本文介绍了大冶有色冶炼厂4#干燥窑尾气收尘改造和运行效果。前言大冶铜精矿干燥方式采用回转式干燥窑,热介质为粉煤燃烧产生高温空气,在干燥窑内,高温空气与铜精矿顺流接触,干燥过程中产生水蒸气及粉尘随尾气一起进入收尘系统处理后排空。该工艺于2003年10月建成投产,干燥精矿能力为80~100吨/小时,承担着铜精矿干燥的主要任务,原尾气收尘工艺为旋风收尘及水沫风收尘两级收尘工艺,但由于烟气量
This article describes the Daye non-ferrous smelter 4 # drying kiln tail gas dust collection transformation and operation results. Preface Daye copper concentrate drying method using rotary kiln, heat medium for the pulverized coal combustion to produce high temperature air, in the kiln, high temperature air and copper concentrate downstream contact, the drying process produces steam and dust along with the exhaust gas Into the dust collection system emptying after treatment. The process was put into operation in October 2003, the capacity of dry concentrate is 80-100 tons / hour, bear the main task of copper concentrate drying, the original exhaust gas collection process for cyclone dust collection and Shuimo wind dust two levels of dust collection Process, but due to the amount of flue gas
