    Flow Behavior through Venturi Rod Banks in WFGD Spray Tower

      摘要
    • 摘要: 在冷模实验观察测定基础上,采用Euler-Euler多相流模型对湿法脱硫(WFGD)喷淋塔内文丘里棒层进行数值模拟,得到不同操作条件下压降和持液量的变化规律。结果表明,棒层区域阻力系数λ分别与Reg-0.58和Rel0.65成线性关系(Reg,Rel分别为气相雷诺数和液相雷诺数),持液量H分别与Reg0.52和Rel1.06成线性关系。加入棒层可显著提高持液量,降低液气比(液气体积比为Vl/Vg),此举有利于压降减小。拟合结果对于工程应用有指导意义。

       

      Abstract: Based on the observation and measurement in cold-modelling test, the flow behavior through Venturi rod banks in WFGD spray tower was studied numerically with Euler-Euler multiphase model. The characteristics of pressure drop and liquid holdup under operating conditions were simulated. The results show that resistance coefficient (λ) is proportional to Reg-0. 58 and Rel0. 65 and the liquid holdup (H) is proportional to Reg0. 52 and Rel1. 06. Introducing rod banks is beneficial to the increase in liquid holdup and the decrease in V1/Vg. The correlation for pressure drop and liquid holdup is instructive for engineering application.
