| Abstract: | The principle of control of pressure difference between hydrogen main pipe and chlorine main pipe in the electrolytic cell is analyzed,i.e.a double closed-loop ratio control system.Common faults are introduced:(1)the difference between hydrogen pressure and chlorine pressure fluctuates during normal production;(2)after two electrolyzers trip at the same time,the pressure difference is low,causing interlock,then one single line stops;(3)when an element cell is separated from the system,the pressure difference is difficult to control.The corresponding control measures are given. |
| Keywords: | electrolyzer hydrogen and chlorine differential pressure PID regulating valve |
