Patent ID: 8608911

Claim:
A device for desalination of water, comprising: an inlet for saltwater; a first inner container with a first inner container wall arranged rotatably around an axis of rotation with holes in the first inner container wall forming a distributor for spraying saltwater on an evaporation surface; a condensation surface for condensation of evaporated water; a second container with a second container wall arranged rotatably around the axis of rotation, the inside of which constitutes an evaporation surface; a heater for heating of the second container and thereby also the evaporation surface a motor which is arranged to rotate the inner container and outer container around the axis of rotation, wherein the second container surrounds the first inner container and is connected fixed to the first inner container, wherein distributor for spraying salt water on the evaporation surface is constituted by first holes which are arranged in the container wall of the first inner container so that water may pass out to the second container, wherein second holes are arranged in the container wall of the second container so that steam may pass out from the second container, and wherein the condensation surface is arranged for condensation of steam which passes out through the second holes in the container wall of the second container; and an outlet for condensed water attached to the condensation surface.
