摘要
利用自行设计的断面为30 cm×30 cm瓦斯爆炸实验管道,对不同参数的金属丝网、泡沫陶瓷材料及二者组合体的抑爆效果分别进行了实验研究。结合材料特点,分析了组合体抑爆的作用机理。结果表明:一定参数的金属丝网和泡沫陶瓷组合体,衰减爆炸超压和火焰温度效果优于各自单体,抑爆材料的损坏程度明显降低。组合体可以达到取长补短,发挥单体材料优势,回避劣势,增强抑爆效果,降低抑爆材料损坏程度的目的。
By using self-designed gas explosion experimental pipe with the section of 50 cm×50 cm, the authors carried out the experimental studies for the explosion suppression effects according to different parameters of metal wire mesh and foam ceramic materials and their combination. With the materials＇ characteristics, the function mechanism for the explosion suppression of the combination was analyzed. The results show that the performance of some parameters com- bined materials of wire mesh and the foam ceramic is better than that separate ones in the respect of pressure reduction and flame temperature and the damage of the explosion suppression materials is reduced obviously. The combined ma- terial can exert the advantages of original ones and avoid their disadvantages. The combined material can enhance the explosion suppression effects and reduce the damage of the materials.
