摘　　要：浸出器是浸出制油的重要设备,提高浸出器的性能不但能降低粕中残油,而且能够减轻后续高温脱溶或低温脱溶的负荷,进而节省蒸汽消耗。浸出器负压强制沥干装置是用不同的方式使沥干封闭油斗为负压,强制沥干湿粕物料中的低浓度混合油,达到湿粕含溶量进一步降低的目的。为了降低湿粕含溶量,提高企业经济效益,分别介绍了用液环真空泵、蒸汽真空泵、负压风机抽取浸出器沥干段负压装置的工艺,特点和适用范围,同时也阐述了不同类型的常用浸出器强制沥干封闭油斗的方式,最后对沥干效果和经济效益进行综合分析。通过浸出器负压强制沥干装置可以有效降低湿粕含溶量,在高温蒸脱时节省蒸汽消耗量进而为企业带来一定的经济效益。Extractor is an important equipment for oil leaching,improving the performance of the extractor not only reduces the residual oil in the meal,but also reduces the load of subsequent high-temperature desolventizing or low-temperature desolventizing,which saves steam consumption.Extractor negative pressure forced leaching device provides negative pressure to the leaching closed oil hopper using a different way to forcibly leach the low concentration miscella in wet meal materials,and achieve further reduction of solvent content in wet meal.In order to reduce the solvent content in wet meal and improve the economic efficiency of enterprise,the process,characteristics and scope of application of the negative pressure device of the extractor leaching section with liquid ring vacuum pump,steam vacuum pump and negative pressure fan were introduced respectively,and the forced negative pressure leaching closed oil hopper of different types of commonly used extractors were also described.Finally,a comprehensive analysis of the leaching effect and economic benefits were carried out.Through the negative pressure forced leaching device of extractor can effectively reduce the solvent content in wet meal,and save steam consumption in the high-temperature desolventizing and thus bring certain economic benefits for the enterprise.
