摘要:
针对大型浮顶罐罐壁式泡沫灭火系统的特点及不足,依据相关规范要求设计了30m长的密封圈火灾模拟试验油槽,开展了3%型水成膜泡沫液和6%型氟蛋白泡沫液灭火试验。现场测定了泡沫的发泡倍数和析液时间,符合规范要求但略低于检测值。试验过程测定了泡沫在泡沫堰板内的流动速度和燃烧油面的蔓延速度,观察了不同的泡沫液和泡沫混合液供给强度下的油槽火灭火状况,对比分析了油槽火周邻的温度和热流分布。在此基础上,评估分析了罐壁式泡沫系统扑救密封圈火灾的有效性。试验结果表明:有效的泡沫混合液供给强度下,3%型水成膜泡沫和6%型氟蛋白泡沫可控密封圈火灾,甚至灭火;泡沫类型和泡沫混合液供给强度对油槽火全淹没时间的影响较大。该试验对大型浮顶罐低液位密封圈火灾扑救具有积极的指导意义和工程应用价值。
Abstract:
According to the characteristics and shortage of tankshell fire fighting system of opentop large floating roof oil tanks, an experiment oil groove of rim seal fire with 30 meters long was designed by the related code, and some foam extinguishing experiments of 3% aqueous filmforming foam concentrate (AFFF) and 6% fluoroprotein foam concentrate (FP) were conducted. In the experiment process, foam expansion ratio and 25% drainage time of 3%AFFF and 6%FP were tested on spot, and accorded with the standard of fire extinguish agent, but were both less than testing report value of lab. Moreover, foam flow speed in the foam weir plate and overspread rate on the fire oil surface were determined, and oil fire development condition was observed and recorded. The temperature and heat flow of oil groove fire were contrasted and analyzed with different foam and application rate of foam solution. Furthermore, the effectiveness of tankshell foam extinguishing system of opentop large floating roof oil tanks for rim seal fire was descried and discussed. The test results showed that 3%AFFF and 6%FP may control and extinguish even the rim seal fire with the effective application density of foam concentrate, and foam type and application density have important effect on the time of total flooding oil surface. This experiment has some positive reference and engineering application value for foam extinguishing rim seal fire of large floating roof oil tanks with low liquid level.
