摘要:
为解决工程实践中对于氢气管道的投产混气规律认识不明而带来的投产安全性问题，对大口径长输氢气管道投产中的气体置换规律开展先导性研究，建立氢气管道投产模型并验证模型的可靠性，探究置换速度和管道倾角对混气发展的影响规律。研究结果表明：根据混气特征和增长速率，混气过程可分为3个阶段；氢气管道的投产置换速度须明显高于天然气投产相关规范中规定的置换速度以确保混气安全性；水平管道相较于倾斜管道混气段更长，氮气用量更大，因此在实际工程中由水平管道所预测的混气量是最安全的。研究结果可为长输氢气管道投产的安全操作提供一定的理论建议，为氢气管道安全建设的相关标准体系提供参考。
Abstract:
In order to solve the problem of commissioning safety caused by unclear understanding of the commissioning gas mixing law of hydrogen pipeline in engineering practice,a pilot study on gas replacement law in the commissioning process of large-diameter long-distance hydrogen pipeline was made.A commissioning model of hydrogen pipeline was established,and its reliability was verified.The influence of replacement speed and pipe inclination on the development of gas mixing was discussed.The results show that the gas mixing process can be divided into three stages according to the gas mixing characteristics and growth rate.The commissioning replacement speed of hydrogen pipeline should be significantly higher than that specified in the relevant specifications of natural gas commissioning to ensure the safety of gas mixing.Compared with the inclined pipeline,the horizontal pipeline has a longer gas mixing section and a larger amount of nitrogen dosage,therefore,the gas mixing volume predicted by the horizontal pipeline in the actual project is the safest.The research results can provide theoretical suggestions for safe operation of commissioning in long-distance hydrogen pipeline and provide reference for relevant standard system on the safe construction of hydrogen pipelines.
