The invention relates to the technical field of blast furnace smelting, and particularly discloses a blast furnace ash removal system and a blast furnace ash removal method. The blast furnace ash removal system comprises a level gage, a gravity dust removal bin, a bin pump, a gas delivering mechanism, an ash conveying pipe, an ash storage bin and a filter. The level gage is arranged in the gravity dust removal bin. The bottom of the gravity dust removal bin communicates with a feeding port of the bin pump. A discharging port of the bin pump communicates with a feeding port of the ash storage bin through the ash conveying pipe. The filter is arranged at an opening of the ash storage bin. A discharging port of the gas delivering mechanism communicates with a discharging port of the bin pump. The gas delivering mechanism can discharge compressed gas. An ash discharging valve is arranged at a feeding port of the gravity dust removal bin. A conveying valve is arranged between a discharging port of the gas deliveri
