| 摘 要： | 除尘器常采用雾化除尘原理,组合喷嘴雾化除尘效果好,但其结构及流动情况比较复杂。选用德国BAAS-MS-11-130°井下除尘喷嘴为研究对象,应用CREO软件对喷嘴进行三维实体建模,并应用ANSYS软件中的网格生成工具ICEM CFD对其进行网格划分,导入到ANSYS-FLUENT软件中进行边界条件的设置,选择VOF模型,对其进行数值模拟分析。分析喷嘴的入口速度、入口直径、旋流器内部斜孔的直径以及角度、旋流器个数和喷嘴主体喷口孔径等参数变化对喷嘴喷雾效果的影响。

| Abstract: | For pray dust,multi-jet is better than single nozzle,however its internal structure and flow situation are more complex.Taking the German BAAS-MS-11-130° nozzle as example,the 3D modeling software CREO was applied to build its model,ANSYS ICEM was used to mesh it.Then ANSYS FLUENT software was used to carry on the numerical simulation.Changing the size parameters of nozzle,including the inlet velocity,inlet diameter,cyclone bore diameter and internal oblique angle,the number of cyclones and the main jet nozzle aperture and other parameters,the influences on the nozzle spray effect were analyzed. |
