Description

Technical Field

[0001] The utility model relates to the technical field of recovery devices, in particular to a solvent recovery device with automatic purge. Background Art

[0002] The existing solvent recovery system includes a reactor, in which electric heating of heat transfer oil is used.

The existing solvent recovery system only evaporates the solvent in one container of the reactor, and the evaporation efficiency is low. Therefore, the present application aims to provide a solvent recovery device with high solvent recovery efficiency. Utility Model Content
