摘　　要：在冶金反应釜或者反应槽工作的过程中,经常会出现化学物质在反应的过程中由于温度和压力产生溢出物的状况,人工看管不利的情况下容易造成事故和有毒物质的释放;反应速度的快慢直接影响到了资源的利用率,对工厂的产能造成影响。传统的自动控制加人工看管的方式,仍然没使安全性和经济效益得到提高。本文中采用一种光电化学反应控制器,利用PLC采用PID调节根据现场化学反应产生气体的速度、浓度对光线明暗的不同影响来调节反应槽或者反应釜中的气动隔膜阀的开度,从而降低或提高化学反应的速度和浓度。达到完全自动控制的状态。既提高了冶金反应过程的效益也提高了工人工作的安全性。In the process of metallurgical reaction kettle or reaction tank,chemical substances often overflow due to temperature and pressure in the process of reaction,which is easy to cause accidents and release of toxic substances in case of adverse manual care;the speed of reaction directly affects the utilization rate of resources and the production capacity of the factory.The traditional way of automatic control and manual supervision has not improved the safety and economic benefits.In this paper,a kind of photoelectric chemical reaction controller is used,and PID is used to adjust the opening of the pneumatic diaphragm valve in the reaction tank or reactor according to the different influence of the speed and concentration of the gas produced by the chemical reaction on the light,so as to reduce or improve the speed and concentration of the chemical reaction.To achieve the state of full automatic control.It not only improves the benefit of metallurgical reaction process,but also improves the safety of workers.
