【摘要】：近年來，大氣污染已成為人們最關心的環(huán)境問題之一。作為火力發(fā)電主體的燃煤發(fā)電廠，它在運轉的過程中會排放大量的氮氧化物。而氮氧化物是大氣主要污染源之一，因此控制電廠燃煤排放的氮氧化物刻不容緩。作為解決火電廠氮氧化物排放問題的核心工具——煙氣脫硝，便隨之成為火電行業(yè)需要深入探究的一項關鍵性工藝。目前國內電廠脫硝改造呈現(xiàn)出逐漸擴張的趨勢，脫硝普及率在逐年增加，電廠脫硝技術的應用前景是十分看好的，如何選擇出一種更有效實用、更節(jié)能減排的脫硝工藝便成為首要考慮的一個方面�；诖�，本文對火力發(fā)電脫硝工程項目進行相關的綜合評價研究。 本文首先介紹了國內外四種主流的火力發(fā)電廠脫硝技術工藝，，其次介紹了綜合評價相關的理論及其方法，在此基礎上，以火電廠脫硝工程項目為研究對象，對脫硝方案及綜合評價方法進行了全面深入地研究，從生態(tài)環(huán)境，經(jīng)濟效益以及技術三個方面建立火力發(fā)電脫硝方案綜合評價指標體系，運用層次分析法和模糊三角數(shù)相結合的方法構建脫硝項目方案選擇綜合評價模型，確定各指標權重值。 最后，以西柏坡電廠脫硝工程項目為例進行系統(tǒng)地綜合評價分析，通過脫硝項目綜合評價模型對其脫硝技術的改造提出了相關建議，最后重點進行了環(huán)境效益分析和經(jīng)濟效益分析，從而為我國同類型火力發(fā)電廠脫硝工程項目方案選擇綜合評價提供一定的理論依據(jù)和方法的參考。
[Abstract]:In recent years, air pollution has become one of the most concerned environmental problems. Coal-fired power plant, as the main part of thermal power generation, emits a lot of nitrogen oxides in the process of operation. Nitrogen oxide is one of the main air pollution sources, so it is urgent to control the emission of nitrogen oxides from coal-fired power plants. Flue gas denitrification, as the core tool to solve the problem of NOx emission from thermal power plants, has become a key process for further exploration in thermal power industry. At present, the trend of denitrification in domestic power plant is gradually expanding, the popularization rate of denitrification is increasing year by year, the application prospect of denitrification technology in power plant is very promising, how to choose a more effective and practical denitrification technology, More energy-saving and emission reduction denitrification process has become a primary consideration. Based on this, this paper carries on the related comprehensive evaluation research to the thermal power denitrification project. This paper first introduces four kinds of domestic and international technology of denitrification in thermal power plants, and then introduces the related theories and methods of comprehensive evaluation. On the basis of this, the project of denitrification in thermal power plants is taken as the research object. The comprehensive evaluation index system of denitrification scheme for thermal power generation is established from the aspects of ecological environment, economic benefit and technology. The comprehensive evaluation model of denitrification project scheme selection is constructed by the combination of AHP and fuzzy triangular number, and the weight value of each index is determined. Finally, taking the denitrification project of Xibaipo Power Plant as an example, the paper makes a systematic comprehensive evaluation and analysis, and puts forward some relevant suggestions on the improvement of denitrification technology through the comprehensive evaluation model of the denitrification project. Finally, the environmental benefit analysis and economic benefit analysis are carried out, which provides a certain theoretical basis and method reference for the comprehensive evaluation of the project selection of denitrification project in the same type of thermal power plant in China.
