<p><P>PROBLEM TO BE SOLVED: To improve the technology to judge highly accurately the degree of an advance of regeneration (removal of adsorbed solvent), in the conventional technology for regeneration by passing steam through the active carbon when active carbon 9 provided in a washing machine apparatus adsorbs solvent vapor and the adsorption capability is degraded. <P>SOLUTION: A valve means (e.g., four-way valve 13) is placed in and connected with a space between a channel (arrows q and q' shown breadthwise by a dotted line) for supplying the solvent vapor in a washing tank 1 to the active carbon 9 from the first and a channel (shown vertically by a solid line) for supplying the solvent delivered from a solvent pump 3 to the washing tank 1 from the first. The steam 10 flowing through the active carbon 9 is introduced to a steel condenser 6 to be cooled and condensed via the valve 13 and the water content is separated by a water-content separator 7. The amount of separated water is measured by a water-level gage 14 and considered to be the amount of the steam 10 blown, thereby allowing the degree of the advance of regeneration of the active carbon 9 (removal of adsorbed solvent) to be highly accurately judged. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
