摘要
我国有 2 / 3以上的煤炭资源分布在西部等缺水地区 ,西部大开发中煤炭的分选洁净及利用十分必要。本文在分析气固流化床特性的基础上 ,对流化床干法分选理论进行了深入研究 ,揭示了空气重介质流化床的分选机理。试验结果表明 :空气重介质流化床可有效地分选煤炭 ,为我国西部煤炭资源的分选洁净提供了一条途径。
More than 2/3 of Chinas coal is deposited in the western region where there is a lack of water,Coal cleaning is of great importance for the development of the region.The paper introduces the theory of coal dry seperation and the mechanism of fluidized bed using gas as heavy medium.Test result shows that fluidized bed dry seperation is a suitable method to clean coal in the western region of China.
