丝网结构对连通容器气体爆炸的二次抑制效果
Double-suppression effect of wire mesh on gas explosion in linked vessels
摘要
Abstract
A series of experiments were conducted to study double-suppression effect of multi-layer wire-mesh structure on methane-air mixture explosion in a spherical vessel connected with pipelines. Explosion double-suppression effect was analyzed for explosion suppression structures with different layers and meshes. The most reasonable multi-layer wire-mesh structure was obtained. The combination of different layer number and mesh number had different explosion suppression effect on the linked vessels. Compared with single-suppression effect, the double-suppression effect was much better. Based on 5-layer 60-mesh, which had little single-suppression effect, the double-suppression effect was more effective while the 5-layer 40-mesh was adopted as double- suppression structure. 1-layer 60-mesh or 3-layer 60-mesh had little suppression effect, but 5-layer was different. When the layer of wire-mesh was more than five, the effect was significant, and the more the number of layers was, the better the explosion suppression effect was. Thus, in actual explosion protection design, the best explosion suppression structure should be decided by taking into account of the comprehensive effect of the times of suppression and layer number and mesh number of wire-mesh structure.关键词
