JRH Series Refrigerated NMP Recovery System

  • JRH Series Refrigerated NMP Recovery System
  • JRH Series Refrigerated NMP Recovery System

Process Flow Chart:


This equipment condenses and recovers NMP solvent by freezing the exhausted air out of coating process of lithium batteries. By using cooling recovery devices (heat exchanger, cooling water cooler, chilled water cooler), part of NMP will condense from the air, and the concentration of NMP in exhausted air reduced below 300ppm after condensation. ZJRH rotary NMP recovery system able to do the further NMP recovery processing and meet the environmental emission standards.

● Control mode: PLC, DDC control and coordinated control system; Highly  automatic control, each recovery device is designed with automatic control system and interlocking system, which ensure the safe production and stable operation of the coating machine and the recovery device.

● High-efficiency centrifugal fan, heat-resistant double-layer panel, stainless steel frame, electrical multiple protection for safe operation.

● With obvious energy saving effect, as the system is closed and circulated, processed air will be sent back to the coater oven through heat exchanger, which greatly reduced energy consumption.

● NMP solvent recovery rate ≥ 97%, solvent recovery concentration ≥ 85%, exhaust NMP concentration ≤ 1ppm.
