气态悬浮焙烧炉返灰系统的设计优化

摘要

氢氧化铝焙烧是氧化铝生产的一个重要环节。通过分析以往气态悬浮焙烧炉返灰系统在使用中出现的问题，提出了改进的意见和方案，并在新的焙烧炉设计中进行了实施。经多年生产实践，效果显著。%Aluminum hydroxide calcining is an important link in alumina production .By analyzing previous some problems arisen in the use of dust return system for gas suspended calicner , some improvment suggestions and so-lutions have been put forward , and they were implemented in the new design of calciner ,which was effective by years of practices .
