 65 on the cylinder shell 2 2 are provided on the outer wall of the cylinder shell 3 3.

[0058] The guide block 63 is provided with multiple groups of sliding protrusions 66 corresponding one-to-one with the spiral grooves 65 on the cylinder shell 2 2 at one end close to the cylinder shell 2 2, and the guide block 63 is provided with multiple groups of sliding protrusions 66 corresponding one-to-one with the spiral grooves 65 on the cylinder shell 3 3 at one end close to the cylinder shell 3 3, and each group of sliding protrusions 66 is slidably connected with the spiral groove 65 on its corresponding side.

[0059] Among them, the guide block 63 forms two symmetrical frustum surfaces at the top and bottom along the plane where the annular groove 64 is located. The diameter of the top frustum surface gradually increases from the end close to the annular groove 64 to the end close to the injection pipe 62, and the diameter of the bottom frustum surface gradually decreases from the end close to the bottom of the cylinder shell 22 to the end close to the annular groove 64. The condensed water formed by the water vapor in the rising process of the guide block 63 in the cavity 26 or some precipitated crystal particles can be guided by the frustum surface to re-enter the wastewater to avoid waste of resources.

[0060] When the toxic gas sprayed by the injection pipe 62 drives the scraper plate 61 and the guide block 63 to rotate, each group of sliding protrusions 66 begins to slide synchronously on their corresponding spiral grooves 65, and then the guide blocks 63 can drive the scraper plate 61 to move synchronously during the sliding process of the sliding protrusions 66, so that the scraper plate 61 can spirally descend along the trajectory of the spiral groove 65 while rotating, ensuring that the scraper plate 61 can scrape off the crystalline particles attached to the two side walls of the cavity 2 6 during the descent process, and can also stir the wastewater and disinfectant to ensure that the wastewater and disinfectant can be fully mixed and react, thereby increasing the reaction rate.

[0061] Reference Figure 3 and Figure 4 In order to ensure that the scraper plate 61 that has descended to the bottom of the cavity 6 can be reset, an air pipe 67 is connected to the top of each scraper plate 61, and an air blocking plate 68 is arranged inside the scraper plate 61 to block the injection pipe 62. A movable shaft 69 is symmetrically arranged along the length direction of the air blocking plate 68. The movable shaft 69 passes through the scraper plate 61 and is slidably connected to the scraper plate 61.

[0062] Blocking plates 610 cooperating with the moving shaft 69 are provided at both the beginning and the end of the spiral groove 65 .

[0063] During specific operation, in the initial state, the air blocking plate 68 blocks the injection pipe 62 on one side of the scraper and brush plate 61, and the toxic gas enters the scraper and brush plate 61 through the gas pipe 67, and then is ejected from the injection pipe 62 on the opposite side of the scraper and brush plate 61. The driving force generated by the ejected toxic gas causes the scraper and brush plate 61 to start rotating, and at the same time, it can descend along the spiral groove 65. When it descends to the bottom of the cavity 6, the moving shafts 69 on both sides of the scraper and brush plate 61 touch the blocking plate 610. Under the resistance of the blocking plate 610, the moving shafts 69 on both sides drive the air blocking plate 68 to start sliding in the scraper and brush plate 61, thereby blocking the injection pipe 62 on the side away from the blocking plate 610. At this time, The injection pipe 62 on the side near the baffle plate 610 begins to spray toxic gas, and the toxic gas pushes the scraper plate 61 and the guide block 63 to spiral up. When the scraper plate 61 reaches the top end of the spiral groove 65, the movable shaft 69 touches the baffle plate 610 at the top of the cavity 2 6 again, and the injection pipe 62 that sprays toxic gas changes again, thereby realizing that the scraper plate 61 can repeatedly scrape the crystals attached to the two side walls of the cavity 2 6. At the same time, the scraper plate 61 can also repeatedly stir the wastewater and disinfectant to speed up the reaction rate. Finally, the toxic gas can re-enter the wastewater to react with the disinfectant to ensure the purification effect of the toxic gas.

[0064] Reference Figure 2 The top of cavity 1 5 is provided with a slope cover plate inclined toward the center of cylinder shell 1, the top of cavity 2 6 is uncovered, the top of cavity 3 7 is provided with an annular cover plate, and the top of cavity 4 8 is provided with a circular cover plate.

[0065] A pipe storage tray 9 is provided at the top of the cylinder shell 3 for storing the gas transmission pipe 67 , and the outer edge of the pipe storage tray 9 is located above the cylinder shells 2 2 and 3 .

[0066] Among them, the top and bottom of the pipe storage plate 9 are respectively two conical surfaces. The diameter of the top conical surface of the pipe storage plate 9 gradually decreases from large in the direction away from the pipe storage plate 9 and close to the top of the conical cover 15, and the diameter of the bottom conical surface gradually increases from small in the direction away from the cylinder shell three 3 and close to the pipe storage plate 9. During specific operation, toxic gases and water vapor escape from the wastewater. Since the diameter of the pipe storage plate 9 is between the cylinder shell two 2 and the cylinder shell three 3 and the top of the cavity two 6 is uncovered, the rise of the mixed gas will not be blocked. The condensed water and crystal particles that may be generated during the rising process of the mixed gas can finally fall into the wastewater through the slope cover plate, the two conical surfaces of the pipe storage plate 9 or the guide block 63 to re-participate in the reaction.

[0067] Reference Figure 5 and Figure 6 A plurality of spirally wound gas pipes 67 are arranged in the pipe storage disk 9, and a gas storage tank 91 is arranged in the center of the pipe storage disk 9, and the gas pipes 67 are connected with the gas storage tank 91 through.

[0068] During the spiral ascending process of the scraper plate 61, in order to ensure that the gas pipe 67 can be smoothly recovered into the pipe storage disk 9, each group of gas pipes 67 is provided with a clockwork spring 92 corresponding to the gas pipe 67 near the gas storage tank 91, so that the gas pipe 67 transported out of the pipe storage disk 9 can be smoothly reset. The clockwork spring 92 is sleeved in a limit cover 93, and the limit cover 93 is connected to the inner wall of the top of the pipe storage disk 9. The elastic steel bar of the clockwork spring 92 away from the limit cover 93 is connected to the gas pipe 67, and its spiral direction is the same as that of the gas pipe 67.

[0069] Among them, the elastic steel bar of the clockwork spring 92 extending out of the limit cover 93 is of the same length as the gas pipe 67 and fits tightly, which can effectively ensure that the elastic tension of the clockwork spring 92 can act on all parts of the gas pipe 67. During specific operation, the toxic gas remaining after the mixed gas is condensed enters the gas storage tank 91, and the toxic gas in the gas storage tank 91 is output to the scraper plate 61 through the gas pipe 67 and drives the scraper plate 61 to spirally descend. When the scraper plate 61 spirally descends, it drives the gas pipe 67 in the storage tube plate 9 to spirally descend together, and the clockwork spring 92 generates an elastic tension. However, at this time, since the elastic tension of the clockwork spring 92 is less than the driving force of the toxic gas, the scraper plate 61 maintains a descending state. When the scraper plate 61 descends to the bottom of the cavity 2 6, switches the movement direction and starts to rise, the clockwork spring 92 drives the gas pipe 67 to start to contract, and ensures that after the scraper plate 61 is reset, the gas pipe 67 can also be smoothly reset.

[0070] Reference Figure 7 In order to condense the water vapor in the mixed gas, a condensation pan 10 is provided at one end of the storage pipe pan 9 away from the cylinder shell 3. Three spiral channels are provided inside the condensation pan 10. The spiral channel that penetrates the condensation pan 10 to form a passage is a cold water channel 101, which condenses the water vapor in the mixed gas. The cold water channel 101 and the two penetration ports of the condensation pan 10 are respectively a water inlet 102 and a water outlet 103. The water inlet 102 and the water outlet 103 are symmetrically arranged along the center of the condensation pan 10. The other two spiral channels are both air inlet channels 104. The two air inlet channels 104 are symmetrically arranged along the center of the condensation pan 10.

[0071] Among them, the bottom of the condensation plate 10 is in a truncated cone shape, and its diameter becomes smaller as it gets closer to the storage pipe plate 9, and the partitions separating the three spiral channels have good thermal conductivity. During specific operation, cold water is input into the water inlet 102 and output from the water outlet 103 through a complete spiral channel. When the mixed gas in the two air inlet channels 104 floats along the spiral channels toward the center of the condensation plate 10, the cold water on both sides condenses the water vapor into water. The condensed water is blown by the mixed gas and converges toward the center of the condensation plate 10 along the conical bottom. In the process of the mixed gas floating toward the center of the condensation plate 10, the water vapor in the mixed gas gradually decreases, and the proportion of toxic gas gradually increases, thereby realizing the separation of toxic gas and water vapor.

[0072] Reference Figure 5 and Figure 7 An air inlet 105 is provided at the bottom of the air inlet channel 104 away from the center of the circle, and a water outlet 106 is provided at the bottom of the air inlet channel 104 close to the center of the circle.

[0073] A condensate tank 14 is installed at the bottom of the condensate tray 10 to collect the condensate in the condensate tray 10 . The drain port 106 is connected to the condensate tank 14 . A water outlet pipe 141 is installed on the condensate tank 14 . The water outlet pipe 141 is connected to the circular cover plate and the condensate tank 14 .

[0074] During the specific implementation process, the mixed gas enters the air inlet channel 104 from the air inlets 105 on both sides of the bottom of the condensation tray 10. After a complete condensation process, the formed condensed water is guided by the conical bottom of the condensation tray 10 and blown by the mixed gas, and finally enters the condensation water tank 14 from the water outlet 106 of the air inlet channel 104. After the condensed water in the condensation water tank 14 reaches a specific water level, the condensed water collected in the condensation tray 10 is discharged and collected through the water outlet pipe 141 under the drive of an external water pump (not shown in the figure), thereby saving resources and protecting the environment.

[0075] Reference Figure 2 and Figure 8 In order to reuse the toxic gas in the condensation pan 10, an air outlet 107 is provided at the top of the air inlet channel 104 near the center of the circle, and a guide air pump 108 is provided at the top of the air outlet 107 to extract the gas in the condensation pan 10. An air guide pipe 109 is provided at the center of the bottom of the guide air pump 108. The air outlet end of the guide air pump 108 is connected to the air inlet end of the air guide pipe 109. The air guide pipe 109 passes through the condensation pan 10 and the condensed water tank 14 and is connected to the air storage tank 91.

[0076] An air inlet pipe 110 with a semicircular plane for controlling the flow direction of gas is installed between the bottom of the air storage tank 91 and the circular cover plate. The air inlet pipe 110 is connected to the air storage tank 91 and the circular cover plate of the cavity 24 8.

[0077] A rotating rod 111 is arranged in the air guide pipe 109, and a knob 112 is installed on a portion of the rotating rod 111 extending beyond the top of the guide air pump 108 at one end of the rotating rod 111 away from the air guide pipe 109. The flow direction of the toxic gas in the gas storage tank 91 can be controlled by adjusting the knob 112. The rotating rod 111 is sleeved in the guide air pump 108 and the rotating rod 111 is connected to the gas storage tank 91 through a bearing. A semicircular air baffle 113 is arranged at one end of the air guide pipe 109 away from the guide air pump 108 to block the output of the toxic gas. The end of the rotating rod 111 away from the guide air pump 108 is connected to the center of the air baffle 113. The air guide pipe 109 has the same radius as the air inlet pipe 110, and the air baffle 113 and the air inlet pipe 110 are slidably connected.

[0078] Among them, the air duct 109 passes through the cold water channel 101 without blocking the cold water channel 101. In the initial state, the air baffle 113 completely covers the pipe opening of the air inlet pipe 110. During the specific implementation process, the guide air pump 108 introduces the toxic gas remaining after condensation treatment in the condensation plate 10 into the air duct 109 through the air outlet 107. At this time, by adjusting the knob 112 on the top of the rotating rod 111, each rotation of 180 degrees can control the flow direction of the toxic gas in the air duct 109.

[0079] When the air baffle 113 coincides with the opening of the air inlet pipe 110, the toxic gas enters the gas storage tank 91 and enters the scraper plate 61 through the air supply pipe 67; when the knob 112 rotates 180 degrees, that is, the rotating rod 111 drives the air baffle 113 to rotate 180 degrees, so that the half opening of the air guide pipe 109 without the air baffle 113 coincides with the opening of the air inlet pipe 110, the toxic gas enters the cavity 28 through the air inlet pipe 110.

[0080] Embodiment 2:

[0081] Refer to the figure Fig. 9 and Fig.10 An elastic telescopic rod 81 is installed at the bottom of the circular cover plate, and one end of the elastic telescopic rod 81 away from the circular cover plate is connected to a compression plate 82, and the compression plate 82 is slidably connected to the cavity four 8.

[0082] A plurality of oblique channels 83 are provided at the bottom of the cavity 2 6 and the cavity 4 8 , and the end of the oblique channel 83 away from the cylinder shell 4 4 is higher than the end close to the cylinder shell 4 4 , and the oblique channel 83 is not connected to the cavity 3 7 .

[0083] Among them, since the water vapor in cavity three 7 flows through the water vapor in cavity one 5, the water vapor content in cavity three 7 is lower than the water vapor content in cavity one 5, so the heating efficiency of the water vapor in cavity three 7 is lower than the heating efficiency of the water vapor in cavity two 6, so the water vapor in cavity three 7 can preliminarily heat the wastewater in cavity four 8. In the specific implementation process, because the disinfectant is directly introduced into cavity two 6, the main occasions for the reaction between the wastewater and the disinfectant are concentrated in cavity two 6. When the reaction rate of the wastewater in cavity two 6 slows down and the liquid level drops, the toxic gas is introduced into cavity four 8 through the air inlet pipe 110 by controlling the knob 112 and the compression plate 8 is pushed. 2 moves downward, the compression plate 82 compresses the wastewater in the cavity four 8 into the cavity two 6, and at the same time injects disinfectant into the cavity two 6. At this time, the wastewater entering the cavity two 6 through the cavity four 8 has a certain heat after being preheated by the water vapor in the cavity three 7, and can react with the disinfectant more quickly. At the same time, the knob 112 is turned to adjust the flow direction of the toxic gas, and the scraper plate 61 is driven to stir the wastewater, so that the gas and the wastewater are re-evenly mixed, which can further accelerate the reaction rate of the wastewater and the disinfectant. In addition, the stirring of the wastewater by the scraper plate 61 makes the wastewater flow, so that the wastewater will not only exchange heat with the cavity one 5 or the cavity three 7, thereby making the heating of the wastewater more uniform.

[0084] When the waste water in cavity two 6 and cavity four 8 evaporates to the end, adjust the knob 112 to rotate it 90 degrees. At this time, only half of the air baffle 113 covers the air outlet pipe, and the end of the air guide pipe 109 away from the condensation plate 10 has a 1 / 4 pipe opening connected to the air storage tank 91. The toxic gas in cavity four 8 enters the air storage tank 91 under the cooperation of the air outlet pipe and the air guide pipe 109, and is then discharged through the air supply pipe 67. At the same time, the toxic gas in cavity four 8 flows out, the pressure decreases, and the elastic telescopic rod 81 drives the compression plate 82 to start resetting. During the resetting process, the toxic gas is squeezed to accelerate the discharge of the toxic gas.

[0085] After the wastewater is completely evaporated, the channel connecting the bottom of cavity one 5 and cavity three 7 will allow the crystal particles at the bottom of cavity two 6 and the crystal particles at the bottom of cavity two 6 to enter the bottom of cavity four 8 through the oblique channel 83. At this time, the bottom of cavity four 8 is removed to collect the crystal particles.

[0086] Reference Fig.11 The present invention also provides a method for treating wastewater containing high-salt organic matter and high-concentration unbearable odor, comprising the following steps:

[0087] S1: Low-temperature evaporation: wastewater enters the wastewater treatment device with high-salt organic matter and high-concentration unbearable odor, and the wastewater is evaporated and condensed by the water vapor in the cavity 1 5 and the cavity 3 7 to obtain desalinated water;

[0088] S2: Gas circulation: The toxic gas obtained in step S1 is introduced into the wastewater again through the gas pipeline 67 for reaction;

[0089] S3: preheating of wastewater: the wastewater in chamber four 8 that has been preheated in chamber three 7 is pressed into chamber two 6 through compression plate 82 for reaction;

[0090] S4: Desalinated water recovery: recovering the desalinated water in step S1;

[0091] S5: Crystal collection: Collect the crystals obtained by evaporating and concentrating the wastewater.

[0092] The implementation principle of the present invention is:

[0093] 1: Water vapor is introduced into cavity 15 through the water vapor pipe 11. Since cavity 15 and cavity 37 are connected at the bottom, water vapor can fill cavity 15 and cavity 37. Since the water vapor temperature at the top of cavity 15 and cavity 37 is higher than that at the bottom, in order to avoid uneven heating of the wastewater, the circulating air pump 52 is started. The circulating air pump 52 introduces the water vapor with high temperature at the top of cavity 15 and cavity 37 to the bottom through the circulating air pipe 51, thereby continuously circulating the water vapor to ensure that the water vapor temperature at various places in cavity 15 and cavity 37 can be kept consistent, so that the water vapor can evenly heat the wastewater.

[0094] 2: The residual gas of the mixed gas of toxic gas generated by the reaction of disinfectant and wastewater and water vapor generated by heating the wastewater enters the scraper plate 61 after condensation, and is then reintroduced into the wastewater through the injection pipe 62. The reaction force generated when the injection pipe 62 injects gas drives the scraper plate 61 and the guide block 63 to rotate on the inner wall of the cylinder shell 2 2 and the outer wall of the cylinder shell 3 3 while being able to descend.

[0095] 3: The connection between the bottom of cavity 15 and the bottom of cavity 37 is an oblique annular channel. The bottom of cavity 15 is higher than the bottom of cavity 37 along the height direction of cylinder shell 1. A drainage pipe 71 is provided at the bottom of cavity 37. During operation, the condensed water formed by the water vapor in cavity 15 flows to the bottom of cavity 37 and converges with the condensed water in cavity 37, and is discharged through the drainage pipe 71 for recycling.
