ABSTRACT

The pseudo-fluid characteristics of the gas–solid separation fluidized bed provide a set of feasible methods for the dry separation of coal. The equipment used in the development of dry separation technology is receiving increasing attention around the world, because it generates no pollution during the separation process. However, the industrial application of related technologies using multi-component, complex fluidization equipment has met with considerable resistance. In recent years, a series of advances and achievements has been made in the study of the structural design, fluidization characteristics, and coal separation performance of the gas–solid separation fluidized bed. With respect to the historical development of gas–solid separation fluidized equipment and related progress in basic theoretical research, this paper summarizes the recent developments of the common gas–solid fluidized bed, vibratory fluidized bed, and magnetically stable fluidized bed. We comprehensively investigate the factors influencing the fluidized bed, and identify some problems that must be addressed to further advance the large-scale industrialization of the gas–solid separation fluidized bed.

气固流化床干法选煤技术综述

摘要

气固分离流化床的拟流体特性为煤的干法分离提供了一套可行的方法。干式分离技术开发所使用的设备由于在分离过程中不会产生污染,因此在世界范围内受到越来越多的关注。然而,使用多组分、复杂流化设备的相关技术的工业应用遇到了相当大的阻力。近年来,在气固分离流化床的结构设计、流化特性、煤分离性能等方面的研究取得了一系列进展和成果。关于气固分离流化设备的历史发展及相关基础理论研究进展,本文总结了普通气固流化床、振动流化床和磁稳定流化床的最新进展。全面考察了流化床的影响因素,明确了进一步推进气固分离流化床规模化产业化需要解决的问题。
