摘要
冲蚀磨损是导致高炉煤气管道损坏的重要原因,在工业应用中,通常使用盲三通来减轻冲蚀磨损的程度.为了研究高炉煤气管网中盲三通的冲蚀现象,运用ANSYS仿真软件建立管道仿真模型,分析了颗粒粒径、管径和入口流速对盲三通冲蚀磨损的影响.以最大冲蚀率为指标评估盲三通的冲蚀磨损程度,并分析讨论了不同因素对盲三通冲蚀磨损的影响.结果表明:在相同入口流速条件下,较大管径的盲三通最大冲蚀率最低;随着颗粒粒径增大,最大冲蚀速率显著降低,进气口与出气口的交汇区域的冲蚀磨损程度最为严重;在相同工况条件下,管径增大可以有效降低盲三通的冲蚀磨损程度.
Abstract
Erosion and wear are important causes of damage to blast furnace gas pipelines.In industrial applications,blind tees are commonly used to reduce the degree of erosion and wear.In order to study the erosion phenomenon of blind tees in blast furnace gas pipeline network,a pipeline simulation model was established using ANSYS simulation software,and the influence of particle size,pipe diameter,and inlet flow velocity on the erosion wear of blind tees was analyzed.The degree of erosion and wear of blind tees was evaluated using the maximum erosion rate as an indicator,and the influence of different factors on the erosion and wear of blind tees was analyzed and discussed.The results showed that under the same inlet flow rate conditions,the maximum erosion rate of blind tees with larger pipe diameters was the lowest.As the particle size increases,the maximum erosion rate significantly decreased,and the erosion wear at the intersection of the inlet and outlet was the most severe.Under the same working conditions,increasing the diameter of the pipe could effectively reduce the degree of erosion and wear of blind tees.
