摘要
为了降低密闭空间中新能源电动汽车的火灾危险性,首先从新能源电动汽车火灾事故统计数据入手,分析并总结密闭空间内新能源电动汽车的火灾特点。随后通过FDS数值模拟软件,模拟计算了不同种类灭火系统(水喷淋、泡沫-水喷淋)对密闭空间新能源电动汽车火灾场景的适用性,结果表明:泡沫-水喷淋自动灭火系统可有效降低电动汽车火灾危险性。最后参考已有的标准规范和新能源电动汽车火灾方面的研究成果,对密闭空间消防系统设计提出了相应的改进建议。本研究对船舶动力用锂电池的消防安全管理具有指导意义。
In order to reduce the risk of new energy electric vehicles in the tunnel,the fire characteristics of new energy electric vehicles in the tunnel are analyzed and summarized from the statistical data of fire accidents of new energy electric vehicles.Subsequently,the applicability of different fire extinguishing systems(water spray and foam—water spray)to the new energy electric vehicle fire scenario is simulated by FDS numerical simulation software.The results show that the foam water sprinkling automatic fire extinguishing system can effectively reduce the fire hazard of electric vehicles.Finally,referring to the existing standards and specifications and the research results of new energy electric vehicle fire,the corresponding improvement suggestions for the design of tunnel fire protection system are put forward.This study has positive significance for the fire safety management of marine lithium battery.
