摘要
从分级流场构建的角度对离心式气流分级机进行梳理分类,按照分级区旋涡转轴的不同分为竖直旋涡分级机和水平旋涡分级机,并对几种代表机型的流场特征及研究进展进行了剖析,指出竖直旋涡分级机的研究较多,而水平旋涡分级机的研究相对较少,强调了合理构建与组合分级流场和淘洗流场的重要性,展望了离心式气流分级机的研究前景。
In perspective of flow field organization, the classifiers were analyzed, and regrouped as vertical vortex classifiers and horizontal vortex ones according to the rotation axis of the vortex in classifying chamber. Several typical air classifiers were discussed on their flow field characteristics and research advances. Compare to the vertical vortex classifier, there was currently not sufficient research on the horizontal vortex classifiers. To improve the classification performance of the classifiers, suggestions of giving full consideration to the design and interaction of the gas flows for particle classification and elutriation were proposed. It is expected the centrifugal air classifiers will have a deeper development in future.
