Portable water purification system

摘要

A water purification device mounted within a housing adapted to be positioned on an existing water cooler/dispenser has a valve control member extending from the base of the housing and is positionable within the water reservoir of the dispenser to control the release of purified water from the device to the reservoir. The device includes a feedwater tank into which supply water is fed and which feeds water to a water level control tank which communicates with the bottom of a boiler which is maintained at the same level as the water in the control tank. The control tank includes a control valve which maintains the water in it to a predetermined level above the level of the heating element in the boiler. The boiler is connected to condenser coils for condensing vaporized water from the boiler to form distilled water which is directed through a carbon filter to a distillate storage tank where the purified water is stored until required by the water cooler/dispenser. Baffles above the boiler heating element preclude heated water from being driven into the condenser.
