对烧结机主抽风系统管径的探讨

烧结工艺中,主抽风系统是一个主要的组成部分,其中风道管径的确定十分重要,本文介绍一下主抽风系统管径的确定的方法。

烧结主排气管落地布置方案设计与优化

烧结主抽风系统是烧结工程的核心系统之一。为实现烧结烟气的粗除尘,烧结工程设计需在主排气管下部布置灰箱、双层卸灰阀及粗颗粒粉尘输送皮带等设备,导致烧结厂房整体高度大幅增加,进而增加工程投资。本文从厂房设计角度出发,提出主排气管落地布置的新方案,并讨论新方案对烧结系统设计、工程投资及产量的影响,对烧结工程优化设计有指导意义。结果表明:将主排气管置于地面,在排气管内设置埋刮板输送机,调整烧结卸矿斗和环冷机给料溜槽的高度,可在满足除尘工艺需求的同时将厂房高度整体降低约7 m。落地的主排气管采用钢筋混凝土结构取代钢结构后,节省钢筋砼量约为24.6%,取消主排气管下部的灰箱及双层卸灰阀后,烧结系统漏风率降低3.5%,产量提高约5.4%。新方案的实施可大幅降低工程的投资费用和后期运行费用。

The Applications of High-voltage variable frequency speed regulation System in Main Exhauster of Sintering

Main Exhauster is one of the main equipment of sintering production. It needs to consume a lot of electricity. Therefore, the system＇ s reconstruction for energy-saving will effectively reduce electricity for the production. The paper takes an iron and steel enterprise that had successfully transformed the synchronous motors of main exhauster of sintering as an example, which describes the application of high-voltage variable frequency speed regulation system in main exhauster of Sintering, so as to provide a reference for other iron and steel enterprises.
