摘要: 針對工業界提出的高溫除塵問題,采用固體顆粒床除塵方式,對用砂粒作為過濾介質的可行性和實用性進行了研究.通過模擬高爐一次除塵后的含塵氣體濃度,進行了固體顆粒床除塵器的等溫實驗,探索了氣體過濾速度、過濾床層厚度對除塵器除塵效率和床層壓力損失的影響.根據實驗結果,確定了最佳過濾速度和過濾床層厚度.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.
