摘　　要：SDA脱硫塔上、下旋流片结构直接影响气流分布和脱硫效率。文章采用Fluent模拟软件,针对F100脱硫塔的结构特点,建立脱硫塔与旋流片的物理模型,研究不同旋流片结构条件下的脱硫效率变化规律。旋流片长间比、个数影响旋流强度,进而对脱硫效率有较大影响。结果表明:随着旋流片长间比的增加,脱硫效率先升高再趋于平稳。结合实际条件,上旋流片长间比在2.8时,脱硫效率最高为85.71%;上旋流片片数在36个时,脱硫效率最高为85.82%;下旋流片长间比在3时,脱硫效率最高为85.69%;下旋流片片数在24个时,脱硫效率最高为85.65%。The structure of upper and lower swirl plates in SDA desulfurization tower directly affects the airflow distribution and desulfurization efficiency.Based on the structure characteristics of F100 desulfurization tower,the physical model of desulfurization tower and swirl plate was established by using Fluent simulation software to study the change rule of desulfurization efficiency under different swirl plate structure conditions.The ratio and number of swirl segments affect the swirl intensity and thus the desulfurization efficiency is greatly affected.The results show that the desulfurization efficiency increases with the increase of swirl VAT length ratio and tends to be stable at last.Combined with the actual conditions,the maximum desulfurization rate is 85.71%when the slice length ratio of superswirl is 2.8.The maximum desulfurization rate is 85.82%when the number of upper swirl plates is 36.The maximum desulfurization rate is 85.69%when the ratio of current swirl to slice length is 3.The maximum desulfurization rate is 85.65%when the number of swirling flow plates is 24.
