摘要
在海洋工程建造中,设备和仪表管线的清洁度对生产平台的安全长效运行起着举足轻重的作用。串油作为高效的管线清洁方法,现有研究主要对串油工艺流程进行分析,缺少对串油效率提升及方法优化的研究。本文通过对串油设备、施工流程、串油效率的影响因素进行研究,对比串联串油和并联串油的特点,提出了一种可以多路并串的串油工装,并且基于ANSYS Fluent软件对油料在工装内的流动特性进行了数值模拟。根据模拟结果,提出了单列结构、对称结构和错位结构三种优化形式,然后对比三种优化结构相较于原工装的流量分配特性。研究结果表明,对称结构形式下油料的流量分配一致性最高,其4条支路流量基本满足43.73L/min的流量要求,可以实现多路并串。
In the offshore engineering construction,the cleanliness of equipment and instrumentation pipelines plays a vital role in the safe and long-lasting operation of production platforms.Oil flushing as an efficient pipeline cleaning method,the existing studies have focused on analyzing the oil-flushing process itself,while paying little attention to improving flushing efficiency or optimizing the methodology.In this manuscript,the oil flushing equipment,construction process,factors affecting oil flushing efficiency are studied.Then the characteristics of series and parallel flushing methods are compared.Finally,an oil flushing device that can be used in multiple parallel flushing is proposed,and numerical simulation of the oil flow characteristics in the device is carried out based on ANSYS Fluent.According to the results of the simulation,three optimized forms of single column structure,symmetric structure and staggered structure are proposed,and the flow distribution characteristics of the three optimized structures are compared with those of the original structure.The research results show that the flow distribution consistency of the oil in the form of symmetric structure is the highest,and its four branch flow basically meets the flow requirement of 43.73L/min,which can realize multiple parallel flushing.
