摘要:: 射流清管器在管道吹扫作业中被广泛使用，但仍存在射流强度不高、吹扫覆盖面不全等局限。为了清除大口径天然气管道中饱和气析出的游离水及少量粉尘、锈渣等杂质，研究并设计了一种具备主动旋转结构的新型射流清管器，分别配置4、6、8个支状喷嘴，通过从径向、轴向剖面和距轴心不同位置三个维度分析流场射流流速和湍流动能变化规律，结果表明：沿清管器运动方向，随着支状喷嘴数目增加，流速增大，湍流动能减小。综合对比分析后得出，配置6个支状喷嘴时，管道内旋流射流叠加效果最佳，速度衰减较缓慢，稳定时间最长，且湍流动能大小适中，具有最优吹扫分布，可完成对大口径天然气管道内壁的均匀清理作业。新型旋转射流清管器在工程实践中得到了推广应用，显著提高了管道吹扫作业效率。

Though widely applied in pipe blowing, the jet pipe cleaner is subject to weak jet intensity and incomplete blowing coverage. To remove the free water precipitated from saturated gas and a small amount of dust, embroidery slag and other impurities in largediameter natural gas pipelines. A new jet pipe cleaner with active rotation structure was designed with 4, 6, and 8 branched nozzles, respectively. From perspectives of the radial, axial profile, and different positions from the center of the axis, the flow field jet flow velocity and turbulence kinetic energy changes were analyzed. It is found that in the direction of pipe cleaner movement, the number of branched nozzles increases with the greater flow velocity and the smaller turbulence kinetic energy. According to the comprehensive analysis, with 6 branched nozzles, the superposition effect of the rotary jet is optimal in the pipeline, with the slow decay of velocity, the longest stabilization time, the moderate size of the turbulent kinetic energy, and the optimal blowing distribution. The uniform cleaning operation of the inner wall of the large-diameter natural gas pipeline can be realized. The new jet pipe cleaner is applied in engineering practice and greatly improves the efficiency of pipe blowing.
