The heat of gas can obviously improve the drying effect.
【技术实现步骤摘要】
一种新型高效烘干炉
本技术涉及一种新型高效烘干炉,特别是涉及一种用于潮湿的萤石精粉的新型高效烘干炉。
技术介绍
萤石又称氟石、氟石粉、萤石粉,是一种矿物,等轴晶系,其主要成分是氟化钙(CaF2)氟化氢生产过程中的主要原料萤石精粉进厂后通常是潮湿的,在进入反应炉前必须通过烘干炉烘干,以去除其中的水分和油分。潮湿的萤石精粉在烘干炉内与高温烟气通过直接接触的方式进行烘干,高温烟气由造气工段生产的半水煤气燃烧提供。在烘干过程中,湿萤石粉在安装于烘干炉筒体内壁上锯齿形扬料板的作用下,虽然基本能够散开,分布于烘干炉内与高温烟气充分接触,但炉体中间部位会形成空洞,导致热源(高温烟气)直接从空洞通过至后工序烟气处理系统,造成热量的极度浪费。
技术实现思路
本技术目的在于提供一种新型高效烘干炉,对传统的萤石精粉烘干炉内部结构进行技术改造,通过在烘干炉中间部位增加扬料板,与炉内边缘锯齿形扬料板相互配合,使物料快速散开,增加其换热面积,有效提高物料与高温烟气的换热效率。本技术解决上述技术问题的技术方案如下:一种新型高效烘干炉,所述烘干炉包括炉体,所述烘干炉还包括边缘扬料板、支撑体和中间扬料板; ...
