Vacuum tail gas processing device

The utility model relates to a vacuum tail gas processing device, include: gas recovery mechanism, incineration disposal mechanism and absorption emission. Gas recovery mechanism is suitable for and recycles the useful gas recovery in the tail gas, and includes and handle the subassembly through the consecutive vacuum buffer tank gentleness bulk absorption of pipeline. Incineration disposal mechanism is suitable for and carries out incineration disposal to the tail gas after the recovery processing subassembly is handled, and includes through consecutive liquid receiving tank, water sealed tank and the heat conduction oil furnace of pipeline, liquid receiving tank and gas absorb to handle and link to each other through main siphunculus way between the subassembly. Adsorb emission, be suitable for tail gas after handling the recovery processing subassembly to adsorb the back and discharge, and including an activated carbon adsorber, activated carbon adsorber and gas absorb to handle andlinks to each other thro
