Title:
PASSIVE ALL-WEATHER INTEGRATED SOLAR WATER DESALINATION AND CONDENSATE COLLECTION EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2022/178926
Kind Code:
A1
Abstract:
Disclosed is passive all-weather integrated solar water desalination and condensate collection equipment, comprising an evaporation unit, a condensation unit, and a water collection unit. The evaporation unit comprises an evaporation pond and a sunlight selective absorption heater. The sunlight selective absorption heater is located inside the evaporation pond, the absorption rate of the sunlight selective absorption heater in a sunlight band is greater than 80%, and the absorption rate thereof in mid-infrared bands other than sunlight is less than 20%. The condensation unit adopts a mid-infrared light selective radiation material or structure, covers the evaporation unit, and is used for transmitting sunlight and radiating mid-infrared light. The water collection unit comprises internal water collection channels and external water collection channels. The internal water collection channels are located at the periphery of the inner bottom of the condensation unit and used for collecting condensed water gathered in the evaporation pond. The external water collection channels are located at the periphery of the outer bottom of the condensation unit and used for collecting condensed water gathered in the air. The present invention integrates solar water desalination and condensed water collection, takes the advantages of the both, and is higher in fresh water yield, simple in structure, green and environment-friendly.
