旋风叶轮式分离器性能试验研究

Experimental Research on the Performance of a Cyclone Impeller Type Separator

通过冷态试验研究了旋风叶轮式分离器的性能。结果表明:旋风叶轮式分离器的分级分离效率与颗粒粒径呈指数递增关系,出粉均匀性好;出粉粒度随总分离效率升高而减小;给料浓度和叶轮转速影响总分离效率的大小,随着给料浓度的增大,总分离效率先增大后减小,当给料浓度C=0.08kg/m3时,总分离效率最高;随着叶轮转速的提高,总分离效率先减小后增大,当叶轮转速S=120r·min-1时,总分离效率最低;实际应用中,可以通过改变叶轮转速来调节旋风叶轮式分离器的出粉粒度。

In order to study the separation performance of a cyclone impeller type separator, a series of experiments were conducted in a cold test rig. The grade separation efficiency of the separator and particle size is monotonic increasing exponential function. The escape powder has good uniformity. With higher overall separation efficiency, the powder fineness decreases. Feed concentration and impeller speed affect the overall separation efficiency size. As feed concentration C increases, the efficiency first increases and then decreases, the transition point is about C=0.08kg/m^3. As impeller speed S increases, the efficiency first decreases increases and then increases, the transition point is about S=120 r.min^-1. In practical application, changing the impeller speed can regulate the escape paticle size of the sparator.
