摘要（英）：

The utility model discloses a secondary steam purification device during evaporation process of radioactive waste liquid. The secondary steam purification device comprises a purification tower, a steam inlet for introducing secondary steam in the purification tower, a steam outlet for the secondary steam to leave away from the interior of the purification tower, a spraying unit for spraying hot water, and a packing unit for reducing the radioactivity of the secondary steam, wherein the interior of the purification tower is hollow; the steam inlet is formed in the lower layer of the purification tower, and is communicated with the outlet of an evaporator; the steam outlet is formed in the upper layer of the purification tower; the spraying unit is arranged in the middle layer inside the purification tower; the packing unit is arranged in the purification tower, and is positioned between the spraying unit and the steam inlet. The secondary steam purification device can efficiently treat the secondary steam, and the treatment is relatively simple; the system device is relatively small in size, and the resistance for the secondary steam during the treatment is relatively low.
