摘　　要：低碳目标的提出对于炼焦行业的发展和变革有着重要的影响。研究将以低温选择性催化还原法(Selective Catalytic Reducation,SCR)+石灰-石膏双碱法脱硫方法为例,通过脱硫和脱硝试验设置分析其排放效率。结果表明,SCR反应器的最佳反应温度为380℃。在满足硫排放标准的情况下,液气比设置区间为2.0~2.5 L/m^(3),钠离子浓度设置区间为0.55 mol/L。研究通过试验验证了炼焦行业烟气脱硫和脱硝技术具有良好的应用效果,可实现较高的脱硝和脱硫效率,为炼焦行业的低碳目标践行提供了建设性技术参考。The proposal of low-carbon targets has a significant impact on the development and transformation of the coking industry.The study will take the low-temperature selective catalytic reduction(SCR)+lime gypsum double alkali desulfurization method as an example,and analyze its emission efficiency through desulfurization and denitrification experiments.The results indicate that the optimal reaction temperature for the SCR reactor is 380℃.Under the condition of meeting sulfur emission standards,the liquid to gas ratio is set within the range of 2.0~2.5 L/m^(3),and the sodium ion concentration is set within the range of 0.55 mol/L.The research has verified through experiments that the flue gas desulfurization and denitrification technologies in the coking industry have good application effects and can achieve high denitrification and desulfurization efficiency,providing constructive technical references for the low-carbon goal implementation in the coking industry.
