【摘要】：以亲水玻璃微珠、改性疏水玻璃微珠、空气和水为实验介质,采用单因素方法,研究了固阀洗涤塔中颗粒粒径、入口颗粒浓度、两相流动参数、颗粒润湿性对粒径小于10μm颗粒的洗涤效率的影响。结果表明:粒径大于2μm的颗粒的洗涤效率均可达到90%以上;粒径大于0.5μm的颗粒,洗涤效率随粒径增加而升高;粒径小于0.1μm的颗粒,洗涤效率随粒径增加而下降;粒径为0.1~0.5μm的颗粒,洗涤效率随粒径的增加,先升高后降低。对于粒径小于2μm的颗粒,其洗涤效率随入口颗粒浓度、两相流动参数的增加,先升高后降低。颗粒润湿性对粒径小于2μm的颗粒,尤其是粒径为0.1~0.5μm的颗粒的洗涤效率影响显著,润湿性越好,洗涤效率越高,而对粒径大于2μm的颗粒的洗涤效率影响不大。
[Abstract]:Using hydrophilic glass beads, modified hydrophobic glass beads, air and water as experimental media, the particle size, inlet particle concentration and two-phase flow parameters of solid valve scrubber were studied by single factor method.Effect of particle wettability on washing efficiency of particle size less than 10 渭 m.The results showed that the washing efficiency of particles larger than 2 渭 m was above 90%, the washing efficiency of particles larger than 0.5 渭 m increased with the increase of particle size, the washing efficiency of particles with diameter less than 0.1 渭 m decreased with the increase of particle size.When the particle size is 0.1 渭 m, the washing efficiency increases firstly and then decreases with the increase of particle size.For particles with particle size less than 2 渭 m, the washing efficiency increases first and then decreases with the increase of inlet particle concentration and two-phase flow parameters.The wettability of particles has a significant effect on the washing efficiency of particles with particle size less than 2 渭 m, especially the particle size of 0.1 渭 m 0.5 渭 m. The better the wettability, the higher the washing efficiency, but not the washing efficiency of particles larger than 2 渭 m.
