The invention discloses an oil and gas recovery device for a gasoline station. The device comprises an underground oil tank, an oil tank truck, an oil and gas recovery tower and a nitrogen tank. An oil conveying pipe of the oil tank truck is connected with the underground oil tank, an oil and gas recovery pipe of the underground oil tank is connected with the oil tank truck, the oil and gas recovery tower is installed on the oil and gas recovery pipe, the oil tank truck and the underground oil tank are provided with pressure valves respectively, and the oil and gas recovery tower is filled with adsorbing agent. According to the oil and gas recovery device for the gasoline station, the small oil and gas recovery tower is built in the gasoline station, oil and gas are adsorbed through the adsorbing agent in the oil and gas recovery tower, decompression desorption or steam desorption is carried out after adsorption of the adsorbing agent is saturated, the transportation process of the saturated adsorbing agent is extremely small in risk, and safety is effectively increased.
