脱水仓在炉渣综合利用中的应用

Application of dewatering bin in slag utilization

针对脱水仓在运行中暴露出的设备结构不合理、腐蚀、磨损等问题,对其进行完善脱水仓结构和优化渣水系统设计方面的改进,包括钢结构支撑框架、平台和水池改为钢筋混凝土结构,拆除中间析水元件,修改析水管的布置,将底部析水元件气动排水阀改为手动阀,改脱渣水直接排放为闭式循环等。经改进后的脱水仓缩短了脱水时间、解决了磨损、节约了投资。介绍了尚在解决中的问题的实施方案,以期提高脱水仓运行的可靠性,在炉渣综合利用中创造出好的经济效益。

Dewatering bin, being extensively applied to slag utilization, has exposed problems in operation and resulted in inefficiency. These problems included irrational steel structure, corrosion and wearing, etc. Studies were made to improve the bin structure and optimize the design of slag sluicing system, such as changed the supporting frame, platform and clarifier with steel reinforced concrete structure, removed the decanting element in the process, modified the arrangement of the decanting tubes, changed the pneumatic discharge valve of the decanting element with manual valve, substitute direct discharge of slag sluicing with closed cycle, etc. The advanced dewatering bin reduces the decanting time, resolves wearing and saves investment. A scheme for the solution is implemented in order to raise the reliability of the dewatering bin and achieve better economic efficiency in slag utilization.
