摘要:

以压缩空气泡沫为灭火剂进行试验,通过理论分析和实体火灾试验,对压缩空气泡沫扑救锂离子电池火灾的灭火和抗复燃性进行研究。试验结果表明,压缩空气泡沫对锂离子电池火灾可以快速灭火、持续降温,并对可燃气体进行吸收,长期淹没锂离子电池可以起到有效抗复燃的作用。对短期与长期不同时长的抑制结果进行分析对比,长期有效时长可达 48 h 以上。

Abstract:

The compressed air foam was used as the fire extinguishing agent to carry out experiments. Through theoretical analysis and physical fire tests, the extinguishment and anti reburning properties of compressed air foam for fighting lithiumion battery fires were studied. The test results show that the compressed air foam can quickly extinguish the lithium-ion battery fire, keep the temperature down, and absorb the combustible gas. Long term immersion in the wrapped lithium- ion battery can effectively resist the re ignition. The results of shortterm and long- term are analyzed and compared, and the longterm effective length of time can reach more than 48 h.
