Abstract
Abstract A flash distilling apparatus utilizing high and low pressures and temperature differences characterized in that by positively imparting agitations to a stock solution flowing in a flash chamber portions of the stock solution existing in regions lying deep and having higher pressures than the saturated vapor pressure owing to their static pressures are forced to move to the vapor-liquid interface, thereby making it possible to utilize differences in the sensible heat of the solution due to pressure differences between flash chamber compartments for effective evaporation.
