摘要
对连通容器内预混气体爆炸过程进行实验研究,具有重要的科研和实用价值。本文通过实验室内自制的实验仪器详细研究了不同的点火位置、初始压力、初始浓度对连通容器内预混气体爆炸压力的影响。结果显示,在大容器中点火,会引起更大的爆炸压力;压力上升速率也增大很快。初始浓度对连通容器内预混气体爆炸的影响基本与单个容器中的影响一致。当初始压力增大时,连通容器的爆炸压力也随着一起增大,而且小容器比大容器增加更快。因而,在工业中,最有效的方法是隔爆,在容器和管道接口设置隔离装置,使爆炸不能通过管道传播。
It is of scientific and premixed gas explosion in linked initial densities were investigated results showed that if fuel was b linked smaller one. The rate of pr practical importance, to do experimental research on the vessels. In this paper, different firing positions, initial pre to obtain their impacts on gas explosion pressure in linked v urned in a big vessel, a higher explosion pressure would re process of ssures and essel sult essure rise was also rapid. The influence of initial density on the s. The in the linked vessels was basically consistent with that on a single vessel. I{ the initial pressure increased, explosion pressure in linked vessels increased as well. Furthermore, it increased more quickly in the small vessel than in the large one. Consequently, during the industrial process, the most effective method is the partition of explosion, that is, to install a separation device on the joint between the vessel and the connecting pipe to prevent explosion from spreading through pipes.
