摘要

对甲烷-空气预混气体在连通容器内的泄爆过程进行了实验研究，与密闭容器爆炸过程进行了比较，研究了连通容器泄爆过程中压力的变化规律，分析了气体浓度和泄爆方式对连通容器泄爆过程的影响。结果表明，连通容器泄爆过程中，压力最大值通常出现在管道末端，由于震荡在球形容器内产生真空压力；与略低于化学计量比浓度相比，甲烷体积浓度略高于化学计量比浓度时，连通容器内爆炸压力增加，这种情况与单个密闭容器气体爆炸相同；两个泄爆口泄爆能较好地降低连通容器内最高爆炸压力，而仅采用一个泄爆口泄爆并不能显著降低容器内的最大爆炸压力。研究结论为工程上连通容器的泄爆安全设计提供重要参考。

Abstract

The experiment about explosion venting process of methane-air mixture in linked vessels was conducted.It was compared with the single closed container explosion process.The law of pressure variation in linked vessels and the influence of gas concentration and the way of explosion venting are studied.It was concluded that the maximum explosion pressure usually appeared at the end of the pipe.Vacuum appeared because of pressure vibration in the sphere vessel.The same as single vessel

the explosion pressure was higher when the volume concentration of methane was a little more than stoichiometric ratio comparing with the lower concentration.Two vent ports decreased the maximum pressure in the linked vessels better than only one port.The conclusions provided scientific basis in engineering for safety design of gas explosion venting of linked vessels.
