本文所述研究工作的目的是为Purex流程1A萃取槽(混合澄清槽)的控制系统设计提供控制对象的动态特性。报告中提出的萃取级联动态机理模型,可以预报各级两相组分的动态响应数据。以此模型为基础,在水相流量和有机相流量的输入参数上加PRBS干扰函数,进行动态数学模拟,其结果与相同条件下的实测值吻合较好。 在中间规模的空气脉冲式的混合澄清槽上进行动态测试,工艺体系为UO_2(NO_3)_2+HNO_3+H_2O/TBP30％+OK。由电子计算机的外给定来实现加在输入参数上的PRBS信号,由流线仪表连续检测输出参数。对测得的大量数据进行分析,结果令人满意。
The goal of the research described in this article is to design the control system for the Purex Process 1A extraction tank (mixed-clarification tank) to provide the dynamic properties of the controlled object. The proposed extraction cascade dynamic mechanism model predicts the dynamic response data of two-phase components at all levels. Based on this model, the PRBS interference function was added to the input parameters of water flow and organic flow, and the dynamic mathematical simulation was carried out. The result is in good agreement with the measured data under the same conditions. Dynamic tests were carried out on a mid-sized, air-pulverized mixer-settler with a process system of UO 2 (NO 3) 2 + HNO 3 + H 2 O / TBP 30% + OK. External computer given by the external to add the input parameters on the PRBS signal by the streamline meter continuous detection of output parameters. Analysis of a large number of measured data, the results are satisfactory.
