介绍了液固流化床粗煤泥分选技术在粗煤泥分选中的的优势和缺点。针对TBS分选机存在的缺点,阐述了其基本分选原理和分选结构,并介绍了国内外液固流化床分选粗煤泥技术的发展与应用情况,分析了液固流化床粗煤泥分选技术的发展思路、现状和趋势。分析表明,液固流化床分选粗煤泥技术的发展趋势是,提高液固流化床分选机在目前工业应用中2～0.25mm粒级范围内的分选效果和处理量,同时要减少粒度对分选的影响,强化其按密度分选作用,提高其在宽粒级的分选效果,进一步扩大其分选范围。
The advantages and disadvantages of coarse slime separation technology of liquid-solid fluidized bed in the process of coarse slime separation are introduced. In view of the shortcomings of TBS separator, the basic principle of sorting and the sorting structure are expounded. The development and application of the technology of separating coarse slime from liquid-solid fluidized bed at home and abroad are introduced. Development Strategy, Status Quo and Trend of Coarse Slime Separation Technology. The analysis shows that the development trend of liquid-solid fluidized bed separation of coarse slime technology is to improve the separation and treatment capacity of liquid-solid fluidized bed classifier within the range of 2 ~ 0.25mm in the current industrial application, at the same time To reduce the impact of particle size on sorting, to strengthen its sorting by density, to improve its sorting results in a wide range of particle size to further expand its sorting range.
