摘要

利用Fluent软件中的离散相模型

对吸收塔内部气液两相流的流场进行三维数值模拟。选用k-ε模型作为计算模型

采用Simple算法进行计算。结果表明

改变进气管道对塔内压差影响较大

优化模型可改善塔内流场分布

使塔内气液接触更加充分。在加入喷淋层后

吸收塔上部气体速度变得均匀

塔内总烟气阻力减小。

Abstract

Discrete phase model in Fluent software was applied to conduct three-dimensional numerical simulation on flow field of gas-liquid two-phase flow in the absorber.The k-ε model and Simple algorithm were adopted in the calculation.The results showed that

the optimized model can improve the flow field inside the absorber

make the gas contact with liquid more fully.Changing the inlet pipeline had great effect on the gas-liquid mixing degree and internal pressure.After adding the spray layer

the gas velocity at top of the absorber became uniformity and the flue gas resistance decreased.
