摘要: 为了保障瓦斯输送管道的安全性，采用主动抑爆技术研制了ZYBG型矿用瓦斯输送管道自动抑爆装置。该装置利用火焰探测器探测瓦斯爆炸信号，并将信号通过光电转换传输给控制器，控制器对信号进行判定和分析，在爆炸接近防护区间的瞬间快速打开高压抑爆器，释放抑爆介质，熄灭火焰，阻断爆炸的进一步传播。抑爆性能试验结果表明，该抑爆装置能够在5 ms内快速捕捉火焰信息，并在35 ms内迅速喷洒抑爆介质。Abstract: ZYBG type automatic explosion suppression device of mine-used gas transmission pipeline was developed by use of active explosion suppression technology in order to guarantee safety of the gas transmission pipeline. The device adopts flame sensor to detect gas explosion signal, transmits the signal to controller through photoelectric conversion, and controller makes determination and analysis for the signal. In the moment of explosion closes to the protection range, the controller opens high pressure explosion suppressor quickly and release explosion suppression medium to extinguish the flame, so as to prevent further spread of the explosion. The test results of explosion suppression performance show that the explosion suppression device can capture flame information within 5 ms, and sprinkle explosion suppression medium within 35 ms.
