The invention discloses a heavy oil storage tank VOCs safe recovery system and recovery process, belonging to the field of petrochemical environmental protection technology. It includes heavy oil storage tank 1, heavy oil storage tank 2, suction coolant window 1, suction coolant window 2 and suction fan, and the exhaust port of heavy oil storage tank 1 is connected through the first pipeline The suction fan is connected with a second pipeline in the middle of the first pipeline, and the second pipeline is used to send the cooled heavy oil to the underground oil tank; the suction fan is also connected with a heating furnace burner. The volatile gas of heavy oil extracted by the suction fan is passed into the burner of the heating furnace for incineration, and a breathing valve and a muffler at the suction port are respectively arranged on the first pipeline and the third pipeline. The invention can prevent the environment pollution caused by the volatilization of oil and gas, and ensure the safety and reliability of the recovery process, and hardly consume nitrogen during normal operation, and will not cause noise pollution.
