摘要
在分析传统石煤焙烧设备的基础上,提出一种适用于石煤提钒的"导风墙-干燥床"式焙烧竖炉。通过与钒钛磁铁矿焙烧竖炉进行对比,阐述了石煤焙烧竖炉独有的结构特点,定量给出了其结构参数和操作参数,并建成了国内第一台真正意义上的石煤焙烧竖炉。实践表明:石煤焙烧竖炉是一种技术可靠、经济可行的石煤提钒焙烧设备,它具有炉内温度气氛可控、利用系数较高、单位产品能耗较低、钒回收率较高等优点。对探索我国石煤提钒焙烧的新设备、促进石煤提钒行业的快速发展具有重要意义。
Based on analyses on traditional stone coal quipped with internal vertical air channels （IVAC） and roasting equipments, a roasting shaft furnace e- drying bed for vanadium extraction from the stone coal was developed. Through comparison with the roasting shaft furnace for vanadium titaniferous magne- tite, the unique structure characteristics of the roasting shaft furnace for stone coal was elaborated, and structural and operating parameters of the latter was given. Furthermore, the first roasting shaft fumace for stone coal in China was established on this basis. The practice shows that the roasting shaft furnace is a re- liable and economical roasting equipment for vanadium extraction from stone coal. It has many advantages, including controllability of temperature and atmosphere in furnaee, high utilization coefficient, low energy consumption per unit product, and high vanadium recovery rate. This paper aims at introducing a new fur- nace type for vanadium extraction from stone coal and promoting the development of vanadium industry.
