DESALINATION METHOD AND DEVICE FOR WATER CONTAINING SALT AND THE LIKE, AND FLOATING POROUS CARRIER USED FOR THE DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a method and device for efficiently desalinating water containing salts and the like at a low cost using a simple structure and solar heat, and a floating porous carrier used for the device. PSOLUTION: A dome-shaped closed container 2 is installed on the surface of the water 1 containing salts and the like so as to close the water surface. Floating porous carriers 3 are floated on the water surface closed by the dome-shaped closed container 2, and are moved by wave power to form thin films of the water containing salts and the like on the surface and in the inside of each carrier 3. Evaporated and condensed water in the dome-shaped closed container 2 is recovered along the inner wall of the closed container 3. It is desirable that the upper part of the dome-shaped closed container 2 has a moderate slant so that the evaporated water convects and the condensed water is introduced into a condensed water recovery tank 4 at the edge of the closed tank 3.
