Description

Technical Field

[0001] This application relates to the field of battery production equipment technology, and in particular to a cleaning device and tail discharge system. Background Technology

[0002] Silane is a crucial material used in the processes of positive film deposition, back film deposition, polysilicon deposition (POLY), and atomic layer deposition (ALD) in solar cell manufacturing workshops. The combustion of silane produces a large amount of silica powder. During exhaust gas transport, this silica powder gradually adheres to the inner wall of the pipes, forming dust, and the dust thickness increases over time. To ensure exhaust gas transport capacity, the commonly used method is to manually disassemble the pipes periodically and use cleaning brushes to remove the dust from the inner walls.

[0003] However, manual cleaning of pipelines is inefficient and can only be done when the machine is stopped. The process of dismantling pipelines is cumbersome and labor-intensive. In addition, dust is generated during pipeline dismantling and cleaning, which will pollute the equipment and the ground, affecting the production environment and product quality in the workshop. Utility Model Content

[0004] This utility model discloses a cleaning device and a tailpipe system. A cleaning component extending along the extension direction of the pipeline contacts the inner wall of the pipeline. When the cleaning component rotates, it cleans the powder adhering to the inner wall of the pipeline, achieving the purpose of cleaning without manually disassembling the pipeline.

[0005] To achieve the above objectives, the first aspect of this utility model discloses a cleaning device, comprising:

[0006] The cleaning pipeline is used to connect one end to the exhaust gas pretreatment equipment and the other end to the exhaust gas treatment equipment.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0029] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0030] Furthermore, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0031] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0032] In the solar cell manufacturing workshop, silane is an important process material used in the positive film, back film, polycrystalline silicon deposition, and atomic layer deposition processes. The combustion of silane produces a large amount of silicon dioxide powder. The current process involves using a vacuum pump to generate negative pressure to draw the silane out of the machine's internal cavity. This silane is then burned in a pre-treatment system within the workshop, converting it into exhaust gas containing silicon dioxide and other substances. The exhaust gas is then piped to the factory floor, where it undergoes further treatment to meet emission standards before being released into the atmosphere.

[0033] However, during the exhaust gas conveying process, silica powder gradually adheres to the inner wall of the pipe, forming dust, and the dust thickness increases over time. When the dust reaches a certain thickness, it weakens the exhaust gas conveying capacity and may even cause pipe blockage, affecting normal production. To ensure the exhaust gas conveying capacity, the commonly used method is to manually disassemble the pipe periodically and use a cleaning brush to remove the dust from the inner wall.

[0034] However, manual pipe dismantling has certain drawbacks: First, the cleaning work can only be carried out when the machine is stopped, and the process of dismantling the pipe is tedious and labor-intensive; second, the cleaning operation requires the cooperation of multiple people, resulting in high labor costs; finally, a large amount of dust is generated during the pipe dismantling and cleaning process, which will pollute the equipment and the ground, affecting the production environment and product quality in the workshop.

[0035] In view of this, embodiments of this application disclose a cleaning device and a tailpipe system, which cleans the powder adhering to the inner wall of the pipeline by having a cleaning component extending along the extension direction of the pipeline contact the inner wall of the pipeline, and cleans the powder adhering to the inner wall of the pipeline when the cleaning component rotates, so as to achieve the purpose of cleaning without manually disassembling the pipeline.

[0036] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0037] Please see Figure 1 , Figure 1 This is one of the structural schematic diagrams of the cleaning device 100 provided in the embodiments of this application. The first aspect of this utility model discloses a cleaning device 100, which includes:

[0038] Clean pipe 1. One end of clean pipe 1 is used to connect to exhaust gas pretreatment equipment 200, and the other end of clean pipe 1 is used to connect to exhaust gas treatment equipment 300.

[0039] Cleaning component 2 is disposed within cleaning pipe 1. Cleaning component 2 includes a cleaning member configured to extend into cleaning pipe 1 and extend along the interior of cleaning pipe 1. Cleaning component 2 is capable of contacting the inner surface of cleaning pipe 1.

[0040] The driving component 3 is connected to the cleaning component 2. The driving component 3 is used to drive the cleaning component 2 to rotate circumferentially along the cleaning pipeline 1 so that the cleaning component 2 cleans the inner surface of the cleaning pipeline 1.

[0041] One end of the cleaning pipeline 1 is connected to the exhaust gas pretreatment equipment 200, and the other end is connected to the exhaust gas treatment equipment 300, thus establishing a complete channel for exhaust gas transportation and treatment. The cleaning pipeline 1 ensures that the exhaust gas can pass through the pretreatment and deep treatment stages sequentially from the source, maintaining the continuity and stability of the exhaust gas treatment process and preventing exhaust gas accumulation due to poor pipeline connection, which would affect the normal production environment of the workshop and the operation of the subsequent exhaust gas treatment equipment 300.

[0042] Optionally, the cleaning pipeline 1 can be flexibly designed in terms of path and length according to the actual layout of the workshop to adapt to different production environment space requirements. At the same time, the material and diameter of the cleaning pipeline 1 can also be optimized based on factors such as exhaust gas flow rate, pressure and the amount of silica powder generated, to ensure that the cleaning pipeline 1 maintains good conveying performance and structural integrity during long-term use.

[0043] Cleaning component 2 is used to clean the inner wall of the pipeline. The cleaning element in cleaning component 2 is configured to extend into and along the interior of the cleaning pipeline 1, and to contact the inner surface of the pipeline 1. Specifically, during contact with dust, the cleaning element, relying on its surface material and shape, exerts friction, scraping, or squeezing forces on the silica powder and other contaminants adhering to the pipeline wall, peeling these dust particles off the inner wall of the cleaning pipeline 1, thereby restoring the smoothness of the inner wall of the cleaning pipeline 1 and improving the exhaust gas conveying capacity. For example, the cleaning element may have a relatively rough surface, thereby using friction and squeezing on the surface of the cleaning element to remove silica powder and other contaminants; or the cleaning element may have a larger cleaning area when moving due to its curved or bent shape, enabling it to clean a larger area of ​​the pipeline inner wall, and generating elastic deformation adapted to the shape of the pipeline through its curved or bent shape.

[0044] It is understandable that the cleaning component must allow powder and gas inside the cleaning pipe 1 to pass through the cleaning pipe 1 while cleaning, in order to ensure the unobstructed flow of the cleaning pipe 1 during the cleaning process. At the same time, the cleaning component can fully cover a large area of ​​the inner wall of the pipe during operation, reaching various locations inside the pipe, including some relatively hidden corners, thereby effectively removing dirt such as silica powder adhering to the pipe wall and ensuring the unobstructed flow of exhaust gas.

[0045] Optionally, the cleaning component may be a cleaning brush extending inside the cleaning conduit 1, a spring extending inside the cleaning conduit 1, or a cleaning sponge extending inside the cleaning conduit 1, etc.

[0046] The driving component 3 is connected to the cleaning assembly 2 and is used to drive the cleaning assembly 2 to rotate circumferentially along the cleaning pipe 1. This driving method enables the cleaning assembly 2 to rotate continuously and evenly, allowing the cleaning component to rub against the inner surface of the pipe in all directions. Compared with linear motion in one direction, circumferential rotation can more thoroughly remove dust adhering in different directions, improve cleaning efficiency, reduce cleaning dead spots, and ensure the reliability of the cleaning effect. At the same time, the setting of the driving component 3 also reduces the need for manual intervention, reduces labor intensity and the impact of human factors on the cleaning effect, and improves the reliability and consistency of the cleaning work.

[0047] Optionally, the driving component 3 can be a DC motor, an AC motor, or a pneumatic motor, etc., and this application embodiment does not limit this.

[0048] Thus, the cleaning device 100 provided in this embodiment drives the cleaning assembly 2 to rotate inside the cleaning pipeline 1 and contact the inner wall of the cleaning pipeline 1 via the driving component 3. This allows for efficient cleaning of dust from the inner wall of the pipeline 1 without affecting the normal exhaust gas transport and treatment process. Unlike traditional methods, it eliminates the need for frequent shutdowns and large-scale pipeline disassembly, reducing labor and maintenance time costs. It also reduces dust pollution caused by cleaning operations, helps maintain a good environment in the cleanroom, ensures the continuity and stability of production, and improves the operating efficiency and maintenance convenience of the exhaust gas treatment system in the solar cell production workshop.

[0049] Please see Figure 1 In some embodiments, the cleaning component 2 includes a helical spring 21, the outer peripheral surface of which can contact the inner surface of the cleaning pipe 1 so that the outer peripheral surface of the helical spring 21 can clean the inner surface of the cleaning pipe 1.

[0050] Specifically, the helical spring 21 is an elastic element made of an elastic material (such as high-carbon steel, stainless steel, or alloy steel) wound into a spiral shape, mainly composed of a cylindrical or conical spiral body formed by uniformly wound metal wire. When the helical spring 21 moves inside the cleaning pipe 1, the spiral structure on the outer circumference of the helical spring 21 will form a continuous friction and scraping action with the pipe wall, which helps to peel off dirt such as silica powder adhering to the pipe wall.

[0051] The elastic properties of the helical spring 21 allow it to flexibly adapt to changes within the cleaning pipe 1. When the helical spring 21 moves within the cleaning pipe 1, its outer circumference adheres to the pipe wall due to elasticity. Because the helical spring 21 is elastic, the contact between it and the pipe wall is not a rigid, straight line, but can be adjusted to a certain extent according to the shape of the pipe wall and the thickness of the dust.

[0052] Understandably, regardless of whether it's a protrusion, depression, or irregular dust distribution on the inner wall of cleaning pipe 1, the helical spring 21 can flexibly adhere to the cleaning pipe 1, ensuring thorough cleaning without any blind spots. During the cleaning process, the elasticity of the helical spring 21 can also buffer the impact force between itself and the pipe wall of cleaning pipe 1, reducing potential damage to the pipe wall.

[0053] The helical spring 21 naturally possesses the function of stirring and agitating when rotating or moving. As the helical spring 21 rotates or advances within the cleaning pipe 1, its helical structure generates a helical thrust on the surrounding dust. This thrust not only peels the dust from the pipe wall of the cleaning pipe 1 but also, to a certain extent, breaks the dust into smaller particles, making it easier for the airflow to carry it away or expel it from the pipe. Simultaneously, the helical structure produces a "stirring" effect during movement, making it difficult for dust to form a stable adhesion layer on the pipe wall, further improving cleaning efficiency.

[0054] In addition, the movement of the helical spring 21 within the cleaning pipe 1 is not a completely regular linear or rotational motion, but may be affected by factors such as the thickness of the dust and the airflow speed within the cleaning pipe 1, resulting in a certain degree of oscillation or deviation.

[0055] Understandably, the more free-moving trajectory allows the spring to cover a larger area of ​​the pipe wall, avoiding blind spots that might be left by traditional linear or fixed-track cleaning tools. Each swing or shift of the helical spring 21 can reach previously unattended areas, resulting in a more thorough cleaning. The irregular movement also increases the complexity of the relative motion between the helical spring 21 and the dust, making the frictional and shearing forces acting on the dust more diverse, thus more effectively breaking down the dust's adhesion and peeling it off the pipe wall.

[0056] Please see Figure 1 In some embodiments, the helical spring 21 includes a plurality of helical segments 211 and a plurality of flexible connecting segments 212, the flexible connecting segments 212 and the helical segments 211 being arranged alternately and connected to each other, the flexible connecting segments 212 being configured such that adjacent helical segments 211 connected to each other have an adjustable direction of extension.

[0057] The helical spring 21 consists of multiple helical segments 211 and a flexible connecting segment 212, and the flexible connecting segment 212 allows the extension direction of two adjacent helical segments 211 to be adjusted. This allows the entire helical spring 21 to better adapt to the irregular shape and complex structure of the inner wall of the cleaning pipe 1. When the helical spring 21 encounters a curved cleaning pipe 1, the flexible connecting segment 212 makes it easier to adjust the direction of the two adjacent helical segments 211 connected to follow the curve of the cleaning pipe for more comprehensive cleaning.

[0058] During the cleaning process, when encountering bends, diameter changes, or obstacles in the cleaning pipeline 1, the helical spring 21 can flexibly pass through these complex parts by adjusting the extension direction of each helical segment 211, ensuring that the cleaning work is not limited by the shape of the cleaning pipeline 1, and improving the accessibility and adaptability of the cleaning.

[0059] Furthermore, each spiral segment 211, under the action of the flexible connecting segment 212, can clean the inner wall of the cleaning pipe 1 from different directions. When the spiral spring 21 moves inside the cleaning pipe 1, adjacent spiral segments 211 extend in different directions, which can more comprehensively cover all areas of the inner wall of the cleaning pipe 1, including some hard-to-reach corners and sides. This multi-angle cleaning method can more effectively remove dust, improve cleaning efficiency, and make the inner wall of the cleaning pipe 1 cleaner.

[0060] In addition, since each spiral segment 211 can extend and clean in different directions, the spiral spring 21 can distribute the cleaning force more evenly when it moves in the cleaning pipe 1, so that the cleaning effect on each part of the inner wall of the cleaning pipe 1 is more balanced, avoiding the situation that some areas are over-cleaned while some areas are under-cleaned, thereby achieving a more uniform and consistent cleaning effect.

[0061] Please see Figure 1 In some embodiments, the cleaning pipeline 1 includes multiple pipeline segments 11 connected end to end, the extension directions of two adjacent pipeline segments 11 intersect, and each pipeline segment 11 is provided with at least two spiral segments 211.

[0062] The pipeline 1 is composed of multiple pipeline segments 11 that are connected end to end and intersect in their extension directions, enabling the entire pipeline to adapt to complex workshop layouts and equipment arrangements. The intersecting extension directions of adjacent pipeline segments 11 can form bends or deflections to avoid obstacles or connect equipment in different locations.

[0063] Each pipe section 11 is equipped with at least two spiral sections 211. The spiral section 211 and the flexible connection section 212 of the spiral spring 21 can flexibly adjust their extension direction and shape as the pipe bends and changes direction, so as to better fit the shape changes of the inner wall of the pipe and improve the accessibility and adaptability of cleaning.

[0064] When cleaning pipeline 1, which has multiple interconnected pipeline segments 11 to accommodate workshop layout and equipment arrangement, the at least two spiral segments 211 inside each pipeline segment 11 enable the spiral spring 21 to fully cover all areas of the pipeline's inner wall during cleaning, including the inside and outside of bends and locations prone to dead angles such as the connection points of adjacent pipeline segments 11. The flexible connecting segment 212 of the spiral spring 21 allows the spiral segment 211 to be flexibly adjusted in different directions, enabling the spiral spring 21 to penetrate into every corner of complex structures and reduce dust residue.

[0065] Since each pipe section 11 contains at least two helical segments 211, the movement of the helical spring 21 within the pipe allows for a more even distribution of cleaning force. The intersecting extension directions of adjacent pipe sections 11 enable the cleaning force to be transmitted and acted upon in different directions, preventing over-cleaning in some areas and under-cleaning in others, thus achieving a more uniform and consistent cleaning effect.

[0066] Please see Figure 1 In some embodiments, the outer diameter of the helical spring 21 is less than 20% of the diameter of the cleaning pipe 1, resulting in a certain spatial gap between the helical spring 21 and the pipe wall when the helical spring 21 moves within the cleaning pipe 1. This provides sufficient range of motion for the rotation and propulsion of the helical spring 21, avoiding excessive frictional resistance caused by excessive tight contact between the helical spring 21 and the pipe wall. This ensures that the cleaning assembly 2 can move smoothly within the pipe and efficiently clean various parts of the pipe wall according to the predetermined cleaning path.

[0067] When the outer diameter of the helical spring 21 is within this ratio range to the diameter of the cleaning pipe 1, during the spring rotation cleaning process, its outer circumference can generate sufficient friction force against the pipe wall to remove dust, and will not cause the cleaning force to be too concentrated due to excessive contact, thereby damaging the pipe wall or causing the helical spring 21 itself to undergo irreversible deformation due to excessive force.

[0068] At the same time, the appropriate space gap helps the cleaned dust to detach smoothly from the gap between the spiral spring 21 and the pipe wall and be carried away by the airflow, preventing the dust from re-adhering to the pipe wall or spiral spring 21 during the cleaning process, thereby optimizing the cleaning effect.

[0069] Furthermore, since the outer diameter of the helical spring 21 is relatively small compared to the diameter of the cleaning pipe 1, there is a certain space between the helical spring 21 and the pipe wall inside the cleaning pipe 1. This makes it less likely for the helical spring 21 to get stuck or blocked during rotation or advancement, even if it encounters dust inside the cleaning pipe 1, ensuring the flow of gas and dust inside the cleaning pipe 1 and preventing the helical spring 21 from clogging the cleaning pipe 1.

[0070] Please see Figure 2 , Figure 2 yes Figure 1 In the enlarged view at point A, in some embodiments, the drive component 3 further includes a drive shaft 31, a portion of which extends into the cleaning pipe 1 to connect the drive shaft 31 to the cleaning assembly 2; the cleaning assembly 2 also includes a connecting rod 22, a helical spring 21 sleeved on the outside of the connecting rod 22, and the connecting rod 22 is connected to the drive shaft 31 to drive the connecting rod 22 to rotate.

[0071] The drive unit 3 also includes a drive shaft 31, a portion of which extends into the cleaning pipe 1. The cleaning assembly 2 also includes a connecting rod 22, with a coil spring 21 sleeved on the outside of the connecting rod 22 for easy disassembly and maintenance. Since the connecting rod 22 is connected to the drive shaft 31, maintenance of the coil spring 21 is simply required by removing it from the connecting rod 22, eliminating the need for extensive disassembly of the drive shaft 31 and other components. This structure simplifies maintenance operations, allowing maintenance personnel to more quickly inspect, clean, or replace the coil spring 21, improving convenience and efficiency, reducing equipment downtime, and lowering maintenance costs.

[0072] Specifically, the connecting rod 22 is connected to the drive shaft 31 via the coupling 6 and fixed by the bearing 7, so that when the drive shaft 31 drives the connecting rod 22 to rotate, the power transmission is direct and efficient. The coupling 6 can effectively compensate for the misalignment between shafts, ensure smooth power transmission, avoid power transmission interruption or instability due to shaft misalignment, and improve the operational reliability of the cleaning device 100.

[0073] Optionally, the connecting rod 22 can be fixed to the inner wall of the cleaning pipe 1 by a bearing 7. The bearing 7 enhances the connection stability. When the helical spring 21 rotates, the bearing 7 can withstand radial and axial forces, reducing the vibration and sway of the drive shaft 31 and the connecting rod 22, thus stabilizing the inner wall of the cleaning pipe 1 and improving the cleaning effect. The coupling 6 and the bearing 7 work together to reduce the risk of damage to the drive shaft 31 and the connecting rod 22, reduce friction, extend the service life of components, and reduce maintenance costs.

[0074] Please see Figure 1 In some embodiments, the cleaning device 100 further includes a control component 4, which is electrically connected to the drive component 3 and is used to control the start and stop time of the drive component 3 and / or adjust the rotation speed of the drive component 3.

[0075] The introduction of control component 4 enables precise control of drive component 3, allowing for the setting of start / stop times and adjustment of rotation speed according to actual needs. This automated control method reduces manual intervention and improves the reliability and consistency of cleaning operations.

[0076] By adjusting the rotation speed of the drive component 3 using the control component 4, an appropriate cleaning speed can be adopted for different dust levels and material characteristics of different pipe sections 11, thereby optimizing the cleaning effect. In areas with thicker dust or difficult-to-clean areas, the rotation speed can be increased to enhance the cleaning force; while in areas with lighter dust or more fragile pipe walls, the rotation speed can be reduced to protect the pipe walls, achieving a more precise and efficient cleaning.

[0077] Optionally, the control component 4 can be set to start the drive component 3 every hour for a predetermined time to perform cleaning work. In the solar cell production workshop, exhaust gas emission is a continuous process. This timed, short-cycle cleaning method can save energy and clean the dust inside the pipes in a timely manner without affecting normal production, preventing excessive dust accumulation.

[0078] Optionally, a dust monitoring sensor can be installed inside the cleaning pipe to monitor the dust generation rate in real time. If the dust generation rate is high, the control component 4 can automatically shorten the cleaning interval, such as adjusting it from cleaning once per hour to cleaning once every half hour.

[0079] Please see Figure 3 and Figure 4 , Figure 3 This is the second schematic diagram of the cleaning device 100 provided in the embodiments of this application. Figure 4 yes Figure 3 A partial enlarged view at point B. In some embodiments, the cleaning pipeline 1 is connected to the exhaust gas treatment device 300 via the tail exhaust pipeline 5. The tail exhaust pipeline 5 includes a first tail exhaust pipeline 51 and a second tail exhaust pipeline 52. The first tail exhaust pipeline 51 is provided with a first tail exhaust valve 511, which is used to control the opening and closing of the first tail exhaust pipeline 51. The second tail exhaust pipeline 52 is provided with a second tail exhaust valve 521, which is used to control the opening and closing of the second tail exhaust pipeline 52.

[0080] The first tail gas pipeline 51 and the second tail gas pipeline 52 enhance the reliability and stability of the cleaning device 100. When one pipeline fails or needs maintenance, the other pipeline can quickly take over the work, ensuring that the exhaust gas treatment process is uninterrupted and that the workshop production is operating normally.

[0081] Meanwhile, this configuration enhances the flexibility and adaptability of the cleaning device 100, allowing for flexible switching of the tail gas pipeline 5 based on exhaust gas flow, pressure, and pipeline operating conditions, effectively addressing various operating conditions during production. Furthermore, the mutually redundant tail gas pipelines 5 facilitate maintenance and management. Idle tail gas pipelines 5 can be inspected, cleaned, or have components replaced without affecting production, extending the service life of the cleaning device 100 and reducing maintenance costs. If an increased risk of blockage is detected in a particular tail gas pipeline 5, the problematic pipeline can be switched and cleaned promptly.

[0082] In some embodiments, the cleaning device 100 further includes a negative pressure generator (not shown in the figure), which is connected to the cleaning pipeline 1 and is used to create a negative pressure in the cleaning pipeline 1.

[0083] It is understandable that negative pressure generators can effectively enhance dust removal. The negative pressure generated within the cleaning pipe 1 promotes the airflow carrying dust particles toward the cleaning component 2, making it easier for the dust to separate from the pipe wall and be removed by the cleaning component 2.

[0084] Meanwhile, negative pressure helps to promptly remove dust and debris generated during the cleaning process, preventing secondary adhesion and improving cleaning efficiency. Furthermore, the formation of negative pressure reduces dust leakage during cleaning, lowering the risk of contamination to the cleaning equipment and the environment, and helping to maintain a healthy environment in the cleanroom.

[0085] In addition, the negative pressure generating component and the driving component 3 work together to achieve simultaneous cleaning and suction, optimize the cleaning process, shorten the cleaning time, and make the entire cleaning device 100 operate more efficiently and stably, further improving the maintenance efficiency and reliability of the cleaning device 100.

[0086] The second aspect of this utility model discloses an exhaust system, which includes: an exhaust gas pretreatment device 200; a cleaning device 100 of the first aspect, one end of the cleaning pipe 1 of the cleaning device 100 being connected to the exhaust gas pretreatment device 200; and an exhaust gas treatment device 300, which is connected to the other end of the cleaning pipe 1.

[0087] Since the exhaust system provided in this application includes the cleaning device 100 provided in the first aspect of this application, the exhaust system has the beneficial effects of any of the cleaning devices 100 described above, which will not be repeated here.

[0088] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
