分析埋地油罐可能发生的火灾爆炸事故,建立事故模拟模型,模拟爆炸物质完全燃烧的质量依据化学计量浓度确定,事故伤害范围的计算用G.M莱克霍夫在砂质土壤中爆炸的冲击波计算方法。对50 m3埋地油罐模拟,油蒸气形成爆炸性混合气体爆炸伤害范围较大,安全范围与《汽车加油加气站设计与施工规范》中相关规定相符合。模拟方法用于埋地储罐的定量安全评价,为罐区选址、建设、安全距离确定及安全预案制定提供参考。
Analysis of possible fire and explosion accidents in buried tanks, establishment of accident simulation model, simulation of the quality of complete combustion of explosive substances, determination of stoichiometric concentration, and calculation of accident injury range Blast wave calculation method of blast explosion in sandy soil with GM Lakekhoff . For the 50 m3 buried tank simulation, the range of damage caused by the explosion of the mixed gas of oil vapor is larger, and the safety range is in accordance with the relevant provisions of “Code for Design and Construction of Vehicle Refueling and Gaging Stations”. The simulation method is used to quantitatively evaluate the safety of buried storage tanks, and provides reference for tank site selection, construction, safety distance determination and safety plan formulation.
