<p>PURPOSE:To surely treat a gaseous solvent by providing an opening and closing door and a gate door to a chamber for housing a material to be cleaned and connecting a gaseous solvent treating mechanism to the chamber. CONSTITUTION:The material 3 to be cleaned is placed in the housing chamber 22 of a solvent recovery device 19 connected to the cleaning device 1. At this time, the opening and closing door 20 is opened, the material 3 is placed in the housing chamber 22, and the opening and closing door 20 is closed up tight to isolate the cleaning device 1 from the housing chamber 22, and the treating mechanism 26 for removing the cleaning soln. 14 deposited on the material 3 is operated. Consequently, the gas in the housing chamber 22 is repeatedly and continuously treated by the treating mechanism 26, and the cleaning is continued until the org. solvent, etc., deposited on the material 3 are surely removed. The gaseous solvent is recovered in this way at a low cost.</p> |
