摘要:
为探究含有不同添加剂细水雾熄灭醇类火焰的效果,对含不同浓度尿素、钾盐、FC-4添加剂的细水雾分别开展灭火实验。结果表明:在同等条件下,对比含不同浓度尿素细水雾的平均灭火时间,含1%尿素细水雾熄灭酒精火焰时间最短,与纯水相比灭火时间减少率达到了44.63%;含有K2C2O4•H2O细水雾熄灭酒精火和煤油火的平均灭火时间均为最小,灭火减少率分别达到了31.35%,73%;含有KHCO3细水雾熄灭酒精火和煤油火的平均灭火时间最大,灭火时间减少率分别为6.75%,57.56%。由此对比可得,含有钾盐细水雾熄灭煤油火比酒精火的效果要好。在复合添加剂中,含有0.05%的FC-4、1%的尿素和0.2mol/L K+浓度的K2C2O4·H2O的细水雾熄灭酒精火的平均灭火时间最短,灭火时间减少率也达到了87.90%,灭火效果显著。对比上述分析,含复合添加剂细水雾的酒精灭火效果更好,可以实现有效灭火。
Abstract:
In order to investigate the effect of water mist containing different additives on the alcohol extinguishing fire,exting experiments were carried out on water mist with different urea concentrations,potassium salt and FC-4 additives.The average fire extinguishing time of water mist with different concentrations of urea was compared under the same conditions.Comparing with water mist,water mist containing 1% urea extinguished the alcohol fire in the shortest time,the extinguishing time reduction rate reached 44.63%.Water mist with K2C2O4· H2O extinguishied alcohol and kerosene fire in the minimal average extinguishing time,the extinguishing time reduction rate of fire suppression were 31.35%,73% respectively.Water mist with KHCO3 extinguishied alcohol and kerosene fire in the maximal average extinguishing time,and reduction rates were 6.75%,57.56% respectively.Water mist containing potassium extinguishing kerosene fire effect was better than to alcohol fire by contrast.Of all the compound additives,Water mist containing 0.05% FC-4,1% urea and K2C2O4· H2O with 0.2 mol/L K + extinguished the alcohol fire in the shortest time.And the extinguishing time reduction rate of fire suppression was 87.90%,the effect of fire suppression was remarkable.Compared with the above analysis,water mist containing compound additives was the better in alcohol extinguishing fire effect,and can realize extinguishing fire effectively.
