Method of cleaning workpieces with a liquid solvent

摘要

A method and system for cleaning workpieces with a liquid solvent in a treatment chamber which is connected into a drying gas circuit for the purpose of drying the workpieces. The drying gas circuit includes in series one after the other a ventilator, a condenser, a heating device and an adsorber containing activated carbon. The circuit is operated such that during a drying phase the condenser is cooled, the heating device switched on and the activated carbon regenerated by the hot circulating air whereupon, during an adsorption phase with the condenser switched on and the heating device switched off, the remaining solvent vapor is withdrawn from the circulating drying air by the activated carbon.
