Development of Wind-Solar-Diesel-Battery Integrated Seawater Desalination Device

The development to seawater desalination technology of new energy is the valid way of solving the energy shortage and environmental pollution in coastal and islands areas. It is introduced in this paper with the components, design methods and operation analysis to the pluripotent coupling reverse osmosis (RO) seawater desalination devices focusing on the wind-solar complementary power generation. The operation results are shown that, the power generation system in the combination of wind, solar energy, diesel generator and battery could provide stable electric energy to the seawater desalination device, the water quality generated is superior to the standard of drinking water, which could guarantee the water and electric power in remote island area. The container is used in such devices as the carrier to be moved rapidly with supplying water in emergence. The significant practical significance is realized to the water supply and demand on islands, offshore platform and ships and other special areas.
