摘要
介绍了气力输送中变径管道的设计方法和主要参数(临界速度、管径、压降、气体流速、变径位置、变径角)的确定。通过分析实验数据,说明采用逐渐增大管径的变径管道可以有效地降低输送管道中的气速、压损和能耗。
The stepped pipeline design method and main parameters（including critical velocity, bore, pressure drop, conveying air velocity, step location, step angle）in pneumatic conveying were presented. By analysizing the empirical data,the lower velocity profile, low pressure drop and less energy waste could be effectively achieved in a stepped pipeline of increasing bore.
