ABSTRACT:
Distillation apparatus in which a group of heat-transfer tubes are each driven to wobble about a vertical axis which passes through a wobbling center. A stream of fluid is directed to flow down inside each tube. The fluid stream tends to cling to the inner surface of the tube away from the wobbling center while it revolves with respect to the tube in response to the wobbling motion. The revolving flow stream wipes the inside surface of the tube to form a thin film which offers low heat resistance to facilitate the evaporation, carries away the residue by its lateral motion and carries the reflux downward with little restriction.
