| Abstract: |
| The vane filter is a very critical equipment in the decolorization section of the refining workshop, there are many process valves at the front end and follow-up of the equipment, there are many operation steps and time nodes to control the opening and closing of the valve, and the operation is complex and cumbersome. In order to simplify the tediousness of manual operation and provide technical reference for the control of more stand-alone systems, taking the vertical vane filter as an example, PLC and touch screen were used to build an automatic control system to control the stand-alone operation and switching control of the vane filter. The CPU of automatic control system adopted Siemens 1200 series S7-1214C DC/DC/Rly, HMI adopted Siemens lean series touch screen KTP1200, and Siemens TIA PORTAL V18 software was used for hardware configuration and programming, and the production of monitoring and control interface of host computer KTP1200. The design of the automatic control system includes separate control and switching control of the two sets of filters, and the time parameter of switching can be set according to different outputs. This system operates stably and reliably, and is an independent control system, which can be applied to production alone, also the system has Ethernet communication function, therefore can realize data exchange with other control systems. |
