Abstract

PURPOSE:To efficiently desalinate sea water over a long period of time, by providing an evaporation chamber equipped with a transparent cover body above a float body, opening the interior of the evaporation chamber to sea water, and floating a heat- absorbing body having permeability to sea water in the inner chamber of the evaporation chamber. CONSTITUTION:Sea water introduced through a connecting pipe 13 into the inner chamber 11 of a floating body 10 and having permeated a water-permeable heat- absorbing body 14 such as sponge is heated by the heat-absorbing body 14 heated by solar light streaming in an evaporation chamber 20 through a transparent cover body 21 and continuously evaporated. Steam formed by the evaporation and permeating the evaporation chamber 20 is condensed and liquefied inside the float body 10 and concurrently on the inner surface of the cover body 21 by the difference between the temps. of the outside air and the interior of the evaporation chamber 20. The resulting liquid is let flow downwards along the inner surface of the cover body 21 and the outer surface of an intermediate cover body 22 to the bottom of an outer chamber 12 and accumulated therein. When the fresh water accumulated on the bottom of the outer chamber 12 reaches a predetermined head of water, it is supplied to a reservoir 50 by the automatic operation of a valve 40.

It is heated and continuously evaporated by the heat absorbing body heated by the sunlight shining through it. The water vapor that evaporates and fills the evaporation chamber 20 condenses and liquefies inside the floating body 10, which is floating in the sea and is constantly cooled by seawater. It condenses and liquefies on the inner surface, flows down the inner surface of the lid 21 and the outer surface of the intermediate lid 22 to the bottom of the outer chamber 12, and accumulates there.

Since the check valve 32 is provided to allow air to be sucked into the seawater inlet/outlet chamber 30, the wave motion and the floating body 1 due to the wave motion are
Due to the oscillation of 0, the pressure inside the floating body 10 can be automatically reduced using the waves flowing in and out of the seawater inlet/outlet chamber 60, and the above-mentioned evaporation effect can be significantly promoted.
