应用Fluent模拟防爆格栅火焰淬熄情况,并对结构参数和火焰淬熄之间的关系进行定性分析。结果表明,扩张腔直径和平板厚度对火焰淬熄效果有一定的影响,扩张腔角度和长度变化对火焰淬熄效果基本无影响,为防爆格栅的设计及应用提供参考。 Fluent was used to simulate flame quenching of explosion-proof grille, and the relationship between structure parameters and flame quenching was qualitatively analyzed. The results show that the diameter of the expansion chamber and the thickness of the flat plate have a certain effect on the flame quenching effect. The change of the angle and the length of the expansion chamber has no effect on the flame quenching effect, providing a reference for the design and application of the explosion grille.
