Research on Explosion Overpressure Assessment of Vertical Doom Roof Tank
摘要
Abstract
In order to predict the external overpressure strength of vertical doom-roof oil tank during explosion and provide reference for safety regulation in tank farm, the external field overpressure produced by the 3000 m 3 vertical doom roof oil tank internal explosion is estimated by simulation scale method and TNO multi-energy method. And aimed at the subjectivity and the blindness of selecting the initial explosion intensity of multi-energy method, a new idea is brought up which is based on experiment to decide the initial explosion intensity. At the same time, the experimental value can be converted to the 3000 m 3 vertical doom roof oil tank external field overpressure value at corresponding positions by TNO multi-energy method's scaled distance equation, which is similar to the results of TNO multi-energy method. It is indicated that the prediction by TNO multi-energy method is accurate, while the simulation scale method is only suitable to estimate the overpressure field closed to the tank. When the oil storage condition is half of the 3000 m3 vertical doom roof tank, the initial explosion intensity to TNO multi-energy method is level 5. Through assessment on explosion overpressure of vertical doom tank, it provides reference for the preparation of emergency plan and safety spacing design at oil tank farm.关键词
