During the flowing process, the cold water can pass through the condensation member 92, and thus the stability of the surface of the condensation member 92 can be reduced. The high temperature and high humidity flue gas flows through the surface of the low temperature condensation member 92, and the water vapor in the flue gas is condensed to form water drops, which adhere to the surface of the condensation member 92.
In the condensation and dehydration process, the rotary driver 94 drives the rotary shaft 93 to rotate, and the condensation member 92 rotates at a high speed in the rotation process of the rotary shaft 93.

Specifically, the gaps 924 between the adjacent fins 923 penetrate not only the condensation pieces 92 in the up-down direction but also the condensation pieces 92 in the outer circumferential direction. In the rotation process of the condensation member 92, the condensation water droplets adhering to the surfaces of the fins 923 are discharged from the surface of the condensation member 92 in the circumferential direction, which is advantageous for the rotation and drainage of the condensation member 92.
