【摘要】 基于Fluent软件对比分析了喷淋塔内两层旋流板布置时,旋流板内外层叶片数量分别为12、18、24时喷淋塔内部流场的分布情况。结果表明,喷淋塔内烟气流场分布状况基本趋势相同,但也存在一定的差异。通过对比喷淋塔内速度场、中心截面的烟气流动状况、主要吸收区域三个水平截面速度平均值和标准差,综合考虑速度场和温度场分布状况以及喷淋塔进出口压降,对于所研究的喷淋塔塔型,确定了内外层叶片数为18较为合适。

【Abstract】 Based on the Fluent, the distribution of flow field inside the spray tower with two swirl plates in the spray tower was arranged and the number of inner and outer vanes of the swirl plate twelve, eighteen, and twenty four were analyzed, respectively. The results showed that the distribution of smoke flow field in the spray tower was basically the same, but there were also some differences. By comparing the velocity field in the spray tower, the flow of flue gas in the central section, the mean value and standard deviation of the velocity of three horizontal sections in the main absorption area, considering the distribution of velocity and temperature fields and the pressure drop at the inlet and outlet of the spray tower, the number of inner and outer leaves was determined to be 18 of this spray tower type.
