【摘要】：华电潍坊发电有限公司（以下简称“潍坊公司”）2×670MW机组于2003年11月开工建设，2006年12月两台机组投产，配套上海锅炉厂设计制造的型号为SG-2102/25.4-M954超临界参数变压运行直流锅炉，锅炉尾部配置菲达环保设计制造的双室四电场电除尘器。依据《火电厂大气污染物排放标准》（GB13223-2011）相关规定，由于潍坊市属于重点控制地区，按新标准要求自2014年7月1日起，潍坊公司烟尘最高允许排放浓度为20mg/m3。为保证烟尘排放浓度达标，潍坊公司计划对除尘器进行改造。通过对除尘器出口温度和除尘效率的测试，在分析和实验的基础上，，设计改造方案，使除尘效果达到新的国家一级排放标准。通过对电除尘器改造方案的设计和分析论证，达到熟练掌握工业工程分析方法的目的。本文主要工作： 1.收集并整理了摸底试验结果以及电除尘器日常运行情况，并分析了结果后对电除尘器改造的必要性以及可行性进行了详细的阐述。 2.根据不同的研究方向与实际要求提出改造方案。 3.对各方案进行了详细对比论述。 4.综合分析提出了最优改造方案，并对相应的配套工程提出了改造方案。本文探讨了电袋除尘器在工业应用的推广性与可行性。电除尘技术是目前国内外比较成熟和应用比较广泛的发电厂除尘技术。袋式除尘器有着良好的除尘效果，两者结合必然会产生前所未有的效果。复合式除尘器结合了电除尘和布袋除尘的优点，必然会成为发电企业在今后的升级改造中的趋势而得到广泛的应用。
[Abstract]:Huadian Weifang Power Generation Co., Ltd (hereinafter referred to as "Weifang Company") began construction of 2 脳 670MW units in November 2003 and put into operation two units in December 2006. The design and manufacture model of Shanghai Boiler Plant is SG-2102/25.4-M954 supercritical parameter variable pressure running once-through boiler. Boiler tail is equipped with Fida environmental protection design and manufacture of two-chamber four-electric field electrostatic precipitator. According to the relevant regulations of GB13223-2011), Weifang belongs to the key control area, according to the new standard requirement, the maximum allowable emission concentration of smoke and dust in Weifang Company is 20 mg / m ~ (3) from July 1, 2014. In order to ensure that the concentration of soot emission reaches the standard, Weifang Company plans to retrofit the dust collector. Through testing the outlet temperature and dust removal efficiency of the dust collector, on the basis of analysis and experiment, the retrofit scheme is designed to make the dust removal effect up to the new national first class discharge standard. Through the design and analysis of the retrofit scheme of the electrostatic precipitator, the purpose of mastering the analysis method of industrial engineering is achieved. The main work of this paper is: 1. This paper collects and arranges the test results and the daily operation of the electrostatic precipitator, and analyzes the necessity and feasibility of the transformation of the electrostatic precipitator. 2. According to different research directions and practical requirements, the modification scheme is put forward. 3. The comparison and discussion of each scheme are given in detail. 4. The optimal retrofit scheme is put forward by comprehensive analysis, and the corresponding supporting project is put forward. This paper discusses the popularization and feasibility of ESP in industrial application. Electric dust removal technology is a relatively mature and widely used dust removal technology in power plants at home and abroad. Bag dust collector has a good dust removal effect, the combination of the two will inevitably produce unprecedented results. Combined with the advantages of electric dust collection and cloth bag dust removal, the composite dust collector will inevitably become the trend of power generation enterprises in the future upgrading and transformation and will be widely used.
