DESALINATION METHOD

摘要

A desalination method disclosed herein includes: introducing a liquid to a reservoir layer to place the liquid above a water-repellent particle layer; heating and evaporating the liquid placed above the water-repellent particle layer to generate water vapor; liquefying the water vapor by a liquefying layer to obtain fresh water; determining whether or not impurities have been deposited on a sheet; and removing the sheet from a desalination apparatus if it is determined that the impurities have been deposited.

1. A desalination method for obtaining fresh water from a liquid using a desalination apparatus that obtains fresh water from a liquid in which impurities are dissolved, the desalination apparatus including:
a water-repellent particle layer that is located below a reservoir layer, contains a plurality of water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the reservoir layer, the reservoir layer being a space for storing the liquid; a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water; and a sheet that is disposed in a surface portion of the water-repellent particle layer, and has water permeability; the desalination method comprising: introducing the liquid to the reservoir layer to place the liquid above the water-repellent particle layer; heating and evaporating the liquid placed above the water-repellent particle layer to generate water vapor; liquefying the water vapor by the liquefying layer to obtain the fresh water; determining whether or not the impurities have been deposited on the sheet; and removing the sheet from the desalination apparatus if it is determined that the impurities have been deposited.
