As shown in fig. 2, the portions of the rotor 1 connected to the fresh air flow path 100, the return air flow path 200, and the regeneration air flow path 300 at any time form a dehumidification region 11, a return air region 12, and a regeneration region 13, respectively, that is, on the premise that the spatial positions of the fresh air flow path 100, the return air flow path 200, and the regeneration air flow path 300 remain unchanged, the spatial positions of the dehumidification region 11, the return air region 12, and the regeneration region 13 do not change with the rotation of the rotor 1, but all or part of the physical portions of the rotor 1 connected to the air flow structure are alternately switched among the three functional regions, i.e., the dehumidification region 11, the return air region 12, and the regeneration region 13. In the axial direction projection of the runner 1, the area of the dehumidification area 11 accounts for one half of the total area of the runner 1, and the areas of the return air area 12 and the regeneration area 13 respectively account for one quarter of the total area of the runner 1.

When the indoor return air is introduced to the return air zone 12 in the rotating wheel 1, on one hand, the silica gel adsorbent can adsorb VOCs gas in the return air to reduce the concentration of pollutants in the return air; on the other hand, the cold catalyst can decompose the VOCs gas into carbon dioxide and moisture, and the generated carbon dioxide and moisture can be adsorbed by the silica gel adsorbent, so that the concentration of pollutants in the air returned to the room is greatly reduced, and the purpose and the requirement of purifying the indoor air are achieved; clean air from the return air zone 12 is re-delivered to the indoor environment by the return air fan 4. The temperature of the regenerated air rises after passing through the external heat source 5, and when the high-temperature regenerated air is introduced to the regeneration zone 13 in the rotating wheel 1, the silica gel adsorbent desorbs the adsorbed moisture, carbon dioxide and VOCs due to the temperature rise, so that the regeneration of the silica gel adsorbent is realized; the regenerated air is regenerated into waste gas after the regeneration of the silica gel adsorbent is completed, and the waste gas is sent to the outdoor environment through a regeneration fan 6.
The invention also provides a use method of the composite air purification and dehumidification rotating wheel device, which comprises the following steps: the rotating wheel 1 is driven by a motor and a belt to rotate along the circumferential direction, the air flow structure is kept static, and all or part of the solid parts connected with the air flow structure on the rotating wheel 1 are alternately switched among the three functional areas, namely the dehumidification area 11, the return air area 12 and the regeneration area 13.
