重质颗粒流态化研究现状与展望
Current status and prospects of research on fluidization characteristics of high-density particles
摘要
Abstract
Fluidized bed technology is widely used in industry.Industrial processes such as natural uranium conversion,direct reduction ironmaking,and chemical chain combustion use heavy particles with a particle density of more than 4.0 g/cm3.However,in traditional chemical and energy industries,lightweight fluidized bed particles with smaller density are widely used.This article reviews the application background of high-density particle fluidization technology in some industries,which particle densities are beyond 4.0 g/cm3,and explores the impact of high-density particle fluidization quality on system performance.Subsequently,the article reviews the research progress in high-density particle fluidization,highlighting that both experimental measurements and numerical simulations indicate significant differences in the fluidization behavior between high-density and low-density particles.However,existing studies on the fluidization characteristics of high-density particles remain insufficient,particularly regarding the flow characteristics and differences compared to low-density particles.Finally,combined with the needs of related industrial processes,this article focuses on the basic research content of heavy particle fluidization that should be supplemented in the near future.关键词
