可远距离检测可燃气体的TDLAS检测仪在西气东输的应用

Application of a TDLAS Detector for Detecting Flammable Gas from Long Distance in West-East Gas Pipeline

可调谐二极管激光吸收光谱(简称TDLAS)可燃气体检测仪检测精度高,可快速精确地探测几十米距离内的可燃气体泄漏,可用于架空管道、埋地管道以及天然气站场等的天然气泄漏检测。对比天然气分输站场使用的传统的可燃气体检测仪,能更好地满足西气东输管道公司"集中巡检"、"集中监视"、"区域化无人值守"等生产模式下可燃气体泄漏监测。

Based on the tunable diode laser absorption spectrometry （TDLAS） combustible gas detector, the detectionaccuracy is high, which can detect the combustible gas leakage within several tens of meters distance and can be used for overheadpipeline, buried pipeline and natural gas station Natural gas leak detection, compared to the natural gas transmission station usingthe traditional combustible gas detector, to better meet the West-East Pipeline Company ＂centralized inspection＂, ＂ centralizedsurveillance＂, ＂ regional unattended＂ and other production Mode of combustible gas leak monitoring.
