Flow Simulation of Transfer Station and Optimization of Skirtboard

Abstract

Belt conveyor system for bulk material in large plants usually needs amounts of transfer station, which are one of most important dust generation areas. The dust generation mechanism of transfer station is that bulk material dropping down from high site causes air flow and small particle material move with air. The skirtboard of transfer station can restrain dust to some extent through airproofing its flow. Gas-solid flow in transfer station is simulated with Computational Fluid Dynamics (CFD) method in this paper. Based on the simulation results of traditional rectangular skirtboard, an optimized skirtboard is proposed. Contrast of two plans’ simulation results indicates that the new one can restrain dust obviously, which is significant for material saving and environment protecting.
