Abstract

The invention discloses a micro-cavity type solar seawater desalination unit based on condensation, belonging to the technical fields of solar heat collection, seawater desalination and water treatment. The micro-cavity type solar seawater desalination unit is composed of a shell, a triangular prism condenser, an evaporation chamber, a condensation chamber, a transparent plate, a porous matrix plate, a water absorbing material and a water storage tank. A plurality of the micro-cavity type solar seawater desalination units can be arrayed together and floated on a large area of a sea surface for usage. The micro-cavity type solar seawater desalination unit allows seawater to rise to the area of the evaporation chamber via the water absorbing performance of the water absorbing material; sunlight is gathered to the area of the evaporation chamber via the triangular prism condenser to produce heat energy, so seawater evaporation is realized; water vapor enters the condensation chamber via air vents and continuously exchanges heat with external cold seawater on the bottom and vertical walls of the condensation chamber, so fresh water is formed and stored in the water storage tank located at the bottom of the condensation chamber; and after accumulation, the fresh water can be supplied to users or be applied to offshore plant production.

Description

technical field [0001] The invention relates to a micro-cavity solar seawater desalination unit based on light concentration, belonging to the technical fields of solar heat collection, seawater desalination and water treatment. Background technique [0002] Solar energy is an extremely important green energy source, which is inexhaustible and has great utilization value. However, the shortage of fresh water resources per capita in our country and the problem of water pollution are becoming more and more serious. Saving and protecting water resources is not the only way to solve the shortage of water resources. The use of solar energy for seawater desalination is expected to become a new option, which has great national strategic significance. [0003] At present, there are many seawater desalination technologies. Traditional technologies include reverse osmosis, electrodialysis, and dew point evaporation. However, these methods have defects such as high cost, high energy ...
