摘　　要：河北省矾山磷矿是1983年化工部化工矿山规划设计院设计的国家重点大型磷矿,1996年建成投产,自2008年开始不断进行设备更新和生产工艺优化。磷精矿脱水段用陶瓷过滤机取代真空过滤机,取消了热风炉干燥设备系统,进一步优化陶瓷过滤机反冲运行系统和陶瓷滤板清洗作业操作新技术,使得陶瓷过滤机的运行效率明显提高,大幅度地降低了磷精矿脱水生产的运行成本。实现每年可节约脱水段生产费用约639万元,每年减少不合格磷精矿产品产出7500t而增加的经济效益约375万元。取消燃煤进行烘干,极大降低碳排放及粉尘排放,产生了良好的环境效益和社会效益。Fanshan phosphate mine in Hebei province is a national key large-scale phosphate mine designed by Chemical Industry Mine Planning and Design Institute of Ministry of Chemical Industry in 1983.It was built and put into operation in 1996.Since 2008,the equipment has been continuously renewed and the production process has been optimized,in the dewatering section of phosphate concentrate,the vacuum filter was replaced by the ceramic filter,the drying equipment system of the hot blast stove is cancelled,and the backwash operation system of the ceramic filter and the new operation technology of the ceramic filter plate cleaning were further optimized,the operation efficiency of the ceramic filter is obviously improved,and the operation cost of the dewatering production of phosphate concentrate is greatly reduced.About 6.39 million yuan could be saved in the annual production cost of dewatering section,and 7500 tons of unqualified phosphate concentrate could be reduced every year,resulting in growing of economic benefit of about 3.75 million yuan.Canceling coal-burning for drying greatly reduced carbon emissions and dust emissions,resulting in good environmental and social benefits.
