航空煤油在使用过程中,要求洁净度高、无机械杂质等有害物质。探讨了旋流器用于煤油-杂质二相分离情况,对煤油-杂质在液-固旋流器内的分离过程进行了数值模拟,并研究了杂质粒径、入口处理量对分离效率的影响。计算结果表明:旋流器底流口阀门在适当时间内开启和关闭,可以避免被分离出的杂质再次污染液体和防止液体的流失;当杂质粒径大于一定值时,才能被有效地分离;旋流器的处理量存在着较优区间。这些结果可为旋流器在实际工程应用中的操作提供指导。(图7,参15)
Aviation kerosene in the use of the process, requiring cleanliness, no mechanical impurities and other harmful substances. The separation of kerosene and impurities was discussed. The separation process of kerosene and impurities in the liquid - solid cyclone was numerically simulated. The influence of impurity particle size and inlet capacity on the separation efficiency was also studied. The calculation results show that the hydrocyclone bottom-flow outlet valve can be opened and closed within the appropriate time to avoid re-contaminating the separated liquid and preventing liquid loss; when the impurity particle size is larger than a certain value, it can be effectively separated; There is a better range of flow capacity. These results provide guidance for the operation of the cyclone in practical engineering applications. (Figure 7, reference 15)
