Study on online detection method of particulate matter in natural gas pipeline based on microwave technology

摘要:Aiming at the problem of difficult detection of particulate matter in natural gas pipeline, an online detection method for particulate matter in natural gas pipeline based on microwave technology was proposed. Firstly, the characteristics of particles in natural gas pipe network were analyzed, and based on the principle of microwave measurement, microwave transmission in the pipeline was realized by means of a sealed probe. Secondly, finite element simulation software was used to study the structure optimization of the sealing probe and pipe size (distance between two probes), and the current distribution and optimal structural parameters of the microwave measurement system were analyzed. Finally, an experimental platform was built to quantitatively analyze the influence law of the output voltage of the measuring system and the concentration of particulate matter under different working conditions. The results show that when the droplet concentration in the pipeline changes from 39 mg/m3 to 210 mg/m3, the relationship between the output voltage of the measurement system and the droplet concentration is fitted by quadratic function, and the coefficient of determination R2 is above 0.966. The average relative indication error of each signal sampling point fluctuates around 5.20%, and the repeatability of the measurement system varies within 0.24%. The research results have guiding significance for the realization of the long-term detection method of subsequent natural gas pipelines, and then ensuring the safe operation of the pipeline network. ? 2023 Chemical Industry Press.
