TECHNICAL FIELD
[0001] The utility model relates to waste discharge technical field especially relates to a novel acid discharge pipeline interface connection assembly. BACKGROUND
[0002] In TOPCON photovoltaic technology, boron diffusion process is the core link to improve cell efficiency, but the crystalline dust discharge problem generated in its process has become a thorny problem in the industry. In the boron diffusion process, due to high temperature and chemical reaction, a large amount of fine and high-hardness crystalline dust will be generated. These dusts are extracted by vacuum pumps and need to be discharged to the solid waste treatment system of the plant through the acid discharge pipeline. However, in actual operation, dust is prone to blockage at various interfaces of the pipeline, which not only affects the smooth operation of the production line, but also may cause the production line to be down, thereby increasing maintenance cost and reducing production efficiency. This problem has long plagued companies in the industry and has become one of the bottlenecks restricting the further development and application of TOPCON photovoltaic technology.
[0003] To address this challenge, the industry has tried various methods, but the problem of dust blocking the pipeline still occurs frequently. Especially in the case of complex pipeline layout and numerous joints, the accumulation and blockage of dust are more likely to occur. This not only requires enterprises to manage dust discharge more carefully during production, but also urgently needs to find a more effective dust treatment and discharge scheme to ensure the stable operation of the production line and the efficient implementation of the boron diffusion process. Therefore, how to solve the problem of crystalline dust discharge in the boron diffusion process and avoid pipeline blockage has become a key technical problem to be solved in the development of TOPCON photovoltaic technology.
[0004] One existing solution is to install branch pipes on the main pipe, and the discharged waste can enter the main pipe through the branch pipes, which can effectively alleviate the blockage problem. However, the size of the branch pipe and the size of the connection between the main pipe are different, and it is necessary to ensure that the branch pipe and the main pipe connection have good sealing effect. If leakage occurs, waste will leak from the branch pipe and the main pipe, which will not only pollute the environment but also affect the discharge process. UTILITY MODEL CONTENTS
