摘要
针对ATP缓冲仓工艺油母页岩粉尘爆炸危险性问题,根据油母页岩粉尘爆炸机理和粉尘爆炸的危险因素构建了ATP缓冲仓油母页岩粉尘爆炸的事故树,在事故树分析的基础上建立了评价指标体系,并运用突变级数法对油母页岩粉尘防爆安全进行评价。结果表明ATP缓冲仓油母页岩粉尘爆炸危险性评价数值为0.63,爆炸危险性等级为2级属于较安全的范畴,此方法为粉尘防爆安全评价提供了新的思路。
Normally there is an explosion risk for oil shale dust.In this study,an event tree associated with the oil shale dust explosion in ATP surge bin was constructed based on the explosion mechanism of oil shale dust and the hazard factors associated with oil shale explosion.In addition,an index evaluation system was established on the basis of the event tree analysis.Also,the probability of oil shale dust explosion was evaluated using a catastrophe progression method.The result shows that the probability of oil shale dust explosion risk in ATP surge bin is 0.63,and the explosion hazard rank is Level 2 which falls into a relative safe category.The method developed in this study provides a new insight for the safety analysis on oil shale dust explosion.
