Plant for sea water desalinizing using solar energy

Apparatus for desalination of sea water by the utilization of solar energy for distillation of said sea water, comprising a heat caption unit that automatically follows the movement of the sun serving as a heat source, a sea water collecting tank, a pre-heating tank having a discharge duct, a plurality of evaporators which serve to evaporate steam out of sea water, said plurality of evaporators being connected in series, and distilled water storage tanks;

• said preheating tank which pre-heats the sea water and cools the steam and said sea water collecting tank being situated beside each other at different levels, the adjoining walls of the two tanks having an opening for a through-flow tube;
• the discharge duct of the preheating tank connecting into the plurality of evaporators, the first of the plurality of evaporators having a heating agent inlet and a heater heated by the heating agent, the second and the subsequent evaporators having a heating system consisting of pipe rings utilizing hot vapor and pipes connecting the pipe rings, at least one parabolic collector made up of module elements serving as heat collecting units for heating the heating agent that heats the first evaporator, said heat collecting units having a funnel-shape means with a bottom hollow, a high heat-resistant metal or ceramic coating covering the wall of said means, a heat receiver means having an inlet pipe and a discharge pipe, baffle plates or pipe bundles inside said receiver for heating the heating agent, wherein the inlet pipe of the receiver is connected to a discharge pipe of the first evaporator discharging a cooled heating agent, while the discharge pipe of the receiver is connected to the heating agent inlet of the first evaporator.
