摘要
简介了选择性非催化还原(SNCR)脱硝的反应机理和主要影响因素,综述了各种添加剂对SNCR脱硝过程影响的研究进展。不同添加剂对SNCR脱硝过程影响的作用机理不同,但都能有效扩宽反应的温度窗口,使其往低温方向移动,提高SNCR在低温段的脱硝率。通过分析添加剂的作用机理,为研究脱硝效果更好的添加剂提供理论依据,以提高脱硝率、减少二次污染。
The reaction mechanisms and the primary influencing factors of selective non-catalytic reduction(SNCR)denitrification are introduced.Research progress of the effects of various additives on SNCR denitrification process are reviewed.Although different additives has different mechanism to SNCR denitrification process,all additives can broaden the width of temperature window,lower the temperature window and increase the denitrification rate in the low-temperature phas of SNCR.Through analyzing the mechanism of the additives affecting SNCR denitrification process,theoretical basis for exploring better additives in the future is provided,so as to achieve higher denitrification rate and reduce the secondary pollution.
