- Title:
- Design of Flue Gas Treatment Technology for Municipal Sludge Independent Incineration Project
- Keywords:
- sludge incineration; flue gas treatment; process design
- 摘要:
- 通过污泥泥质对焚烧烟气中的主要污染物，即颗粒物、NOx、酸性气体、重金属的初始设计浓度进行分析预测，结合项目需执行的烟气排放标准，对不同污染物的去除率提出要求。针对不同污染物，考虑其特性、去除率需求和运行成本，选择最经济合理的烟气处理工艺。结合国内处于运行状态的污泥焚烧项目所采用的烟气净化工艺，提出适用于市政污泥独立焚烧项目的烟气处理工艺技术路线，为未来更多类似项目的工艺设计提供参考。
- Abstract:
- This paper introduced the flue gas emission standards for domestic sludge incineration project, predicted the initial design concentration of major pollutants such as particulate matter, NOx, acidic gas and heavy metal in incineration flue gas according to sludge component, and proposed the removal rates of different pollutants in combination with the emission standards to be implemented in the project. For different pollutants, the most economical and reasonable flue gas treatment process was selected by considering its characteristic, removal rate and operating cost. The flue gas treatment technologies suitable for municipal sludge independent incineration projects were proposed based on the flue gas treatment technology being applied in domestic sludge incineration projects. The results aim to provide reference for the process design of more similar projects in the future.
