Description
Technical Field
The invention belongs to the field of solar photo-thermal application, and particularly relates to a beach shower based on a solar photo-thermal film technology.
Background
For a beach bathing place, a shower is a necessary cleaning facility for people to clean dirt such as salt, sand and the like on the body after swimming or beach sports. However, most of the existing bathing facilities in the beach bathing place are supplied with tap water, and a large amount of water is consumed in the operation process, thereby causing water resource waste. Although secondary water after sewage treatment is gradually adopted as shower water supply in part of areas, the cost is still high; and because the secondary water may also contain more impurities and pollutants, the popularization is not recommended.
Although there is a related design that solar energy is used for power generation, seawater is heated through electrothermal conversion, and fresh water is collected through distillation, the sunlight utilization rate is extremely low due to multiple times of energy conversion, and the energy is further wasted due to the overall heating of water in the distillation process. In recent years, a photothermal film-based solar thermal evaporator taking a photothermal film as a core can effectively utilize sunlight, under the illumination condition, solar light energy is efficiently converted into heat energy through single energy conversion, the surface of seawater is directly heated, high-speed and efficient evaporation of water is realized, and clean fresh water is directly separated from seawater. The photo-thermal film applied to the field of solar drive water evaporation at the present stage mainly comprises the following materials: 1. carbon-based materials including carbon nanotubes, graphene, activated carbon, and the like; 2. metal nanomaterials including noble metals such as gold, silver, palladium, etc.; 3. transition metal oxides including titanium oxide, titanium oxide and spinel structure materials; 4. high molecular polymers including polydopamine and polyaniline derivatives. By regulating and controlling the composition, microstructure and surface wettability of the membrane material, the light capture performance, water transmission performance and heat collection performance of the photo-thermal membrane are optimized, so that efficient interfacial water evaporation is realized. Most of the photo-thermal films reported in the prior art have the light absorption rate of over 95 percent, and the solar photo-thermal conversion efficiency for water evaporation generally exceeds 80 percent. Through the construction of a macroscopic structure and a heat insulation layer, the sunlight-heat conversion efficiency can exceed 90 percent and is far higher than the total light-electricity-heat conversion efficiency in solar heating, and the sunlight-heat conversion device has better economic value and practicability.
Because the whole process uses sunlight as energy, the method has ideal environmental friendliness and sustainability, and the operation cost is obviously lower than that of tap water supply required by the traditional shower. The shower facility taking solar photothermal evaporation based on the photothermal film as a core is suitable for being arranged in a beach bath field to be used as a cleaning facility.
