Oil gas recovery system

The utility model relates to the technical field of oil gas recovery. The oil gas recovery system comprises a power supply, the power supply is connected with an MCU control chip, the MCU control chipis connected with an oil tank pressure sensor, an electromagnetic valve, a vacuum pump, a first condenser, a second condenser and a communication module, the communication module is connected with anantenna, and the antenna sends data to a network. According to the recovery device, oil gas generated in the oil tank can flow back into the oil tank after being recovered, and gas meeting the national atmospheric standard is discharged. According to the system, oil gas in the oil tank can be recycled according to the change of pressure in the oil tank, meanwhile, real-time change of air pressurein the oil tank can be known at a user terminal, and explosion caused by rising of the air pressure in the oil tank due to equipment faults in the recycling system is prevented. 本实用新型涉及油气回收技术领域，特别涉及一种油气回收系统，包括电源，所述电源连接MCU控制芯片，
