|
摘要
温降是热油管道修复过程中的重要参数之一,合理地确定温降对管道开挖修复方案及油品输送起到重要作用。从热力学角度,建立开挖运行后非稳态的热力学模型,并以铁锦线松山到锦州热油管道为实例进行了模拟计算。研究了开挖起点、开挖长度以及油品出站温度对热油管道内油品温度的影响,并结合CFD对不同季节开挖运行时热油管道及其周围土壤温度场变化情况进行数值模拟分析。研究成果可在保证管道安全运行的前提下,提供热油管道开挖修复建议,指导管理部门优化施工修复计划。
The calculation of temperature drop was one of the most important parameters in the repair process of hot oil pipeline,and the value played an important role in the pipeline excavation repair plan and oil transportation.The thermodynamic model of unsteady state after excavation was established from the view of thermodynamics,and the simulation was carried out on the basis of a case study of the hot oil pipeline from Songshan to Jinzhou.The influence of the different starting points,excavation length and oil station temperature on the oil temperature of hot oil pipeline was studied combined with CFD in different seasons of excavation operation of hot oil pipeline and the soil temperature field around the changes of numerical simulation analysis.The results of the study could ensure the safe operation of the pipeline under the premise of providing hot oil pipeline excavation repair recommendations and guide the management department to optimize the construction repair plan.
