Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment devices, and more specifically, to a waste gas recovery device of a silicon-carbon negative electrode material production line based on a CVD method. Background Art

[0002] Chemical vapor deposition refers to the process of introducing gaseous reactants or liquid reactants containing thin film elements and other gases required for the reaction into the reaction chamber, and chemical reactions occur on the substrate surface to form thin films. In ultra-large-scale integrated circuits, many thin films are prepared by CVD. Silicon-carbon composite negative electrode material is a new type of lithium-ion battery negative electrode material developed in recent years. It consists of silicon-based active materials and carbon-based conductive materials. Silicon-based active materials can provide high capacity and good energy density, while carbon-based conductive materials can provide good conductivity and thermal stability. Therefore, silicon-carbon composite negative electrode materials have good comprehensive properties and can effectively improve the energy density and cycle life of batteries.

[0003] After searching, the waste gas recovery system with the existing patent number CN215506223U includes a first connecting plate, a mounting hole is provided inside the first connecting plate, and a second threaded hole is provided inside the first connecting plate, the second connecting plate and the third connecting plate at the lower end of the first threaded hole. The cover for collecting smoke in the waste gas recovery system is set to a structure that can be spliced, and is assembled by splicing the first connecting plate, the second connecting plate, the third connecting plate and the top plate. At the same time, the connecting plates are reinforced by fixing blocks and bolts, which is convenient for installation and disassembly, transportation and use. An exhaust pipe is added to the outside of the waste gas recovery system. Through the function of the ventilation mechanism, the pungent odor generated by the printing press during printing is collected, and the gas is filtered through the activated carbon filter layer inside the filter box and then discharged to the outside, which reduces pollution to the environment and greatly improves practicality.

[0004] When using a waste gas recovery box to filter and treat the waste gas in the production process of silicon-carbon negative electrode materials, waste debris is easily accumulated on the surface of the filter plate, affecting the filtration performance and reducing the use effect. Therefore, we proposed a waste gas recovery device for the silicon-carbon negative electrode material production line based on the CVD method to solve the above-mentioned problems.
