本文介绍了在25米~3单砖建筑物中进行的四次液化石油气-空气混气的爆炸试验。由于建筑物内壁装了爆炸减压板,爆炸最大压力被减低到8千帕之下,建筑物主体结构完好无损。 建筑物内的很多化学操作都含有可燃液体或者可燃气体。当工艺设备出现偶然的破碎时,燃气或者可燃液体的蒸气便能够播散在建筑物内,与空气混合后形成爆炸混合物。为了防止这种可燃混气爆炸对建筑物造成严重破坏,常规方法对建筑物设置泄压面积。文 This article describes the four LPG-air blast tests carried out in a 25 m to 3 single brick building. Due to the explosive decompression board installed on the inner wall of the building, the maximum explosion pressure was reduced below 8 kPa, and the structure of the main building was intact. Many chemical operations in buildings contain flammable liquids or flammable gases. When the process equipment accidentally broken, the gas or flammable liquid vapor will be able to spread in the building, mixed with air to form an explosive mixture. In order to prevent such combustible gas explosion causing serious damage to the building, the conventional method of setting the relief area of ​​the building. Text
