摘　　要：对自行研制的斜板湿式除尘脱硫器，利用计算流体力学（CFD）中的fluent软件，选择k-ε模型和SIMPLE算法，对其内部气流流场进行数值模拟．结果表明，入口处、斜板处存在旋涡，湍流剧烈．旋涡的存在延长了气流的停留时间，增加了相间接触机会，可减少和消除死角．最后，选取入口管和出口管的某断面进行实验验证．结果表明：入口、出口某断面处实验与模拟值吻合较好，两者的相对误差在1％～3％．The airflow field of the bevel edge wet desulfurization ＆ dust catcher, designed by our experimental team, was simulated through the fluent software of the computational fluid dynamics（CFD）, where the calculation was based on k-ε-equation model and SIMPLE algorithm. The simulation showed the turbulent flow was intense at the bevel edges and in the inlet tube, the vortex prolonged the residence time of the airflow, increased the contact opportunity of the phases and decreased or eliminated the existent dead zones. And some experiments were carried out. The experiment results agreed well with simulation, and the relative error was 1%-3%.
