【摘要】：数据可视化技术的发展为核电站的蒸汽发生器维护与检修提供了一种新的思路。在蒸汽发生器维护与检修过程中,可视化显示传热管泥渣测量数据,不仅有效地为蒸汽发生器维护与检修过程提供详实的泥渣分布位置,而且有助于技术人员进行传热管涡流检查,从而对蒸汽发生器传热管泥渣总量评估、泥渣冲洗及指导蒸汽发生器维修等活动提供参考依据。目前,现有的蒸汽发生器传热管检修和泥渣清洗方法是使用专业的清洗工具逐个清洗整根传热管。但是由于蒸汽发生器是由成千上万根传热管按照一定的分布组成的,且每根传热管长度较长,所以这种逐根全管清洗方法就显得非常繁琐和笨拙,并且需要消耗大量的维护检修时间,不利于生产。此外,传热管管径一般较细并且每根都有弯曲,检修人员在使用清洗工具维护时,容易损坏传热管,不利于提高生产效率。为了提高传热管检修和泥渣清洗的效率,本文提出了一种基于结垢数据可视化显示系统的传热管泥渣检测和清洗方法。为了构建可视化显示系统,对泥渣数据的管理和可视化显示方法进行了研究,并在对蒸汽发生器传热管检修和泥渣清洗需求功能分析的基础上,设计了蒸汽发生器传热管泥渣数据管理结构和泥渣可视化显示功能模块;并对经典三维体数据可视化显示算法Marching Cube进行研究,在此基础上实现了整体传热管泥渣分布的可视化渲染图形的快速生成。基于以上研究,本文提出了常用的蒸汽发生器传热管泥渣的可视化显示算法,并在Hoops二次开发的基础上,构建了蒸汽发生器泥渣数据可视化显示系统。通过导入实测的传热管泥渣检测数据,对蒸汽发生器传热管泥渣可视化显示进行了验证。结果表明,本文提出的基于可视化的蒸汽发生器传热管泥渣维护与检修方法,可以为蒸汽发生器的泥渣清理工作服务,方便指导蒸汽发生器的维护工作,提高了维护效率,降低了维护成本。
[Abstract]:The development of data visualization technology provides a new idea for the maintenance and repair of steam generators in nuclear power plants. In the process of steam generator maintenance and repair, the measurement data of heat transfer pipe sludge can be visualized, which not only provides a detailed distribution position of mud slag for steam generator maintenance and repair process, but also can be used in the maintenance and repair of steam generator. Moreover, it is helpful for technicians to check the eddy current of heat transfer tubes, thus providing reference basis for the assessment of the total amount of sludge in steam generator tubes, the washing of sludge and the guidance for maintenance of steam generators. At present, the existing steam generator tube maintenance and sludge cleaning method is to use professional cleaning tools to clean the whole tube one by one. But because the steam generator is made up of thousands of heat transfer tubes according to certain distribution, and each heat transfer tube is longer in length, the whole pipe cleaning method is very cumbersome and clumsy. And the need to consume a large number of maintenance and repair time, is not conducive to production. In addition, the diameter of the heat transfer pipe is generally thin and each tube is bent, the maintenance workers use cleaning tools, easy to damage the heat transfer pipe, which is not conducive to improving production efficiency. In order to improve the efficiency of heat transfer tube maintenance and sludge cleaning, this paper presents a method of detecting and cleaning heat transfer tube sludge based on the visualization display system of scaling data. In order to construct a visual display system, the management and visual display method of sludge data are studied, and on the basis of the analysis of the function of maintenance and cleaning of steam generator heat transfer tube, The data management structure of steam generator heat transfer tube sludge and the function module of sludge visualization display are designed, and the classical 3D volume data visualization algorithm Marching Cube is studied. On this basis, the visualization rendering graphics of the whole heat transfer tube sludge distribution are realized quickly. Based on the above research, this paper presents a visual display algorithm of steam generator heat transfer tube sludge. Based on the secondary development of Hoops, the visualization display system of steam generator sludge data is constructed. The visual display of heat transfer tube sludge of steam generator is verified by introducing the measured data of heat transfer tube sludge detection. The results show that the method proposed in this paper based on visualization for maintenance and repair of heat transfer tube sludge of steam generator can serve for the cleaning of sludge of steam generator, guide the maintenance of steam generator conveniently, and improve the maintenance efficiency. Reduced maintenance costs.
