AI Technical Summary

Technical Problem

Existing seawater desalination technologies cannot directly utilize renewable energy sources, resulting in problems such as high energy consumption and large carbon emissions.

Method used

The dew point evaporation technology driven by solar energy combines a solar pool and a dew point evaporator. Seawater is stored in the solar pool and spontaneously stratified by salinity and temperature gradients to form an upper troposphere, a non-troposphere, and a lower troposphere, achieving low-temperature evaporation and heat storage. Combined with components such as dust collectors, fans, regenerators, and coolers, a seawater desalination system is formed.

Benefits of technology

It achieves low-carbon and green freshwater production, improves water production efficiency and thermal efficiency, reduces heat loss, and can operate normally both day and night without the need for additional heat storage devices.
