摘　　要：为研究气态抑爆介质对洞库管路系统油气爆炸的抑制作用,研制了主动式油气爆炸抑制实验装置,搭建了洞库管路系统油气爆炸抑制实验系统。以CO2为抑爆介质,进行了油气爆炸抑制实验,与无抑爆介质条件进行了对比,并分析了火焰强度、爆炸超压值、火焰传播速度和爆炸产物等特性参数变化情况。结果表明:抑爆器通过喷射CO2,对爆炸火焰强度、持续时间有明显的抑制作用;在CO2作用下,最大爆炸超压值和最大火焰传播速度分别下降了34.21%和54.48%;通过分析油气爆炸燃烧产物,可知在CO2作用下,有较多油气并没有参与燃烧反应或者反应不完全。In order to study the effect of gaseous explosion suppressant on gasoline-air mixture explosion of pipeline system incave depot, the active gasoline-air mixture explosion suppression experimental equipment was developed and the experimental sys-tem of cave depot pipeline system gasoline-air mixture explosion suppression was set up. The gasoline-air mixture explosion suppres-sion experiment used carbon dioxide as explosion suppressant was executed. By contrast to the gasoline-air mixture explosion experi-ment with non- explosion suppressant, the change results of characteristic parameters of overpressure, flame propagation velocity,flame intensity and explosive products were studied. Experimental results indicate that with carbon dioxide which is sprayed by ex-plosion suppression equipment, flame intensity and time of duration are suppressed obviously; with the suppression effect of carbondioxide, maximum overpressure and maximum peak flame propagation velocity are reduced by 34.21% and 54.48%, respectively;by means of analyzing explosive products, it＇s known that there is lots of oil gas without participating the reaction of combustion ordoing that incompletely.
