摘要: 以七氟丙烷灭火剂为灭火介质,研究其在不同喷射方式下对磷酸铁锂储能电池火灾的灭火效果。研究发现:不同喷射方式均可在8 s 内扑灭明火,但灭火效果存在一定差异。七氟丙烷垂直喷射时,扑灭明火仅用2 s,且瞬时降温速率最大可达43 ℃/s。抑制复燃时间长,持续升温时间以及持续冒烟时间短。在喷射方式的选择上应尽量保证灭火剂喷口能够覆盖在电池正上方,这样能够最大化发挥七氟丙烷的灭火效果。

Abstract: Heptafluoropropane was used as extinguishing agent to research the fire extinguishing effect on fire of lithium iron phosphate energy storage battery under different injection modes. It is found that all modes of injection can extinguish open flames within 8s, but the extinguishing effect is different. When heptafluoropropane is sprayed vertically, it only takes 2 s to extinguish open flames, and the instantaneous cooling rate can reach 43 ℃/s at most. The suppression time of reburning is long, the duration of temperature rising and the duration of smoking are short. The extinguishing agent nozzle should coverup of the batterydirectly to maximize the extinguishing effect of heptafluoropropane of injection mode.

Key words: Lithium iron phosphate battery, heptafluoropropane;fire extinguishing method, suppression of reburning
