The invention discloses a petroleum transportation device with a drying function. The petroleum transportation device with the drying function comprises a driving cab, a petroleum storage chamber, a drying fan, an active carbon filter, an air inlet, an air outlet and an engine tail gas energy recycling device. The air inlet, the drying fan, the active carbon filter and the air outlet are designed in the petroleum storage chamber and connected in sequence. Moist air in the petroleum storage chamber enters through the air inlet and is delivered through the drying fan into the active carbon filter, so that water and impurities are removed, and obtained dry air is delivered out through the air outlet. An engine is used for providing driving power for the petroleum transportation device, and the engine tail gas energy recycling device is used for recycling energy of engine tail gas. The petroleum transportation device is simple in structure and practical, indoor air is dried through the active carbon filter so as to prevent petroleum from emulsification, the energy of engine waste gas can be reutilized, and energy saving and environment protection are achieved.
