摘要
石灰颗粒的内孔结构对石灰吸收HCl气体的反应进程起着决定作用 .用Bethe网络来代表石灰颗粒内孔隙之间的连接性 ,用分形概念来描述内孔形状和表面的不规则性 ,从而建立全面考虑内孔连接特征和孔壁形状的不规则性的内孔结构模型 ,并对反应过程进行模拟计算 .通过在 2 0 0～ 30 0℃范围内 ,石灰颗粒吸收HCl气体的反应率随时间进展的试验数据与数值模型预测相对比 。
Inner-pore structure of lime particles plays a fundamental role on reaction process between limes and gaseous HCl. In this paper Bethe lattice has been used to represent connectedness of pore space, and fractal concept has been adopted to describe the irregularity of pores. Thus a theoretical model for describing both the connectedness and the irregularity of pore structure of lime particles has been proposed. Reaction process of HCl with lime sorbents under the temperature range of 200～300℃ was predicted with this model. The model predictions of conversion-time behaviors of quick lime and slaked lime particles coincide with experimental data.
