Beschreibung
Zusammenfassung:	The utility model discloses a lithium ion battery coating process NMP (N-Methyl Pyrrolidone) recovery device, which belongs to the field of NMP recovery and comprises a coating oven, a coating oven exhaust fan, a gas-gas heat exchanger, a surface air cooler, a return fan, an exhaust fan, a separation membrane component, a return air induced draft fan, a coating oven circulating fan and an electric heater. The coating oven is connected with the coating oven exhaust fan and is used for producing high-temperature NMP-containing waste gas and conveying the NMP-containing waste gas to the coating oven exhaust fan; the coating oven exhaust fan is connected with the gas-gas heat exchanger and is used for conveying the received NMP waste gas to the gas-gas heat exchanger; and the gas-gas heat exchanger is connected with the surface air cooler and the air return induced draft fan and used for carrying out heat exchange cooling on the received NMP waste gas and then conveying the NMP waste gas subjected to heat exchang
