High-efficiency solar multi-layer evaporative seawater desalination device

Abstract

A high-efficiency solar multi-layer evaporative seawater desalination device includes a transparent housing. In the device, wedge-shaped recesses are formed on an outer wall of the transparent housing; during seawater desalination, seawater is injected into evaporation trays and sunlight is irradiated on the evaporation trays through the transparent housing; the transparent housing is made of a transparent plastic material, such that sunlight can directly enter the transparent housing and increase a temperature therein to speed up the evaporation; the wedge-shaped recesses are on a shady surface; during desalination, seawater in the evaporation trays absorbs heat and evaporates to form water vapor, such that there is a given temperature difference between the water vapor and the outside; and a lower part of the wedge-shaped recess can serve as a condensation surface, the water vapor condenses on the transparent housing or at the wedge-shaped recess.
