摘　　要：针对现行粗硒生产传统加热干燥存在的缺点,研制开发了一种用于富硒渣深度干燥的多层旋转式微波生产试验装置.微波频率为2 450 MHz、微波功率为0~54 kW连续可调.该微波生产试验装置设有手动-自动两种控制方式,可根据生产实际进行灵活切换;自动控制系统根据红外测温仪检测并反馈到的信号,进行PID运算后,通过双向可控硅实现对磁控管的功率调控.生产试验表明该装置满足了富硒渣生产工艺的要求,提高了粗硒的直收率,并降低了生产成本.In order to overcome the drawbacks of conventional dry technology used in the production of selenium,the multilayer rotary microwave device used in depth drying selenium rich slag is designed in this paper.The microwave frequency is 2450MHz,and the microwave power is 0~54kW which is continuously adjustable.This device equipped with two control modes,namely,manual and automatic modes,can switch flexibly according to actual production.The detected signal and feedback by the infrared radiation thermometer are then carried out the PID operation.The power of magnetrons is controlled by the bidirectional triode thyristor.It is proven that the automatic control system can satisfy the production process requirements of selenium rich slag.
