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