ABSTRACT:
An apparatus for removing non-volatile residues and impurities from a used solvent includes a self-scrubbing heating distillation subassembly for separating purified solvent for reuse and a controlled waste collector subassembly for overflowing concentrated residues and impurities stripped from the used solvent into an easy-to-service container. The apparatus may be disposed in a parallel in-line relationship with a circulating solvent flow circuit, such as in a dry cleaning operation, to continuously withdraw and purify aliquot portions of the circulating solvent stream, returning good solvent back to the flow circuit and concentrating non-volatile residues and impurities to a removable, environmentally sound serviceable container. The new and improved self-scrubbing heater assembly causes a rapid turbulent reboiling flow of solvent within a confined column and substantially avoids build up of residues on heat exchange surfaces for prolonged heater life and longer uninterrupted service life before service is needed.
