Asphalt tank cleaning system

An asphalt tank cleaning system comprises a cleaning tank with a discharge outlet at the bottom, and is characterized by further comprising a catalytic cracking fractionating tower, a cooler and an oil slurry storage tank, an oil slurry outlet is formed at the bottom of the catalytic cracking fractionating tower and connected with the oil slurry storage tank through an output pipeline, and in addition, the oil slurry storage tank is connected with the cooler. A cooler is arranged on the output pipeline, and an output port of the oil slurry storage tank is connected with an input port of the cleaning tank. The oil slurry obtained by catalytic cracking and fractionation contains a large amount of aromatic hydrocarbon, and can be rapidly combined with asphalt by adding the oil slurry into the asphalt in a molten state, so that the asphalt components are improved, and the tank cleaning condition is achieved. The oil slurry is easily available as a raw material and low in operation cost. 一种沥青罐清罐系统，包括清洗罐，该清洗罐底部具有排放
