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.
