The utility model discloses a sulfuric acid dilution waste heat recovery device which comprises a waste heat recovery mechanism, and the waste heat recovery mechanism comprises a bottom plate, a box body, a connecting box, a U-shaped round pipe, a heat conducting piece and a stirring rod. The top of the bottom plate is fixedly connected with a box body, the top of the bottom plate is fixedly connected with a connecting box with an opening in the left side, and the top of the connecting box communicates with and is fixedly provided with an electromagnetic valve. According to the utility model, hot gas with heat generated in the dilution process of sulfuric acid is discharged into the connecting box through the vertical pipe, and the gas filtered by the filter screen is discharged into the U-shaped connecting pipe through the U-shaped round pipe, so that the heat in the hot gas is transferred to the plurality of heat-conducting fins; the heat is recycled through the heat-conducting fins and is transferred to wa
