    摘要
  • 摘要: 在内径为100mm的玻璃萃取塔内,采用甲基异丁基酮(MIBK)和二异丙醚(DIPE)两种煤化工废水处理常用的脱酚萃取剂,系统研究了新型导向格栅规整填料(DFG)的水力学特性和传质性能.结果表明:两种萃取体系的流体力学特性可以用改进型关联式较好地描述;导向格栅填料萃取塔的运行通量比国内常规萃取塔有大幅度的提高,试验范围内液泛通量最高达150m3/(m2·h);传质性能与国内常用规整填料相近,理论级当量高度在2.2~3.1m之间.导向格栅填料可以满足煤化工生产规模不断扩大对脱酚萃取塔的需求.
    Abstract: The hydraulic and mass transfer characteristics of a new type DFG oriented grid structured packing in a 100mm diameter extraction column were studied.MIBK (methyl isobutyl ketone) and DIPE (diisopropyl ether) were selected as extractants,which were widely used in solvent extraction for coal chemical industry wastewater phenols removal.Result indicated that the hydraulic of the two extraction systems can be well described by an improved correlation;compared to the traditional packing,the extraction column with DFG structured packing can greatly improve the operation loadings.Within the experiment range,the max flooding loading is as high as 150m3/（m2·h）.The mass transfer performance is similar to traditional structured packing,the height equivalent to theoretical stage （He） is between 2.2 and 3.1m.The DFG structured packing holds good integrated performances,which can meet the need of high throughput phenol removal extractors for the increasing large-scaled coal chemical industry.
