摘要：为了找出影响旋风除尘器压力损失和分离效率的因素,优化除尘器的设计和制造,借助计算流体力学Fluent软件,采用正交模拟法,分析不同的升气管插入深度、圆锥筒体直径以及入口宽度对标准Stairmand型旋风除尘器的分离效率和总压降的影响。结果表明:当升气管插入深度为80 mm,圆锥底部直径为100 mm,入口宽度为30 mm时,除尘器总压降最小;当升气管插入深度为120 mm,圆锥底部直径为50 mm,入口宽度为30 mm时,除尘器分离效率最高。

Abstract：To find out the factors influencing the cyclone pressure loss and separation efficiency， the design and manufacture of filters were optimized. With the aid of computational fluid dynamics Fluent software， using the orthogonal simulation method， the effect of different trachea insertion depths， cone cylinder diameters and entrance widths on the separation efficiency and total pressure drop of the standard Stairmand type cyclone was analyzed. The results show that when the trachea insertion depth is 80 mm， the bottom diameter of cone is 100 mm， the entrance is 30 mm， and the minimum total pressure drop can be achieved. When the trachea insertion depth is 120 mm， the bottom diameter of the cone is 50 mm，the entrance width is 30 mm， and the dust separation efficiency is the highest.
