摘要
根据高危工艺热爆炸事故反应速度快、爆炸威力强、物证破坏严重的特点,提出3类适合该类事故分析鉴定的模拟验证法:数学模型验证法、实测模拟验证法及热分析仪器实验验证法。通过对3种模拟验证法的由来、定义及操作程序的研讨,同时对3种方法的用药量、结果可信度、优点及缺点进行比较,从而总结出3类方法在不同事故背景、物证收集情况及前期推断基础下的适用范围。最后,通过对一起高危工艺热爆炸事故的调查鉴定,探讨热分析仪器实验验证法在调查鉴定中的应用,并给出模拟验证方法的选用技巧及运行步骤,为事故鉴定工作提供切实可用的科学参考。
According to the features of explosive accident of high-risk process, such as rapid reaction rate, strong energy release, severe damages to the accident evidence, three kinds of simulation and verification methods, including Mathematical models method, experimental method and calorimeter simulation method, which are suitable for the explosive accident in high-risk process, are summarized. The application development, definition and procedures of these three methods are presented as well as the consuming of chemical amount, the reliability of results, and the advantages and disadvantages. Therefore, the application range of these methods under different accident background, evidence collection, and pre-accident inference are concluded. In the end, through the identification of a high-risk thermal explosive accident, the application of calorimeters are discussed, so as to offer an practical case for the choosing skills of methods and detail steps, and to support the accident identification with scientific reference.
