Method and apparatus for solvent recovery from waste wash liquid of printing machine |
摘要 |
A solvent recovery method and apparatus recover waste wash liquid generated in automatic washing of a printing machine so as to enable a printing machine washing of high productivity, excellent safety and health effect, and low cost. The solvent recovery apparatus has a gravity separation tank (1) for receiving waste wash liquid used for washing of the printing machine and separating it by a specific gravity difference. A vaporizer (2) receives, heats and vaporizes the separated liquid from the tank (1) in order from a lower layer liquid (H) to an upper layer liquid (L). A condenser (3) receives, cools and condenses, by water (W), the vapor from the vaporizer (2). A distillate gravity separation tank (4) receives liquid from the distillate gravity separation tank (4) receives liquid from the condenser (3) and holds it statically to separate the liquid into organic solvent (S) and water (W).
