Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, specifically relating to a poly process silane waste gas treatment device. Background Technology

[0002] In the production process of TOPCon batteries, the silane exhaust manifold is a crucial component for transporting silane exhaust gas to the next processing equipment. Due to the characteristics of the production environment, dust from silane combustion easily accumulates inside the manifold. If not cleaned in time, it will affect the exhaust efficiency and reduce the negative pressure of the exhaust pipe, thereby affecting the normal production of battery cells in the workshop.

[0003] The traditional maintenance method involves making a prototype tool (i.e., making a circular plate or other air-blowing device slightly smaller than the main tube), relying on manual labor to drag it back and forth to pull out the dust inside the main tube through contact, and then manually bagging it.

[0004] This method not only consumes a lot of manpower, but also has a long maintenance time, low efficiency, and dust flies everywhere when manually bagging, making it difficult to meet the needs of large-scale production. Utility Model Content

[0005] The purpose of this invention is to provide a polyprocess silane waste gas treatment device to solve the problems mentioned in the background art. The polyprocess silane waste gas treatment device provided by this invention has the advantages of reducing maintenance labor costs, shortening maintenance time, and preventing dust overflow.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a poly process silane waste gas treatment device, including a tailpipe connecting pipe, a first main pipe and a second main pipe, the tailpipe connecting pipe being connected to the first main pipe and the second main pipe respectively through a three-way valve, the first main pipe having a plurality of gas outlet pipes, and gas outlet pipe valves installed on the gas outlet pipes, the second main pipe having the same structure as the first main pipe, and waste gas treatment components being connected to the corresponding gas outlet pipes on the first main pipe and the second main pipe, the waste gas treatment components including a fan.

[0007] To further treat the exhaust gas, the exhaust gas treatment assembly includes a combustion device and a dust removal device. The combustion device is connected to the exhaust pipes on the first main pipe and the second main pipe via branch pipes, and the combustion device is connected to the dust removal device via connecting pipes.

[0008] Furthermore, in this invention, the fan is installed at the rear end of the dust removal device.

[0009] Furthermore, in this utility model, a connecting pipe valve is installed on the connecting pipe.

[0010] To ensure effective treatment of exhaust gases, the combustion device is further equipped with a protective gas inlet pipe and an auxiliary combustion gas inlet pipe.

[0011] To ensure efficient dust removal, the first main pipe is further equipped with several air inlet pipes, each with an air inlet valve.

[0012] To ensure good sealing and rapid switching action, both the outlet and inlet valves are flanged butterfly valves or gate valves.

[0013] Furthermore, in this utility model, the dust removal device is a pulse-jet bag filter.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model is provided with a first mother pipe and a second mother pipe. When the first mother pipe needs maintenance, the exhaust gas is discharged through the second mother pipe, and vice versa. This avoids the maintenance of the mother pipe affecting the exhaust gas discharge and ensures the continuity of TOPCon battery production.

[0016] 2. This utility model uses a fan to generate negative pressure to extract dust from the main pipe that needs maintenance, eliminating the need for tedious dragging and cleaning with tools, reducing manual operation and improving maintenance efficiency.

[0017] 3. This utility model treats exhaust gas through a combustion device and a dust removal device, which not only meets the daily exhaust gas treatment needs, but also treats residual exhaust gas and cleaned dust during maintenance, reducing or avoiding dust overflow during maintenance.

[0018] 4. The first and second main pipes of this utility model are also provided with air inlet pipes, and air inlet pipe valves are installed on the air inlet pipes, which can be opened intermittently during the maintenance of the main pipes to ensure the cleaning efficiency of dust.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] Please see Figures 1-3 This utility model provides the following technical solution: a poly process silane waste gas treatment device, including a tailpipe connecting pipe 1, a first main pipe 2, and a second main pipe 4. The tailpipe connecting pipe 1 is connected to the first main pipe 2 and the second main pipe 4 respectively through a three-way valve 5. The first main pipe 2 and the second main pipe 4 are arranged side by side. The first main pipe 2 is provided with 9 gas outlet pipes 21, and gas outlet pipe valves 22 are installed on the gas outlet pipes 21. The structure of the second main pipe 4 is the same as that of the first main pipe 2. Waste gas treatment components 3 are connected to the corresponding gas outlet pipes 21 on the first main pipe 2 and the second main pipe 4. The waste gas treatment components 3 include a fan 10, and the exhaust power of the fan 10 is 35kw-40kw (depending on the actual required negative pressure).

[0026] By adopting the above technical solution, this utility model sets up a first main pipe 2 and a second main pipe 4. When the first main pipe 2 needs maintenance, exhaust gas is discharged through the second main pipe 4; conversely, exhaust gas is discharged through the first main pipe 2. This avoids affecting exhaust gas discharge during main pipe maintenance and ensures the continuity of TOPCon battery production. This utility model uses a fan 10 to generate negative pressure to extract dust from the main pipe that needs maintenance, eliminating the need for tedious dragging and cleaning with tools, reducing manual operation, and improving maintenance efficiency.

[0027] Specifically, the exhaust gas treatment component 3 includes a combustion device 7 and a dust removal device 9. The combustion device 7 is connected to the outlet pipes 21 on the first main pipe 2 and the second main pipe 4 via branch pipes 6. The combustion device 7 is connected to the dust removal device 9 via connecting pipes 8. A fan 10 is installed on the dust removal device 9, which is a pulse-jet bag filter dust collector and includes an airlock-type ash discharge device for automatic ash discharge. The combustion device 7 is made of SS304 material and is a silane combustion canister with a dust collection bin.

[0028] By adopting the above technical solution, the exhaust gas is treated by the combustion device 7 and the dust removal device 9, which not only meets the daily exhaust gas treatment needs, but also treats the residual exhaust gas and the dust cleaned up during maintenance, reducing or avoiding dust overflow during maintenance.

[0029] Specifically, the combustion device 7 is connected to a protective gas inlet pipe and an auxiliary gas inlet pipe.

[0030] By adopting the above technical solution, inert gas and combustion-supporting gas are introduced into the combustion device 7 to ensure the treatment effect of waste gas. The inert gas and combustion-supporting gas include, but are not limited to, nitrogen or compressed air.

[0031] Example 2

[0032] The difference between this embodiment and embodiment 1 is that, specifically, a connecting pipe valve 81 is installed on the connecting pipe 8.

[0033] By adopting the above technical solution, the connecting pipe valve 81 is a normally open valve, which is used to cut off the connection between the combustion device 7 and the dust removal device 9 when abnormal conditions occur or when the combustion device 7 is being cleaned and maintained.

[0034] Example 3

[0035] The difference between this embodiment and embodiment 1 is that, specifically, the first main pipe 2 and the second main pipe 4 are also provided with four air inlet pipes 23, and air inlet pipe valves 24 are installed on the air inlet pipes 23.

[0036] By adopting the above technical solution, one of the air inlet pipes 23 is used for connection to the three-way valve 5, and the other air inlet pipe 23 can be opened intermittently during the maintenance of the main pipe to ensure the cleaning efficiency of dust.

[0037] Specifically, both the outlet valve 22 and the inlet valve 24 are flanged butterfly valves or gate valves, and in this embodiment, butterfly valves are preferred.

[0038] By adopting the above technical solutions, good sealing and rapid switching action are guaranteed.

[0039] The maintenance steps for the main pipe according to this utility model are as follows (taking the first main pipe 2 as an example):

[0040] S1. Open all the outlet valves 22 of the second main pipe 4, and switch the exhaust gas into the second main pipe 4 through the three-way valve 5;

[0041] S2. Close all outlet valves 22 of the first main pipe 2;

[0042] S3. Open one or two vent valves 22 in the middle of the first main pipe 2, and close the corresponding vent valves 22 on the second main pipe 4.

[0043] S4. The dust in the first main pipe 2 enters the combustion device 7 under the exhaust of the fan 10, and then enters the dust removal device 9 through the connecting pipe 8. The dust and exhaust gas are separated in the bag filter and pulse jet system. The lower end of the dust removal device 9 is connected to a dust collection bag.

[0044] S5. During maintenance, the air inlet valve 24 of the first main pipe 2 is opened intermittently for 1 minute at a time, with an interval of 5 minutes.

[0045] S5. After maintenance is completed, close the vent valve 22 on the first main pipe 2 and open the vent valve 22 on the second main pipe 4.

[0046] In summary, this invention features a first main pipe 2 and a second main pipe 4. When the first main pipe 2 requires maintenance, exhaust gas is discharged through the second main pipe 4; conversely, exhaust gas is discharged through the first main pipe 2, thus preventing maintenance of the main pipe from affecting exhaust gas discharge and ensuring the continuity of TOPCon battery production. This invention uses a fan 10 to generate negative pressure to extract dust from the main pipe requiring maintenance, eliminating the need for tedious dragging and cleaning with tools, reducing manual operation, and improving maintenance efficiency. This invention treats the exhaust gas using a combustion device 7 and a dust removal device 9, satisfying daily exhaust gas treatment needs and handling residual exhaust gas and cleaned dust during maintenance, reducing or preventing dust spillage during maintenance. The first main pipe 2 and the second main pipe 4 are also equipped with an air inlet pipe 23, on which an air inlet valve 24 is installed. This valve can be opened intermittently during main pipe maintenance to ensure efficient dust removal.

[0047] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
