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.
Claims9
Distillation apparatus comprising one or more heat transfer tube, each of the said one or more tubes aligned about a vertical axis, means to drive said heat transfer tubes about a wobbling center on said vertical axis without rotating the transfer tubes, means to direct a stream of fluid toward the inner surface of each of said tubes, the wobble motion imparted to each of said tubes serving to cause said fluid stream to cling to the inner surface of the tube away from the wobbling center whereby the resultant revolving flow stream serves to wipe the inside surface of the tube to form a thin film with low heat resistance and thus to facilitate evaporation and carry the residue and reflux downward with low resistance.
