Abstract

Based on the marine drilling platform or the freshwater shortages of barren island that need to be developed, the paper proposes a new type of energy saving through the wave energy device to manufacture freshwater. The wave energy of the sea can be converted into the negative pressure of the system through the marine float, the intermediate transmission device and negative pressure device, and it can lower the temperature of evaporation and saturation of seawater that are to be desalinated, and reduce heat energy which is needed to evaporate seawater, so as to achieve the purpose of energy saving.First, this paper set up a thermodynamic model of the device, then the mathematical model of the whole system in the steady state according to each device in the system. Through the simulation, the relationship between freshwater yield of wave energy seawater desalination system of and the location of the sea shows that the device can be more efficient for seawater desalination and basically meet the needs of offshore drilling platform on water demand with good economic benefit and the energy-saving effect.
