Distilled water preparation device

Abstract

The invention provides a distilled water preparation device. The distilled water preparation device utilizes waste heat of a refrigeration system to realize preparation of distilled water. The distilled water preparation device comprises a tap water storage container, an evaporation unit, a condensation unit, a first distilled water storage container, a second distilled water storage container, a waste water container and a vacuum device. A water condensation assembly in the refrigeration system is located in the evaporation unit and is used for heating tap water in the evaporation unit, and an evaporation assembly is located in the condensation unit and is used for condensation of vapor produced by the evaporation unit so that the distilled water preparation device can fully utilize waste heat of the refrigeration system to heat tap water. In the refrigeration system, a refrigeration working medium cycling continually can replace tap water as a condensation medium so that energy saving and water saving effects of the existing distilled water preparation device are further improved.

Description

Technical field [0001] The invention belongs to the field of water preparation, and specifically relates to a distilled water preparation device. Background technique [0002] The distilled water preparation device is one of the necessary equipment in the biochemical laboratory. The commonly used distilled water preparation equipment generally uses electric heating to boil the tap water, and then uses the tap water to condense the steam to obtain distilled water. This method, on the one hand, requires a large amount of heat energy to heat the cold water and provide the vaporization heat necessary for the conversion of liquid water into steam. On the other hand, it also needs to provide a large amount of cold water to reduce the steam temperature and condense the water vapor into liquid distilled water. Obviously, this method consumes electricity and water resources. [0003] Some designs reduce the boiling point of water by reducing the pressure in the system to achieve the purpos...

Problems solved by technology

This method, on the one hand, requires a large amount of heat energy for heating cold water to provide the heat of vaporization necessary for the conversion of liquid water into steam; , obviously, such a method consumes both electricity and water resources

[0003] Some designs reduce the boiling point of water by reducing the pressure in the system, so as to achieve the purpose of energy saving, such as patent CN 201864591 U, but the cooling process still consumes a lot of water, which cannot achieve the effect of water saving
