摘要
依据液体二维不均匀流动、二维涡流扩散模型 ,建立了在给定汽液平衡关系式条件下 ,提出了一个不均匀漏液对板上液体浓度分布影响的数学模型 ,在此基础上 ,采用差分法对该模型进行求解。讨论了在不同的参数 (包括 )下不均匀漏液对板效率的影响 ,以图表的形式给出。结果表明 ,漏液的不均布确实会对板效率产生重大影响 。
A mathematical model for liquid concentration on tray and a formula on tray efficiency were proposed considering of mal-distributed weeping and given the formula of gas-liquid balance, under the condition of the two dimension non-uniform flow and two dimension eddy diffusivity .Solving the model with calculus of differences. the effects of mal-distributed weeping on tray efficiency were discussed with table here. The results showed that mal-distributed weeping had heavy effects on distillation tray efficiency .we should solve the problem of tray efficiency with the hypothesis of mal-distributed weeping.
