摘要： 为了研究不同气源压缩气体泡沫对低沸点易燃液体火灾的灭火效果，基于正压式多剂联用发泡装置，采用搭建的1 m2油罐火试验模型，分别考察不同压缩气体泡沫灭火剂的泡沫性能和抑制正戊烷火灾的能力，分析探讨适用于低沸点正戊烷燃料火灾扑救的最佳发泡气源方案。试验结果表明：在泡沫混合液供给强度为10 L/（min·m2）的条件下，压缩氩气泡沫、压缩氮气泡沫和压缩空气泡沫均可扑灭正戊烷火灾，具有良好的抗复燃性；二氧化碳与现有水成膜泡沫的兼容性差，产生了明显的消泡作用，25%析液时间仅为86 s，无法成功灭火；在相同试验条件下，压缩氩气泡沫的控灭火性能均为最佳，其90%控火时间为45 s，灭火时间为118 s。该项研究可为压缩气体泡沫系统在石油化工行业的工程应用提供技术支撑。

Abstract: In order to study the fire extinguishing effect of compressed gas foam with different gas sources on low boiling point flammable liquid fires, the fire extinguishing performance of compressed gas foam based on different types of gas on n-pentane fires is studied by an experimental model of a 1 m2 tank fire using a positive pressure multi-agent combined foaming device. The types of gas sources suitable for the n-pentane fuel with low boiling point are discussed. The results indicate that compressed argon foam, compressed nitrogen foam and compressed air foam can extinguish n-pentane fires and have good resistance to reignition under the condition that the foam solution foam application rate is 10 L/(min·m2)；carbon dioxide had poor compatibility with existing aqueous film-forming foam, resulting in significant defoaming effects, and the 25% liquid separation time was only 86 s, which was unable to successfully extinguish the fire; under the same test conditions, the fire control and extinguishing performance of compressed argon foam was the best, with a 90% fire control time of 45 s and an extinguishing time of 118 s. The research can provide technical support for the application of compressed gas foam system in petrochemical industry.
