在分析SLK5500型选粉机结构和分级机理的基础上,通过构建选粉机分级室模型,根据计算流体力学理论,运用DPM模型与非稳态算法求解颗粒运动轨迹,阐述了不同粒径的颗粒群在分级室内的运动特性.考察了选粉机分级室内的流场速度分布,并捕捉颗粒计算了风量和转速对细粉颗粒产率和80μm筛余的影响,模拟结果与实验结果基本相符,验证了模型的可靠性.
Based on the analysis of the structure and classification mechanism of SLK5500 classifier, this paper builds the classification chamber model of classifier, and uses DPM model and unsteady state algorithm to calculate the trajectories of the particles according to computational fluid dynamics (CFD) theory. The particles of different particle sizes This paper investigates the velocity distribution of the flow field in the classification chamber of the classifier and captures the particles and calculates the effect of air volume and speed on the fine powder yield and 80μm sieve residue.The simulation results are in good agreement with the experimental results, Verify the reliability of the model.
