Abstract
PURPOSE: To prevent leakage of a solvent to the atmosphere by a method wherein the solvent is desorbed by hot air and a desorbing cooling apparatus is constituted in a hermetially sealed recirculation system to recover the solvent unstable to water in good efficiency only by simple post-treatment without losing safety of said solvent.
CONSTITUTION: In an adsorbing process, valves 11', 19' are closed and valves 1', 4' are opened and a solvent containing exhaust gas from a dry cleaner or the like is introduced from a gas introducing pipe 1 to be adsorbed to an adsorbing member 5 comprising activated carbon fiber and exhausted from an exhaust pipe 4. in a desorbing process, the valves 1', 4' are closed and valves 11' 18', 19' are opened and hot air is passed through the adsorbing member from a steam type air heater 16 through an arranged pipe 19 to desorb the solvent. The hot air containing the solvent is sent to a heat storing type cooler 13 from an arranged pipe 11 and the solvent and moisture in said air is condensed and liquefied to be taken out from a separator 20 and the cooled air is heated again in the air heater 16 to be recirculated as hot air. After this treatment, a valve 18 is closed and cooling air from the cooler 13 is recirculated and the residual polvent in an adsorbing chamber 3 and a recirculation circuit is re-adsorbed to the adsorbing member 6 and the next adsorbing process is prepared.
