新能源汽车地下空间火灾防控体系优化研究
Journal: Journal of Safety Science and Engineering DOI: 10.12238/jsse.v3i4.17873
Abstract
锂离子电池热失控引发的火灾具有高热释放、强毒烟气、快蔓延、复燃等特征,对地下车库消防救援构成挑战。现行消防技术标准主要针对燃油车火灾,存在针对性不足、内部控火效能低、外部救援支撑弱等问题。本文提出完善技术标准体系、优化防火分区与排烟系统、提升应急响应能力等对策,设计集高压细水雾、低压CO2与地面喷水为一体的多级联动自动灭火系统,并结合智能排烟与多传感器融合报警系统,为地下空间新能源汽车火灾防控标准修订和消防救援体系优化提供技术支撑。
