摘    要:液体连续相撞击流(LIS)具有高效微观混合、强烈压力波动和促进过程动力学等对分子尺度过程极有价值的性质.本文在浸没循环撞击流反应器(SCISR)中深入研究了这些性质及其规律,进行了反应-沉淀法制取多种"超细"和纳米材料的实验,制得粒径更细小,分布更窄,形貌可控的超细粉体;研发了"无旋立式循环撞击流反应器"等多种基于应用...

关 键 词:撞击流  微观混合  压力波动  反应器  结晶器

Abstract:Liquid-continuous impinging streams(LIS)have the excellent features of enhancing micromixing,strong pressure fluctuation and promoting process kinetics,which are extremely valuable for processes occurring on molecular scale.The authors investigated these features;and also studied the preparation of severalultrafineand nano materials experimentally by reaction-precipitation in LIS,and obtained products of smaller particles with narrower size distribution and controlled appearance.Several devices employing LI...
Keywords:impinging streams  micromixing  pressure fluctuation  reactor  crystallizer
