有機溶剤回収システム
Document Type and Number:
Japanese Patent JP7434891
Kind Code:
B2
Abstract:
To provide an organic solvent recovery system capable of recovering an organic solvent from an exhaust gas in a higher efficient manner.SOLUTION: An organic solvent recovery system of the invention includes: a cooling condensation device; a first air flow path for enabling a cooling process gas to flow; a first concentrator which discharges a first process gas, in which concentration of an organic solvent contained in the cooling process gas introduced from the first air flow path is further reduced, and which introduces a high temperature gas and desorbs the organic solvent to discharge a first desorption gas; a second air flow path for enabling a part of the first process gas to flow; a second concentrator which discharges a second process gas in which concentration of the organic solvent contained in the first process gas introduced from the second air flow path is further reduced and which introduces a high temperature gas and desorbs the organic solvent to discharge a second desorption gas; and a third air flow path which returns the first desorption gas and the second desorption gas to the cooling condensation device.SELECTED DRAWING: Figure 1
