Detailed diagram of the working principle of the rotary dehumidifier

A rotary dehumidifier is also called a rotary dehumidifier or a rotary dehumidifying dryer. As the name suggests, it is a type of air dehumidification equipment with a rotary wheel. In short, the working principle of a rotary dehumidifier is to use its own rotary wheel to dehumidify. The dehumidification wheel or moisture absorption disk of the dehumidifier absorbs water vapor in the air by continuous rotation, and then uses high-temperature dry air to take away the moisture on the wheel, and then condenses the high-temperature humid air at room temperature to achieve the dehumidification effect. This working principle allows the rotary dehumidifier to dehumidify under any temperature conditions, and it cannot be affected by the ambient temperature, and naturally it is not restricted by region.

To explain the working principle of the rotary dehumidifier in detail, you must first understand the equipment structure of the rotary dehumidifier. There is a core component in the equipment structure of the rotary dehumidifier, called the dehumidification wheel. Adsorbents or desiccant are distributed on the dehumidification wheel, playing the core role of absorbing moisture. The selection of adsorbents must comprehensively consider the adsorption capacity and production costs. Usually, a synthetic porous hygroscopic material, synthetic silica gel, is selected. The adsorbed moisture is retained in the countless pores of the synthetic silica gel. As for the adsorption principle, interested friends please search it yourself.

According to the technical description of the above dehumidification working principle, the normal working steps of the rotary dehumidifier are:

1. The synthetic silica gel on the dehumidification wheel directly absorbs moisture from the air.
2. Then, in the regeneration zone of the rotary wheel, the water vapor adsorbed on the pores of the silica gel (adsorbent) is heated and vaporized.
3. The water vapor flows to the inlet of the regenerative heat exchanger, forming high-temperature and high-humidity air.
4. When it passes through the heat exchanger that has been cooled by the indoor cold and humid air, condensed water is formed and discharged due to the difference in dew point.

On the other hand, since there is no heat pump, the heating of the air is completely achieved by energy conversion, so the energy consumption is relatively high. Secondly, the moisture absorption efficiency and regeneration efficiency of the dehumidification rotary disk are limited, so the dehumidification capacity is much lower than that of the cooling dehumidifier. Generally, a cooling dehumidifier can easily achieve a dehumidification capacity of 200 liters/day or 30 liters/day, but the rotary dehumidifier of the same volume may only achieve a dehumidification capacity of 6 liters/day and the power consumption is several times that of a cooling dehumidifier with the same dehumidification capacity.
