Abstract:	摘要： The goal of this study is to evaluate the performance of a moving granular bed filter designed to filter out dust particles. We investigate the flow patterns of the filter granules, and the filtration efficiency under different inlet dust concentrations, but with a fixed filtration superficial velocity and mass flow rate of filter granules. All filtration system experiments were performed at room temperature. A vertical shift of louvers on the inlet or outlet wall of the filter could be an appropriate solution to diminish the stagnant zones. The results of a study of the flow patterns and velocity fields of filter granules in a 2-D cross-flow moving granular bed system with vertically shifting louvers is presented. In addition, the results of cold tests show that using a higher dust concentration of 15,000ppmw and a fixed-bed mode, the overall porosity of the filter granules decreased and the filter resistance and the filtration efficiency increased, with an increase in the amount of smaller-sized filter granules in a 3-D bed. 出版者： Elsevier Ltd 出版日期： 2016-10-15 出處： Fuel (Guildford), 2016-10, Vol.182, p.174-187 版權： 2016 Elsevier Ltd 識別號： ISSN: 0016-2361 識別號： EISSN: 1873-7153 識別號： DOI: 10.1016/j.fuel.2016.05.106
