Problems solved by technology
[0004] Under the condition of turbulent flow (turbulent flow), a large number of eddies on the surface of the steam are mixed with the pumped gas to entrain the gas, so a large part of the material is taken away by the steam, which wastes energy and produces a large amount of polluted water. Send sewage treatment plant for sewage treatment, which increases the operating cost of the enterprise

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.
Description
technical field [0001] The invention relates to a petroleum refining production equipment, in particular to a vacuum device and a mixed aromatic hydrocarbon separation system applied to petrochemical energy saving and environmental protection. Background technique [0002] In the process of petroleum refining and chemical production, the aromatics extraction process device in the prior art adopts a steam jet pump vacuum extraction process. The pumping mechanism of the steam jet pump is based on the high-speed moving steam flow mixed with the pumped gas for energy exchange to achieve pumping. [0003] There are at least the following disadvantages in the above-mentioned prior art: [0004] Under the condition of turbulent flow (turbulent flow), a large number of eddies on the surface of the steam are mixed with the pumped gas to entrain the gas, so a large part of the material is taken away by the steam, which wastes energy and produces a large amount of polluted water.
