通过灰渣在滚筒冷渣器内的运动实验,建立了滚筒内灰渣的轴向运动模型,研究了滚筒转速、倾斜角、填充度和滚筒直径等参数对灰渣平均停留时间的影响。结果表明:滚落状态下灰渣在滚筒内停留时间约为滑移状态的1.5倍,灰渣间混合良好;在其它条件不变的情况下,随转速和倾斜角、直径的增大或填充度的减小,灰渣在滚筒内的停留时间减小;转速越大灰渣间混合越强,填充度越大混合越弱。
Based on the experiments of slag in the roller slag cooler, the model of axial movement of the ash in the roller was established. The influence of the rotating speed, tilting angle, filling degree and cylinder diameter on the average residence time of the ash was studied. The results show that the residence time of the slag in the drum is about 1.5 times as much as that of the slipping state and the mixture of ash is good under the condition of rolling off. Under other conditions, with the increase of speed and inclination angle, Degree of reduction, ash residue in the drum to reduce the time; the greater the speed of the mixture between the ash the stronger, the greater the degree of mixing weaker mixing.
