离心鼓风机在硫酸系统中的应用

Application of centrifugal blower in sulphuric acid system

介绍了离心鼓风机基本动力学方程、特性曲线、影响特性曲线的因素以及离心鼓风机的选用原则。在使用中，要求离心鼓风机进口含尘量≤１００ｍｇ／ｍ３，电动机功率一般为设计工况点所需功率的１１５～１３倍，可在风机进口管道设置一蝶阀以满足风机启动和小范围的性能调节。

Abstract The basic dynamic equation, characteristic curve, influencing factor on characteristic curve and selection principle of centrifugal blower are introduced. In actual application, it is required that dust of inlet gas is <100*!mg/m 3 and operation power is 1.15～1.3 times design power. A butterfly valve can be installed in suction for start and regulation of blower.
