| 中文摘要: |
| 探讨了用机械搅拌法制备柴油－甲醇－水复合乳化燃料的机理，认为乳化过程是在强制对流作用下的强制混合过程，是主体对流扩散和涡流扩散两种扩散机理综合作用的结果，但混合速度取决于涡流扩散的速度。对采用SG－2乳化剂在机械搅拌乳化装置上配置柴油－甲醇－水复合乳化液的工艺进行了试验研究，结果表明，搅拌槽的挡板，搅拌器的叶轮转速，搅拌时间，乳化剂含量和甲醇中的含水量等参数对乳化液的稳定性有重要的影响。 |
| 英文摘要: |
| The mechanism of emulsification, which is suitable for preparing diesel oil-methanol- water composite emulsified fuels by mechanical agitating, was analyzed in this paper. The process of emulsification is considered as a forced mixing operation brought about by forced convection and results from combined mass diffusion by convection and by swirling. However, the general mixing velocity depends on the diffusion velocity by swirling. In this work, the technique for preparing diesel oil-methanol-water emulsified fuels using the SG-2 emulsifying agent by mechanical agitating was investigated experimentally. The experimental results showed that the stability of the emulsified fuels prepared was influenced significantly by the configuration of baffles in the agitation device, the rotational speed for agitating, the agitation time, the emulphor content, and the water content in methanol. |
