摘要
利用现役的天然气管道掺氢混输，是实现氢气大规模、长距离和低成本储运的有效方法。开发高效便捷的掺氢设备，增大天然气和氢气的掺混均匀度，有利于提高氢气输送效率、保障管道长距离输送及下游用气安全。利用文丘里管作为掺氢设备，用甲烷替代天然气，将甲烷和氢气进行掺混，采用数值模拟的方法，研究了不同的掺混结构和工况对甲烷和氢气掺混流动过程及掺混均匀度的影响。结果表明，在T型管道后添加文丘里管可以增大掺混均匀度。在模拟工况下，当管喉比（文丘里管喉管段与直管段直径比）为1/3时，掺混效果最好；当掺氢比（氢气与甲烷的质量分数比）为15%时，掺混效果最好，掺混均匀度随着掺氢比的增大而增大。与静态掺混器相比，即使甲烷流速较小，添加了文丘里管的管道内仍可保持较大的掺混均匀度。运行压力越小，掺混均匀度波动越小，掺混过程更稳定。
Abstract
Utilizing the existing natural gas pipelines for hydrogen blending is an effective method for achieving large-scale
long-distance
and low-cost storage and transportation of hydrogen. Developing efficient and convenient hydrogen blending device and improving the blending uniformity of hydrogen and natural gas can improve hydrogen transportation efficiency and ensure long-distance pipeline transportation and downstream gas safety. Using a Venturi tube as the hydrogen blending device
methane was used instead of natural gas to mix methane and hydrogen. By numerical simulation method
the influence of different blending structures and operating conditions on the flow process and blending uniformity of methane and hydrogen was studied. The results show that adding a Venturi tube after T-shaped pipeline can effectively improve the blending uniformity. Under the simulated operating conditions
the best blending effect is achieved when the tube-throat ratio (diameter ratio of throat section to straight section of the Venturi tube) is 1/3. When the hydrogen blending ratio (mass fraction ratio of hydrogen to methane) is 15%
the blending effect is the best
and the blending uniformity increases with the increase of the hydrogen blending ratio. Compared with static mixing devices
even with low methane flow rates
the pipeline with added a Venturi tube can still maintain great mixing uniformity. The lower the operating pressure
the smaller the fluctuation of blending uniformity
and the more stable the blending process.
