Abstract

PURPOSE: To render the operation of a vacuum pump unnecessary during the vacuum distillation by a mechanism wherein a water vapor generated by the vacuum boiling of an aqueous solution and a cooling water are blended and poured into a vacuum space of a vacuum tower forming a vacuum space by a water colum head in a sprayed pattern to condense a water vapor.
CONSTITUTION: The liquid temperature within a distillation kettle 3 is selected within the range from a room temperature to 100°C and the water vapor generated in the distillation kettle 3 is introduced to a vacuum tower 6 through an arranged pipe 13 wound by a heat insulating material 4. The water vapor introduced to the head portion of the vacuum tower 6 is cooled by mixing the said water vapor with a water in a mist form injected from a spray nozzle 5 and condensed within a vacuum tower 6. The water amount from the spray nozzle 5 is about 10W100 times of the vapor weight to be condensed. Because the head portion of the vacuum tower 6 is evacuated (practically maintained at the pressure corresponding to the vapor pressure of water) by Torricelli's theory, the height of the vacuum tower 6 is preferably above 10m. Thereby, the operation of a vacuum pump is unnecessary during the vacuum distillation and a large amount of water is not necessitated.
