Abstract
Provided is a pure liquid manufacturing apparatus capable of manufacturing pure liquid such as pure water efficiently. Together with a series of units, from a heating unit to a condensation unit, for obtaining pure liquid from vapor, a drain tank unit for storing liquid is disposed, after the liquid discharged from the vaporization unit and the separation unit and new liquid are mixed in advance in the drain tank unit, the mixed liquid is pressurized by a pump unit and supplied to the heating unit. Consequently, the drain tank unit serves as a buffer for pressure, thus making it possible to maintain easily the pressure in the respective units such as the vaporization unit, etc., and reduce load of a vacuum exhaust unit to ensure a reduced pressure state, and dispose the required minimum valves for maintaining the pressure, thereby achieving the simplification of the apparatus structure.
