【摘要】：玻璃是我国居民生产生活的基础原材料,它的生产制造也显得尤为重要。我国作为玻璃建材消费大国,玻璃产量也位居世界前列,河北省玻璃产量占全国总产量约25%。同时,根据玻璃生产工艺的要求,含硫含氮原料需要在炉窑中高温熔融,在它的生产工艺流程中会产生的大量的烟粉尘、二氧化硫和氮氧化物等污染物质,故该行业已被国家列为治理大气污染重要行业之一。河北省作为玻璃行业生产大省,区域玻璃行业污染治理技术应用也多种多样,各技术治理成效也参差不齐,如何科学有效选择技术经济最优的大气污染防治技术已是玻璃行业迫切需求解决的问题。因此,本研究主要通过调研河北省代表性玻璃企业,建立适用玻璃行业的评估指标体系,运用层次分析法确定各指标权重,采用模糊综合评价法筛选出行业最佳可行技术,具体研究结果如下:(1)通过专家咨询和企业调查,构建了玻璃行业除尘脱硫脱硝三种技术评估指标体系,指标体系主要包括技术性能指标、经济成本指标、环境效应指标等三类准则层指标,指标层中除尘指标体系共16项指标,脱硫指标体系共17项指标,脱硝指标体系共15项指标;(2)通过运用层次分析法确定了除尘脱硫脱硝指标体系中各指标权重,除尘脱硫脱硝指标权重排序均为:环境效应指标技术性能指标经济成本指标,其中除尘指标准则层权重分别为0.534、0.250、0.216,脱硫指标准则层权重分别为0.610、0.236、0.154,脱硝指标准则层权重分别为0.592、0.207、0.201;(3)在企业现场调查和资料查阅的基础上进行指标内容数据汇总,采用模糊综合评价的方法,建立了各指标隶属函数,将各指标定量化,并筛选出了除尘脱硫脱硝最佳适用技术,其中除尘技术中以高温静电除尘技术为最佳,脱硫技术以双碱法技术为最佳,脱硝技术以SCR(选择性催化还原)技术为最佳,同时针对技术得分稍低的布袋除尘技术、石灰石石膏法脱硫技术及SNCR(非选择性催化还原)技术等提出技术改进建议。
[Abstract]:Glass is the basic raw material for the production and life of Chinese residents, and its production and manufacture is especially important. As a large country of glass building materials consumption, China's glass output ranks among the top in the world, and Hebei's glass output accounts for about 25 percent of the country's total output. At the same time, according to the requirements of the glass production process, the raw materials containing sulfur and nitrogen need to be melted at high temperature in the furnace, and a large amount of pollutants such as smoke dust, sulfur dioxide and nitrogen oxides will be produced in its production process. Therefore, the industry has been listed as one of the important industries to control air pollution. Hebei Province is a big producer of glass industry. The application of pollution control technology in regional glass industry is also varied, and the effects of each technology are also uneven. How to scientifically and effectively select the best technology for preventing and controlling air pollution is an urgent problem for glass industry. Therefore, this study mainly through the investigation of representative glass enterprises in Hebei Province, set up a suitable glass industry evaluation index system, using AHP to determine the weight of each index, using fuzzy comprehensive evaluation method to screen out the best feasible technology in the industry. The specific research results are as follows: (1) through expert consultation and enterprise investigation, three evaluation index systems of dedusting, desulphurization, denitrification and denitrification in glass industry are constructed. The index system mainly includes technical performance index, economic cost index, and so on. There are 16 indexes of dust removal index system, 17 indexes of desulphurization index system and 15 indexes of denitrification index system. (2) the weight of each index in the index system of dedusting, desulphurization and denitrification is determined by using the analytic hierarchy process. The order of the weight of the index is: the environmental effect index, the technical performance index, the economic cost index. Among them, the weight of the dust removal index is 0.534U 0.250m 0.216, the desulfurization index is 0.6100.236U 0.154, and the denitrification index is 0.592U 0.2070.201; (3) the index content data is summarized on the basis of the on-the-spot investigation and data reference of the enterprise, and the membership function of each index is established by using the method of fuzzy comprehensive evaluation, and each index is quantified. The optimum technology of dust removal, desulfurization and denitrification was screened out, in which high temperature electrostatic dust removal technology was the best, double alkali technology was the best technology, and SCR (selective catalytic reduction) technology was the best technology. At the same time, suggestions for technical improvement such as bag dust removal technology, limestone gypsum desulphurization technology and SNCR (non-selective catalytic reduction) technology are put forward.
