Abstract
Abstract Disclosed is a distillatory apparatus in which distilling chambers are disposed in array and the atmospheric pressures in the distilling chambers are selected to gradually lower in the order of them and maintained at such gradually decreased values. The distilling chambers are each supplied with an original liquid. The original liquid supplied to each distilling chamber flows on a partition wall between the distilling chamber and the adjacent one of higher atmospheric pressure. While flowing on the partition wall, the original liquid is heated to be evaporated and vapor makes contact with a partition wall on the side of the adjacent distilling chamber of lower atmospheric pressure and is cooled thereby to be condensed to a distilled liquid. The atmospheric pressures of the distilling chambers are selected so that, by the heat released by the condensation of the vapor in each distilling chamber, the partition wall is heated and that the original liquid in the adjacent distilling chamber of lower atmospheric pressure is evaporated by the heat of the partition wall. The original liquid supplied to each distilling chamber is heat exchanged with the distilled liquid and the remaining original liquid, that is, a concentrated liquid, drained out from the distilling chamber.
