柱形容器开口泄爆过程中压力发展特性的实验研究

Experimental Investigations of Pressure Development During Explosion Vent from Cylindrical Vessels

在体积为 0 0 2 5m3 的柱形容器中 ,采用底端中心点火方式 ,对 4 1%的丙烷 空气、9 5 %甲烷 空气预混气的顶端开口泄爆过程进行了实验研究。实验结果给出了不同泄爆面积和不同泄爆压力条件下容器的内压力发展历史。就不同泄爆条件对容器内爆炸发展产生的影响进行了讨论。

Experimental investigations were done during explosion vent in a 0.025m 3 vertical cylindrical vessel. 4.1% Propane and 9.5%methane air mixtures were used with central bottom spark ignition.When vent occured at diferent failure pressure through different vent area,pressure histories were obtained at the vessel wall.Possible mechanisms for vent explosions are discussed.
