本文的研究目的是为 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。文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中间规模的实测值吻合较好。动态数据测试是在中间规模的空气脉冲式的混合澄清槽上进行的,工艺体系为 UO_2(NO_3)_2+/HNO_3+H_2O/TBP30%+OK。加在输入参数上的 PRBS 信号,由电子计算机的外给定来实现,输出参数由流线仪表连续检测。对测得的大量数据进行了解析,结果令人满意。
The purpose of this paper 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 dynamic model of extraction cascade proposed in this paper can predict the dynamic response data of two-phase components at all levels. Based on this model, the PRBS disturbance function was added to the input parameters of water flow and organic phase flow, and the dynamic mathematical simulation was carried out. The result is in good agreement with the measured data under the same conditions. The dynamic data test was carried out on an air-pulverized mixed clarification tank of intermediate scale with a process system of UO 2 (NO 3) 2 + / HNO 3 + H 2 O / TBP 30% + OK. The PRBS signal added to the input parameters is obtained from the external computer given, and the output parameters are continuously detected by the streamline meter. A large amount of data was analyzed and the results were satisfactory.
