摘要
为了实现烧结烟气的深度治理,基于逆流式活性炭脱硫脱硝工艺,宁钢建设了一套采用模块化设计、脱硫脱硝分层、活性炭循环利用等先进技术的脱硫脱硝系统。系统平稳运行后,净化烟气中二氧化硫、氮氧化物、颗粒物排放指标分别为5mg/m^(3)、46mg/m^(3)、8mg/m^(3),实现了烧结烟气的超低排放。同时,对该系统运行过程中存在的问题给出了解决措施,为该技术的广泛应用提供了参考。
In order to achieve the deep control of sintered flue gas,based on the anti-current activated carbon desulfurization and denitrification process,Ningbo Steel has built a system of desulfurization and denitrification using advanced technologies such as modular design,desulfurization and denitrification stratification,and activated carbon recycling.After the smooth operation of the system,sulphur dioxide,nitrogen oxide and particulate matter emission indexes of 5mg/m^(3),46mg/m^(3),8mg/m^(3)in the flue gas are purified.At the same time,some measures are given to solve the problems in the operation of the system.
