旋转气流是旋风器流场的重要特征。有效工作区是准自由涡区,其特性为urn=常数。旋风器工作性能的严重弊病是除尘空间狭窄,能量利用很不充分。
Swirling airflow is an important feature of the cyclone flow field. The effective work area is a quasi-free vortex area with the characteristic urn = constant. Serious drawbacks to the performance of a cyclone are its narrow space for dust collection and inadequate energy use.
