Beschreibung
Zusammenfassung:	The invention discloses an energy-saving and environment-friendly vacuum device applied to petrochemical engineering and a mixed arene separating system. A drive shaft and a driven shaft which are mutually parallel are longitudinally arranged in a shell of the vacuum device, the lower ends of the drive shaft and the driven shaft are provided with a drive gear and a driven gear respectively, and the drive gear and the driven gear have the same tooth number and are mutually meshed; and the interior of the shell is divided into a plurality of levels of pump cavity from the top to bottom, and thedrive shaft and the driven shaft in each level of pump cavity are provided with a pair of rotor pairs used for compressing pumped gas. With the vacuum device, the mixed arene separating system can effectively realize gas-liquid separation of arene extraction, has low energy consumption and waste, and has no pollution.
