  • Publication number: 20240002257
    Abstract: Proposed is a complex system of offshore wind power generation, seawater desalination, and water electrolysis. The system may include a wind power generator which generates electric power in such a manner that blades are rotated by wind power. The wind power generator may include a cooler for preventing a overheating phenomenon caused by electric power generation. The system may also include a seawater desalination apparatus which desalinates seawater by using hot water discharged after heat exchange through the cooler. The system may further include a water electrolysis apparatus which receives fresh water produced by the desalination apparatus and a heat source discharged therefrom to use the fresh water and heat source for producing hydrogen. A part of a heat source discharged from the water electrolysis apparatus after the production of hydrogen may be heat-exchanged with the cooler, and heat-exchanged with the heat source discharged from the desalination apparatus.

  • Publication number: 20220169535
    Abstract: This application relates to an adsorption desalination system using a multi-effect evaporator apparatus. In one aspect, the system includes a multi-effect evaporator apparatus producing high-temperature vapor and low-temperature vapor, a plurality of reaction units including an adsorbent adsorbing or desorbing moisture from the high-temperature vapor and low-temperature vapor and a heat exchange tube transferring heat to the adsorbent. The system may also include a condenser condensing vapor containing moisture desorbed from the adsorbents, and cold-hot water lines selectively supplying chilled water and hot water to the heat exchange tubes.
