摘　　要：吸收塔设计是实现湿法烟气脱硫技术国产化和自主化的关键。采用Pro/Engineer软件建立吸收塔空塔模型,并利用计算流体力学软件Ansys CFX对吸收塔气相动力流场进行模拟,探讨并比较了不同吸收塔出口形式对其产生的影响,对比了吸收塔内压力、矢量速度分布情况,可为后续吸收塔流场模拟及优化提供指导。The absorption tower design is key technology for realization of localization and independence of the wet FGD technology.Using software Pro / Engineering,the empty tower model of absorption tower was established.Using the computational fluid dynamics software Ansys CFX,the gaseous phase dynamic flow field in absorption tower was simulated.The influence of different outlet forms of absorption tower on its performance was discussed and compared,and the distribution of the pressure and the vector velocity in tower were compared,which provide some guidance for subsequent simulation and optimization of flow field in absorption tower.
