Abstract:

Water content of natural gas affects the quality and safety of pipeline transportation. As one of the main methods of gas concentration detection, non-contact laser detection has been widely used. In order to solve the problem of stray radiation on high temperature wall during laser detection, an on-line laser detection optical path for water content of natural gas pipeline was designed. The influence of stray radiation on the received signal of detector was simulated by TracePro. The optical characteristics of the process were analyzed based on the principle of spectral absorption. The results show that there is obvious stray radiation in the process of measuring water content of natural gas in pipeline by laser, and the stray radiation effect is stronger in high temperature environment.

Key words: natural gas, measurement, high temperature, radiation

摘要:

天然气含水量影响管道输送品质及输送安全,非接触激光检测作为目前气体浓度测量的主要方式之一,已被广泛应用。针对激光检测过程中存在高温壁面杂散辐射问题,设计了管输天然气含水量激光在线检测光路,利用TracePro光学仿真软件模拟管道壁面高温杂散辐射对探测器接收信号的影响,并基于光谱吸收原理分析该过程的光学特性。研究结果表明,在激光检测管输天然气含水量过程中,存在较为明显的杂散辐射,且在高温环境下,杂散辐射影响更为强烈。
