Abstract

The invention provides a solar energy distillation apparatus. The solar energy distillation apparatus comprises a liquid holding structure, a photothermal conversion structure, a condensation structure, and a liquid collection structure. The liquid holding structure includes an accommodating cavity. The accommodating cavity is for accommodating a liquid to-be-distilled. The photothermal conversionstructure is disposed in the liquid holding structure. The photothermal conversion structure is a multilayer spiral cone structure. The photothermal conversion structure includes a permeable base layer and a photothermal material layer with laminated arrangement with the permeable base layer. The photothermal material layer is configured to absorb light energy to heat the liquid to-be-distilled absorbed by the permeable base layer to vapor. The condensation structure is disposed in a steam flow direction for condensing the vapor into distilled water. The liquid holding structure is disposed adjacent to the condensation structure. The liquid collection structure is used to collect the distilled water.

Description

technical field [0001] The present application relates to the field of photothermal conversion, in particular to a solar distillation device. Background technique [0002] With the development of economy, water pollution is becoming more and more serious. The scarcity of fresh water resources has become one of the most serious challenges in the world. Seawater desalination has attracted people's attention as a clean and sustainable way to obtain fresh water. Using solar energy to directly evaporate seawater is an effective method for seawater desalination and desalination, and this method does not require additional energy supply, and meets the requirements of energy saving, emission reduction and sustainable development. [0003] However, in traditional water distillation, since sunlight cannot be fully absorbed by the photothermal conversion structure and there is a certain heat loss in the photothermal conversion structure, the photothermal conversion efficiency and wat...
