Research and Improvement of Control System for Slep Furnace Activated Carbon Production
This paper provides a basic introduction to the principle and working process of the Slep activated furnace.The Siemens S7-200 SMART series PLC is used to achieve logical and timing control of the ignition and unloading pro-cesses of the Slep activated furnace.Communication with the upper computer touch screen is established through Ethernet.Compared to the traditional control system for the Slep activated furnace,technical improvements are made to the tempera-ture and pressure acquisition modules.The previous method of using the S7-200 SMART analog input module for data ac-quisition is replaced by the use of a data acquisition card to collect temperature and pressure data,which is then transmit-ted to the upper computer touch screen via RS 485 bus for display.The ignition process is improved to ensure that it can continue even when there is a fault in the external detection elements.This system has the advantages of reliable control performance and good visibility.
