Description

technical field [0001] The invention belongs to the technical field of solar distillation and water treatment, and in particular relates to a solar distillation device and a water body purification method based on interface evaporation. Background technique [0002] The traditional solar distillation is mainly through the introduction of concentrators to increase the temperature of the evaporated water, the introduction of solar collectors to increase the light-to-heat conversion rate, and the introduction of multi-effect condensation surfaces to reuse the latent heat of condensation, which is a relatively common practice. However, the main disadvantages of traditional solar distillation are low photothermal conversion efficiency, low water production, large and complex device structure. With the existing solar energy interface distillation device, with the distillation of the water body on the interface evaporation platform, impurities in the water body will be deposited on...

However, the main disadvantages of traditional solar distillation are low photothermal conversion efficiency, low water production, large and complex device structure

With the existing solar energy interface distillation device, with the distillation of the water body on the interface evaporation platform, impurities in the water body will be deposited on the interface evaporation platform. When the interface evaporation material needs to be replaced is also a problem that needs to be solved, which will not cause waste and ensure The purity of the distilled water; the treatment method when the water delivery efficiency on the interface evaporation platform is insufficient and the water volume is too much is also a problem that needs to be solved
