狭长通道内细水雾型水幕阻烟性能实验研究OA北大核心CSCDCSTPCD
Experimental research on properties of smoke blocked by water mist screen in a long narrow channel
针对阻止狭长通道内火灾烟气水平蔓延的问题,本文提出利用细水雾型水幕防烟分隔方法,搭建实验台研究细水雾型水幕在狭长通道中阻烟的效果.通过分析烟气蔓延过程,测量温度分布,O2、CO2和CO浓度变化以及通道内照度变化,讨论狭长通道内细水雾型水幕阻烟的有效性.实验结果表明:细水雾开启后,其下游空间环境得到改善,可以满足安全疏散的环境要求,狭长空间内细水雾型水幕的阻烟性能良好.实验为狭长通道(隧道、长走廊)的防排烟设计提供了思路,对火场救援和人群疏散具有重要意义.
A new smoke control strategy using a water mist screen was developed to block horizontal smoke move -ment in a long narrow channel .Experiments were conducted to investigate the properties of smoke blockage realized by the water mist screen , and certain parameters were analyzed to confirm its effectiveness in blocking fire-induced smoke, such as the smoke movement process , distribution of temperature, concentrations of O2, CO2, and CO, and changes in visib…查看全部>>
