以往,常听说矿井或农业产品贮藏室粉尘会发生爆炸;而近来,在塑料、金属、甚至食品工业的仓库中由于粉尘引起爆炸之事也不乏所闻。因而,认真研究一下可燃性粉尘的爆炸特性以及防止粉尘爆炸的安全技术就十分重要了。一个世纪以来,许多学者对此进行了研究,但由于粉尘爆炸的现象十分复杂,因 In the past, it was often heard that dust from mines or agricultural product storage rooms exploded; and recently, there has been no shortage of dust or dust explosions in warehouses of plastics, metals and even the food industry. Therefore, it is very important to carefully study the explosion characteristics of combustible dust and the safety technology to prevent dust explosion. For a century, many scholars have studied this, but due to the very complex phenomenon of dust explosion,
