摘要
依据池火灾的基本理论,以天津某企业二氯丙烷存储罐区为例,利用BrLtz模型和辐射强度与伤害/破坏准则构建了单罐罐内池火的火灾风险评估模式.采用回归分析方式,拟合给出了求算"给定辐射强度"条件下,目标到池中心距离X的最优曲线方程为幂函数Y=1 657X-2.432.罐内池火灾模拟的结果表明,邻近生产装置最近的储罐发生罐内池火时,造成人员死亡和设备与建筑物完全损坏的后果,覆盖临近总厂道路和废弃建筑物两侧的过往行人与通行车辆、灌装车辆、废弃建筑物一定程度受损,生产装置不会受到损伤,生产装置内的生产人员不会受伤.
Based on the basic theory of pool fire, taking the storage tank farm of an dichloropropane enterprise in Tianjin as an example, the patterns of fire risk assessment by us- ing BrLtz model and criteria of radiation intensity and harm/damage were established. By means of regression analysis, the method of calculation for solving the distance （X） to the cen-tre of pool fire at the given radiation intensity （Y） was given, and the optimum curve equation is Y=I 657X^-2.432. The tank fire simulation results of pool fire in tank show that pool fire in tank closest approach to production device can cause casualties and destroy equipment and buildings completely. This bad influence affects the road surrounding the enterprise, the peo-ple, and filling vehicle passing by on both sides of the abandoned buildings near the factory. The abandoned buildings will be impacted in a way. The production equipment will be not damaged. The staff within the production equipment will not be injured.
