静电放电引起豆粕残留气体爆炸事故分析

Analysis of gas residue from soybeanexplosion accident inducedby electrostatic discharge

易燃或可燃液体蒸发而形成的挥发性气体与空气均质混合后引发的爆炸属于气体爆炸。气体爆炸现场与炸药爆炸现场相比具有不同的特点。本案例根据现场勘查情况,运用静电放电理论确定了气体爆炸的点火源,澄清了爆炸事故的性质。

Explosion caused by volatile gas and air mixture that is evaporated by flammable or combustible liquid belongs to gas explosion. Compared with common explosive scene, gas explo- sive scene has different features. According to the scene investigation, this case identifies gas explosion ignition source, clarities the explosion properties using electrostatic discharge theory.
