摘要


燃气泄漏可能引发重大安全事故和环境污染,因此发展有效的检测技术是确保安全和环保的关键。本文研
发了一种集成的场站固定式高精度燃气泄漏监测系统,该系统由廓线分析系统和天然气泄漏检测系统组成。廓线分
析系统具有 5个进气通道,内置阀控软件自动切换进气口,保证多个监测点的空气循环流通,并对各监测点空气进
行周期性采样,输送给天然气泄漏检测系统。天然气泄漏检测系统由甲烷气体分析仪、风向风速仪及报警系统组成。
甲烷气体分析仪接收来自廓线分析系统的气体样本,实时测量和显示甲烷浓度;风向风速仪实时测量风速和风向;报
警系统整合并处理来自甲烷气体分析仪和风向风速仪的数据,反演泄漏流量,设定甲烷浓度阈值并在超过时发出警报。
