SO2和NOX 一种烟气脱硫脱硝一体化系统设计 摘 要 污染是造成大气污染的主要原因。随着新的污染物排放标准的颁布， 烟气脱硫脱硝技术面临着前所未有的压力和挑战。如何经济、有效地提高脱硫脱硝 效率，降低SO2和NOX的排放量，成为大气环境污染控制工作者研究的热点问题。 本文针对各种同时脱硫脱硝技术进行了分析对比，通过对比各种不同工艺的优 缺点，最后确定采用 SCR 和 CuO 同时脱硫脱硝技术。根据设计参数，对 SCR 脱硝 反应器和脱硫反应器进行设计计算，又对氨储存罐，喷氨格栅等辅助设备进行了初 步的设计选型。最后绘制了 SCR 和 CuO 同时脱硫脱硝一体化技术的系统图，并进 行造价估算。基本达到了设计要求。 关键词 ：烟气，脱硫脱硝，一体化  Abstract  I 一种烟气脱硫脱硝一体化系统设计  SO2 and NO X pollution is the main reason for air pollution With the new emission standards promulgated, flue gas desulphurization and denitrification facing unprecedented pressures and challenges. How to cost-effectively improve the efficiency of desulfurization and denitrification, reducing SO2 and NOX emissions, atmospheric pollution control workers become a hot research issue. In this paper, a variety of simultaneous desulfurization and denitrification were analyzed and compared, by comparing the advantages and disadvantages of different techniques, and finally determine the use of SCR, CuO simultaneous desulfurization and denitrification technologies. According to the design parameters of SCR denitrification and desulfurization reactor design and calculation, and the ammonia storage tanks, ammonia injection grid and other auxiliary equipment for the preliminary design and selection. Finally draw the SCR, CuO simultaneous desulfurization and denitrification systems diagram, and conduct cost estimates. Basically meet the design requir ements.
