摘要

为了增加旋流板分离器的断面气速

减小分离粒径

使其适应水泥生料粉预热器的要求

对分离器空间三维旋转流场进行了测定和分析.根据实测流场的特点

对其结构作了如下改进:加挡板以防止颗粒的二次夹带;加筋以消除灰环

从而使断面气速增加到3m/s

临界分离粒径减小到10～15μm

本文运用流场实测结果所推导的旋流板分离器的临界分离粒径公式及所测压降数据

可供生产上参考.

Abstract

In order to improve the rotating-flow-plate separator to remove smaller particles at higher gas velocities

especially for preheating cement raw mix

a series of three-dimensional measurements were conducted and the experimental results were analyzed. Based on the flow profiles thus elucidated

the following improvements were made: a baffle plate was installed around the rotating-flow-plate to prevent particles from backflow

and a rib along the wall of the separator was added to counteract dust-ring whirling near the wall. These improvements resulted in lowering the critical diameter of the particles separated to 10-15μm at a gas velocity of 3 m/s. Formulae for critical particle diameters and data on pressure drop of the improved separator are presented.
