3D printed solar evaporator

Recently, Song Yanlin, a researcher at the Green Printing Laboratory of the Institute of Chemistry, Chinese Academy of Sciences, used 3D printing technology to construct a three-dimensional cone-shaped asymmetric structure evaporation system in the early stage to realize the basis for efficient solar energy utilization and high water evaporation under high salinity.
Above, the bridge-arch solar evaporator is further designed to realize the one-step preparation of the evaporator, which has excellent weather resistance and long-term salt resistance under high salinity
.

A double-layer continuous water film is formed on the surface of the evaporator.
The lower confinement layer is used to maintain the continuity of the water film to quickly replenish the liquid.
The Marangoni convection caused by the temperature gradient in the upper layer can inhibit the accumulation of salt in the high temperature area, and realize Stable salt discharge for a long time
.
Even if the evaporator uses high-salinity salt water to evaporate continuously for 200 hours, no salt is analyzed on the surface of the evaporator, which provides a new strategy for realizing automatic continuous seawater desalination
