中文摘要	应用分形几何原理,研究了飞灰颗粒的粒径分布特征及其粒径的分形分布函数,并将分形维数作为描述飞灰颗粒粒径分布的特征参数,从而建立了飞灰粒径分布特征及其与重金属吸附能力的量化关系.应用分形分布函数讨论了不同粒径分布的飞灰颗粒对燃煤烟道气中汞的自吸附脱除效应.利用粒径分布分维数可以定量研究不同粒径分布的飞灰颗粒系统中重金属污染物的吸附能力.; Fly ash can be regard as synthetic particle system and its particle-size-distribution presents the characteristics of fractal.Traditional characteristic parameter——specific-surface-area could not reflect the adsorption ability of fly ash particle systems which have different particle-size-distribution completely.Fractal characteristics of particle-size-distribution-function of fly ash are studied in this paper by using the theories of fractal geometry.Fractal dimension is chosen as a parameter to describe the characteristics of fly ash particle size distribution.Fractal-distribution-function of fly ash which establishes the quantity relationship between fractal characteristics of particle size and its adsorption ability is given subsequently.The self-adsorption-effect of fly ash particle to mercury in flue gas are discussed by using the fractal-distribution-function.Fractal dimension of particle-size-distribution is put forward in this study for investigation the fly ash adsorption ability of heavy metal in quantity.
