| 摘 要： | 将静电效应引入石灰浆烟气脱硫中,是烟气脱硫技术发展的新途径.而对石灰浆荷电雾化特性的研究则是石灰浆荷电雾化脱硫技术的关键.首次应用三维粒子动态分析仪（3D- PDA） 建立石灰浆荷电雾化试验装置,测定了石灰浆荷电雾化后的速度和粒径分布特性.对不同的荷电电压和石灰浆流量进行了测试,并运用相关的数据处理方法,得到了荷电石灰浆滴的三维速度与粒径的相关和统计特性.结果表明静电效应的引入能很好地提高石灰浆雾化质量,同时提高了浆滴的速度以及改善了粒径分布的均匀性,在荷电电压为5～10 kV时效果尤为明显.

| Abstract: | Introducing electrostatic effect is a new approach for the development of wet flue gas desulfurization technology.And the electrostatic spraying characteristics of lime slurry is the key of lime slurry electrostatic spraying desulfurization technology.With the application of 3D particle dynamic analyzer(3D-PDA),lime slurry electrostatic spraying test set was established to describe the distributing characteristics of velocity and particle size for the first time.The different charging voltages and lime slurry flow variables were measured.With the coherent data manipulation method,detailed measurement for a lime slurry electrostatic spraying nozzle has been completed in conjunction with velocity and particle size characteristics.The results indicate that the introducing of electrostatic effect can enhance lime slurry spraying quality and improve the distributing uniformity of lime slurry droplet velocity and particle size.The effect is obvious when charging voltage is 5 kV to 10 kV.lime slurry droplet;charging;PDA;average velocity of axes;average velocity of radial;average particle size |
