| 中文摘要 | 为了解决细煤粉污染焦炭及焦油的品质问题,基于气固流态化原理,搭建TG-100型悬浮式涡流筛分中试装置,进行煤颗粒的粒度分级试验研究.以500μm为目标粒径,考察不同流化风速对煤颗粒分级效果,监测分级前后煤颗粒的水分变化.结果表明:随着流化风速的提高,参与流化的颗粒直径不断增大,煤颗粒的干燥效果不断提高,当入口风速为55 m/s(流化风速为1.84m/s)时,分级效果最佳,细煤颗粒中500μm以下粒级含量高达99.7%,粗煤颗粒中500μm以下粒子含量仅为28.7%,分级后水分降低了44.58%,表明煤颗粒分级过程还具有一定的干燥效果.; In order to prevent the accumulation of fine coal particles in the coking production,which would seriously deteriorate the quality of coke and tar,experimental studies based on the principle of gas-solid fluidization were conducted on a pilot scale separation apparatus,a TG-100-type suspension vortex fluidized bed,to segregate the coal particles with different sizes.To select coal particles of similar density in the target size of 500 μm to investigate different coal particles sorting effects caused by different fluidization speeds.Besides,the dehydration process during the separation was also revealed.The results showed that with the increase of air flow rate,the diameter of the particles in fluidization increased obviously,and the drying of the coal particles became more remarkable.When the air velocity reached to 1.84 m/s,the best separation results could be obtained.The coal particles smaller than 500 μm were up to99.7%in the fine product,while as low as 28.7%in the coarse product.The moisture in the fuel could be reduced by 44.58.Both effective segregation and dehydration were obtained in the processing. |
