I、Introduction to system principle
The NMP solvent evaporates after heating in the coating process. The NMP recovery equipment condenses the volatile gas step by step, gradually reduces the concentration of NMP in the gas through multistage condensation, and finally discharges the purified gas.
II、System composition
The recovery system consists of solvent NMP recovery host, intelligent control system, air duct system, waterway system, solvent NMP collection system and tail gas treatment system.
Equipment Introduction
1 .Purpose of equipment
QR series equipment is mainly used in lithium battery industry; It is a high-performance environmental protection equipment for the treatment of NMP waste gas generated in the coating process of lithium battery manufacturing.
2 .Equipment characteristics
The NMP waste gas is treated and purified by water cooling and spraying, which has high-efficiency recovery function and high-efficiency purification effect.
The equipment is easy to operate with clear instructions.
Combined design, the main components can be easily disassembled and maintained.
High efficiency recovery of NMP, with high economic benefits for users
