A retired lithium battery electrolyte recovery system and recovery method

Abstract

The present invention belongs to the technical field of recycling retired lithium batteries, and relates to a retired lithium battery electrolyte recycling system and recycling method. The recycling system comprises: a crushing and volatilization subsystem, a dust collection and heat exchange subsystem, a condensation subsystem and several sets of absorption and blending subsystems; the crushing and volatilization subsystem is connected to the dust collection and heat exchange subsystem; the dust collection and heat exchange subsystem is connected to the condensation subsystem; the condensation subsystem is connected to several sets of absorption and blending subsystems; the technical solution of the present application is adopted to recycle and produce electrolyte products, which has good economic benefits; a heat exchanger is set to reasonably utilize heat and reduce energy consumption; circulating gas is reused to reduce inert gas consumption, improve the yield of F, P and organic solvents, and reduce the generation and emission of three wastes; the process, equipment and process control are simple and easy to industrialize.
