The utility model discloses a novel modularized blowdown system for a sulfuric acid waste heat boiler, which comprises a continuous blowdown flash tank, a periodic blowdown flash tank and a blowdown cooling pool, and two sides of the continuous blowdown flash tank are respectively connected with a liquid level meter and a sewage discharge control valve through pipelines. The liquid level meter and the sewage discharge control valve are in interlocking control, a pipeline where the sewage discharge control valve is located enables the continuous blowdown flash tank and the periodic blowdown flash tank to be communicated, the bottom end of the continuous blowdown flash tank is further connected with a through pipe, a manual valve is installed on the through pipe, and the manual valve is connected with the sewage discharge control valve. A pipeline at the bottom of the periodic blowdown flash tank is communicated with the end part of the through pipe; compared with an original blowdown system, the occupied area
