| 中文摘要: |
| 针对橡胶废水烟道喷雾蒸发技术，采用数值模拟方法研究液滴群蒸发特性的影响因素。结果表明：随着烟气流速的增大，液滴完全蒸发时间缩短，蒸发率提高，液滴完全蒸发距离呈先增大后减小的趋势；烟气温度越高和烟气水蒸气含量越小，液滴传质速率越快，液滴群蒸发特性越好；随着进料流量的增大，液滴完全蒸发时间缩短，液滴完全蒸发距离呈减小趋势，且有一段变化较平缓；进料温度对液滴群蒸发特性影响不明显。 |
| 英文摘要: |
| In view of the flue spray evaporation technology of rubber wastewater，the factors influencing the evaporation characteristics of the droplet were studied by numerical simulation methods. The results showed that as the flow rate of flue gas increased，the complete evaporation time of the droplet was shorted，
the evaporation rate increased，and the complete evaporation distance of the droplet increased at first and then decreased. The higher the flue gas temperature and the smaller the water vapor content in flue gas，the faster the mass transfer rate of droplet was，and the better the evaporation of the droplet was. With the increase of the feed flow，the complete evaporation time of the droplet was shortened，and the complete evaporation distance of the droplet decreased，which would have small change under certain feed flow range. The feed temperature had little effect on the evaporation characteristics of the droplet. |
