一种煤调湿加热系统
本技术涉及一种加热系统,尤其是一种煤调湿加热系统,属于煤处理领域。
技术介绍
现有的备煤车间分卸、配煤两个工序;卸煤主要接收外来煤种的卸、堆取工作,配煤主要承担焦炉煤料运输、粉碎工作;但是堆料场露天存储,加之煤种细、粘、板结及水分超高,致使配合粉碎后水分高,影响焦炉热态指标,加剧装炉操作,增加焦炉耗热,垮饼等劳动量加大。煤调湿工艺以煤气燃烧热量作为主要热源对湿煤进行烘干,烟道废气通过混风炉进入煤调湿转筒为辅热,二者结合形成热气流与翻滚的煤料进行热交换而达到蒸发水分的作用,此操作能取得降点降水效果。经分析查看,焦炉烟道废气存在20.06%H20,混合后经20米转筒进行热交换,煤气燃烧高温热量与低温烟道气混合必然导致温度降低,同时蒸发烟道气中水蒸气耗费大量热量;不仅降低混合气的温度,甚至将大量水分带入煤中,使得煤水分不能最大方式去除,因此有必要对150-180°废气重新加以利用,进而,在现有基础上,急需一种煤调湿加热系统。
技术实现思路
