摘要:

“双碳”目标下,需要建设大量与“风”“光”等新能源配套的磷酸铁锂电池储能电站,但磷酸铁锂电池具有较大火灾危险性,其灭火措施研究尚不完善。全氟己酮灭火剂是一种新型哈龙和氢氟烃类灭火剂的优良替代品,对其是否适用于扑灭储能锂电池火灾并抑制其热失控存有争议。基于全氟己酮应用于磷酸铁锂电池火灾的既往研究成果,优化了全氟己酮气体应用于磷酸铁锂电池储能电池舱的灭火方式,采用“局部应用”与“全淹没”灭火方式相结合,通过模型试验验证了灭火效果并得出了相关设计参数,以工程案例详细论述了全氟己酮气体灭火系统在储能电池舱的应用方案。

Abstract:

In the context of carbon peak and carbon neutralization, renewable energy sources, such as wind and light, are gradually becoming the dominant energy sources. Energy storage facilities, primarily lithium iron phosphate batteries in prefabricated energy storage cabins, are required. However, lithium iron phosphate batteries with a high risk of thermal runaway are likely to cause great fire hazards. Although perfluoro-2-methyl-3-pentanone is an excellent substitute for halons and HFCs fire extinguishing agents, its suitability for extinguishing energy storage lithium battery fires and suppressing thermal runaway is debatable. A perfluoro-2-methyl-3-pentanone fire extinguishing method combining "local application" and "total submersion" is proposed based on some experimental results of perfluoro-2-methyl-3-pentanone applied to lithium iron phosphate battery fires. The fire-extinguishing mechanism is verified by model tests, and the relevant design parameters are obtained. An engineering case is used to discuss the application scheme of a perfluoro-2-methyl-3-pentanone fire-extinguishing system in a prefabricated energy storage cabin.

Key words: lithium iron phosphate battery, perfluoro-2-methyl-3-pentanone, prefabricated cabin, fire protection
