Title:
APPARATUS FOR PREPARING DISTILLATED WATER
Document Type and Number:
WIPO Patent Application WO/2017/101782
Kind Code:
A1
Abstract:
An apparatus for preparing distillated water comprises a liquid-obtaining tank (10) for storing raw material water and a distillated water tank (20) for collecting distillated water. The liquid-obtaining tank (10) communicates with the distillated water tank (20) through a pipe (11), and a drawing and draining apparatus (30) used for drawing air in the liquid-obtaining tank (10) to the distillated water tank (20) is provided on the pipe (11). The liquid-obtaining tank (10) and the distillated water tank (20) are further provided with air extracting valves (12) communicating with the evacuation apparatus (13). The evacuation apparatus (13) evacuates the liquid-obtaining tank (10) and the distillated water tank (20), so that the two tanks remain in a same negative pressure state. By means of the apparatus, a boiling point of water is decreased through evacuation, so that the water boils at normal temperature, to reach a saturated vapor pressure state, and then water vapor is continuously drawn away. A low pressure distillation manner is used instead of an existing manner of preparing distillated water through electric heating, greatly improving an energy utilization rate, and reducing the energy consumption.
