摘要
火场排烟是建筑火灾扑救的重要战法,能够为灭火救援创造有利条件。直流喷雾水枪排烟作为一种新兴的排烟方式,在国内外已有应用,但缺乏系统的理论研究,亟须开展相关试验进行验证支撑。本文通过设计移动式正压送风排烟机排烟、自然排烟、直流喷雾水枪正压喷雾排烟和直流喷雾水枪液压通风排烟4种试验方案,模拟其在相同条件下的排烟效果,通过量化分析可见光线穿透烟雾的衰减程度,评估各排烟方式的排烟效率。试验数据显示,利用移动式正压送风排烟机的排烟效果最好,用时最短;利用直流喷雾水枪液压通风排烟在有效排烟时间内的有效排烟量最高,效率最高;自然排烟效率最低,用时最长。
Smoke exhaust at the fire scene is an important tactic for extinguishing building fires,which can create favorable conditions for firefighting and rescue.As a new smoke exhaust method,the straight-spray water gun has been applied at home and abroad,but there is a lack of systematic theoretical research,and it is urgent to carry out relevant tests to provide validation and support.This paper simulates the smoke exhaust effect under the same conditions by designing four test schemes of mobile positive pressure air supply smoke exhaust fan,natural smoke exhaust,straight-spray water gun positive pressure spray smoke exhaust and straight-spray water gun hydraulic ventilation smoke exhaust,and evaluates the smoke exhaust efficiency of each smoke exhaust mode by quantifying the attenuation degree of visible light penetration smoke.Experimental data shows that using a mobile positive pressure air supply smoke exhaust fan has the best smoke exhaust effect and the shortest time required;The effective smoke exhaust volume and efficiency of hydraulic ventilation with straight-spray water gun is the highest within the effective smoke exhaust time;The natural smoke exhaust efficiency is the lowest and takes the longest time.
