油气储罐火灾爆炸风险模拟评估方法研究及软件系统开发

油气储罐由于固有的火灾和爆炸危险性,一旦发生泄漏会导致火灾和爆炸事故的发生,因此研究油气储罐的风险评估方法对于预防和控制事故的发生具有十分重要的意义.随着计算机技术的发展,运用计算机模拟技术模拟危险化学品储罐事故后果,以及对环境的危害过程成为可能.针对油气储罐的火灾爆炸特性,在对现有各种火灾爆炸损伤模型总结分析的基础上,对几种常见事故选择和确定了其模拟数学模型,并开发了火灾爆炸事故评估的软件系统,详细介绍软件系统的功能和组成框架.软件系统由储罐危险源识别系统、火灾爆炸分析评估系统、油气储罐事故预防和控制训练系统和数据库系统组成.该系统可以对事故后果包括危险区域、人员伤害范围、经济损失等进行量化计算和分级,通过对模拟结果的分析与比较可以得剑火灾爆炸事故的等级,软件系统可以完成风险评估,从而大大提高了评估的效率和科学性.

The research and software development on simulation assessment method for oil gas storage tank's fire & explosion

On account of the hazard of huge fire & explosion oil gas storage tank occurred,so leaked out or fired.and lead to fire explosion accident easily.Therefore,to study the important of the hazards is a key of preventing and controlling the accident efficiently.With the popularization & application of computer technology,it is feasible to simulate the process of hazardous chemical tanks and impact on environment.Aiming at the characteristics of fire & explosion of oil gas storage tank,the mathernatical stimulation model corresponding to each accident damage model is selected on the basis of analyzing and summarizing lots of danger models of fire and explosion occurred.A software simulation evaluation on fire & explosion of oil & gas storage tank is experimental developed.The functions,framework and development of the system are introduced.The software can iudge ifa serials oftanks are major hazards.The software system is made up of storage tank significant dangerous source identification system,fire blast analogue & evaluation system,oil & gas storage tank fire prevention learning system and backstage database system.With the use of system,accident results including hazardous area,human injured and economical losses are quantitatively calculated and quantiflcationally divided into grades Some rules in fire and explosion accidents can be got by comparing and analyzing during simulation results groups.It makes the risk assessment work run in a computer software way.As a result,the accuracy and efficiency assessment work are enhanced and the evaluation results become more objective and scientific.
