Five kinds of density methane was selected and tested in the horizontal pipeline gas exploding device to research the change rule of the maximum explosion pressure,the maximum rate of pressure rise and the arrival peak time with the methane concentration and propagation distance.
在水平管道式气体爆炸装置中,选取5种不同浓度的甲烷进行爆炸实验,研究在甲烷爆炸传播过程中,最大爆炸压力、压力上升速率及压力峰值时间随甲烷浓度及传播距离的变化规律。
In the contrast,the maximum rate of pressure rise decreases with relieving pressure increasing.
实验发现,最大泄爆超压随着泄爆膜动作压力的增大而上升,而最大升压速率的变化规律则与之相反;泄爆导管越粗,容器内的最大泄爆超压越低;相比无泄爆导管的情况,安装泄爆导管后的最大泄爆超压和最大升压速率会在更高的浓度下达到最大值;最大升压速率随粒度的减小而增大;同条件下安装泄爆导管后的超压值要大于未装泄爆导管时的值。
The results show that both the explosion pressure and the rising rate of explosion pressure increase with the decreasing of the size of aluminum particles.
结果表明,爆炸压力及爆炸压力上升速率都随着铝粉粒度的减小而增大,粒度为6～8μm,9～12μm,15～17μm铝粉的平均最大爆炸压力分别为0。
