The invention provides a flue gas humidity control method based on a Nafion tube. The flue gas humidity control method comprises the steps that the initial moisture content of flue gas to be treated is obtained, and the flue gas to be treated is introduced into the Nafion tube; acquiring a first rotating speed of a Nafion tube power pump based on the initial moisture content of the to-be-treated flue gas, and adjusting the running rotating speed of the Nafion tube power pump to the first rotating speed; after the Nafion tube power pump operates at the first rotating speed for a first time interval, the first humidity of the flue gas output by the Nafion tube is obtained; the rotating speed of a Nafion tube power pump is adjusted through a PID algorithm, so that the deviation between the humidity of the flue gas output by the Nafion tube and the first humidity is smaller than or equal to a threshold value. According to the flue gas humidity control method based on the Nafion tube, the problem that the humidity
