【摘要】：煤炭储配基地,即曹妃甸数字化煤炭储配基地项目(以下简称“本项目”或“该项目”)是以规划煤炭总流通量为2500万t/a,一期动态库存能力72万吨的大型煤炭储配基地,是曹妃甸港区的重点规划项目,建成后将成为全国的大流量、数字化、高精度的煤炭储配中心。综合自动化系统设计方案由“网络方案”、“生产过程控制系统”、“配煤专家系统”、“监控调度安全系统”、“机房系统”、“信息管理系统”等组成。以生产过程控制系统设计以及配煤系统设计为主。采用大型可编程控制器作为生产过程控制系统的控制核心,以主站与从站的通讯控制方式,单独或联动完成每一个相关工艺设备的集中受控任务。储煤系统控制范围为受煤皮带机开始,至堆料机止的全部受控设备;装船输煤系统控制范围为从取料机开始,至装船转运站止的全部受控设备。工程设计实现以17条皮带机等为主体的设备的储配输煤集中监测、过程控制,并提供接入圆形堆取料机、高压系统的接口;按照要求,在取料装船流程中通过配煤专家系统进行最优配煤,实现数字化精确配煤,生产出满足客户定制需求的商品动力煤,提高煤炭的附加值,使企业的效益最大化。
[Abstract]:The coal storage and distribution base, that is, the Caofeidian Digital Coal Storage and Distribution Base Project (hereinafter referred to as "this project" or "the project") is a large-scale coal storage and distribution base with a total coal circulation of 25 million tons and a dynamic storage capacity of seven hundred and twenty thousand tons in the first phase. Caofeidian Port area is a key planning project, the completion of the country will become a large flow, digital, high-precision coal storage and distribution center. The design scheme of integrated automation system is composed of "network scheme", "production process control system", "coal blending expert system", "monitoring and dispatching security system", "computer room system", "information management system" and so on. The design of production process control system and coal blending system are the main ones. The large-scale programmable controller is used as the control core of the production process control system. The central control task of each related process equipment is accomplished by the communication control mode between the master station and the slave station alone or in linkage. The control scope of the coal storage system is all controlled equipment from the start of the coal belt conveyor to the end of the stacker, and the control scope of the loading and transporting system is all controlled equipment from the beginning of the reclaimer to the end of the loading and transporting station. The engineering design realizes the centralized monitoring and process control of the storage, blending and transportation of the equipment with 17 belt machines as the main body, and provides the interface to the circular stacker and take-up machine and the high-pressure system. According to the requirement, the coal blending expert system is used to optimize the blending of coal in the process of taking and loading, to realize the digital and precise blending of coal, to produce commercial thermal coal to meet the custom demand of customers, to improve the added value of coal and to maximize the benefit of the enterprise.
