【摘要】：进入21世纪以来,我国火力发电厂的烟气脱硫装置的建设、改造发展态势迅猛,但也存在一些问题,诸如部分机组脱硫装置的设计缺陷、施工企业的规范意识不强、技术水平不够、管理经验不足,导致脱硫设施运行不稳定、可靠性差,脱硫效率达不到要求的现象还比较突出。因为脱硫项目在施工工艺上的特殊性、工艺流程的复杂性、参建方较多的特点,完成的项目频频出现质量问题,达不到净化烟气的效果。因此,脱硫改造工程项目的质量管理势在必行,这就需要对脱硫改造工程质量进行有效的综合评价,对它的质量管理情况做出合理的分析,发现其中的薄弱环节,并且提出针对性的改进措施,让脱硫改造工程的质量管理水平不断提高,实现脱硫改造工程项目质量问题的有效控制,为类似项目质量管理提供理论支持。论文首先介绍了本课题的研究背景及意义,在全面了解了国外和国内在质量管理方面所做的研究的基础上,系统阐述了质量和质量管理等相关概念,并且阐述了脱硫工程改造质量管理的相关理论及方法。其次对陡河发电厂脱硫改造工程项目的基本情况进行了介绍,详细分析了该工程项目实施过程中建立的质量管理体系,并在此基础上,从横向、纵向两个角度分别构建了评价指标体系。然后,结合两大指标体系,将层次分析法(AHP)和模糊评价法结合,创建评价模型;并以陡河发电厂脱硫改造工程为实例,对其质量管理进行了综合评价,验证了模型的符合性与可行性。最后,对评价结果进行分析和比对,指明了该工程质量管理的薄弱环节,提出了有针对性的改进措施,为类似的工程项目质量管理评价指明方向,提供了参考依据。
[Abstract]:Since the beginning of the 21st century, the construction of flue gas desulfurization units in thermal power plants in China has developed rapidly, but there are still some problems, such as the defects in the design of the desulfurization units of some units, and the lack of a strong sense of specification in construction enterprises. Insufficient technical level and insufficient management experience lead to unstable operation of desulfurization facilities, poor reliability and insufficient desulfurization efficiency. Because of the particularity of the construction process, the complexity of the technological process and the more characteristics of the participating parties, the quality problems frequently appear in the completed projects, which can not achieve the effect of purifying the flue gas. Therefore, the quality management of desulphurization and transformation project is imperative. It is necessary to make an effective comprehensive evaluation on the quality of desulphurization and transformation project, to make a reasonable analysis of its quality management, and to find out the weak links in it. The paper also puts forward the corresponding improvement measures to improve the quality management level of desulphurization and transformation project, to realize the effective control of the quality problem of the desulfurization and transformation project, and to provide theoretical support for the quality management of similar projects. Firstly, this paper introduces the research background and significance of this topic. On the basis of a comprehensive understanding of the research on quality management both at home and abroad, this paper systematically expounds the related concepts of quality and quality management. The related theories and methods of quality management of desulfurization project are expounded. Secondly, the basic situation of desulphurization and transformation project in Douhe Power Plant is introduced, and the quality management system established during the implementation of the project is analyzed in detail. The evaluation index system is constructed from two vertical angles. Then, combining the two index systems, the analytic hierarchy process (AHP) and the fuzzy evaluation method are combined to establish the evaluation model, and the comprehensive evaluation of its quality management is carried out by taking the desulphurization and retrofitting project of Douhe Power Plant as an example. The conformance and feasibility of the model are verified. Finally, the evaluation results are analyzed and compared, the weak links of the project quality management are pointed out, and the corresponding improvement measures are put forward, which provide a reference basis for the similar project quality management evaluation.
