电缆隧道火灾有效灭火技术试验研究

针对工业企业的电缆隧道的灭火技术进行试验研究,探讨电缆隧道火灾的有效灭火安全措施并对不同灭火措施的灭火效果进行分析。利用火灾动力学模拟程序软件对电缆隧道火灾进行模拟,研究火灾中喷淋系统启用前后各时间点测点温度以及各时段内的降温速率,并与试验结果作对比分析,论证了灭火实验结果有效性,确定了电缆隧道火灾中无机隔板和防火门的安全防火时效,以及4种常用灭火剂在各时段的灭火效果。

Experimental Study on Effective Fire-extinguishing Technology for Cable Tunnel Fire

Experiments on different fire-extinguishing technology for enterprise's cable tunnel were conducted so as to discover effective fire-extinguishing measures and analyze their effect.Meanwhile,a simulation of cable tunnel fire was also made so as to analyze the temperature of the test points in the tunnel and the decreasing rate of temperature in every period of time after the spray system starting.Then,a contrast was made between the experimental results and the simulating results,by which,not only was the experimental result demonstrated to be effective,but also the safety fire-prevention aging of inorganic clapboard and fire doors was confirmed as well as the extinguishing effect of four kinds of commonly used fire extinguishing agent on each period of time.
