摘要
Abstract
[Objective]Municipal sludge incineration is currently a mainstream technology for achieving sludge reduction and harmless disposal,the stable operation and efficacy of its flue gas treatment system to ensure both environmental compliance and long-term economic viability of projects.In response to increasingly stringent environmental requirements and industry challenges,this paper systematically investigates different flue gas treatment processes for sludge incineration and their development trends.[Methods]By analyzing the actual operation data of a typical 600 t/d sludge pyrolysis-gasification and incineration coupling project over the past three years,the concentration and key characteristics of major pollutants in the flue gas are summarized.Differences in flue gas pollutant emission limit indices among sludge incineration projects of different regions and scales are compared.Engineering cases in Xi'an and Chengdu are also utilized to analyze typical issues in the operation of flue gas systems and corresponding countermeasures.[Results]Generated flue gas is characterized by high humidity,and severe corrosivity-particularly sulfuric/hydrochloric acid dew point corrosion-so special attention must be paid to the corrosion resistance of materials when selecting equipment for the flue gas treatment system.Currently,there is no unified national emission standard for sludge incineration flue gas in China,and future standards would tend to be stricter in terms of pollutant control categories and limit requirements.This paper further elaborates on the selection basis and applicable conditions of current mainstream flue gas treatment processes.[Conclusion]Against the backdrop of the"dual carbon"goal,the technology for treating sludge incineration flue gas will develop in the directions of integration with carbon capture and storage(CCS)technology,synergistic control of multiple pollutants,and energy utilization.This paper can provide empirical evidence for the process design,operation optimization,and standard formulation of similar projects,and promote the industry towards low-carbonization,resource utilization,and sustainable development.关键词
