The invention discloses a purification device and method for continuous casting tundish molten steel, and belongs to the field of metallurgy. The purification device comprises a supporting base, wherein the supporting base is used for being placed above a baking hole or a preformed hole of a continuous casting tundish cover; a wave guide rod and an argon blowing pipe are installed on the supporting base and used for extending into molten steel of a tundish. The wave guide rod is sequentially connected with the transducer and the ultrasonic generator, the argon blowing pipe is connected with the argon control mechanism, and the lower end of the wave guide rod is located in the area above the outlet end of the argon blowing pipe. And a microporous ventilation element is arranged at the outlet end of the argon blowing pipe. According to the argon blowing device, the micropore ventilation element is arranged at the outlet of the argon blowing pipe, refining and dispersing of argon bubbles are preliminarily achiev
