WF86——01微型反应装置主要用于:快速评选催化剂以及确定催化过程最佳条件;研究催化反应的动力学和机理以及影响催化活性的各种因素;研究催化剂的比金属表面,表面酸度及吸附系数等性质。由于本装置的微型反应器采用的是流化砂浴加热炉,这种加热炉的内温对壁温有较大的纯滞后。所以,采用通常的PID控制算法不容易得到满意的控制效果。本文将对该装置微机监控系统的功能及克服纯滞后影响的控制算法作详细介绍,并且阐述在微机上实现这种控制算法应该注意的问题。
WF86-01 micro-reactor is mainly used for: rapid selection of catalysts and to determine the optimum conditions for the catalytic process; study of catalytic reaction kinetics and mechanism and the various factors that affect the catalytic activity; study of the catalyst than the metal surface, surface acidity and adsorption Coefficients and other properties. Since the microreactor of this device uses a fluidized sand bath heating furnace, the internal temperature of such a heating furnace has a large net hysteresis of the wall temperature. Therefore, using the usual PID control algorithm is not easy to get satisfactory control effect. In this paper, the function of the computer monitoring system of the device and the control algorithm to overcome the effect of pure hysteresis are introduced in detail, and the problems that should be paid attention to when implementing such a control algorithm on a microcomputer are expounded.
