Description
Technical Field
The invention relates to the fields of seawater desalination, photothermal conversion and the like, and relates to a portable seawater desalination distiller with high solar energy and high photothermal conversion rate and a method.
Background
Seawater desalination is an effective method for solving global fresh water shortage and insufficient fresh water supply in islands and coastal areas, and is rapidly popularized due to wide sources of seawater and brackish water and mature desalination technology. The traditional seawater desalination plant mainly adopts a reverse osmosis method and a low-temperature flash evaporation method, is driven by non-renewable energy sources such as consumed electric energy, coal and the like, has the characteristics of large scale, large occupied area, huge capital requirement and the like, is not suitable for part of application scenes, and is particularly embodied in the fields of offshore emergency lifesaving, ship disaster recovery and the like; islands, offshore platforms, beaches, remote towns and other areas. The application environment and the region require that the seawater desalination device only uses energy sources in natural environment, such as solar energy, wind energy or manpower, and the like, and does not depend on electricity, diesel oil and the like, and a solar distiller which uses sunlight as the energy source and desalts seawater by a thermal distillation method is very suitable for the demand.
The solar seawater desalination technology can utilize renewable solar photo-thermal resources in the regions to heat seawater, and fresh water is obtained by condensing and collecting the seawater after phase change evaporation. The solar distiller technology is the mainstream solar seawater desalination technology at present, and has the advantages of high efficiency, low cost, simple maintenance and the like. Therefore, research and development of small distributed or portable solar seawater desalination equipment and system are expected to provide sufficient and cheap fresh water for life production, military, outdoor sports, field scientific investigation and exploration of residents in the areas, and the energy conservation, low carbon, economy and environmental protection of the seawater desalination technology are realized.
At present, the seawater desalination efficiency of the portable solar distiller is only 10-25%, and the performance of the portable solar distiller is doubled compared with the efficiency of a non-portable solar distiller. This is because the portable equipment needs to not only consider the solar energy conversion efficiency, but also achieve the economical efficiency and portability of the equipment, including the properties of light weight, folding, and easy assembly, and thus cannot handle the structure and materials of the large-scale solar seawater desalination plant. In particular, the transparent condensing glass cover plate component in the large-scale solar seawater desalination equipment has high price, high density and can not be folded, and is not suitable for being used as a condensing cover plate component of portable equipment; and the heat insulation foam part in the equipment can reduce the effective illumination area if being applied to small-sized portable equipment, and has the defects of easy aging and corrosion and incapability of folding. In the traditional portable distiller research, an effective heat insulation component is abandoned, and non-negligible system-environment heat loss is brought; and light materials such as a high molecular film or organic glass are selected as the light-transmitting condensing part, but due to the hydrophobicity of the surface of the light-transmitting condensing part, water drops form fog-shaped liquid drops on the condensing surface, so that the light scattering rate is greatly increased, and the sunlight utilization rate is reduced. Therefore, in order to improve the seawater desalination efficiency of the portable solar distiller, the heat utilization and optical utilization performance of all parts of the equipment need to be improved on the basis of light weight, portability and easy folding.
