Abstract
A solvent recovering system capable of recovering the solvent wetting solvent-cleaned articles, such as machine parts, electronic parts or medical instruments, without releasing the solvent into the atmosphere. A solvent vapor processing unit is connected by circulation passages to a closed chamber for accommodating solvent-cleaned articles. The vapor of the solvent evaporated from the solvent-cleaned articles is circulated through the closed chamber and the solvent vapor processing unit to subject the vapor repeatedly to adsorption or condensation to recover the solvent perfectly so that the solvent may not be released into the atmosphere to prevent air pollution and harm on health.
