<p>PURPOSE:To perform the desalting of seawater by the temp. difference between a high productivity sea area and a solar energy high temp. basin or high temp. surface water, by creating the high productivity sea area by pumping low temp. submerged water. CONSTITUTION:The high temp. seawater supplied from a solar energy water pumping-up basin is evaporated in an evaporator 18. Low temp. submerged water 13 rich in nutritive substances is pumped up to a condenser 15 by a cold water pump 14 through a cold water pipe and the steam from a fluid recirculation passage 16 is cooled and condensed by the condenser 15 to obtain fresh water. An uranium and lithium recovery adsorbing tower 21 pref. uses an adsorbent having good absorbing quantity, selectivity and desorptivity and is pref. arranged to a confluent pipe of cold water and hot water. By this constitution, the total system can be established and economical efficiency is enhanced.</p> |
