REQUIREMENTS FOR THE RECOVERY OF SAFE SOUTH WATER BY DISTILLATION OF CONTAMINED PRIMARY WATER

摘要

The invention relates to a device for obtaining clean fresh water by distilling contaminated primary water, especially saltwater. The device comprises a reaction chamber with a solar heatable evaporator surface that can be wetted with primary water, a collecting device for non-evaporated primary water, a coolable condensation surface on which water steam of the primary water is condensed, and a collecting device for the fresh water evacuated from the condensation surface. The evaporator surface and the condensation surface are mounted coaxially in the reaction chamber and are separated by a heat insulating layer. An air circulation chamber and the water steam contained therein runs upward through an outer chamber formed between the evaporator surface and the wall of the reaction chamber and outward through an inner chamber formed by the coaxial condensation surface.
