Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a flue gas purification process in the negative electrode material coating section, which solves the problem that the existing purification method is relatively complicated and has poor purification effect, and it costs money to process the flue gas each time. A large number of working hours of production personnel greatly reduce the purification efficiency of flue gas. It is impossible to realize the fast and efficient flue gas purification method for treatment, and it is impossible to achieve the simultaneous liquefaction and dust removal of flue gas to complete organic gas and dust removal. The purpose of simplification of the purification process cannot be achieved to reduce the cost of flue gas purification
