摘要

摘要: 从工业安全角度出发，在5 L密闭容器中进行了环境湿度（40%和88%）对环氧丙烷蒸气爆炸特性参数影响的实验研究。研究结果表明，在环氧丙烷最佳蒸气浓度附近，湿度使最大爆炸压力明显下降，在爆炸极限浓度附近影响不明显；湿度对7.0%最佳体积浓度环氧丙烷蒸气的最大压力上升速率影响最为明显，其它浓度影响不明显；环氧丙烷蒸气最大爆炸温度和最大爆炸温度上升速率受环境湿度影响相对较小。

Abstract: To evaluate the hazard of gaseous epoxypropane-air explosions, characteristic parameters of gaseous epoxypropane explosion inside 5 L-sphere closed vessel with 40% and 88% relative humidity were measured. The obtained results show that: Maximum overpressures reduce slightly at near optimum explosion concentration, the others make no difference; a major influence of the initial humidity on maximum rates of pressure rise is observed only at 7.0% in the examined ranges of the gaseous epoxypropane concentrations; and the maximum temperature and the maximum rates of temperature rise are slightly influenced by the initial humidity.
