SOLAR WATER DISTILLATION STATION Russian patent published in 2022 - IPC C02F1/14 

FIELD: cleaning.

SUBSTANCE: invention relates to purification of sea water and ground water by distillation to provide drinking water for agriculture, municipal services and can be used to obtain distilled water for process use. Solar water distillation station comprises a vacuum column, a vacuum pump, a water pump for supplying water to the vacuum column from a source water tank, a heat exchanger connected to the distilled water tank, pressure equalization hole, electric valve regulating water supply to column, controller of lower mark of water in column, pressure control valve. Proposed station comprises bottom valve to discharge water from vacuum column, water pump suction line valve and valve to return non-condensed water vapour from distilled water tank to vacuum pump suction line via pressure control valve. In the upper part of the vacuum column there is a spherical glass container with double-layer glass connected to the inlet of the vacuum pump. Station comprises mirrors reflecting and concentrating solar radiation on spherical glass container of vacuum column, with possibility of heat transfer required for water evaporation.

EFFECT: increasing the productivity of a desalination plant by boiling and condensing water at low pressure and temperature using reflective concentric mirrors and a vacuum pump.
