NOVELTY - The utility model claims a heat exchange mechanism for flue gas recovery tower, comprising a graphene heat exchange pipe (1) vertically distributed in the flue gas recovery tower, the graphene heat exchange pipe is provided with a rotational flow plate (2), the bottom of the graphene heat exchange pipe is connected with a flue gas conveying pipeline (3); the top of the graphene heat exchange pipe is connected with a medicine spraying pipeline (4). The beneficial effect of the utility model is that the flue gas is operated from bottom to top; the natural air is operated from outside to inside; the non-contact heat exchange condensation is carried out; the flue gas channel is provided with a rotational flow plate and a medicine spraying pipeline; the smoke gas channel realizes collision and adhesion of water vapor, absorbing and condensing, and flowing into the water collecting area along the channel pipe wall under the action of gravity; the dust removing efficiency can reach more than 99 %, so that the smoke is deeply purified, and the white fog disappears.
