| 摘 要： | 低浓度瓦斯由于具有爆炸性,在抽采、输送、利用过程中存在较大的安全隐患,通过研究,在输送管道上安装的自动阻爆装置、水封阻火泄爆装置以及抑爆装置等三种不同原理的保护措施,可以使爆炸得到有效抑制,将管爆炸控制在一定范围内,彻底消除瓦斯在抽采、输送、利用过程中安全隐患。

| Abstract: | Because of the explosive of low concentration gas,it poses some serious safety hazards in extraction,transport and use process.Through research,the explosion can be suppressed by the installation of automatic preventing explosion devices,water sealing of fire barriering & explosion venting devices and explosion suppression devices etc protective measures in transportation pipe.The principle of these devices are different.They can control pipe explosion within a certain range,and thoroughly eliminate gas extraction,transport and use process safety hazards. |
