Application of compressed air foam rapid supply technology in fire fighting of super high-rise buildings

介绍了压缩空气泡沫的灭火效能及在超高层建筑灭火的优势,叙述了压缩空气泡沫灭火系统构成及压缩空气泡沫快速输送技术在超高层建筑的试验,阐述了管径静压与试验时间的关系,给出了向下输送压缩空气泡沫的出泡沫时间及建立压力时间、单车/双车输送压缩空气泡沫静压值、单车/双车输送压缩空气泡沫出泡沫时间等试验曲线,提出超高层建筑压缩空气泡沫快速输送系统设计建议,为解决超高层建筑灭火难题提供新途径。

This paper first introduces the fire extinguishing efficiency of compressed air foam and the advantages of fire extinguishing in super high-rise buildings,describes the composition of compressed air foam fire extinguishing system and the rapid supply technology of compressed air foam in super high-rise buildings,expounds the relationship between the static pressure and the test time,and gives out the foaming time for downloading compressed air foam and the establishment of pressure time,single/double vehicle supply.The design curves of compressed air foam rapid conveying system for super high-rise buildings are put forward,such as sending compressed air foam static pressure value,single/double vehicle supply compressed air foam foaming time test curve,and so on,which provides a new way to solve the problem of fire extinguishing for super high-rise buildings.
