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SO42-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 SO2- 4 and NO3-

and a small amount of NO2-.The harmful NO2 in the treated gas after reactor was not detected.
