摘　　要：为揭示脱硫塔内SO_2的浓度和脱硫效率变化,利用双膜理论为基础,以SO_2为研究对象,针对SO_2在脱硫塔内的传质理论,建立SO_2的吸收模型,利用Matlab分析脱硫塔内SO_2的浓度变化和脱硫效率随高度的变化,通过模型可以看出脱硫效率随高度的增加呈缓慢的增长,和试验结果较为吻合。In order to know about time change between time concentration of SO2 and desulfurization effect in the spray scrubber, time absorbing model of SO2 is set up based on the bio- film theory and mass transfer theol. Matlab method is used to analyze the change of the concentration of SO2 and desulfurization effect with the change of height and we can see that desulfurization effect show slow curve increase with the increase of height and it agrees with the experimental results.
