AI Technical Summary
Existing chemical loop hydrogen production devices suffer from problems such as gas cross-contamination, poor continuity, and nitrogen leakage diluting the products. Furthermore, they cannot effectively prevent hydrogen from mixing with air and causing explosions or cross-contamination of the products, which could affect product purity.
A hydrogen-oxygen environment isolation system is adopted, including a separation unit, a connection unit, and a buffer unit. The oxygen carrier is isolated, connected, and transported between the reduction reaction system and the oxidation reaction system through a pressure balance pipeline and control valves. Combined with pressure transmitters and level sensors, automated control is carried out to ensure pressure balance and continuous material transportation.
It achieves effective isolation of hydrogen and oxygen environments, avoids the safety risks of hydrogen mixing with air, improves the continuity of oxygen carrier delivery and product purity, reduces maintenance costs and operational difficulty, and is suitable for high-temperature and high-dust operating conditions in chemical chain hydrogen production systems.
