Abstract

The invention relates to an amino thermochemical high-temperature energy storage method, which includes using the amino thermochemical reversible reaction 2NH3+△HN2+3H2 to store energy through conversion of thermal energy and chemical energy; when heated by solar thermal energy, high-temperature thermal energy, waste heat or waste heat , the liquid NH3 in the amino endothermic reactor undergoes an endothermic decomposition reaction under the action of a catalyst and high pressure, and the received heat is stored in the gaseous decomposition products N2 and H2 in the form of chemical energy; when heat is needed, N2 and H2 Input into the exothermic reactor, under the action of catalyst and high pressure, a reverse thermochemical reaction occurs, and the chemical energy stored in N2 and H2 is reversed into high-grade heat and released. The invention also relates to devices used in said method.

Description

technical field [0001] The invention relates to a high-temperature energy storage method and device for high-temperature thermal energy conversion storage and thermal regeneration, in particular to a method for converting solar thermal energy into chemical energy and storing it in a reaction medium. The method reverses chemical energy into heat and releases it so as to obtain high-grade heat energy, an amino thermochemical high-temperature energy storage method and a device thereof. Background technique [0002] In various energy systems and industrial processes, due to the imperfection of energy conversion and utilization and the limitations of heat sinks, there are waste heat and waste heat at various temperature levels, and the unused high-temperature waste heat resources are widely distributed. At the same time, the reserves of traditional primary energy such as coal, natural gas, and oil are very limited, but solar energy resources are very rich....
