Briefly describe the waste gas treatment technology and measures in the production of lithium-ion batteries

　　As electric vehicles bring revolutionary changes to the traditional automobile industry, the requirements for battery production and processing are also higher. During the production process of lithium batteries, especially during different time periods of formation, different gases will be generated. These gases have an impact on the generation operation. People and the environment are very harmful. N-methylpyrrolidone is used in the manufacturing process of the pole piece for the production of lithium-ion batteries. These N-methylpyrrolidone will be released into the atmosphere during the manufacture and coating of the pole piece.

It opens up a new way for organic waste gas treatment.　　High-temperature plasma incineration technology is a high-frequency (30KHz) high-voltage (100KV) high-power power supply under specific conditions to generate high-temperature plasma gas flow.　　The organic waste gas is compressed in the reactor and discharged into high-temperature plasma. The pressure of the reactor increases and the gas volume expands sharply. Under the dual effects of high temperature and high electric potential, the organic waste gas instantly becomes a high-temperature plasma (5 ten-thousandths of a second), in which long molecular chains are split into elemental atoms, and the organic matter removal rate is greater than 98%.　　 High-temperature plasma incineration device can directly treat low-concentration, high-volume organic waste gas without concentration. For every 10,000 cubic meters/hour of organic waste gas processed, only 10kW of electricity is consumed.　　In terms of capital investment and operating costs, the high-temperature plasma incineration scheme is superior to the concentrated adsorption + RTO incineration scheme.

　　Process flow diagram: 　　High temperature plasma incineration"Technical advantages: 　　Modular design, flexible configuration, economical and efficient, can treat organic waste gas with different concentrations and flow rates from hundreds of cubic meters to hundreds of thousands of cubic meters. 　　 No preheating is required, and it can be used immediately. 　　 Energy efficiency The exhaust gas discharge port temperature of high-temperature plasma equipment is only a few dozen degrees higher than the air intake temperature. It can handle high-concentration, complex, flammable, explosive, and moisture, solid, and oily industrial exhaust gas, and achieve compliance emissions　　 Low wind resistance, low energy consumption, no natural gas consumption, no carbon emission problem. There are no moving parts such as valves, and it can operate for tens of thousands of hours without failure. 　　 benzopyrene, dioxins and other difficult-to-handle substances that decompose instantly, Achieve up-to-standard emissions. (It is an ideal solution to the problem of dioxin emission from waste incineration exhaust gas) 　　 natural gas incineration method is required in flammable and explosive places or when the exhaust gas contains combustible components due to its working mechanism and structural defects. Consider the issue of explosion protection.　　High-temperature plasma incineration technology is an epoch-making technological change.　　Qinghai Taifeng Xianxing Lithium Energy Technology Co., Ltd. relies on the advantages of Qinghai Salt Lake resources and Peking University’s strong industrialization experience and foundation in lithium-ion batteries and their key materials. , In cooperation with Peking University, engaged in research and development, production and sales of cathode materials for new energy batteries. To build a large-scale research and industrialization base for new lithium-ion battery cathode materials with independent intellectual property rights in China. 　　 This time with Yongyan Environmental Protection The cooperation in the treatment project is the full trust of Yongyan Environmental Protection in the field of environmental protection, and it has also made great contributions to the company's waste gas pollution, technological progress, efficiency improvement, and maintenance of the health of the people.
