空运锂离子电池火灾探测方法研究

Research on the lithium-ion battery fire detection during air transportation

通过自主设计的电池燃爆实验平台,实验研究不同类型锂离子电池火灾初期发展过程。重点研究初爆和二次燃爆后环境温度及气体成分,指出飞机货舱现有感烟火灾探测装置对锂离子电池燃爆初期探测效果不明显,分析可燃气体火灾探测对锂离子电池火灾初期探测的优势。基于航空器适航要求,提出将气体探测和灭火装置集成于独立的集装器内用于锂离子电池火灾探测和控制的方法。

Established a lithium- ion battery combustion experi- ment platform, experimentally analyzed the different type lithi- um ion battery fires in the early development process, especially the environment temperature and gas composition after initial blast and secondary combustion, and then point out that the ex- isting aircraft cargo hold smoke detection device for lithium-ion battery early fire detection effect is inefficient. The advantage of combustible gas fire detection for lithium-ion batteries early fire detection was analyzed. In view of the aircraft airworthiness requirements, proposed a detection and extinguishing equipment integrated practical method in separate storage transport con- tainers.
