摘要：PROBLEM TO BE SOLVED: To provide a solvent recovering apparatus and method capable of efficiently distilling and recovering even a solvent containing a pollutant changed by heat such as thermosetting resins or the like, a highly viscous pollutant or the like without bringing about the lowering of efficiency or closure of a heat exchanger. SOLUTION: The solvent is put in a distiller 10 and supplied to the heat exchanger 16 arranged lower than the distiller 10 to be heated and the heated solvent is again introduced into the distiller 10 in a liquid phase state to generate the vapor of the solvent in the distiller 10. The vapor of the solvent generated in the distiller 10 is cooled by a condenser 12 to obtain the regenerated solvent in a liquid phase state from which the pollutant is removed.
