摘要
为推进可持续能源的存储和利用,促进我国产业绿色低碳化发展,本文探讨了压气储能内衬洞室(LRC)气体泄漏的三大主要原因:结构裂缝、热力循环和材料渗透,并提出地下岩穴储气库复合式衬砌密封结构及其施工方法,有效提高了LRC系统的安全稳定性和运营寿命,为完善LRC设计理论、提高LRC存储效率、保障LRC结构安全提供一定指导。
The paper aims to guarantee the air-tightness of lined rock caverns(LRC)for compressed air storage caverns(CAES),thus promoting the utilization of sustainable energy and China’s industrial decarbonization.We discussed the effects of three common damages on the caverns,namely structural cracks,thermal cycling and material permeation.Then analyzed the mechanism of leakage from different causes.On this basis,solutions to ensure tightness are summarized.In particular,we proposed a compound lining sealing structure and its construction method for underground CAES rock reserviors,which enhanced safety and operational lifespan of LRC system.This work provides some guidance for improving the LRC design theory,improve storage efficiency,and guarantee structural safety.
