摘要/Abstract

摘要： 本文提出一种新型连续制备甲醇柴油乳化柴油的新方法，分散相甲醇粒径的大小及分布对甲醇柴油乳化燃料的燃烧和使用有重要的影响。采用显微摄像技术及算数统计的方法表征了甲醇柴油乳化燃料中分散相甲醇的平均粒径。研究结果表明：甲醇柴油乳化燃料分散相甲醇的Sauter平均粒径随超重力因子、乳化剂含量等的增加而减少，随甲醇含量的增加而增大。分散相甲醇的平均粒径可以通过改变操作参数控制12-40μm。采用Matlab语言应用程序对平均粒径与超重力因子、乳化剂含量、甲醇含量等因素进行了关联，实验值与关联值吻合较好。

Abstract: A new continuous process for preparing methanol-diesel oil emulsified fuel with an Impinging Stream-Rotating Packed Bed is proposed. The droplet size of dispersed phase (methanol) of the emulsified fuel has a significant effect on the combustion of methanol-diesel oil emulsified fuel. In this paper, the continuous phase is diesel oil and the dispersed phase is methanol. The Sauter mean diameter of the dispersed phase of methanol- diesel oil emulsified fuel was characterized with microphotography and arithmetic method. The experimental result showed that the Sauter mean diameter of dispersed phase decreased with the augment of the high gravity factor, liquid flow rate and emulsifier dosage, were inversely proportional to the methanol content. The Sauter mean diameter of the dispersed phase can be controlled and adjusted in the range of 12-40 μm through the change of operation conditions. The correlative expressions of the Sauter mean diameter of emulsified fuel were obtained and the calculated values agreed with the experimental values well.
