Abstract
The invention discloses a miniaturized low-power condensation multistage seawater desalination system which comprises a condenser, the condenser is perpendicular to sunlight, a light outlet of the condenser is provided with a photo-thermal conversion layer, a capillary wick is arranged on the back face of the photo-thermal conversion layer, a plurality of stages of evaporation and condensation devices are arranged on one side of the capillary wick, each stage of evaporation and condensation device comprises a condensation plate and a capillary wick, and the capillary wick is arranged on the back face of the condensation plate. And the bottom end of the capillary wick extends into seawater. According to the invention, latent heat is recovered step by step, so that the theoretical water production rate limit of a traditional floating type seawater desalination system can be broken through, the problems of low water production rate, low efficiency and difficulty in collecting desalted water of the existing floating type seawater desalination system are solved, and the floating type seawater desalination system has the advantages of large water yield and suitability for remote areas.
