摘　　要：为了提高沉降室内的降尘能力,本研究利用Solidworks软件设计出一种分离式沉降室。并利用SimulationXpress和Solidworks FlowSimulation进行了流体仿真,利用Solidworks Simulation进行静力仿真,对其进行优化设计。通过仿真发现,该种结构的沉降室,不仅可以利用重力将粉尘与气流进行分离,还可以在沉降室内形成气体涡流,利用离心作用将粉尘脱离,从而增强降尘效果。通过检测内部气流均速与降尘板长度之间的关系,得出降尘板长度应当在4 5004 700 mm之间。通过静力仿真分析,应当对沉降室边角和顶部区域5处进行加固处理。In order to improve the dust reduction ability of the settling chamber, a square separate settling chamber was designed by SolidWorks software. The fluid simulation is carried out by using simulationpress and SolidWorks flow simulation, and the static simulation is carried out by using SolidWorks simulation to optimize the design. Through the simulation, it is found that the settling chamber with this structure can not only separate the dust from the air flow by gravity, but also form gas vortex in the settling chamber, and separate the dust by centrifugal action, so as to enhance the dust reduction effect. By detecting the relationship between the average velocity of the internal air flow and the length of the dust suppression plate, it is concluded that the length of the dust suppression plate should be between 45004700 mm. Through the static simulation analysis, the settlement chamber corner and top area 5 should be reinforced.
