一种高炉出铁口可拆卸式除尘罩
本技术涉及一种除尘装置,尤其涉及一种高炉出铁口可拆卸式除尘罩。
技术介绍
高炉出铁场烟尘污染严重,每产生1t铁,约产生2.5kg烟尘。出铁口是出铁场内散发污染物的主要烟尘源,约占总污染物的30%,做好出铁口的有效除尘,对改善高炉炉前工作条件,减少烟尘对大气的污染有重要作用。高炉出铁口多采用侧吸加顶吸相结合的方式,现场也有顶吸罩。为了保铁口机和泥炮的正常使用,顶吸罩距离出铁口较高,烟尘捕集效果差。由于出铁口是开放空间,风机会将周围空气卷吸进去,增加风机的吸气量,耗电大而且烟尘捕集效果差。同时烟尘在上升过程中扩散逃逸,当出铁场有侧向风或者出铁口出现喷溅时,高压烟气会冲出烟尘捕集区,极易造成烟尘失控现象的发生。固定式除尘罩会影响出铁口设备作业和设备维修,可移动或可旋转的烟罩,由于离出铁口较近,容易受到高温烟尘的冲刷,设备故障率高,寿命短,而且出现侧向风时,收集烟尘效果很差。
技术实现思路
本技术旨在克服高炉出铁口除尘罩现有缺陷,提供一种高炉出铁口可拆卸式除尘罩,以便高效完成高炉出铁口烟尘捕集的任务。本技术除尘罩包括:罩顶,侧板,面板,立柱,横梁 ...
