Abstract

Three-phase fluidized bed flotation column (TFC) is a new type of separation flotation method with high efficiency and low energy consumption. In this paper, the industrial experimental effect of TFC is investigated. The influence of operating parameters on the flotation separation effect was investigated by adjusting the operating parameters such as gas velocity, liquid velocity, and bed height. In addition, when the sampling depth and sampling radius are increased, the ash content in the selection zone increases with it. The relationship between the amount of mid-coal circulation and the ash content was also investigated. The ash content of refined coal gradually decreased from 10.28 % to 9.28 % when the amount of middle coal circulating was increased from 0 % to 50 % of the feed. This study explores the separation effect of TFC from industrial experiment perspective, which lays a good foundation for future industrial-scale applications.

用于工业实验研究的新型三相流化床浮选柱评估

三相流化床浮选柱（TFC）是一种高效、低能耗的新型分离浮选方法。本文研究了 TFC 的工业实验效果。通过调整气速、液速、床层高度等操作参数，研究了操作参数对浮选分离效果的影响。此外，当取样深度和取样半径增大时，选择区的灰分含量也随之增加。还研究了中煤循环量与灰分含量之间的关系。当中煤循环量从进料的 0 % 增加到 50 % 时，精煤的灰分含量从 10.28 % 逐渐下降到 9.28 %。该研究从工业实验的角度探索了 TFC 的分离效果，为未来工业规模的应用奠定了良好的基础。

期刊介绍： Powder Technology is an International Journal on the Science and Technology of Wet and Dry Particulate Systems. Powder Technology publishes papers on all aspects of the formation of particles and their characterisation and on the study of systems containing particulate solids. No limitation is imposed on the size of the particles, which may range from nanometre scale, as in pigments or aerosols, to that of mined or quarried materials. The following list of topics is not intended to be comprehensive, but rather to indicate typical subjects which fall within the scope of the journal's interests: Formation and synthesis of particles by precipitation and other methods. Modification of particles by agglomeration, coating, comminution and attrition. Characterisation of the size, shape, surface area, pore structure and strength of particles and agglomerates (including the origins and effects of inter particle forces). Packing, failure, flow and permeability of assemblies of particles. Particle-particle interactions and suspension rheology. Handling and processing operations such as slurry flow, fluidization, pneumatic conveying. Interactions between particles and their environment, including delivery of particulate products to the body. Applications of particle technology in production of pharmaceuticals, chemicals, foods, pigments, structural, and functional materials and in environmental and energy related matters. For materials-oriented contributions we are looking for articles revealing the effect of particle/powder characteristics (size, morphology and composition, in that order) on material performance or functionality and, ideally, comparison to any industrial standard.
