| 摘 要： | 对燃油在真空条件下的强化汽化过程开展实验研究。在可视化的真空容器内，测试燃料经喷嘴喷出后液滴破碎与汽化特性参数，得到不同喷油压力下的液滴粒径分布、汽液相发展形态变化、燃料汽化速度变化等规律。结果表明，真空下经喷嘴喷出后燃油的破碎和汽化是一个相互强化的过程，喷射压力越高，强化汽化的效果越显著。在喷射压力为5 MPa时，液滴粒径分布集中于5 μm范围内，在2 ms以内燃油汽化率达到平衡汽化率的85%，燃油快速接近汽液平衡。将强化汽化技术应用到常减压蒸馏工艺，可有效提高轻质油收率。

| Abstract: | Experimental study was carried out on the enhanced vaporization process of fuel under vacuum condition.Fuel was ejected from the nozzle in a visual vacuum vessel.The droplet crushing and vaporization characteristic parameters such as the liquid droplet size distribution, the gas-liquid phase morphological development, and the vaporization speed were obtained under different injection pressures.The experimental results show that the crushing of liquid droplets and the vaporization of fuel were mutually reinforced.At the injection pressure of 5 MPa, most of the droplet sizes are within the range of 5 μm, and within 2 ms the fuel nearly reaches equilibrium and reaches 85% of equilibrium vaporization capacity.When this enhanced vaporization technology is used in atmospheric and vacuum distillation processes, the yield of light oil will increase. |
