The invention discloses a solar thermal chemical energy storage system based on heat recovery of a self-thermal ammonia synthesis reactor. The solar thermal chemical energy storage system comprises a heliostat field, an ammonia decomposition reactor, a normal-temperature pressure storage tank, a self-heat recovery synthesis reactor and a turbine, the normal-temperature pressure storage tank is provided with a first infusion pipe, a second infusion pipe, a first gas delivery pipe and a second gas delivery pipe, the first liquid delivery pipe is connected with a liquid inlet of the ammonia decomposition reactor, and the first gas delivery pipe is connected with a gas outlet of the ammonia decomposition reactor; and the second liquid delivery pipe is connected with a liquid outlet of the self-heat recovery synthesis reactor, and the second gas delivery pipe is connected with an air inlet of the self-heat recovery synthesis reactor, the self-heat recovery synthesis reactor is connected with the turbine through a first guide pipe and a second guide pipe. The system has the beneficial effects that due to the fact that the self-heat recovery synthesis reactor is arranged, only a small amount of catalyst amount is needed to complete the heating working fluid and the preheating feeding gas, so that the use amount of the catalyst is reduced.
Description
technical field [0001] The invention relates to the technical field of energy storage power generation equipment, in particular to a solar thermochemical energy storage system based on heat recovery from a self-heating ammonia synthesis reactor. Background technique [0002] Solar energy is an inexhaustible independent energy source. However, the intermittent nature of solar energy makes it difficult to maintain a constant power supply. Energy storage systems that can benefit from storage such as thermal energy storage, batteries and fuel cells, solar energy to provide dispatchable electricity. While fuel cells and batteries have the potential to increase efficiency at scale, thermal energy storage, as used in most commercial concentrated solar power plants, is more cost-effective and reliable. There are mainly three forms of thermal energy storage namely sensible heat, latent heat and thermochemical. Compared with other forms of energy storage, thermochemical energy stor...
