摘要
在光伏硅料制备中,传统坩埚装料方式依赖人工经验,存在堆积密度不均、装料效率低且坩埚破损率高的问题。本文提出了基于CFD-DEM多物理场耦合与模糊PID控制的装料优化模型。通过CFD-DEM模型揭示颗粒运动规律,使用AltairEDEM^(TM)软件进行仿真与实验,确定最优倾倒角度为45°,结合模糊PID算法动态调节坩埚运动参数。该模型使装料效率提升25%,坩埚破损率从2%~5%降至0.3%以下,实现了硅料均匀堆积与装料过程的精准控制,为光伏硅料制备的自动化与高效化提供了技术方案。
In the preparation of photovoltaic silicon materials,the traditional crucible loading method relies on manual experience,which has problems such as uneven packing density,low loading efficiency,and high crucible damage rate.This article proposes a loading optimization model based on CFD-DEM multi physics field coupling and fuzzy PID control.Revealing particle motion patterns through CFD-DEM model,using Altair EDEM^(TM) Simulate and experiment with software to determine the optimal tilt angle of 45°,and dynamically adjust the crucible motion parameters using fuzzy PID algorithm.This model improves the loading efficiency by 25%,reduces the crucible damage rate from 2%to 5%to below 0.3%,and achieves precise control of the silicon material uniform stacking and loading process,providing a technical solution for the automation and efficiency of photovoltaic silicon material preparation.
