摘要
传热管内的流振旋转螺旋能实行在线、连续、自动除垢防垢，并且结构简单、成本低、通用性强，是传热设备防治污垢很有效的新技术。本文扼要地介绍了该新技术的原理。
The rotating and vibrating spiral in heat transfer tube is a new high efficient technique to remove and prevent fouling in heat transfer equipment,which not only can clean automaticly in line but also has simple structure, low price and is used widely. This paper discribes its structure pinciple, cleaning capability and flow dynamics preperty experiments.
