A solar heat collection seawater desalination device with hydraulic telescopic driving mirror

Abstract

The invention provides a solar heat collection seawater desalination device, the device includes a water tank and a light-to-heat conversion element, the upper end of the water tank is an open structure, the light-to-heat conversion element floats on the upper part of the water tank, and the light-to-heat conversion element includes The matrix formed by foaming material forms a groove with an upper side opening, the groove is filled with a foamed nickel matrix, and the lower wall of the matrix is ​​provided with a capillary structure water delivery channel, and the water delivery channel communicates with the water body of the water tank and the foamed nickel The substrate, the upper part of the groove is provided with a light-to-heat conversion coating, and the light-to-heat conversion coating is connected to the foamed nickel substrate, and the buoyancy of the foamed material itself is greater than gravity. The invention generates a large amount of steam without the assistance of a heating device, and the floating foam material lifts the light-to-heat conversion layer out of the water surface, inhibiting the dissipation of the generated heat energy from the film to the liquid in the lower layer, thereby improving the vaporization efficiency of the device, and showing its advantages It has great potential as a new energy material for photothermal conversion.

Description

Technical field [0001] The invention belongs to the solar field, in particular to a solar collector system. Background technique [0002] With the rapid development of modern socio-economic economy, human demand for energy is getting bigger and bigger. However, traditional energy reservations such as coal, oil, natural gas is continuously reduced, increasing, resulting in rising prices, and the environmental pollution problems caused by conventional fossil fuels are more serious, and these are greatly limited to the development of society and the improvement of human life. . Energy issues have become one of the most prominent issues of contemporary world. Therefore, new energy, especially non-polluting cleaning energy has become a hot spot in people's research. [0003] Solar can be an inexhaustible clean energy, and the amount of resources in the Earth's surface is 1 × 10 18 KW · h, for the total annual energy of the world, more than 10,000 times. All countries in the world have...

Problems solved by technology

[0007] There are more than 10,000 islands in China, but most of them are uninhabitable due to lack of fresh water, and there are less than 500 permanent residents, which restricts the functions of island development and national defense.
