TECHNICAL FIELD

[0001] The utility model relates to the technical field of solar energy, especially to a multi-energy complementary thermoelectric energy storage and supply system. BACKGROUND

[0002] The key parts of the locomotive are disassembled and cleaned and maintained, which is an essential link for locomotive overhaul. Locomotive cleaning and manufacturing will consume a large amount of energy and cause a large amount of carbon dioxide emissions, so new solutions are urgently needed.

[0003] In addition to the traditional coal-fired boiler steam production technology, there are many renewable energy technologies for producing high-temperature water or steam at home and abroad. Xiaobin Gu et al. proposed a phase change material (PCM) integrated solar steam generator and a new strategy, which can effectively solve the problem of solar intermittency, improve the interface solar steam production, and use heat storage technology to produce solar steam all day. Yue Bian et al. proposed a solar thermal photovoltaic steam generator (STPV), which uses infrared photons as a heat source to produce stable steam. Studies have shown that compared with traditional solar steam generators (STVs), evaporation efficiency and stability have been greatly improved. Yeran Li et al. designed a new type of bionic blade, which is composed of hydrophilic polyvinyl alcohol and micro-nano porous hydrophobic surface layer and other materials. Experiments show that the steam generator based on the bionic blade structure realizes a high evaporation rate of 3.09kg / m 2 ·h under one-time solar irradiation (1kW / m 2 ). 2 Xiuqiang Li et al. optimized the structure of the environmental energy enhanced interface solar evaporator, and the solar steam generator device will have a net energy gain from the environment, resulting in an evaporation rate exceeding the theoretical value. Han Jingyang et al. studied the effect of external reflectors on solar heat collection and steam production, calculated the solar radiation energy received in different seasons, azimuth angles and reflector inclination angles, and studied the performance characteristics of the steam production device. The results show that when the solar irradiance reaches 1000W / m 2 , the highest steam production rate of the device with external reflectors is 2.5 times that of the device without external reflectors, and the daily steam production increases from 8.18kg to 12.6kg.

[0004] Julien et al. successfully developed a dynamic numerical model for simulating a solar water heating system designed by them. The system aimed to supply hot water over 80℃ to a small calf farm twice a day, which was composed of 16 evacuated-tube solar water heaters connected to a non-pressurized water tank by thermosyphon effect. Its uniqueness was the alternating use of series and parallel solar collectors layout to achieve preheating and storage of hot water. The solar system accounted for 60% of the energy demand during the production cycle. Luotongtong et al. successfully introduced a solar water heating system into industrial production by preheating with solar energy and using an electric boiler as a guarantee for the final temperature. The system included a water softening device, a solar collector and a non-pressurized electric boiler, etc. to ensure that 20 tons of water were treated every day, and the outlet water temperature was maintained at 95℃. Wangye et al. conducted numerical analysis on fluid flow and heat transfer in different thermal storage water tanks based on a solar water heating system as the engineering background, and obtained the best water tank structure at each time and the corresponding optimal operating parameters. The research results have important engineering guiding significance for promoting the use of multiple water tanks for alternating operation in solar heating systems to improve heating reliability.
