Description

Technical Field

[0001] This invention relates to the field of wind power operation and maintenance, and in particular to cleaning equipment and methods for engine nacelles. Background Technology

[0002] In recent years, wind power installed capacity has experienced explosive growth, with the scale of installations gradually increasing. However, this has also brought about more and more operation and maintenance problems. Currently, the vast majority of wind turbines installed and connected to the grid are doubly-fed or semi-direct-drive types, all of which have gearbox structures. During operation, doubly-fed and semi-direct-drive wind turbines experience oil leaks in key structures such as the gearbox, generator, and hydraulic station. The leaked oil spreads to the bottom of the nacelle and tower, causing serious oil pollution over time. This not only causes external pollution and corrosion of the outer paint film on the wind turbine, but also pollutes the local environment, negatively impacting wind turbine manufacturers and wind farm management.

[0003] Currently, cleaning oil stains on wind turbine surfaces mainly relies on manual labor, primarily focusing on the turbine tower. However, the nacelle bottom is located at the top of the tower, perpendicular to the tower wall, typically at a height of 60-100 meters. This area is large, lacks support points, and makes manual cleaning extremely difficult. Furthermore, there is a lack of automated cleaning equipment for the nacelle bottom. Therefore, there is an urgent need for cleaning equipment and methods for the nacelle to address these issues. Summary of the Invention

[0004] One object of the present invention is:

[0005] We provide cleaning equipment for the engine room. The crawling mechanism can crawl along the tower wall and lift the cleaning unit to the top of the tower. The cleaning unit adheres to the bottom of the engine room and cleans the bottom of the engine room, completing the cleaning operation efficiently and safely.

[0006] Another object of the present invention is:

[0007] We provide cleaning methods for engine rooms, replacing traditional manual high-altitude operations with cleaning equipment, reducing the risks of high-altitude work for personnel, and effectively improving cleaning efficiency, thereby improving the operation and maintenance efficiency of wind farms.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] Firstly, a cleaning device is provided for an engine room, the engine room being located at the top of a tower, the cleaning device comprising:

[0010] A crawling mechanism, which is capable of attaching to and crawling along the wall of the tower.

[0011] A cleaning mechanism, comprising a frame assembly and a cleaning assembly, is rotatably connected to the crawling mechanism. The frame assembly has a plurality of adsorption elements at one end facing the bottom of the cabin, the adsorption elements being able to adsorb onto the bottom of the cabin. The cleaning assembly is connected to the frame assembly and is used to clean the bottom of the cabin.

[0012] A pushing component is disposed between the crawling mechanism and the cleaning mechanism. The output end of the pushing component is connected to the cleaning mechanism. The pushing component can push the cleaning mechanism to rotate toward the bottom of the cabin so that the cleaning mechanism is attached to the bottom of the cabin.

[0013] Preferably, the crawling mechanism includes at least two spaced-apart drive components. Each drive component includes a magnetic element, a track, a first rotating wheel, and a second rotating wheel. The track is wound between the first rotating wheel and the second rotating wheel. The magnetic element is disposed between the first rotating wheel and the second rotating wheel and abuts against the inner wall of the track. The magnetic element is used to attract the wall surface of the tower.

[0014] Preferably, the outer periphery of the first rotating wheel and the outer periphery of the second rotating wheel are provided with toothed structures, the inner wall of the track is provided with toothed structures, and the track meshes with the first rotating wheel and the second rotating wheel for transmission.

[0015] Preferably, the drive assembly further includes a fixed wheel and two magnetic components. The fixed wheel is disposed between the two magnetic components and connected to the two magnetic components. When the magnetic components press against the inner wall of the track and are attracted to the tower wall, the fixed wheel presses against the inner wall of the track, so that the outer wall of the track is attached to the tower wall.

[0016] Preferably, the frame assembly includes a first frame and a second frame, the first frame and the second frame are slidably connected along a first direction, and a plurality of the adsorption elements are provided at one end of the first frame and the second frame facing the bottom of the cabin. The cleaning assembly includes a first cleaning assembly and a second cleaning assembly, the first cleaning assembly and the first frame are slidably connected along the first direction, and the second cleaning assembly and the second frame are slidably connected along the first direction.

[0017] Preferably, both the first cleaning assembly and the second cleaning assembly include a cleaning roller, which is rotatable about its central axis, and the outer periphery of the cleaning roller is covered with a flexible cleaning element for wiping oil stains from the bottom of the cabin.

[0018] Preferably, both the first cleaning assembly and the second cleaning assembly include a cleaning hood with the opening facing the bottom of the cabin. The cleaning hood is equipped with a high-pressure nozzle connected to a clean water pipe. The high-pressure nozzle can spray a high-pressure water jet to flush away the oil stains on the bottom of the cabin. The bottom of the cleaning hood is equipped with a wastewater recovery hole connected to a wastewater pipe. The wastewater recovery hole is used to recover the wastewater generated after the high-pressure nozzle flushes away the oil stains.

[0019] Preferably, the cleaning hood is provided with a cleaning hood guide rail extending in a second direction, and the high-pressure nozzle is slidably connected to the cleaning hood guide rail, wherein the second direction is set at an angle to the first direction.

[0020] Preferably, the port of the cleaning hood is provided with an elastic seal, which is used to seal the gap between the cleaning hood and the bottom of the cabin.

[0021] Secondly, a cleaning method for an aircraft cabin is provided, implemented using the aforementioned cleaning equipment, the cleaning method comprising the following steps:

[0022] S100. Attach the crawling mechanism to the wall of the tower and control the crawling mechanism to crawl along the wall of the tower to the top of the tower.

[0023] S200: Control the pushing component to push the cleaning mechanism to rotate toward the bottom of the cabin, so that the cleaning mechanism is attached to the bottom of the cabin;

[0024] S300. Activate the adsorption component to adsorb onto the bottom of the cabin and fix the frame assembly.

[0025] S400: Start the cleaning assembly to clean the bottom of the cabin;

[0026] S500, shut down the adsorption element to make it lose its adsorption force, control the pushing component to pull the cleaning mechanism away from the bottom of the cabin, and the crawling mechanism returns to the ground along the tower wall to retrieve the cleaning equipment.

[0027] The beneficial effects of this invention are as follows:

[0028] On one hand, the present invention provides a cleaning device for an engine compartment, including a crawling mechanism, a cleaning mechanism, and a pushing assembly. Since the engine compartment is located at the top of the tower, the crawling mechanism can adhere to and crawl along the tower wall to lift the cleaning mechanism to the top of the tower, i.e., to bring the cleaning mechanism closer to the bottom of the engine compartment. The bottom of the engine compartment is perpendicular to the tower wall. The cleaning mechanism and the crawling mechanism are rotatably connected. When the crawling mechanism is in a crawling state, the cleaning mechanism rotates closer to the crawling mechanism, bringing the center of gravity of the cleaning device closer to the wall, preventing the crawling mechanism from tipping over and reducing crawling distance. The energy consumption of the mechanism is as follows: after the crawling mechanism reaches the top of the tower, the pushing component pushes the cleaning mechanism to rotate towards the bottom of the nacelle until the cleaning mechanism is attached to the bottom of the nacelle. The cleaning mechanism includes a frame assembly and a cleaning assembly. The end of the frame assembly facing the bottom of the nacelle is provided with several adsorption components. When the frame assembly comes into contact with the bottom of the nacelle, the adsorption components are activated and have adsorption force, which can adsorb to the bottom of the nacelle and fix the frame assembly. The cleaning assembly is connected to the frame assembly. After the frame assembly is fixed, the cleaning assembly can clean the bottom of the nacelle, thereby completing the cleaning operation efficiently and safely.

[0029] On the other hand, the present invention provides a cleaning method for the nacelle. Using the above-mentioned cleaning equipment, the crawling mechanism is controlled to crawl to the top of the tower, the cleaning mechanism is attached to the bottom of the nacelle and fixed by adsorption components, the cleaning components are controlled to clean the bottom of the nacelle, and the cleaning equipment is controlled to be recycled after cleaning. The cleaning equipment replaces traditional manual high-altitude operations, reduces the risk of high-altitude operations for personnel, and effectively improves cleaning efficiency, thereby improving the operation and maintenance efficiency of wind farms.

[0048] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0049] Example 1:

[0050] like Figures 1 to 5As shown, this embodiment provides a cleaning device for an engine compartment. The engine compartment is located at the top of a tower. The cleaning device includes a crawling mechanism 1, a cleaning mechanism 2, and a pushing assembly 3. The crawling mechanism 1 can adhere to the wall of the tower and crawl along the wall to lift the cleaning mechanism 2 to the top of the tower, i.e., to bring the cleaning mechanism 2 closer to the bottom of the engine compartment. The cleaning mechanism 2 includes a frame assembly and a cleaning assembly. Since the bottom of the engine compartment is perpendicular to the tower wall, the cleaning mechanism 2 is rotatably connected to the crawling mechanism 1. The frame assembly has several adsorption elements 23 at one end facing the bottom of the engine compartment, which can adsorb onto the bottom of the engine compartment. The cleaning assembly is connected to the frame assembly and is used to clean the bottom of the engine compartment. The pushing assembly 3 is located between the crawling mechanism 1 and the cleaning mechanism 2. The output end of the pushing assembly 3 is connected to the cleaning mechanism 2, and the pushing assembly 3 can push the cleaning mechanism 2 to rotate towards the bottom of the engine compartment, so that the cleaning mechanism 2 adheres to the bottom of the engine compartment. When the crawling mechanism 1 is in the crawling state, the cleaning mechanism 2 rotates and approaches the crawling mechanism 1, making the center of gravity of the cleaning equipment closer to the wall, preventing the crawling mechanism 1 from tipping over and reducing the energy consumption of the crawling mechanism 1. When the crawling mechanism 1 reaches the top of the tower, the pushing component 3 pushes the cleaning mechanism 2 to rotate towards the bottom of the nacelle until the cleaning mechanism 2 is attached to the bottom of the nacelle. When the frame component comes into contact with the bottom of the nacelle, the adsorption component 23 starts to have an adsorption force, which can adsorb onto the bottom of the nacelle and fix the frame component. The cleaning component is connected to the frame component. After the frame component is fixed, the cleaning component can clean the bottom of the nacelle, thereby completing the cleaning operation efficiently and safely.

[0051] For example, the adsorption element 23 is an electromagnet. When the electromagnet is energized, it has magnetism and can be magnetically adsorbed to the bottom of the cabin. When the electromagnet is de-energized, it loses magnetism and can detach from the bottom of the cabin.

[0052] In other embodiments, the adsorption element 23 is a vacuum suction head, which can be vacuum adsorbed onto the bottom of the cabin.

[0053] For example, the frame assembly is rotatably connected to the crawling mechanism 1, and when the pushing component 3 pushes the frame assembly to rotate, it simultaneously drives the cleaning component to move closer to or away from the bottom of the cabin.

[0054] For example, the pushing component 3 includes a linear drive 31 and a telescopic rod 32. The linear drive 31 is fixedly installed on the crawling mechanism 1 and can control the extension and retraction of the telescopic rod 32. The cleaning mechanism 2 is provided with a connecting plate 26 for fixedly connecting the frame assembly. The movable end of the telescopic rod 32 is rotatably connected to the connecting plate 26. Furthermore, there are two telescopic rods 32, which are spaced apart along the second direction. By pushing or pulling the connecting plate 26 simultaneously with the two telescopic rods 32, the stability of the connecting plate 26 during movement can be ensured, thereby ensuring the stability of the frame assembly during rotation and preventing the frame assembly from tilting and failing to attach to the bottom of the cabin.

[0055] For example, the linear drive 31 is a linear motor; in other embodiments, the linear drive 31 is a hydraulic cylinder or other linear drive mechanism.

[0056] In this embodiment, the first direction is the x-axis direction, the second direction is the y-axis direction, the first direction is the length direction of the frame component, the second direction is the width direction of the frame component, and the first direction is perpendicular to the second direction.

[0057] like Figure 2 and Figure 3 As shown, the crawling mechanism 1 includes two spaced-apart drive components 11. Each drive component 11 includes a magnetic element 114, a track 113, a first rotating wheel 111, and a second rotating wheel 112. The track 113 is wound between the first rotating wheel 111 and the second rotating wheel 112. The magnetic element 114 is disposed between the first rotating wheel 111 and the second rotating wheel 112 and abuts against the inner wall of the track 113. The magnetic element 114 is used to magnetically adsorb the wall of the tower. For example, the magnetic element 114 is a permanent magnet, and the track 113 is a rubber track. The magnetic element 114 magnetically adsorbs the tower wall, reducing the crawling resistance of the drive component 11 and reducing the energy consumption of the crawling mechanism 1.

[0058] For example, the crawling mechanism 1 also includes a housing 12, which contains a controller. Two drive components 11 are respectively disposed on both sides of the housing 12. The first rotating wheel 111 and the second rotating wheel 112 are electrically connected to the controller. The controller can control each first rotating wheel 111 and each second rotating wheel 112. The four rotating wheels are electrically connected to a rotary driver, that is, the crawling mechanism 1 is four-wheel drive, which increases the driving force of the crawling mechanism 1. As the driving force increases, the magnetic force of the magnetic component 114 can increase synchronously. Using a stronger magnetic component 114 improves the adsorption force of the magnetic component 114 on the tower wall, ensuring that the crawling mechanism 1 can be firmly adsorbed on the tower wall, and preventing the crawling mechanism 1 from falling off during the crawling process and causing damage to the cleaning equipment.

[0059] Furthermore, the controller is equipped with a differential control module, which can perform differential control on the drive component 11, enabling the crawling mechanism 1 to turn on the vertical wall and allowing the operator to control the crawling mechanism 1 more flexibly.

[0060] In other embodiments, the first rotating wheel 111 is the driving wheel, the second rotating wheel 112 is the driven wheel, and the crawling mechanism 1 is driven by both wheels, which reduces the energy consumption of the crawling mechanism 1 and prevents the track 113 from slipping.

[0061] For example, the outer periphery of the first rotating wheel 111 and the second rotating wheel 112 is provided with a gear structure, and the inner wall of the track 113 is provided with a rack structure. The track 113 meshes with the first rotating wheel 111 and the second rotating wheel 112 to increase the friction between the track 113 and the first rotating wheel 111 and the second rotating wheel 112, thereby preventing the track 113 from slipping.

[0062] For example, the drive assembly 11 also includes a fixed wheel 115 and two magnetic elements 114. The fixed wheel 115 is disposed between the two magnetic elements 114 and connected to the two magnetic elements 114. The bottom of the fixed wheel 115 is flush with the bottom of the magnetic elements 114. When the magnetic elements 114 press against the inner wall of the track 113 and are attracted to the tower wall, the fixed wheel 115 presses against the inner wall of the track 113. Since the tower wall is curved, the fixed wheel 115 can make the outer wall of the track 113 fit tightly against the tower wall, ensuring that the drive assembly 11 can crawl stably.

[0063] For example, the outer side of the drive assembly 11 is provided with a sealing plate 116, which is used to protect the internal components of the drive assembly 11 and prevent dust, oil and other debris from entering the drive assembly 11 and affecting its operation.

[0064] For example, the cleaning equipment also includes a camera 13, which is fixedly connected to the housing 12 and electrically connected to the controller. The camera 13 is used to monitor the working process of the cleaning equipment and record the working process.

[0065] For example, the outer surface of the housing 12 is provided with a power cord interface 14 and a communication line interface 15. The power cord interface 14 is used to connect to an external power source, and the communication line interface 15 is used to connect to an external control device. The operator can remotely control the cleaning equipment, and the external power source can ensure that the cleaning equipment has sufficient power supply and can support the long-term operation of the cleaning equipment.

[0066] For example, the outer surface of the housing 12 is also provided with a lifting lug 16, which is used to bind the safety rope, fix the power cord and signal line, and further improve the safety performance of the cleaning equipment.

[0067] like Figure 4 As shown, the frame assembly includes a first frame 211 and a second frame 212. The first frame 211 and the second frame 212 are slidably connected along a first direction. Each of the first frame 211 and the second frame 212 is provided with a plurality of adsorption elements 23 at one end facing the bottom of the cabin. The adsorption elements 23 are electrically connected to the controller. The cleaning assembly includes a first cleaning assembly 221 and a second cleaning assembly 222. The first cleaning assembly 221 is slidably connected to the first frame 211 along a first direction, and the second cleaning assembly 222 is slidably connected to the second frame 212 along a first direction.

[0068] For example, the frame assembly includes a first guide rail 213, a second guide rail 214, and a third guide rail 215. The first frame 211 has a rectangular structure. The first guide rail 213 is disposed on both sides of the outer periphery of the first frame 211 and is fixedly connected to the first frame 211. The second frame 212 has a U-shaped structure. The opening of the second frame 212 faces the first frame 211. The second frame 212 is slidably connected to the first frame 211 through the first guide rail 213. The first frame 211 can be inserted into the second frame 212 along the opening of the second frame 212. When the cleaning device is in the crawling state, the first frame 211 is inserted into the second frame 212, so that the overall center of gravity of the frame assembly is close to the crawling mechanism 1. When the cleaning device is ready to enter the cleaning state, the second frame 212 extends away from the first frame 211, expanding the cleaning range of the cleaning mechanism 2. The second guide rail 214 is disposed at the top of the first frame 211 and is fixedly connected to the first frame 211. A first slider 216 is slidably disposed on the second guide rail 214, and the first cleaning component 221 is rotatably connected to the first slider 216. The third guide rail 215 is disposed at the top of the second frame 212 and is fixedly connected to the second frame 212. A second slider 217 is slidably disposed on the third guide rail 215, and the second cleaning component 222 is rotatably connected to the second slider 217.

[0069] In this embodiment, the first frame 211 is rotatably connected to the housing 12, and the connecting plate 26 is fixedly connected to the first frame 211.

[0070] For example, both the first cleaning assembly 221 and the second cleaning assembly 222 include a cleaning roller 223, which is rotatable about its central axis. The outer periphery of the cleaning roller is covered with a flexible cleaning element 220, which is used to wipe oil stains on the bottom of the cabin.

[0071] For example, the first guide rail 213, the second guide rail 214 and the third guide rail 215 are all motorized guide rails.

[0072] Example 2:

[0073] like Figure 6 and Figure 7 As shown, based on Embodiment 1, this embodiment provides another cleaning device for the engine room, which differs from Embodiment 1 in that:

[0074] Both the first cleaning assembly 221 and the second cleaning assembly 222 include a cleaning hood 224. The opening of the cleaning hood 224 faces the bottom of the cabin. The cleaning hood 224 is equipped with a high-pressure nozzle 225 and a high-pressure spray bar. The cleaning mechanism 2 also includes a clean water pipe 24 and a wastewater pipe 25. The clean water pipe 24 is used to provide clean water to the cleaning mechanism 2, and the wastewater pipe 25 is used to collect and discharge wastewater. The high-pressure spray bar is connected to the clean water pipe 24, and the high-pressure nozzle 225 is connected to the high-pressure spray bar. The high-pressure nozzle 225 can spray out a high-pressure water jet and wash away the oil stains at the bottom of the cabin. The bottom of the cleaning hood 224 is equipped with a wastewater recovery hole 226, which is connected to the wastewater pipe 25. The wastewater recovery hole 226 is used to recover the wastewater generated after the high-pressure nozzle 225 washes away the oil stains.

[0075] Furthermore, the water purification pipe 24 provides high-temperature purified water to the cleaning mechanism 2, further improving the cleaning effect of the cleaning components.

[0076] For example, the cross-section of the cleaning hood 224 is trapezoidal or conical, and the sewage can be collected at the top of the cleaning hood 224 and flow into the sewage pipe 25 through the sewage recovery port.

[0077] For example, multiple high-pressure nozzles 225 are provided, and the multiple high-pressure nozzles 225 are evenly arranged along the second direction to increase the rinsing area and improve the cleaning efficiency.

[0078] For example, the cleaning hood 224 is provided with a cleaning hood guide rail 227 extending in the second direction, and a cleaning hood slider 228 is provided between the high-pressure spray bar and the cleaning hood guide rail 227. The high-pressure spray bar is slidably connected to the cleaning hood guide rail 227 through the cleaning hood slider 228, so that the high-pressure nozzle 225 can flush various positions on the bottom of the cabin.

[0079] For example, the port of the cleaning hood 224 is provided with an elastic seal 229, which abuts against the bottom of the cabin. The elastic seal 229 is used to seal the gap between the cleaning hood 224 and the bottom of the cabin. The elastic seal 229 is made of a waterproof and wear-resistant sealing material such as silicone or rubber.

[0080] For example, both the sewage pipe 25 and the clean water pipe 24 are fixed to the lifting lug 16 to ensure the stable operation of the cleaning equipment.

[0081] Example 3:

[0082] like Figure 8 As shown, the present invention also provides a cleaning method for an aircraft cabin, the cleaning method comprising the following steps:

[0083] S100. Attach the crawling mechanism 1 to the wall of the tower and control the crawling mechanism 1 to move along the wall of the tower to the top of the tower.

[0084] S200, the control and push assembly 3 pushes the cleaning mechanism 2 to rotate toward the bottom of the cabin, so that the cleaning mechanism 2 is attached to the bottom of the cabin;

[0085] S300, activate the adsorption component 23 to adsorb onto the bottom of the cabin and fix the frame assembly;

[0086] S400: Start the cleaning unit to clean the bottom of the engine compartment;

[0087] S500, close the adsorption element 23 to make the adsorption element 23 lose its adsorption force, control the push component 3 to pull the cleaning mechanism 2 away from the bottom of the nacelle, and the crawling mechanism 1 returns to the ground along the tower wall to recover the cleaning equipment.

[0088] When faced with different levels of contamination at the bottom of the cabin, different cleaning methods and corresponding cleaning components need to be selected.

[0089] When the bottom of the engine compartment is mainly covered with dry, gritty oil, a roller cleaning method is selected. Equipped with the cleaning equipment described in Example 1, the cleaning roller 223 is installed on the frame assembly. The remote-controlled crawling mechanism 1 carries the cleaning mechanism 2 to the top of the tower. The pushing assembly 3 pushes the connecting plate 26, pushing the first frame 211 to the bottom of the engine compartment. The suction component 23 on the first frame 211 abuts against the bottom of the engine compartment, activating the suction component 23. The suction component 23 on the first frame 211 adheres to the bottom of the engine compartment, fixing the first frame 211 to the bottom. The first guide rail 213 is then driven, causing the second frame 212 to extend away from the first frame 211, increasing the cleaning area. Since the first frame 211 is already fixed, the extension of the second frame 212, causing a change in the center of gravity, will not cause the cleaning equipment to fall off. After the second frame 212 extends, the suction component 23 on the second frame 212 is activated, fixing the second frame 212 to the bottom of the engine compartment as well. The second guide rail 214 and the third guide rail 215 drive the cleaning roller 223 to slide back and forth along the first direction. During the sliding process, the friction force drives the cleaning roller 223 to rotate synchronously. The flexible cleaning element 220 covering the surface of the cleaning roller 223 can wipe away the oil stains at the bottom of the machine compartment during the sliding process. After the cleaning work is completed, the adsorption element 23 is turned off in sequence, and the cleaning equipment is recycled.

[0090] When the bottom of the engine compartment is not covered with dry, gritty oil, a high-temperature, high-pressure water cleaning method is selected. The cleaning equipment described in Example 2 is used. The cleaning hood 224 is installed on the frame assembly, followed by the sequential installation of the clean water pipe 24, wastewater pipe 25, high-pressure spray bar, and high-pressure nozzle 225. The input end of the clean water pipe 24 is connected to a high-temperature clean water tank, and the output end of the wastewater pipe 25 is connected to a wastewater collection / treatment tank. The remote-controlled crawling mechanism 1 carries the cleaning mechanism 2, clean water pipe 24, and wastewater pipe 25 to the top of the tower. The pushing assembly 3 pushes the connecting plate 26, pushing the first frame 211 to the bottom of the engine compartment. The adsorption component 23 located on the first frame 211 abuts against the bottom of the engine compartment, activating the first frame 211. The adsorption element 23, located on the first frame 211, adsorbs the bottom of the machine compartment. The first frame 211 is fixed to the bottom of the machine compartment. Driving the first guide rail 213, the second frame 212 extends away from the first frame 211, activating the adsorption element 23 located on the second frame 212, thus fixing the second frame 212 to the bottom of the machine compartment as well. Driving the second guide rail 214 and the third guide rail 215 causes the cleaning roller 223 to slide back and forth in the first direction, opening the high-pressure nozzle 225 to flush the oil stains at the bottom of the machine compartment. Controlling the washing hood guide rail 227 to move the high-pressure nozzle 225, the bottom of the machine compartment is thoroughly rinsed. Wastewater is recycled through the wastewater pipe 25. After the cleaning work is completed, the adsorption element 23 is turned off sequentially, and the cleaning equipment is recycled.
