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.
