摘要: 针对高层、地下、大跨度等有限空间建筑在火灾发生后的灾害特点及其主要危险特性,结合实战需求,借助微细结构压缩空气泡沫灭火系统,利用粒径在100~200 μm区间内的高精度混合压缩空气泡沫体系对有限空间建筑内部的火势进行有效抑制,考察压缩空气泡沫灭火系统气液比、气液混合压力、气液混合速度等相关因素对有限空间建筑火灾处置过程中的实际影响。结果表明,压缩空气泡沫具有发泡充分、泡沫均匀细腻、稳定性好、灭火效能高、抗复燃能力强等优势特性,当压缩空气泡沫灭火系统气液比为6:1、气液混合压力为0.9 MPa、气液混合速度为6 m3/s时,系统取得了最佳灭火效能,对有限空间建筑火灾的实战处置效果明显。试验结果为一线消防救援队伍制定高效的火场处置、战斗编成等成套化灭火技战术措施提供依据,有利于推动队伍实战处置效能的有效提升。

Abstract: According to the disaster characteristics and main hazard characteristics of high-rise, underground, large-span and other confined space buildings after fire, combined with the actual needs, this paper uses the micro structure compressed air foam extinguishing system, and uses high-precision mixed compressed air foam system with particle size in the range of 100~200 μm to effectively suppress the fire in the confined space buildings, and investigates the actual impact of the gas-liquid ratio, gas-liquid mixing pressure, gas-liquid mixing speed and other related factors of the compressed air foam extinguishing system on the fire disposal process of confined space buildings. The results show that the compressed air foam has the corresponding advantages of sufficient foaming, uniform and delicate foam, good stability, high fire extinguishing efficiency, and strong anti reburning ability. When the gas-liquid ratio of the compressed air foam fire extinguishing system is 6:1, the gas-liquid mixing pressure is 0.9 MPa, and the gas-liquid mixing speed is 6 m3/s, the system achieves the best fire extinguishing efficiency, and has obvious effect on the practical disposal of building fires in confined space. The experimental results provide a basis for efficient fire scene disposal, combat organization, and other comprehensive fire extinguishing technical and tactical measures for frontline firefighting and rescue teams, which is conducive to promoting the effective improvement of the team's practical disposal efficiency.
