摘要(Abstract):

试验表明,在可燃气云爆炸引发过程或爆炸初始阶段,通过喷洒抑爆材料可抑制爆炸燃烧反应进程,继而中断爆炸反应或显著削弱爆炸强度。无机粉末、惰气和水雾是性价比较高的抑爆材料,具有大面积推广的价值。探讨了可燃气云的抑爆机理,并指出可燃气云抑爆技术后续研究中亟待解决的问题,为可燃气云抑爆技术的实际应用提供了技术参考。
Tests indicate that the combustion reaction process of explosion can be refrained by spraying explosion suppression materials in the process of explosion triggered or initial explosion phrase of flammable gas cloud,then explosion reaction can be interrupted or explosion intensity will be weakened strongly.Inorganic powders,inactive gas,and water mist are excellent materials on explosion suppression,which are worthy of being used widely.The mechanisms on explosion suppression of flammable gas cloud were discussed,and the most important problems for subsequent study were pointed out,which provide the reference for the application of explosion suppression technology.
