摘要：本文介绍了一种新的气-气快速混合技术。它利用射流与多孔板撞击所产生的流动特性,实现气-气间的快速混和。本文对影响混合质量的各种参数,诸如:动量比M、多孔板阻力系数ζ、喷管与多孔板间的距离和喷管直径比H/d、混合长度与反应器直径比L/D 等,分别进行了讨论。试验在直径300mm 的冷模中进行.并在直径800mm 的冷模中验证放大规律。研究结果表明,只要选取适当的参数,气-气混合后,在L/D=1处截面上浓度的相对均方根偏差<5%。
In this paper,a new technique of gas-gas rapid mixing is presented.The flow char- acteristics effected by impingement between jet and perforated plate is used to complete gas-gas rapid mixing.The parameters which affect the mixing quality have been studied by the authors,such as momenta ratio M,head loss coefficient of perforated plate ζ,the ratio of distance between nozzle exit and perforate plate to nozzle diameter H/D and the ratio of mixing length to reactor diameter L/D.Experiments are conducted in a cold model device of 300mm in diameter and the scale-up is verified in a cold model of 800mm in diameter.Experimental results show that,after mixing the relative root mean square deviation of concentrations across the cross section area of the equipment is less than 5 % at L/D=1,as long as proper parameters are selected.
