PLC In Shenhua Wuhai Energy Company Coal Preparati On Plant Control System Application And Research

This papers to Shenhua wuhai energy company flat Groove selected coal preparation plant of process features and requirements for cases, to selected coal equipment between of contact and effect selected coal effect of technology parameter for research object, aimed at design a heavy between selected coal set monitoring and technology parameter automatically measurement and control system, achieved on heavy media selected coal process in the technology parameter of online detection, and monitored and the stability of control, while guarantee heavy media selected coal process of points selected effect and improve production management level, to improve productivity, reduced workers intensity, Economic efficiency has improved significantly. This use of advanced hardware and software, automation instruments and modern Web technologies, pinggou coal preparation plant of the company’s existing production processes and integrated analysis of plant, mainly around real responses, equipment control, technical process of suspension parameters such as density automatic adjustment of a few. The paper’s main findings:1. Under heavy medium coal preparation technology process framework, with industrial control computer, PLC, sensors and actuators for hardware platform, using SIMATIC Step7software, SIMATIC WinCC configuration software control program and configuration screen the development, completion of monitoring and control system.2.Using Profibus bus technology to realize the information exchange between the hardware equipment.3. Through a variety of automated monitoring and control instrumentation and communications technology, realizes to the suspension liquid density, liquid level and a swirler entrance pressure automatic control.4. On the adaptive control, fuzzy control, neural network, artificial intelligence and other modern control algorithms, and actively explore a fast and accurate detection and stable control of drum level qualified medium more reasonable control method.5. By choosing the appropriate online material level detection system, industrial television system and production scheduling system, to meet the coal washery monitoring,...
