Seawater desalination plant operated entirely by natural energy, includes open tanks filled by waves and connected by lines to divided pressure vessel

摘要

Three open tanks (A, B, C) are connected by lines (R3, R4, RS) to a pressure vessel (E, EL). They lead from low in the water region of the tanks, into the partially water-filled pressure vessel. Tank A is held at constant water level by approaching waves. Tank B is held at a constant, but lower water level than tank A, by subsiding waves. The pressure vessel is divided into two, both sides being connected together by a valve (V10). Lines (R3, R4) are connected with pressure vessel section E. The insulated line (RS) is connected to the insulated pressure vessel section EL. In this section, a submerged absorption-cooling coil is provided, operated by solar energy. A further water tank (D) is connected low down to tank C, and has a manual valve (H4) for water removal. Line R3 is uninsulated and takes up solar heat. Ends of the lines (R3, R4, R5) always lie below the water level in the water tanks (A, B, C).
