本质安全型甲烷在线检测系统的研制

Devolopment of an intrinsically safe on-line methane detection system

针对煤矿输气管道甲烷检测的要求及环境条件的特殊性,设计了一种本质安全型甲烷在线检测系统,成功实现了煤矿输气管道甲烷长期稳定的闭环检测。介绍了样气处理系统的组成和实施方案,以及红外甲烷传感器的特点。

An intrinsically safe on-line methane detection system was designed for closed-cycle monitoring of the gas transfer tube of coal mine. The composition and the realization procedure of the sample handing system, and the characteristics of the infrared methane sensor are described.
