以粒径为0.9mm的铜颗粒为流化颗粒,常温水为流化介质,在截面为59.2×15.6mm的矩形床中,对液固导流管喷动流化床的流型及流型转变进行实验了研究。通过对床层压降流量曲线的分析并结合实验观察,确定了液固导向管喷动流化床的流型及流型的划分,提出了流型图。研究结果对进一步开展导流管喷动流化床电极研究有重要的参考意义。 Taking the copper particles with a diameter of 0.9mm as the fluidized particles and the normal temperature water as the fluidizing medium, the flow pattern and the flow pattern of the fluidized solidified draft tube in a spouted fluidized bed in a rectangular bed of 59.2 × 15.6mm in cross section Change the experimental study. Through the analysis of the bed pressure drop flow curve and the experimental observation, the flow pattern and the flow pattern division of the liquid-solid guide tube in the spouted fluidized bed are confirmed, and the flow pattern is proposed. The research results have important reference significance for the further research on the spout fluidized bed electrode.
