Abstract

A desalination device includes a vessel, a breathable sheet, a water-repellent particle layer and a tank layer. The tank layer is positioned at the lower portion inside the vessel and the breathable sheet is interposed between the water-repellent particle layer and the tank layer. The breathable sheet includes a through-hole, the water-repellent particle layer is composed of a plurality of water-repellent particles, and the surface of the respective water-repellent particles includes a water-repellent film. The saltwater is desalted by a step of pouring saltwater into the vessel to dispose the saltwater on the surface of the water-repellent particle layer, a step of heating the saltwater to evaporate the saltwater into vapor; and a step of liquefying the vapor to obtain fresh water in the tank layer.
