小龙钨矿是一个中型矿山,全矿有五个机修单位经常使用乙炔进行切割、焊接。建矿三十多年,乙炔发生器爆炸事故发生了十余起,冲毁过房屋,选矿车间的一次爆炸还造成一名工人当场死亡。为了杜绝乙炔发生器回火爆炸,我们进行了一些改进,改进后的乙炔发生器如图1. Little Dragon tungsten ore is a medium-sized mine, the mine has five mechanics often use acetylene cutting, welding. Thirty years after the mine was built, an explosion of acetylene generators took place more than ten times and houses were destroyed. An explosion at the beneficiation workshop also caused the death of a worker on the spot. In order to prevent the tempering explosion of the acetylene generator, we made some improvements. The improved acetylene generator is shown in Fig.1.
