Abstract

A system for distilling sea or brackish water includes a feed water arrangement for supplying feed water from a feed water source to one or more flashing stages. Each flashing stage has a water flash evaporator for vaporizing at least part of the water therein, and a condenser for receiving the vapour and converting at least a part of the vapour into distilled water. A heat storage arrangement provided with a heat generating source for storing heat energy is used to heat a fluid medium flowing through it. A heat exchange arrangement receives the hot fluid medium and transfers heat to a stream of vapour flowing under pressure from each flashing stage. The vapour leaving the heat exchange arrangement being at a raised temperature is arranged to be condensed into water at the condenser and to transfer some of its latent heat to the evaporator.

Dependent claims

A water distillation system comprising a feed water arrangement arranged to supply feed water from a feed water source to one or more flashing stages, the or each said flashing stage having a water flash evaporator arranged to vaporise at least a part of the feed water therein, and a condenser arranged to receive the vapour formed from the feed water in the evaporator and to convert at least a part of the vapour into water;

a heat storage arrangement having a heat generating source arranged to store heat energy for heating a fluid medium flowing therethrough;
a heat exchange arrangement arranged for the hot fluid medium and a stream of vapour from the or each said flashing stage to flow therethrough so that heat from the hot fluid medium is at least partly transferred to the stream of vapour;
and the stream of vapour leaving the heat exchange arrangement being at a raised temperature is arranged to flow to said condenser to be at least partly converted by condensation into water and to transfer at least some of its latent heat to the evaporator.
