摘要
在天然气泄漏检测中,地下沼气对天然气管道泄漏检测具有干扰性,可能造成误判,导致无效开挖,浪费人力物力。为此,采用基于色谱分离原理和半导体传感器检测相结合的技术,开发出一种新型乙烷辨识仪,可有效区分是天然气泄漏还是沼气干扰。该辨识仪对乙烷气体识别的最低检测限为10μL/L,具有测量精度高、稳定可靠等优点,可大规模推广到天然气管道泄漏检测的应用中。
In the detection of natural gas leakage,marsh gas has interference to the detection of natural gas pipeline leakage,which may cause misjudgment and lead to ineffective excavation and waste human and material resources.For this reason,a new type of ethane identification instrument is developed based on the combination of chromatographic separation principle and semiconductor sensor detection technology,which can effectively distinguish between natural gas leakage or marsh gas interference.The minimum detection limit of the identification instrument for ethane gas is 10μL/L,which has the advantages of high accuracy,stability and reliability,and it can be widely applied to the leakage detection of natural gas pipelines.
