Title:
PURE LIQUID PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/135724
Kind Code:
A1
Abstract:
Provided is a pure liquid production device capable of producing pure liquid such as pure water efficiently by a simple structure, thereby reducing the cost related to the supply of the pure water and the like. Together with a series of units, from a heater (11) to a condenser (14), for obtaining pure liquid from evaporated vapor, a drain tank (18) for storing liquid not evaporated by an evaporator (12) and liquid collected by a separator (13) is disposed, after the liquid discharged from the evaporator (12) and the separator (13) and new liquid are mixed in advance in the drain tank (18), the mixed liquid is pressurized by a pump (19) and supplied to the heater (11). Consequently, the drain tank (18) serves as a pressure buffering part, and the maintenance of the pressures in the respective units such as the evaporator (12) and the separator (13) is facilitated, thereby making it possible to reduce the load on a reduced pressure exhaust device (70) for producing a reduced pressure state in order to evaporate liquid, and dispose the required minimum valves and the like for maintaining the pressure, thereby achieving the simplification of the device structure and cost reduction.
