通过采用CFX软件,以实验回转窑内的气相场、颗粒相为研究对象,建立含钒页岩实验回转窑内焙烧过程的数值模拟模型,获得在正常的操作状态下窑内烟气温度场、流场、组分场、颗粒的运动轨迹的分布情况.计算结果显示,该窑内形成两个相对高温区,在焙烧带窑内的烟气及颗粒的运动速度增大,能较准确地反应窑内的焙烧过程,对研究开发高效的含钒页岩复合焙烧专用回转窑具有重要意义.
Through the use of CFX software, taking the gas phase and the particle phase in the experimental rotary kiln as the research object, a numerical simulation model of the roasting process in a rotary kiln containing vanadium shale was set up to obtain the temperature field of the flue gas in the kiln under normal operating conditions, Flow field, component field and distribution of particle trajectory.The calculation results show that two relatively high temperature zones are formed in the kiln, and the flue gas and particle velocity in the roasting zone kiln increase, which can react more accurately The roasting process in the kiln is of great significance for the research and development of an efficient rotary kiln for composite roasting of vanadium-bearing shale.
