Disclosed is an integrated exhaust gas recovery device. An oil gas recovery header pipe, a pressurized air-blower unit, a gas-liquid separation device, an adsorption tower, a vacuum pump, a heat exchanger, a cyclic refrigerating unit, a recovery pot, a hydraulic pump unit and a process pipeline are integrated into one body and are installed inside a special-purpose frame structure. Instrument andequipment installation and debugging are carried out before the device provided by the invention is out of the factory, thus realizing overall design, overall installation and overall debugging. After equipment arrives at the loading and unloading site, the device can be directly used only after connecting anchor bolts, the technical pipeline, power supply line and communication circuits and simple debugging, thus saving onsite design and onsite construction amount, shortening project duration, avoiding onsite welding, raising onsite security and simultaneously improving reliability of a handling control system.
