摘要
河南龙宇煤化工有限公司正在运行的1套壳牌煤气化装置和正在安装的2台五环炉煤气化装置共产生煤泥220 t/d(设计排放量),该公司采用高压、高浓度、长距离、全封闭的管道输送方式,将煤泥输送到公用工程锅炉内进行二次焚烧,以实现大型煤气化装置生产资源的综合利用。简述了煤泥综合利用系统的工艺设备和工艺流程;论述了该系统的创新特点和技术优势;介绍了煤泥远距离管道输送以及配比燃烧的试验数据。结果表明,该系统投用后可处理气化装置废渣6万t/a,节约标煤0.9万t/a,直接经济效益约900万元/a。
One set of Shell coal Gasification plant has been operating and two sets of coal gasification plants with Wuhuan gasifier are installing in the Longyu Chemical Engineering Company Ltd.,from which 220 t/d（design quantity discharged）of coal sludge are formed totally,using high concentration,long distance and fully closed conveying mode by piping,this company will take the coal sludge to convey into the utility boiler for secondary incineration in order to realize the comprehensive utilization for production resource in the large-sized coal gasification plant.Author has simply described the process equipment and process flow for comprehensive utilization system;has discussed the innovation feature and the technology advantage of this system;has introduced the long distance conveyance of coal sludge by piping and the test data for combustion with a proper ratio of sludge.Result indicates that the 60 000 t/a of waste sludge can treated by this system after having been put into operation,9 000 t/a of standard coal is saved,direct economic benefit is about 9 million Yuan R.M.B.
