Chemical-looping continuous oxygen production system and method based on solar photothermal

Abstract

The invention provides a chemical-looping continuous oxygen production system based on solar photothermal, and belongs to the technical field of chemical-looping oxygen production of solar heat storage and heat accumulation. The system comprises a Fresnel lens field, a heat storage device, a side steel plate, an end steel plate, a columnar glass body, a lifting gate, a premixer, a fan, an air preheater, a reheater, a condenser, a superheater, an evaporator and an oxygen production device. The chemical-looping oxygen generation system is coupled with the solar photo-thermal heat storage system,hot air absorbs solar photo-thermal and then generates steam and performs oxygen absorption and desorption reaction, and then high-temperature oxygen-poor air generated by the reaction preheats coldair. Superheated steam and oxygen mixed gas obtained after the oxygen release reaction is subjected to condensation treatment after air is subjected to secondary heating to obtain pure oxygen, and preheated air enters a heat storage device to be subjected to convective heat exchange to form high-temperature air to continue to participate in the circulation. The whole system realizes gradient utilization of energy, achieves the purpose of low-energy-consumption oxygen production, and conforms to the modern theme of energy conservation and emission reduction.
