[0044] The desiccant may be, for example, lithium chloride, silica gel, metal-doped silica gel, molecular sieve or the like.

[0045] Dehumidification working principle: ① The first fan 11 drives the moist air flow from the first chamber 101 through the storage holes on the rotor 2 to flow into the second chamber 102, and the desiccant absorbs moisture in the air flow, thereby achieving dehumidification; ② During the dehumidification process, the drive motor drives the rotor 2 to rotate, and the storage holes rotate synchronously, so that more storage holes are in contact with the moist air flow, so that as much desiccant as possible can absorb moisture, thereby improving the moisture absorption uniformity and improving the dehumidification effect; ③ The dry air flow is discharged through the second connecting pipe 1021.

[0046] Drying working principle: ① The second fan 12 drives the regeneration air flow into the third chamber 103, and the heater 13 heats the regeneration air flow to form a hot air flow. The hot air flow flows into the fourth chamber 104 through the storage holes on the rotor 2 and takes away the moisture in the desiccant, thereby converting the desiccant into a dry state; ② During the drying process, the drive motor drives the rotor 2 to rotate, and the storage holes rotate synchronously, so that more storage holes are in contact with the hot air flow, so that as much desiccant as possible is in contact with the hot air flow, thereby improving the drying efficiency and uniformity; ③ The hot air carrying moisture is discharged through the fourth connecting pipe 1041.

[0047] Dehumidification usage steps: ① Close the third valve and the fourth valve, turn off the second fan 12 and the heater 13; ② Open the first valve and the second valve, connect the air flow to be dehumidified with the first connecting pipe 1011 through the pipeline, start the first fan 11, and achieve dehumidification.

[0048] Drying steps: ① Close the first valve and the second valve, and turn off the first fan 11; ② Connect the dry regeneration airflow (such as the regeneration airflow in the storage tank) to the third connecting pipe 1031 through a pipeline, and start the second fan 12 and the heater 13.

The first filter 14 and the second filter 15 are respectively plugged into the first chamber 101 and the third chamber 103 and are detachably connected to the shell 1, making the subsequent disassembly and maintenance of the filter more efficient and convenient. The present utility model adopts a split structure, splitting the first filter 14 into a first sub-filter 141 and a second sub-filter 142, thereby constructing a first strip hole and a second strip hole on both sides of the shell 1. Compared with the traditional technology of opening a 180° strip hole for integral filter plug-in, it has better structural strength.
