[0028] The drying belt 20 is a hollow structure. The inner cavity of the drying belt 20 is filled with a dehumidifier. Air holes are evenly arranged on the side walls of the drying belt 20. An air inlet pipe 2 is arranged at one end of the drying zone. The gas to be dried can enter the drying zone through the air inlet pipe 2, and the air passes through the straight section of the drying belt 20 and comes to the other end of the drying zone.

[0030] At the other end of the drying area, there is an exhaust duct 9 and a humidity sensor 13. The humidity sensor 13 can detect the humidity of the dried air to determine whether the air needs to be dehumidified again. The air that does not need to be dehumidified can be discharged through the exhaust duct 9.

The other end of the second branch pipe 3 extends into the inner cavity of the heating cylinder 22. An electric heating wire mesh cylinder 11 is fixedly connected in the inner cavity of the heating cylinder 22.

[0033] Exhaust holes are provided on both sides of the heating cylinder 22 and the cooling cylinder 23 close to the drying belt 20.

[0034] Exhaust pipes 14 are fixed on one side of both the first regeneration area and the second regeneration area. Through the exhaust pipes 14, the waste gas and water vapor in the first regeneration area and the second regeneration area can be discharged.

[0035] The electrical components involved in this application are all prior arts. Those skilled in the art understand their connection methods. Through those skilled in the art, all the electrical components in this application are connected to their adapted power supplies through wires, and a suitable controller is selected according to the actual situation to meet the control requirements. For the specific connection and control sequence, refer to the following description. The electrical components are electrically connected in the order of their sequential operations. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be made.

[0036] In summary: When the drying device for the wind power generation equipment is in use, the drying device is fixed at a suitable position of the wind power generation equipment. When the air inside the wind power generation equipment needs to be dried, the electric ball valves on the fourth connecting pipe 10 and the first connecting pipe 8 are both in the open state. The air inside the wind power generation equipment enters the drying area of the drying assembly under the action of the exhaust fan 7. The drying belt 20 in the drying area dehumidifies the incoming and outgoing air. The dehumidified air enters the side of the drying area away from the air inlet pipe 2. The humidity sensor 13 detects the dehumidified air. If the air humidity meets the requirements, the electric ball valve at the air inlet end of the first connecting pipe 8 connected to the exhaust pipe 9 of the drying area is in the open state, and the remaining electric ball valves are in the closed state. The air enters the inner cavity of the first connecting pipe 8 along the exhaust pipe 9, and the air in the inner cavity of the first connecting pipe 8 is discharged through the exhaust fan 7, realizing the dehumidification operation of the air inside the wind power generation equipment. If the humidity sensor 13 detects that the humidity of the dehumidified air is still relatively high and does not meet the requirements, the electric ball valve connected to the fourth connecting pipe 10 of the drying area is in the open state, and the electric ball valve adapted to the exhaust pipe 9 of the drying area is in the closed state. The dehumidified air can enter another drying assembly along the fourth connecting pipe 10, and the other drying assembly can continue to dehumidify the air until the air humidity meets the requirements; and during the dehumidification process, the drying belt 20 can be regenerated at high temperature, enabling the drying assembly to work continuously and ensuring the dehumidification effect.
