Isothermal Experiment Research of a High Temperature Granular Bed Filter

摘要: 针对工业界提出的高温除尘问题,采用固体颗粒床除尘方式,对用砂粒作为过滤介质的可行性和实用性进行了研究.通过模拟高炉一次除尘后的含尘气体浓度,进行了固体颗粒床除尘器的等温实验,探索了气体过滤速度、过滤床层厚度对除尘器除尘效率和床层压力损失的影响.根据实验结果,确定了最佳过滤速度和过滤床层厚度.

Abstract: A kind of filter with sand as the percolation medium for dust-removing were discussed and designed for isothermal experiment. Through the experiment by this fiter simulating the BF top gas sub-dedusting, the effect of the thickness of the fiter layer and the filtration gas velocity upon the dust-removing efficiency and the pressure loss was investigated. Based on the experimental results, the optimized thickness of the filter layer and the optimized velocity of filtration gas were confirmed.
