What is the dehumidification principle of Rotary Dehumidifier and what is the essential difference from other dehumidification methods?
Publish Time: 2024-07-06
Rotary Dehumidifier is a highly efficient dehumidification device, and its dehumidification principle is based on the characteristics of adsorbent materials.
The core component of Rotary Dehumidifier is a continuously rotating wheel, which is usually made of special hygroscopic materials such as silica gel or molecular sieve. These hygroscopic materials have a large number of tiny pores that can absorb moisture in the air.
When humid air passes through the treatment area of the wheel, the moisture is absorbed by the hygroscopic material in the wheel. At the same time, the wheel continues to rotate and transfers the part that has absorbed moisture into the regeneration area. In the regeneration area, the moisture adsorbed in the hygroscopic material is discharged by heating or passing dry air, so that its hygroscopic capacity is restored, thereby realizing a continuous dehumidification process.
Compared with other dehumidification methods, Rotary Dehumidifier is essentially different. The traditional cooling dehumidification method is to achieve dehumidification by lowering the air temperature, so that the water vapor in the air reaches a saturated state and condenses into water droplets. However, this method is not effective in low temperature and low humidity environments and will lower the air temperature.
Desiccant dehumidification uses desiccant to directly absorb moisture from the air, but it usually requires frequent replacement of desiccant, which is cumbersome to operate.
The advantage of Rotary Dehumidifier is that it can still maintain efficient dehumidification capacity in low humidity environment, and can handle large air volume and provide stable low-humidity air. It is not limited by the air dew point temperature and can reduce the air humidity to a lower level. It is suitable for places with strict humidity requirements, such as electronics factories, pharmaceutical factories, museums, etc.
In addition, the operation of Rotary Dehumidifier is relatively stable and the maintenance cost is relatively low. As long as the rotor is regenerated and maintained regularly, its good dehumidification performance can be maintained.
In short, Rotary Dehumidifier has unique advantages in the field of dehumidification with its unique rotor structure and moisture absorption principle. It can meet the strict requirements of low humidity in many special environments, complement other dehumidification methods, and provide a variety of choices for users with different needs.
