The invention discloses an environment-friendly asphalt storage system and belongs to the technical field of asphalt fume treatment. The environment-friendly asphalt storage system comprises a heavy oil tank and asphalt tanks. The heavy oil tank and the asphalt tanks are arranged in parallel connection. The environment-friendly asphalt storage system further comprises an asphalt fume cooling absorption device, an oil unloading device and a pump set. The upper ends of the heavy oil tank and the asphalt tanks are connected with the asphalt fume cooling absorption device through a first pipeline. Asphalt fume generated when the heavy oil tank and the asphalt tanks are heated enters the asphalt fume cooling absorption device, and a condenser in the asphalt fume cooling absorption device captures small granules in the fume and purifies the granules before the granules are discharged; one ends of the heavy oil tank and the asphalt tanks are connected with safety pressure devices correspondingly, and when pressure in the heavy oil tank and the asphalt tanks exceeds a set pressure value, the safety pressure devices control the pressure in the tanks to be released; and the other ends of the heavy oil tank and the asphalt tanks are connected with a second pipeline, and the second pipeline is connected with input equipment, the oil unloading device and the pump set. According to the environment-friendly asphalt storage system, an innocent treatment process is achieved, harmful ingredients are degraded, and fume emission is made to meet relevant standards.
