For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.

[0044] In addition, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0046] As mentioned in the background technology, since the gas after combustion in the pretreatment equipment contains a large amount of dust, for example, silica dust, part of the dust will be deposited on the pipe wall of the exhaust gas conveying pipe during the process of conveying gas. As the dust deposited on the pipe wall increases, the cross-sectional area of ​​the exhaust gas conveying pipe will be reduced, thereby reducing the conveying capacity of the exhaust gas conveying pipe.

[0047] In order to solve the above-mentioned problems, the present application provides an exhaust gas conveying pipeline and an exhaust gas treatment device, and a delivery structure and a recovery structure are arranged on the pipeline body of the exhaust gas conveying pipeline, the delivery structure is used to deliver the cleaning structure into the pipeline body, and the recovery structure is used to recover the cleaning structure that has completed cleaning the inner wall of the pipeline body, so as to utilize the cleaning structure to clean the inner wall of the pipeline body so that the dust deposited on the pipe wall can be separated from the inner wall of the pipeline body and fall into the pipeline body, so that the dust deposited on the pipe wall can be carried out of the exhaust gas conveying pipeline by the gas flowing in the pipeline body, so as to realize timely cleaning of the dust deposited on the pipe wall, and to avoid as much as possible the situation where too much dust is deposited on the pipe wall, resulting in a reduction in the cross-sectional area of ​​the exhaust gas conveying pipeline, thereby resulting in a reduction in the conveying capacity of the exhaust gas conveying pipeline.

[0048] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.

[0049] See also Figure 1The present embodiment provides an exhaust gas conveying pipeline 1, which includes a pipeline body 100, a cleaning structure 200, a delivery structure 300 and a recovery structure 400. The cleaning structure 200 is used to clean the inner wall of the pipeline body 100; the delivery structure 300 is arranged on the pipeline body 100, and the delivery structure 300 is used to deliver the cleaning structure 200 into the pipeline body 100; the collection structure is arranged on the pipeline body 100, and the recovery structure 400 is used to recover the cleaning structure 200 that has completed cleaning the inner wall of the pipeline body 100.

[0050] The delivery structure 300 can deliver the cleaning structure 200 automatically or manually, and the recovery structure 400 can recover the cleaning structure 200 automatically or manually, which is not limited here.

[0051] It should be noted that the above-mentioned pipeline body 100 can be a straight pipeline or a curved pipeline, which is not limited here.

[0052] Since the pipeline body 100 is provided with a delivery structure 300 and a recovery structure 400, the delivery structure 300 is used to deliver the cleaning structure 200 into the pipeline body 100 so as to use the cleaning structure 200 to clean the inner wall of the pipeline body 100, and the recovery structure 400 is used to recover the cleaning structure 200 that has completed the cleaning of the inner wall of the pipeline body 100. Therefore, in the process of the pipeline body 100 of the exhaust gas delivery pipeline 1 transporting the gas containing dust 10, if part of the dust 10 in the gas is deposited on the pipe wall of the pipeline body 100, the delivery structure 300 can deliver the cleaning structure 200 into the pipeline body 100 so as to use the cleaning structure 200 to clean the inner wall of the pipeline body 100, so that the dust 10 deposited on the pipe wall can be separated from the inner wall of the pipeline body 100 and fall into the pipeline body 100, thereby making The dust 10 deposited on the pipe wall can be carried out of the exhaust gas conveying pipe 1 by the gas flowing in the pipe body 100, so as to realize timely cleaning of the dust 10 deposited on the pipe wall, and avoid as much as possible the situation that too much dust 10 is deposited on the pipe wall, which leads to a reduction in the cross-sectional area of ​​the exhaust gas conveying pipe 1, thereby causing a reduction in the conveying capacity of the exhaust gas conveying pipe 1, and the cleaning structure 200 after cleaning the inner wall of the pipe body 100 can be recovered by the recovery structure 400, so that the staff can take out the cleaning structure 200 for cleaning through the recovery structure 400, and avoid as much as possible the deposition of too much dust 10 on the surface of the cleaning structure 200, which leads to a reduction in the cleaning ability, thereby preventing as much as possible the cleaning effect of the cleaning structure 200 on the pipe wall from being deteriorated, and further avoiding the situation that the conveying capacity of the exhaust gas conveying pipe 1 is reduced.

[0053] In addition, compared with the related art in which the exhaust gas conveying pipeline 1 is disassembled for manual cleaning, the present embodiment uses the delivery structure 300 to deliver the cleaning structure 200 into the interior of the pipeline body 100 to clean the dust 10 deposited on the inner wall of the pipeline body 100, so that the pipe wall can be cleaned during the process of gas delivery in the exhaust gas conveying pipeline 1, thereby avoiding the need to disassemble the exhaust gas conveying pipeline 1 for manual cleaning as much as possible, which not only reduces the labor intensity of the workers, but also avoids the gas escaping into the external environment when the exhaust gas conveying pipeline 1 is disassembled, causing an impact on the health of the workers or triggering the special gas detector, resulting in the shutdown of the production equipment, thereby improving the safety of the production process.

[0054] In one possible embodiment, see Figure 3 , Figure 4 as well as Figure 5 The cleaning structure 200 has a cleaning brush 210 on its surface.

[0055] The cleaning brush 210 may be a flexible brush or a rigid brush, which is not limited here.

[0056] Since the dust 10 deposited on the inner wall of the pipe body 100 is usually composed of a number of fine particles, this embodiment arranges a cleaning brush on the surface of the cleaning structure 200. The cleaning brush can adapt to different surfaces and can clean fine dust. When the cleaning structure 200 is used to clean the inner wall of the pipe body 100, the cleaning brush 210 can specifically clean the dust 10 deposited on the inner wall of the pipe body 100, thereby improving the cleaning effect of the cleaning structure 200 on the inner wall of the pipe body 100.

[0057] In a possible embodiment, the cleaning brush 210 is an elastic brush.

[0058] The material of the elastic brush includes but is not limited to natural hair, artificial fiber, rubber, sponge and the like.

[0059] Since the cleaning brush 210 is an elastic brush, when the cleaning structure 200 cleans the pipe wall of the pipe body 100, the cleaning brush 210 will not have a rigid contact with the pipe wall of the cleaning pipe, thereby avoiding the cleaning structure 200 from causing damage to the pipe wall of the pipe body 100. In addition, since the elastic brush has resilience, the cleaning structure 200 can clean most of the surface of the inner wall as much as possible, thereby improving the cleaning effect. In addition, compared with the related art in which the cleaning structure 200 and the inner wall of the pipe body 100 are directly rubbed to achieve cleaning, the elastic brush in this embodiment enables the cleaning structure 200 to impact and bounce inside the pipe body 100 to break up the dust 10 deposited on the inner wall, thereby achieving cleaning. Since in this process, the cleaning structure 200 does not have direct friction with the inner wall of the pipe body 100, the generation of static electricity is reduced as much as possible, so as to ensure the safety of the exhaust gas delivery pipeline 1 when transporting gas as much as possible.

[0060] In one possible embodiment, see Figure 3 , Figure 4 as well as Figure 5 , the cleaning structure 200 is an elliptical structure.

[0061] The cleaning structure 200 may be a solid structure or a hollow structure, which is not limited here.

[0062] By making the cleaning structure 200 an elliptical structure, the shape of the cleaning structure 200 is relatively stable and is not easily deformed during the cleaning process of the pipe wall. At the same time, the surface of the cleaning structure 200 can be free of edges and corners. When the cleaning structure 200 rolls or moves on the inner wall of the pipe body 100, the friction force generated between the cleaning structure 200 and the pipe wall is small, thereby avoiding as much as possible the cleaning structure 200 from damaging the pipe wall during the cleaning process.

[0063] Of course, the shape of the cleaning structure 200 is not limited thereto, and the cleaning structure 200 may also be a spherical structure, a conical structure, etc.

[0064] In one possible embodiment, see Figure 3 , Figure 4 as well as Figure 5 The cleaning structure 200 also includes a supporting structure 220 , which includes a first web 221 and a second web 222 arranged crosswise, wherein the length of the first web 221 is greater than the length of the second web 222 ; the cleaning brush 210 is wrapped around the outer periphery of the supporting structure 220 .

[0065] By making the supporting structure 220 include a first web 221 and a second web 222 that are cross-arranged, the length of the first web 221 is greater than the length of the second web 222, and the cleaning brush 210 is covered on the outer periphery of the supporting structure 220, so that the first web 221 and the second web 222 that are cross-arranged are utilized as the supporting structure 220 of the cleaning brush 210, so that the cleaning structure 200 is an elliptical structure with a hollow interior. Compared with the solid structure of the cleaning structure 200 in the related art, the interior of the cleaning structure 200 in this embodiment is a hollow structure, so that the self-weight of the cleaning structure 200 is lighter, so that when the cleaning structure 200 cleans the inner wall inside the pipe body 100, if the flow rate of the gas on the inner wall of the pipe reaches a certain value, the cleaning structure 200 can move inside the pipe body 100 along with the flow of the gas.

[0066] For example, the first web 221 and the second web 222 are plastic sheets made of PP, RPP, CPVC, PVDF or PVC, and the thickness of the first web 221 and the second web 222 is less than 1.5 mm, so that the cleaning structure 200 can be pushed by the gas inside the pipe body 100 and continuously roll inside the pipe body 100 when the gas flow rate is greater than or equal to 10 m / s, and hit the inner wall to clean the inner wall.

[0067] In another possible embodiment, the support structure 220 is a hollow shell.

[0068] In one possible embodiment, see Figure 1 The tail gas delivery pipeline 1 is bent, thereby reducing the space required for the tail gas delivery pipeline 1 to achieve reasonable utilization of the internal space of the production workshop.

[0069] In a possible embodiment, the pipe body 100 is made of metal, so that the pipe body 100 can release static electricity generated when the cleaning structure 200 cleans the pipe wall.

[0070] In one possible embodiment, see Figure 2 The delivery structure 300 includes a delivery chamber 301 and a first valve 302 for controlling the opening or closing of the delivery chamber 301. A cleaning structure 200 is arranged in the delivery chamber 301. When the first valve 302 is opened, the delivery chamber 301 is connected with the interior of the pipeline body 100 so that the cleaning structure 200 in the delivery chamber 301 enters the pipeline body 100.

[0071] The delivery chamber 301 may include only one cleaning structure 200 or multiple cleaning structures 200, which is not limited here.

[0072] It should be noted that the closing and opening of the first valve 302 can be achieved through manual operation or automatic control, which is not limited here.

[0073] Since the delivery structure 300 includes a delivery chamber 301 and a first valve 302 for controlling the opening or closing of the delivery chamber 301, a cleaning structure 200 is arranged in the delivery chamber 301. When the first valve 302 is opened, the delivery chamber 301 is communicated with the interior of the pipeline body 100. Therefore, when the dust 10 deposited on the pipe wall of the pipeline body 100 reaches a certain amount, the first valve 302 is opened to make the delivery chamber 301 communicate with the interior of the pipeline body 100, so that the cleaning structure 200 in the delivery chamber 301 can enter the interior of the pipeline body 100 to clean the inner wall of the pipeline body 100. Compared with the related art in which the delivery structure 300 is used without setting the delivery chamber 301, the delivery chamber 301 is connected with the interior of the pipeline body 100. 01 and a first valve 302 for controlling the opening or closing of the delivery chamber 301. In this embodiment, by setting the delivery chamber 301 and the first valve 302 for controlling the opening or closing of the delivery chamber 301, when it is necessary to drop the cleaning structure 200 into the pipeline body 100, the first valve 302 can be used to control the delivery chamber 301 to open, so that the cleaning structure 200 enters the interior of the pipeline body 100 to clean the dust 10 on the pipe wall of the pipeline body 100, and when the cleaning structure enters the interior of the pipeline body 100 from the delivery chamber 301, the first valve 302 is closed, so as to avoid the gas in the pipeline body 100 from escaping into the delivery chamber 301 and the external environment as much as possible.

[0074] In one possible embodiment, see Figure 2 The delivery structure 300 is a delivery bucket with an opening, and the interior of the delivery bucket constitutes a delivery chamber 301. The delivery structure 300 also includes a first cover body 303 movably arranged at the opening of the delivery bucket. When the first valve 302 is opened, the first cover body 303 is used to close the opening of the delivery bucket to isolate the delivery chamber 301 from the external environment to prevent gas escape.

[0075] For example, the first cover body 303 is locked at the opening of the delivery bucket by a hasp lock. When the cleaning structure 200 needs to be placed in the delivery chamber 301, the unlocking hasp is simply pulled to release the lock between the first cover body 303 and the delivery bucket, and then the first cover body 303 is moved away from the opening of the delivery bucket, so that the cleaning structure 200 can be placed in the delivery chamber 301. When the first valve 302 needs to be opened to allow the cleaning structure 200 to enter the interior of the pipeline body 100, the first cover body 303 is locked at the opening of the delivery bucket by using the hasp lock to isolate the delivery chamber 301 from the external environment and prevent gas from escaping.

[0076] Of course, the method of locking the first cover body 303 to the opening of the delivery bucket is not limited to this. For example, an external thread is set on the first cover body 303, and an internal thread matching the external thread on the first cover body 303 is set at the opening of the delivery bucket, so that the first cover body 303 can be locked to the opening of the delivery bucket through the threaded structure.

[0077] In one possible embodiment, see Figure 2 The recovery structure 400 includes a recovery chamber 401 and a second valve 402 for controlling the opening or closing of the recovery chamber 401. When the second valve 402 is opened, the recovery chamber 401 is connected to the interior of the pipeline body 100 so that the cleaning structure 200 inside the pipeline body 100 enters the recovery chamber 401.

[0078] It should be noted that the closing and opening of the second valve 402 can be achieved through manual operation or automatic control, which is not limited here.

[0079] Since the recovery structure 400 includes a recovery chamber 401 and a second valve 402 for controlling the opening or closing of the recovery chamber 401, a cleaning structure 200 is arranged in the recovery chamber 401. When the second valve 402 is opened, the recovery chamber 401 is communicated with the interior of the pipeline body 100. Therefore, when it is necessary to recover the cleaning structure 200 in the pipeline body 100, the second valve 402 is opened to make the recovery chamber 401 communicate with the interior of the pipeline body 100, so that the cleaning structure 200 in the pipeline body 100 can enter the recovery chamber 401. Compared with the related art in which the recovery structure 400 is used without setting the recovery chamber 401 and the second valve 402 for controlling the opening or closing of the recovery chamber 401, the recovery chamber 401 is connected with the interior of the pipeline body 100. Second valve 402. In this embodiment, by setting a recovery chamber 401 and a second valve 402 for controlling the opening or closing of the recovery chamber 401, when it is necessary to recover the cleaning structure 200 in the pipeline body 100, the second valve 402 can be used to control the opening of the recovery chamber 401, so that the cleaning structure 200 in the pipeline body 100 can enter the recovery chamber 401, and after completing the recovery of the cleaning structure 200 in the pipeline body 100, the second valve 402 is closed, thereby isolating the recovery chamber 401 from the interior of the pipeline body 100. On the one hand, it can prevent the gas in the pipeline body 100 from escaping into the recovery chamber 401 and the external environment as much as possible.

[0080] In one possible embodiment, see Figure 2 The recovery structure 400 is a recovery barrel with an opening, and the interior of the recovery barrel constitutes a recovery chamber 401. The recovery structure 400 also includes a second cover body 403 movably arranged at the opening of the recovery barrel. When the second valve 402 is opened, the second cover body 403 is used to close the opening of the recovery barrel to isolate the recovery chamber 401 from the external environment to prevent gas escape.

[0081] For example, the second cover body 403 is locked to the opening of the recovery barrel by a hasp lock. When the cleaning structure 200 needs to enter the recovery chamber 401, the second cover body 403 is locked to the opening of the recovery barrel by using the hasp lock to isolate the recovery chamber 401 from the external environment and prevent gas from escaping. After the cleaning structure 200 enters the recovery chamber 401, it is only necessary to pull the unlocking buckle to release the lock between the second cover body 403 and the recovery barrel, and then move the second cover body 403 away from the opening of the recovery barrel, so that the cleaning structure 200 in the recovery chamber 401 can be taken out for cleaning for reuse.

[0082] Of course, the method of locking the second cover body 403 to the opening of the recycling bin is not limited to this. For example, an external thread is set on the second cover body 403, and an internal thread matching the external thread on the second cover body 403 is set at the opening of the recycling bin, so that the second cover body 403 can be locked to the opening of the recycling bin through the threaded structure.

[0083] In one possible embodiment, see Figure 1 and Figure 2 The pipeline body 100 includes an air inlet end 101 and an air outlet end 102 , the recovery structure 400 is disposed close to the air inlet end 101 , and the recovery structure 400 is disposed close to the air outlet end 102 .

[0084] By arranging the delivery structure 300 close to the air inlet end 101 and the recovery structure 400 close to the air outlet end 102, on the one hand, compared with the related art in which the delivery structure 300 or the recovery structure 400 is arranged close to the middle position of the pipeline body 100, the cleaning structure 200 in this embodiment can be delivered into the interior of the pipeline body 100 by the delivery structure 300 at a position close to the air inlet end 101, and recovered by the recovery structure 400 at a position close to the air outlet end 102, so that the cleaning structure can start from a position close to the air inlet end 101 of the pipeline body 100 to clean the inner wall of the pipeline body 100 until a position close to the air outlet end 102 of the pipeline body 100, so that the cleaning structure 200 can clean the pipeline body 100 as much as possible. 0 is cleaned from the air inlet end 101 to the air outlet end 102 of the pipe body 100, so that the cleaning range of the cleaning structure 200 is as large as possible, thereby improving the cleaning effect of the inner wall of the pipe body 100. On the other hand, compared with the related art in which the delivery structure 300 is arranged close to the air outlet end 102 and the recovery structure 400 is arranged close to the air inlet end 101, the movement direction of the structure delivered into the pipe body 100 by the delivery structure 300 in this embodiment is consistent with the flow direction of the gas. Therefore, when the cleaning structure 200 has a light weight, the cleaning structure 200 can be driven forward by the flowing gas, and there is no need to additionally set a driving member for pushing the cleaning structure 200 to move, thereby simplifying the structure of the exhaust gas delivery pipeline 1 and reducing the production cost.

[0085] In a possible embodiment, the outlet end 102 of the exhaust gas delivery pipe 1 is provided with an exhaust device, which is used to extract the gas in the pipe body 100 from the inlet end 101 to the outlet end 102 to speed up the gas delivery rate. At the same time, the cleaning structure 200 can be driven to move from the inlet end 101 toward the outlet end 102 inside the pipe body 100.

[0086] In another possible embodiment, the air inlet end 101 of the exhaust gas delivery pipe 1 is provided with a blowing device, which is used to blow the gas in the pipe body 100 from the air inlet end 101 to the air outlet end 102 to speed up the gas delivery rate. At the same time, the cleaning structure 200 can be driven to move from the air inlet end 101 toward the air outlet end 102 inside the pipe body 100.

[0087] In one possible embodiment, see Figure 2 The exhaust gas delivery pipeline 1 also includes a blocking member 500 disposed in the pipeline body 100 . The blocking member 500 is disposed close to the gas outlet end 102 . The blocking member 500 is used to block the cleaning structure 200 in the pipeline body 100 from leaving the gas outlet end 102 .

[0088] By setting a blocking member 500 at the air outlet end 102, when the cleaning structure 200 moves to the air outlet end 102 in the pipe body 100, it can be automatically intercepted by the blocking member 500, preventing the cleaning structure 200 from leaving the pipe body 100 from the air outlet end 102, thereby causing the cleaning structure 200 to enter other equipment and cause production accidents, thereby improving the safety of the production process.

[0089] In a possible embodiment, the blocking member 500 is a blocking net with a hollow structure, and the shape of the blocking net matches the inner diameter of the pipeline body 100 .

[0090] In a possible embodiment, a push rod brush 600 is also provided on the pipe body 100, which can be extended into the pipe body 100 and clean the blocking net. The brush head of the push rod brush 600 is an arc structure matching the inner diameter of the pipe body 100. By pushing the push rod brush 600, the dust 10 attached to the blocking net or the cleaning structure 200 stuck on the blocking net can be swept down by the push rod brush 600.

[0091] In one possible embodiment, see Figure 2 The blocking net is tilted relative to the axis of the pipe body 100. Compared with the related art in which the blocking net is vertically arranged relative to the axis of the pipe body 100, this embodiment makes the blocking net and the recovery structure 400 tilted relative to the axis of the pipe body 100 so that the cleaning structure 200 can enter the recovery structure 400 under the action of force after a collision with the blocking net, thereby making it easier for the cleaning structure 200 to enter the recovery structure.

[0092] In a possible embodiment, the angle between the barrier net and the axis of the pipeline body 100 is 30°-60°.

[0093] If the angle between the blocking net and the axis of the pipe body 100 is less than 30° or greater than 60°, the interaction force between the cleaning structure 200 and the blocking net may be small after the collision, resulting in the cleaning structure being unable to completely enter the recovery structure 400 under the action of the force. Based on this, in this embodiment, the angle between the blocking net and the axis of the pipe body 100 is 30°-60°, so that after the collision between the cleaning structure 200 and the blocking net, the interaction force between the two is large enough to allow the cleaning structure 200 to completely enter the recovery structure 400 under the action of the force as much as possible.

[0094] In one possible embodiment, see Figure 1 and Figure 2 A guide member 700 is provided between the interior of the pipe body 100 and the recovery structure 400 , and the guide member 700 is used to guide the cleaning structure 200 entering the recovery structure 400 from the pipe body 100 , so that the cleaning structure 200 can smoothly enter the recovery structure 400 under the action of the guide member 700 .

[0095] In one possible embodiment, see Figure 1 and Figure 2 The guide member 700 is a guide pipe, which is arranged parallel to the blocking net. The first end of the guide pipe extends into the interior of the pipe body 100, and the second end is connected to the recovery structure 400. The port of the first end is an oblique opening arranged toward the blocking net. When the cleaning structure 200 hits the blocking net, it will move toward the first end of the guide pipe under the action of the force, thereby entering the first end of the guide pipe, so that the cleaning structure 200 enters the recovery structure 400 through the guide pipe.

[0096] An embodiment of the present application also provides an exhaust gas treatment device, which includes an exhaust gas pretreatment device, an exhaust gas retreatment device and the above-mentioned exhaust gas delivery pipeline 1; the exhaust gas pretreatment device is used to pretreat the gas in the production process; the exhaust gas retreatment device is used to retreat the gas treated by the exhaust gas pretreatment device so that the exhaust gas meets the emission standards; the exhaust gas delivery pipeline 1 is arranged between the exhaust gas pretreatment device and the exhaust gas retreatment device.

[0097] The exhaust gas pretreatment device is connected to the exhaust gas delivery pipeline 1 via a pretreatment exhaust pipe 20 .

[0098] In the production process, for example, in the process of solar cell production, after each round of process is completed, the production machine will discharge the remaining process gas to the tail gas pretreatment equipment for treatment. Through plasma combustion, the special gas contained in the gas is converted into a gas containing silicon dioxide and other substances. The treated gas is then discharged to the gas treatment equipment through the tail gas conveying pipeline 1 for further treatment and discharge into the atmosphere after meeting the standards. However, since the gas after combustion in the pretreatment equipment contains a large amount of dust 10, such as silicon dioxide dust 10, part of the dust 10 will be deposited in the tail gas during the process of conveying the gas in the tail gas conveying pipeline 1. On the pipe wall of the conveying pipe 1, based on this, the pipe body 100 of the exhaust gas conveying pipe 1 in this embodiment is provided with a delivery structure 300 and a recovery structure 400, the delivery structure 300 is used to deliver the cleaning structure 200 into the pipe body 100, so as to use the cleaning structure 200 to clean the inner wall of the pipe body 100, and the recovery structure 400 is used to recover the cleaning structure 200 that has completed the cleaning of the inner wall of the pipe body 100. Therefore, in the process of the pipe body 100 of the exhaust gas conveying pipe 1 transporting the gas containing dust 10, if part of the dust 10 in the gas is deposited on the pipe body 100, the cleaning structure 200 can be recovered. The exhaust gas delivery pipeline 1 is provided with a cleaning structure 200 disposed on the pipe wall of the pipeline body 100, and the delivery structure 300 can deliver the cleaning structure 200 into the pipeline body 100. After the cleaning structure 200 enters the pipeline body 100, the inner wall of the pipeline body 100 is cleaned, so that the dust 10 deposited on the pipe wall is separated from the inner wall of the pipeline body 100 and falls into the pipeline body 100, so that the dust 10 deposited on the pipe wall can be carried out of the exhaust gas delivery pipeline 1 by the gas flowing in the pipeline body 100, so as to realize the timely cleaning of the dust 10 deposited on the pipe wall, and avoid the exhaust gas caused by excessive dust 10 deposited on the pipe wall as much as possible. The cross-sectional area of ​​the conveying pipeline 1 is reduced, which leads to a reduction in the conveying capacity of the exhaust gas conveying pipeline 1. In addition, the cleaning structure 200 can be recovered by the recovery structure 400 after cleaning the inner wall of the pipeline body 100, so that the staff can take out the cleaning structure 200 for cleaning through the recovery structure 400, and avoid as much as possible the deposition of excessive dust 10 on the surface of the cleaning structure 200, which leads to a reduction in the cleaning ability, thereby preventing the cleaning effect of the cleaning structure 200 on the pipe wall from deteriorating as much as possible, and further avoiding the reduction in the conveying capacity of the exhaust gas conveying pipeline 1.

[0099] Among them, the exhaust gas conveying pipeline 1 in the embodiment of the present application can have the same structure as any exhaust gas conveying pipeline 1 in the above embodiments, and can bring the same or similar beneficial effects. Please refer to the description in the above embodiments for details, and the embodiments of the present application will not be repeated here.
