| Ion-exchange membrane electrolysis technology with its low energy consumption, good quality, can achieve a higher degree of automation become hydrochloride produces chlorine by electrolysis of advanced production technology. Currently in development at home and abroad has entered the fast track. Electrolytic device power consumption of a large proportion of the total chemical, the success of control systems can improve the quality of products, maintain a stable operation of devices, reduced effort, and more on energy-saving emission reduction play a role in promoting. This article describes ion-exchange membrane technology electrolysis technology, and base on this technology foundationand according to current DCS control technology define the control stragegy for control points as voltage, and current, and temperature, and pressure, and flow, and liquid bit, and PH value, parameter of monitoring and control made has programme, apart from used General of single circuit of PID control outside, also used has program, and series level control, and ratio control, and other special control, control thought, while take has some necessary of alarm and joint lock. Quote third party software for better monitoring and improving controller performance. Due to this is electrolysis plant, the rectifier is critical control and descripe the control technology. Define the CL2 compressor control stragety and detail control description for pressure and anti pressure control. |
