By means of the solar energy supply device, by converting solar into hydrogen energy and recovering waste heat at the user side, the hydrogen energy can be converted into electricity energy and the waste heat can be recovered when users use electricity, so that the instantaneity of electric power supply and the high efficiency and stability of comprehensive utilization of the solar are ensured.

Description

technical field [0001] The application belongs to the technical field of clean energy supply, and in particular relates to a solar energy supply device. Background technique [0002] Based on energy and environmental considerations, countries around the world give priority to renewable energy and new energy for energy use, but due to the characteristics of various energy sources, more fossil energy has to be used in actual use. Among new energy and renewable energy, water energy, solar energy and wind energy account for the largest proportion of development and use, and most of them are power generation. [0003] Considering the efficiency of electric energy conversion, the country is now vigorously developing energy in areas and industries with large demand for cooling and heating to achieve combined cooling, heating and power supply, and the output power is determined based on the cooling and heating demand. Through the use of waste heat, the natural gas combined cooling,...

AI Technical Summary

Problems solved by technology

Solar thermal power generation adopts a large-scale high-temperature power generation system built in a large area, which is generally far away from the energy demand side, and needs to consider power transmission issues, and only uses the high-temperature section of the working fluid cycle, so heat dissipation, photothermal efficiency, and attenuation efficiency of selective absorbing coatings And other problems lead to the overall low power generation efficiency, and it is far away from the user end, and cannot output cold and heat. At the same time, the exhaust steam section of the steam turbine at the biggest energy loss end cannot be used, resulting in low overall utilization efficiency of solar energy.
