NOVELTY - Seawater is desalinated by flowing large-scale seawater through a pipe when extracting the seawater using uranium extractor, and separating the sea nuclear energy deuterium in the evaporated seawater at a temperature section with a boiling point higher than that of the water and lower than that of the deuterium with a deuterium water separator. The obtained sea nuclear energy uranium or deuterium is used for generating the electricity to provide the power for desalinating the seawater in large scale and supplying the water to the high elevation inland.    USE - Method for desalinating seawater with sea nuclear energy (claimed).    ADVANTAGE - The method solves shortage of water resource. The seawater desalinating device utilizes a high-efficiency heat exchanger, especially a five-pole evaporation system so that the large-scale seawater is evaporated and desalinated at high speed to meet the demand of the inland on the fresh water.    DETAILED DESCRIPTION - Desalinating seawater involves extracting seawater by heating, and supplying to the inland. The method uses a seawater supply system, a sea nuclear energy raw material acquiring system, an energy supply system, a heat exchange system, an evaporation and desalination system, and a fresh water remotely-conveying distribution system. The sea nuclear energy is obtained from the seawater supply system and the evaporation and desalination system, and is converted into the electric energy or the thermal energy to supply to the heat exchange system, evaporation and desalination system, and fresh water remotely-conveying distribution system. The technology device comprises a seawater pump (113), a seawater impurity filter (111), a seawater pipe (112), an uranium extractor, a seawater high-efficiency heat exchanger (201), a seawater high-efficiency and high-temperature heater (202), a seawater five-pole high-efficiency evaporation concentration drying chamber (301), a secondary fresh water high-efficiency condenser (203), a tail seawater stem washer (206), a secondary fresh water high-efficiency and high-temperature heater (204), a secondary fresh water secondary fresh water chamber (302), a deuterium water separator (502), a rectifying tower (503), a fresh water high-efficiency condenser (205), a tail fresh water stem washer, a water tank, a fluid heating distributor (208), a concentrated salt liquid cooler, a salt particle cooler (215), a large-power high-lift water pump, a high-level reservoir, and a fresh remote water conveying pipe (401).
