摘要/Abstract

摘要： 在小型紫外光-鼓泡床反应器中,对UV/H₂O₂氧化联合Ca(OH)₂吸收同时脱除燃煤烟气中NO与SO₂的主要影响因素[H₂O₂浓度、紫外光辐射强度、Ca(OH)₂浓度、NO浓度、溶液温度、烟气流量以及SO₂浓度]进行了考察。采用烟气分析仪和离子色谱仪分别对尾气中的NO₂和液相阴离子作了检测分析。结果显示:在本文所有实验条件下,SO₂均能实现完全脱除。随着H₂O₂浓度、紫外光辐射强度和Ca(OH)₂浓度的增加,NO的脱除效率均呈现先大幅度增加后轻微变化的趋势。NO脱除效率随烟气流量和NO浓度的增加均有大幅度下降。随着溶液温度和SO₂浓度的增加,NO脱除效率仅有微小的下降。离子色谱分析表明,反应产物主要是SO₄^2-和NO₃^-,同时有少量的NO₂^-产生。尾气中未能检测到有害气体NO₂。

Abstract: In a lab-scale UV-bubbling column reactor,the effects of several influence factors[H₂O₂ concentration,UV radiation intensity,Ca(OH)₂ concentration,NO concentration,gas flow rate,solution temperature and SO₂ concentration]on simultaneous removal of NO and SO₂ from flue gas by using combination of UV/H₂O₂ oxidation with Ca(OH)₂ absorption were studied.Besides,the NO₂ in the treated gas after reactor and the anions in the liquid phase were measured by using flue gas analyzer and ion chromatography(IC),respectively.The results indicated that under all experimental conditions,100% removal of SO₂ was achieved.With increasing H₂O₂ concentration,UV radiation intensity and Ca(OH)₂ concentrations,NO removal efficiency greatly increased at first,but then changed only a little with further increase of H₂O₂ concentration,UV radiation intensity and Ca(OH)₂ concentration.NO removal efficiency was greatly decreased with the increase of NO concentration and flue gas flow rate.Increasing solution temperature and SO₂ concentration slightly decreased NO removal efficiency.The anions in the liquid phase were mainly SO^<sup>2-4 and NO₃^-,and a small amount of NO₂^-.The harmful NO₂ in the treated gas after reactor was not detected.
