摘要
随着原油储备库规模的大型化、集约化,原油储罐也逐渐向大罐容方向发展,罐区一旦发生火灾,极易引发连锁火灾效应,造成巨大的经济损失甚至人员伤亡。为合理设计大型原油储罐的安全间距,降低着火罐对邻近罐的热辐射,采用CFD技术对储罐火灾进行数值模拟,通过控制单一变量和设计正交试验工况,分析了风速、喷淋强度、油品燃烧速率3个因素对大型原油储罐安全间距的影响。结果表明:3个因素按照影响程度从高到低排序依次为喷淋强度、风速、油品燃烧速率;若要减小储罐安全间距,建议通过加大冷却水喷淋强度来调节。研究结果可为原油储备库的布局设计提供指导。(图8,表5,参24)
With the large-scaling and intensification of crude oil reserves,storage tanks are also developed in the direction of large capacity.Hence,it is easy to trigger a chain fire effect in the tank farm once a fire occurs,causing huge economic losses and even casualties.In order to reasonably design the safety distance of large crude oil storage tanks and reduce the heat radiation effect of the firing tank on the adjacent tanks,the fire of the storage tank was numerically simulated with the CFD technology.Meanwhile,the influence of the three factors,including the wind speed,spray intensity and oil burning rate,on the safety distance of large crude oil storage tanks were analyzed by controlling a single variable and designing the orthogonal working conditions.The results show that the three factors ranking in a decreasing order of influence are the spray intensity,wind speed and oil burning rate successively.To reduce the safety distance between the storage tanks,it is recommended to increase the spray intensity of cooling water.Thereby,the research results could provide guidance for the layout design of crude oil reserves.(8 Figures,5 Tables,24 References)
