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。得出了在大容器中点火,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 importantly scientific and practical values to take experimental research on the process of prernixed gas explosion in linked vessels. In this paper,different fire-lit positions, initial pressure and initial density were studied in detail to obtain their impacts on gas explosion pressure in linked vessels. The result showed that if you cause fuel to burn in a big vessel, then the linked small one would have higher explosion pressure. The rate of pressure rised also rapidly. The influence of initial density on the linked vessels was basically consistent with the single one. If the initial pressure increased, explosion pressure in linked vessels increased as well, futhermore, it went up more quickly in small vessels than in the big ones. Consequently, during the industrial process, the most effective method is the partition of explosion, that is, to install a separation device around the vessel and pipe joint, in order to prevent explosion from spreading through pipes.
