摘要
为探究在特定工况下湿毛巾和过滤式消防自救呼吸器的防护性能,搭建滤毒工具防护性能测试平台,针对火灾场景中的常见燃烧物,选择硬质聚氨酯、软质聚氨酯、纸张、木材、棉布、PVC、锂电池7种材料,分别测试其燃烧产物中的主要气体成分,分析普通毛巾对气体、烟尘和高温的防护性能.在特定工况下的试验结果表明:湿毛巾对7种燃烧物产生的PM10颗粒具有一定的过滤效果,平均过滤效率为25.57%;对高温烟气具有降温作用,平均降幅为 29.1℃;对HCN和CO未见明显过滤效果,对C2H4O的平均过滤效率约为28%,对SO2的平均过滤效率约为 75%,对HCl的平均过滤效率约为 84%;对比测试过滤式消防自救呼吸器对CO和烟尘的防护能力,其性能远高于湿毛巾,并具有更低的呼吸阻力.
Abstract
In order to explore the protective performance of wet towels and filtering self-saving respirator under specific working conditions,a testing platform for the protective performance of fil-ter tools was built.Seven materials,including hard polyurethane,soft polyurethane,paper,wood,cotton,PVC,and lithium bat-teries,were selected to test the main gas components in the com-bustion products,and the protective performance of ordinary tow-els against gas,smoke,and temperature was analyzed.The ex-perimental results under specific operating conditions indicate that wet towels have a certain filtering effect on PM10 produced by 7 types of combustion materials,with an average filtering efficiency of 25.57%;It has a cooling effect on high-temperature flue gas,with an average decrease of 29.1℃;No significant filtration effect was observed for HCN and CO,with an average filtration effi-ciency of about 28%for C2H4O,75%for SO2,and 84%for HCl;Considering the protective ability of the filtering self-saving respirator against CO and smoke,its performance is much better than wet towel,and has lower respiratory resistance.
