摘要
某铅冶炼厂烟气处理系统具有一定的不稳定性,二氧化硫、氮氧化物排放达不到环保要求。本文介绍了原烟气处理工艺有机胺脱硫技术的基本情况,对当前工艺存在的问题进行探讨,并提出了改进措施,包括调整脱硫烟气及胺液走向、增加臭氧脱硝系统,确保环保设施与生产能力相适应,并对改造后的烟气处理工艺从胺液选择、烟气净化、胺液脱盐、烟气温度等方面进行优化。烟气处理系统改造优化后,二氧化硫、氮氧化物均稳定达标。
The flue gas treatment system of a lead smelter has certain instability,and the emission of SO_(2) and NO_(x) can't meet the environmental protection requirements.This paper introduced the basic situation of organic amine desulfurization technology in the original flue gas treatment process,discussed the problems existing in the current process,and put forward improvement measures,including adjusting the direction of desulfurization flue gas and amine liquid,increasing ozone denitrification system,and ensuring that environmental protection facilities are compatible with production capacity.The flue gas treatment process after the transformation was optimized from the aspects of amine liquid selection,flue gas purification,amine liquid desalination,flue gas temperature and so on.After the transformation and optimization of the flue gas treatment system,the emissions of SO_(2) and NO_(x) are up to standard.
