Abstract

The invention belongs to the field of solar energy application, and particularly relates to an efficient thermal evaporation seawater desalination device. The device comprises a concentric double-layer container and a conical top cover, the concentric double-layer container comprises an outer-layer evaporation cavity and an inner-layer fresh water cavity, a photo-thermal conversion film is arranged in the outer-layer evaporation cavity, and when a seawater desalination device is closed, a conical end of the top cover is aligned with the fresh water cavity. By redesigning the overall structureand distribution of the self-driven thermal evaporation seawater desalination device, the moving path of water vapor and water is greatly optimized, the internal heat exchange and utilization of the device are improved, and the fresh water collection efficiency is improved. The device has the advantages of clean energy utilization, sustainable fresh water resource generation, high efficiency and low cost.

Description

technical field [0001] The invention belongs to the field of solar energy application, in particular to a high-efficiency thermal evaporation seawater desalination device. Background technique [0002] Due to the geographical environment and climate, some coastal areas and islands are short of fresh water resources, making it difficult for humans to live and live for a long time. In addition, it is difficult to meet the distributed water demand of coasts and islands by building large-scale seawater desalination plants or laying long-distance water pipelines. [0003] For low-latitude regions, they often have stable light hours and abundant solar energy resources. Fresh water can be obtained by heating seawater by sunlight and collecting and condensing the resulting water vapor. However, the natural evaporation efficiency is extremely low. In order to solve this problem, a large number of light-to-heat conversion materials (ie, light-to-heat conversion films) that can captu...
