Abstract： A novel cyclone tube design is obtained on the basis of structural and dimensional optimization of Shell-type cyclone tube. By using isokinetic sampling method, the particle concentration distribution in the novel cyclone tube is measured and analyzed. The experimental result demonstrates that discharge dust cone with slots has better separation effect, flowguide cone can reduce short circuit flow greatly and makes small grain separated because of the strong inertia. Particle concentration decreases with axial coordinates increasing above the ashpit, which indicates that the inner revolving flow has a strong secondary separation effect. The estimation on particle grade efficiency suggests that the novel cyclone tube can separate particles of 7 mm completely, for small particles of 3~7 mm, its grade separation efficiency is above 86%. On contrast, Shell-type cyclone tube can only separate particles larger than 10 mm completely in the same operation condition. This work provides a necessary basis for structural improvement, dimensional optimization and even industrial application of cyclone tube.
