中文摘要：

在现有真空滤油设备的基础上，向真空分离室内中充入干燥空气，通过同步获得的实验数据对比充气前后相同的真空度下的脱水效率，实验表明充气后脱水率明显提高，从而提高了传统滤油设备的油水分离效果和效率；指出了在“真空洗涤”工艺中如何优化充气量和充气部位需进一步实验研究。

英文摘要：

On the basis of the existing vacuum filter, to add dry air to vacuum separation tank, and to compare dehydration efficiency before and after the ventilation under the same vacuum through the synchronous experimental data, the experiment shows that the dehydration rate is obviously improved after ventilation, thus oil purification effectiveness and efficiency from water of traditional oil filtering equipment is improved. Further experiment research is needed for how to optimize the ventilatory capacity and position in ＂Vacuum Cleaning＂ technology.
