Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment and recovery device for lithium battery production. Background Art

[0002] With the rapid development of lithium battery technology, lithium batteries are now widely used in mobile phones, computers, cars, electric vehicles, satellites, space shuttles and other fields due to their small size, light weight, high energy density and long service life, bringing convenience to our work and life. At the same time, lithium battery factories often use NMP as an organic solvent in the process of battery production, which will produce waste gas containing a large amount of NMP during the drying process, which will cause great harm to operators and the environment. Therefore, the waste gas produced by lithium batteries must be purified by waste gas treatment equipment before it can be safely discharged.

[0003] In the prior art, wheel adsorption and desorption are often used to recover NMP waste gas, and the zeolite adsorption method is mostly used. After the waste gas is collected, it is guided through a waste gas pipeline with a zeolite adsorption layer, and the NMP component in the waste gas is adsorbed by zeolite to complete the waste gas treatment.

[0004] However, in actual practical use, the adsorption capacity of the zeolite layer will decrease after long-term use. At the same time, it may be worn or otherwise damaged during use, which will affect the exhaust gas treatment effect and need to be replaced. However, the existing technology requires disassembling the exhaust gas pipe for replacement, which is very inconvenient. Summary of the invention
