Abstract

Abstract:

Thermogravimetric analysis (TGA) was used to study the thermodynamic behaviors of pyrolysis and incineration of six typical components of MSW, and to explore the interaction between PVC which is the dioxin precursor and other components of MSW. The effects of different components on promoting or inhibiting the decomposition of PVC were quantitatively analyzed by combining the calculation of superposition rate of calculated curve and experimental curve and the fitting of kinetic parameters. The results show that adding paper, wood chips, cardboard and PE can reduce the formation of dioxin in PVC incineration process, and PE has the best inhibition effect on the formation of dioxin.

Key words: Municipal solid waste, Incineration, Pyrolysis, Kinetics, Dioxin inhibition

摘要：

采用热重分析法研究了生活垃圾中6种典型组分的热解及焚烧热力学行为，探究了二噁英前驱物PVC与其他垃圾组分间的交互行为。结合计算曲线和实验曲线叠加率的计算以及动力学参数的拟合，定量分析了不同组分对PVC分解的促进或抑制作用。结果表明，在PVC焚烧过程中加入纸片、木屑、硬纸板和PE均能减少二噁英的生成，其中PE抑制二噁英生成的效果最佳。
