The dehumidification section of a rotary dehumidifier operates mainly on the principles of adsorption and regeneration. Its working process is roughly as follows:

1. Adsorption SectionAfter pretreatment (such as filtration and heating), the air enters the wheel section of the dehumidifier. The wheel is filled with hygroscopic materials (such as silica gel or molecular sieves) that have strong hydrophilicity and can adsorb moisture from the air. As air flows through the wheel, moisture is captured by the hygroscopic material, thereby reducing the air humidity.
2. Regeneration SectionWhen the wheel rotates to the regeneration section, the hygroscopic material needs to release the adsorbed moisture. At this point, the wheel achieves regeneration by heating or by introducing low-humidity air. The heated air passes through the wheel, causing the moisture in the hygroscopic material to evaporate and be carried away, forming a moist exhaust stream.
3. Cycle ProcessThe rotation of the wheel causes the adsorption and regeneration processes to alternate continuously, thereby achieving a sustained dehumidification effect. The wheel design usually maintains a good balance between high-efficiency dehumidification and energy consumption.

Owing to its high efficiency and energy-saving characteristics, the rotary dehumidifier is widely used in industrial, commercial, and household settings.

除湿段运行原理

除湿段是转轮除湿机的核心，湿空气在除湿区被吸湿材料捕获水分，转轮旋转至再生区后经热风脱附，水分随再生排风排出。合理设计除湿区与再生区比例，可在目标露点与再生能耗间取得平衡。

再生节能

再生加热可采用排风余热或热泵，降低再生能耗，提升系统整体能效与运行经济性。
