| 摘 要： | 采用酸滴定法，在实验室小试装置中实验研究了湿法烟气脱硫中石灰石溶解特性。试验了2个不同来源的石灰石。发展了一个基于质量传递控制基础上的数学模型，用于描述石灰石溶解过程。模型预测的石灰石转化率以及颗粒尺寸分布和pH值对石灰石溶解速率的影响能很好地与实验数据吻合。较小的石灰石颗粒尺寸、较低的pH值和CI^-主体浓度有利于石灰石溶解速率的提高。

| Abstract: | The characterization of limestone dissolution for wet flue gas desulfurization was investigated in a laboratory batch apparatus using acid titration.Two limestones of different origin were tested.A mathematical model,based on mass transport controlling,was developed to describe limestone dissolution process.Model predictions were in good agreement with experimental data such as the degree of limestone conversion,and the effects of particle size distribution (PSD) and pH value on limestone dissolution rate.Smaller particle size of limestone,lower pH value and Cl - bulk concentration are beneficial to the increase of limestone dissolution rate. |
