Overview
A large rotary dehumidifier is an efficient air dehumidification device based on the principle of physical adsorption, which achieves continuous adsorption and desorption of air moisture through a rotating honeycomb wheel. Its core function is to physically adsorb and expel moisture from humid air, thereby providing a stable, low humidity air environment.
Product Details
1、 Core definition and functional positioning
A large rotary dehumidifier is an efficient air dehumidification device based on the principle of physical adsorption, which achieves continuous adsorption and desorption of air moisture through a rotating honeycomb wheel. Its core function is to physically adsorb and expel moisture from humid air, thereby providing a stable, low humidity air environment. Compared with traditional cooling dehumidifiers, it breaks through the limitations of low-temperature environments and can achieve deep dehumidification under low-temperature and low humidity conditions. The dew point temperature can be as low as -70 ℃, meeting the high-precision humidity control requirements.
2、 Working principle: Dual zone cyclic adsorption regeneration
structural composition
Wheel: Composed of high-temperature resistant ceramic fiber carrier and high-efficiency moisture absorbing medium (such as silicone or molecular sieve), it has a honeycomb structure, large surface area, and high moisture absorption efficiency.
Sealing system: Divide the rotor into a processing area (occupying 270 ° sector) and a regeneration area (occupying 90 ° sector) to ensure independent air flow paths.
Auxiliary components: including regeneration heater, fan, heat exchanger and control system, jointly completing air circulation and energy recovery.
operating process
Dehumidification stage: Wet air is sucked into the treatment area, and the moisture absorbing medium in the impeller adsorbs water molecules. Dry air is then sent into the target space through a fan.
Regeneration stage: The wheel slowly rotates to the regeneration area, and high-temperature air (100-140 ℃) is blown in the opposite direction, causing the adsorbed moisture to evaporate and be discharged outdoors with the humid air.
Continuous cycle: The wheel rotates at a speed of 8-12 revolutions per hour to achieve continuous alternation between dehumidification and regeneration, ensuring stable operation of the equipment.
IIILarge rotary dehumidifierTechnical advantage: Breaking through the limitations of traditional dehumidification
Ultra low humidity control capability
It can achieve harsh dry environments with relative humidity below 1%, far exceeding the dew point limit of 10-15 ℃ for cooling dehumidifiers, and is suitable for precision manufacturing scenarios that are sensitive to humidity.
Wide temperature adaptability
It can still operate efficiently in low temperature environments (such as below 5 ℃), while cooling dehumidifiers are prone to frost formation and failure under these conditions.
Energy saving and heat recovery design
Some models adopt a dual cooler structure to recover waste heat from the regeneration process and reduce energy consumption; When used in conjunction with the freezing method, the total power consumption can be saved by 20-30%.
Stable, reliable, and low maintenance
The physical adsorption process has no chemical residues, and the moisture absorbing medium has a long service life without frequent replacement; The device has a compact structure, easy installation, and is suitable for long-term continuous operation.
