Document Type and Number:
Japanese Patent JPH06154502
Kind Code:
A
Abstract:
PURPOSE: To provide equipment for recovering a solvent which is capable of simultaneously performing decompression of a decompression chamber and feeding a liquified solvent into a recovery tank only by a single pump without using a vacuum pump.
CONSTITUTION: A recovered solvent in a recovery tank 21 is forcedly circulated through a circulation pipeline 31 by a pump 32. A fresh solvent is vaporized in a decompression chamber 4, cooled and liquefied by cooling means 38, 9. When the recovered solvent is passed through an ejector 33 on the way, the fresh solvent is drawn from a recovery pipeline 39 side and joined to the recovered solvent and fed into the recovery tank 21. At the same time, the decompression chamber 4 is decompressed.
