Abstract

A chemical loop air separation oxygen-making device comprises an air reactor and an oxygen release reactor. The air reactor can store a first oxygen carrier in a reduction state. Air is injected intothe air reactor to carry out redox reactions between the air and the first oxygen carrier to convert the first oxygen carrier into an oxidation state. The oxygen release reactor is arranged in the airreactor and contains a second oxygen carrier in an oxidation state. The oxygen reactor can utilize the heat generated by the air reactor to convert the second oxygen carrier into a reduction state from the oxidation state to generate oxygen.

Description

technical field [0001] The invention relates to an air separation oxygen production technology, in particular to a chemical circuit air separation oxygen production device. The invention also relates to the chemical loop air separation oxygen production method of the chemical loop air separation oxygen production device. Background technique [0002] At present, air separation oxygen production technology mainly includes cryogenic distillation and pressure swing adsorption. Among them, although the low-temperature distillation method can produce high-concentration oxygen (99%), the production scale is large and the process is complicated, so the cost is extremely high. On the contrary, pressure swing adsorption is suitable for small and medium-scale production, but the energy consumption is higher and the oxygen purity is slightly lower (93%). [0003] Chemical looping combustion technology is a technology that combines high energy efficiency and can achieve carbon dioxide...
