When the drying plate 10 is installed in the fan-shaped area, the telescopic positioning blocks 27 are inserted into the positioning holes.

[0036] The working process of the embodiment of the present invention is as follows: when in use, the air to be dehumidified is driven by the fan from the to-be-dehumidified area 6 through the drying plate 10 into the dehumidified area 7, and the moisture in the air is adsorbed by the desiccant in the drying plate 10, thereby obtaining a dry airflow with a relatively low relative humidity. At the same time, the rotating ring 1 rotates, and the regenerated air is heated and reversely passed through the drying plate 10 above, and the moisture in the desiccant is absorbed and taken away, thereby restoring the moisture absorption capacity of the desiccant. When the drying plate 10 needs to be replaced, the rotating ring 1 is rotated intermittently. During the interval, the uppermost drying plate 10 is replaced. Specifically, when the electromagnet 43 is energized, the two telescopic ring plates 23 are separated, the through groove 26 is exposed, and the new drying plate 10 falls onto the first V-shaped plate 4.
