摘要
采用文献调研的方法,综述了粮食粉尘燃爆关键参数的分析方法,阐释了其氧化阶段及微观机理,讨论了冲击波传播规律,从泄爆、隔爆、抑爆技术三个方面,分析了粮食粉尘爆炸灾害抑制技术的相关机理,最后就粮食粉尘爆炸防控措施方面存在的问题提出几点建议。
By means of literature review,the analysis methods of key parameters of grain dust combustion and explosion are summarized.The oxidation stage and its micro mechanism were explained.The propagation law of shock wave is discussed.The mechanism of grain dust explosion suppression technology was analyzed from three aspects of explosion relief,explosion-proof and explosion suppression technology.Finally,several suggestions are put forward on the problems existing in grain dust explosion prevention and control measures.
