摘　　要：为考察石灰石的脱硫活性对SO2吸收的影响,基于气体吸收的双膜理论,建立了通过石灰石种类和粒径分布来预测喷淋塔脱硫性能的数学模型,并进行了相应的试验研究.该模型中,石灰石种类的不同对SO2吸收的影响通过石灰石的表面反应速率常数来解释;对于同种石灰石,粒径越小,比表面积越大,溶解越快,越有利于SO2的吸收.In order to investigate the effects of limestone reactivity on SO2 absorption, the effects of limestone type and particle size distribution on SO2 absorption were studied with a numerical model based on the two film theory of gas absorption and experimental method. The surface reaction rate constant variations accounted for the differences among different types of limestone. As for limestone of the same type, the smaller its particles were, the larger its Specific area was, the faster it dissolved and the more SO2 was absorbed.
