| 摘 要： | 反应器内流体的流动行为和硫酸铵晶体粒子的悬浮情况,是设计工业生产硫酸铵反应器的关键.通过测定硫酸铵晶体的粒度分布(CSD),计算出硫酸铵晶体粒子恰好悬浮时的搅拌速率为100 r/min.针对一个为实际工业生产设计的连续结晶器,进行计算流体力学(CFD)模拟,得到其稳定的单相流场,并与200 r/min搅拌速率的流场进行对比.引入拉哥朗日离散相模型,进行两相流CFD模拟,验证不同粒度的硫酸铵晶体粒子在100 r/min搅拌速率下在连续结晶器内的悬浮效果.模拟结果表明设计的硫酸铵连续结晶器是合理的.

| Abstract: | Flow behavior of fluid and suspension of crystals of ammonium sulphate is the key to(designing) an industrial reactor in producing ammonium sulphate.A just suspending agitating speed,100(r/min,) was computed based on the crystal size distribution(CSD)of ammonium sulphate from experiments.Computational fluid dynamics(CFD)simulations were performed under 100 r/min for a developed industrial continuous crystallizer.The flow field of single phase was observed and compared with that under 200(r/min.) Then the La... |
