【技术实现步骤摘要】
一种烟气换热装置
本技术涉及一种烟气换热装置。
技术介绍
工业炉窑排放的高温烟气温度约为600-1000℃,所带走的热量占燃料热量的40-60℃,高温烟气内含有大量的灰尘,若是直接排放到空气中会对大气造成空气污染,这就需要对高温烟气进行灰尘收集处理,由于高温烟气温度较高,若是让高温烟气直接进入到灰尘收集装置内,势必高温烟气会对灰尘收集装置造成破坏,这就需要对高温烟气进行降温,并对高温烟气进行灰尘预处理。
技术实现思路
针对上述缺陷,本技术的目的在于提供一种结构简单,能够对高温烟气进行降温处理,并能够收集高温烟气内部分灰尘的一种烟气换热装置。为此本技术所采用的技术方案是:包括烟气入口罩和烟气出口罩,所述烟气入口罩下端设有上封板,所述烟气出口罩上端设有下封板,上封板与下封板之间设有与烟气入口罩和烟气出口罩相通的若干烟气管,上封板与下封板之间的前后两侧分别设有一个支撑板,若干烟气管位于两个支撑板之间,若干烟气管的左侧设有防护网,若干烟气管的右侧设有支架,支架上安装有若干轴流风机,烟气出口罩为漏斗形结构,烟气出口罩的下端安装有卸灰阀,烟气出口罩的侧壁上设有烟气出口,烟气入口罩的上端设有烟气入口。作为上述技术方案的进一步改进,所述烟气管为不锈钢管,烟气管的内壁为光滑内壁。作为上述技术方案的进一步改进,所述烟气出口处设有吸风机,所述吸风机为变频脉冲吸风机。作为上述技术方案的进一步改进,所述烟气出口罩内设有位于烟气出口处的挡灰板。本技术的优点是:本技术结构简单,安装方便,通过采用本技术结构,能够对高温烟气进行初级降温处理,使其满足进入收尘装置的条件,并能够对高温烟气进行初级收尘 ...
