摘要
建立带附加供料的准理想级联的数学模型,提供求解该类级联方程的数值方法,并得到方程的解析解。推导带附加供料的准理想级联中相对产品流、相对贫料流、级联中总物质流量及产品流和贫料流中组分丰度的解析表达式。用带附加流的准理想级联模型对回收铀浓缩进行级联计算,其中天然铀作主供料,回收铀作附加供料。
A mathematical model is established for the quasi-ideal cascade with an additional feed flow.A numerical calculation method to solve the cascade equation was presented and analytical solution of the cascade equation was obtained.Analytical expressions are given for calculating the relative product and waste flows,the total substance flow,and the component concentrations in the product and waste flows.Calculations for the enrichment of recycled uranium are carried out by using the model of quasi-ideal cascade,in which the natural uranium is supplied as a base feed flow while the recycled is supplied as an additional one.
