Louis@lithmachine.com1500 m³/h Cylindrical Battery Line NMP Recovery System
This series of NMP recovery systems leverages the miscibility of NMP and water to treat and recover exhaust gases emitted from coating machines. The system is fully automated to maintain stable NMP concentration and TVOC levels in the exhaust air. Designed as an integrated system, it ensures operational stability and safety, while meeting national and local environmental protection standards. The system includes: spray tower, pump group, blower, ventilation ducts, and electrical control system. With a high recovery rate, low operating costs, compact and aesthetic structure, and excellent performance, it is easy to operate and ideal for coating processes in lithium battery laboratory production lines.

2. Working Principle:
The system recovers NMP from exhaust gases through soft water absorption. Waste gas enters from the bottom of the tower and passes through the adsorption unit, where NMP dissolves into water and steam. The treated gas then passes through a gas-liquid separator and a top spray rinsing unit to ensure complete NMP absorption. Due to the high temperature of incoming gas, energy exchange causes partial water evaporation. The system uses a circulation pump to recycle tower liquid through the adsorption unit, optimizing heat exchange and minimizing water waste while improving the NMP concentration in the recovered liquid. Treated exhaust gas can be discharged directly without further treatment, effectively achieving near-zero emissions.
