Sea-level floating type solar energy desalting kit

Abstract

The invention belongs to the technical field of solar energy utilization, and particularly relates to a solar energy desalting kit. The sea-level floating type solar energy desalting kit is arranged on a sea level, and adopts the technical scheme that reflecting condensing surfaces (4) adopt a non-planar structure, and are mounted on a baseplate (8); high-reflectivity coatings are plated on the surfaces of the reflecting condensing surfaces (4); fresh water outlet pipes (6) are arranged at the bottoms of the reflecting condensing surfaces (4); a supporting rack (2) is mounted on the baseplate (8) on the periphery of the reflecting condensing surfaces (4); a hydrophilic cellular material is adhered to the outer side of the supporting rack (2); a transparent film (1) is arranged at the top of the supporting rack (2); orthographic projection of the transparent film (1) covers the reflecting condensing surfaces (4) and the baseplate (8); seawater inlets (7) are further formed in the baseplate (8), formed in the outer side of the fresh water outlet pipes (6), and separated from the fresh water outlet pipes (6) through a water baffle (5). According to the invention, sunlight can be directly utilized to generate fresh water.

Description

technical field [0001] The invention belongs to the technical field of solar energy utilization, and in particular relates to a solar energy desalination device. Background technique [0002] There are many methods for extracting fresh water from seawater. At present, there are two mature technologies: reverse osmosis membrane method and distillation method. [0003] The reverse osmosis membrane method has defects such as large one-time investment and the need to consume conventional electric energy, which is contrary to the current concept of energy saving and environmental protection. Another heat-driven seawater desalination distillation method is currently the most mature and is the mainstream of today's seawater desalination industry. However, this system often needs to consume a lot of heat energy. In addition, the system also works under vacuum and negative pressure, so it also needs a shell material with strong strength and good corrosion resistance, which increases...
