The invention discloses a steam recovery system and method for a blast furnace slag flushing filter tank, and belongs to the field of blast furnace metallurgy. The system comprises a filter tank, a water spraying pipe, a water supply part, nozzles and a steam collecting part, wherein the filter tank is used for blast furnace slag flushing; the water spraying pipe is used for supplying water to the nozzles, arranged along the periphery of the inner side wall of the filter tank and higher than the slag flushing height; the water supply part is used for introducing pressure water into the water spraying pipe; the nozzles are arranged on the water spraying pipe at intervals; when the nozzles spray water, a water curtain is sprayed obliquely upwards, a steam accommodating space is formed between the water curtain and the inner side wall of the filter tank, and the steam spaces formed by the water curtains sprayed by two adjacent nozzles are communicated, so that a steam channel is formed along each steam space aro
