Overview
The core component of a high-precision rotary dehumidifier is a honeycomb shaped rotary wheel, which is composed of a special ceramic fiber carrier and activated silica gel composite. The wheel is divided into two areas by the sealing device: the processing area (accounting for 270 sectors) and the regeneration area (accounting for 90 sectors).
Product Details
1、 Core working principle: Physical adsorption and regeneration cycle
The core component of a high-precision rotary dehumidifier is a honeycomb shaped rotary wheel, which is composed of a special ceramic fiber carrier and activated silica gel composite. The wheel is divided into two areas by the sealing device: the processing area (occupying 270 ° sector) and the regeneration area (occupying 90 ° sector).
Dehumidification process: When humid air passes through the processing area, water molecules are adsorbed by the silica gel in the impeller, and dry air is sent into the target space.
Regeneration process: The wheel slowly rotates to the regeneration area, and high-temperature air (usually 100-140 ℃) is blown in the opposite direction to evaporate the adsorbed moisture and discharge it outside, restoring the wheel's moisture absorption capacity.
Continuous cycle: The wheel rotates continuously at a speed of about 1/8 turn per minute, achieving seamless connection between dehumidification and regeneration, ensuring stable output of low humidity air.
2、 Core advantages: Efficiency, stability, and controllability
Ultra low dew point control
Through the principle of physical adsorption, it is easy to achieve a dew point temperature below -40 ℃, and even below -60 ℃ in enhanced mode, meeting the extremely demanding humidity requirements of scenarios such as lithium battery production and optical device manufacturing.
High Efficiency and Energy Saving
Compared to refrigerated dehumidifiers, rotary dehumidifiers can still operate efficiently in low-temperature environments and have lower energy consumption.
When using heat recovery technology, energy consumption can be further reduced, especially suitable for industrial scenarios that operate for long periods of time.
Intelligent Control and Stability
Equipped with a PLC control system, it can adjust the wheel speed and regeneration temperature in real time, and display key parameters such as dew point temperature and air volume.
The dual cooler structure ensures precise control of return air temperature and humidity, avoiding the impact of humidity fluctuations on production quality.
Adaptable
Suitable for industrial environments with a wide temperature range and low humidity requirements, such as plastic molding, pharmaceuticals, and food processing.
High temperature resistant ceramic material combined with silicone can withstand temperatures above 500 ℃ without the risk of deliquescence, ensuring long-term stable operation.
3、 Typical application scenarios of high-precision rotary dehumidifier
industrial production
Plastic molding: Control the moisture content of the material below 0.02% to avoid defects such as poor transparency, burrs, and bubbles.
Electronic manufacturing: prevent moisture from causing circuit board short circuits and component corrosion, and improve product yield.
Lithium battery production: Strictly control environmental humidity to avoid battery performance degradation or safety hazards.
Biomedicine
Maintain the humidity of the drug production environment at 45-65% to prevent soft capsules from sticking or clumping, and inhibit microbial growth.
Ensure that the drug storage room is dry and extend the shelf life of the drug efficacy.
food processing
Control workshop humidity to prevent candy dissolution and grain mold, and improve food quality and storage time.
Applied to cold storage, it inhibits bacterial growth and ensures food safety.
special environment
Offshore wind power: prevent converter module burnout caused by high humidity environment and reduce operation and maintenance costs.
Underground construction/civil defense engineering: Maintain a dry environment for a long time to prevent corrosion of steel structures.
Library and Archive Room: Reduce the moisture content of paper to prevent mold and spread of handwriting.
4、 Key points for installation and maintenance
Avoid airflow short circuit
Adequate distance should be maintained between the regeneration exhaust and the intake air, or anti short circuit measures should be taken (such as wind direction isolation plates).
The air duct should be made of heat-resistant and moisture-proof materials to ensure that the dew point of the treated air is lower than the ambient temperature and prevent condensation from damaging the rotor.
Configuration of heat recovery device
For scenarios with long-term operation or high dehumidification capacity, it is recommended to equip a heat recovery device to reduce energy consumption.
regular maintenance
Check the sealing performance of the impeller to prevent cross contamination between treated air and regenerated air.
Clean the filter to ensure smooth air circulation and maintain dehumidification efficiency.
5、 Technical positioning and industry value
The high-precision rotary dehumidifier achieves precise humidity control through physical adsorption and regeneration cycle technology, and its core value lies in:
Addressing the pain points of traditional dehumidification technology: Breaking through the performance limitations of refrigerated dehumidifiers in low-temperature environments, providing a more stable low humidity environment.
Improving production quality and efficiency: In humidity sensitive industries, it is directly related to product yield and equipment lifespan, reducing losses caused by humidity.
Promote industrial upgrading: provide basic environmental protection for high-precision manufacturing, biomedicine and other fields, and assist in technological breakthroughs in the industry.
High precision rotary dehumidifiers have become the mainstream choice in the industrial dehumidification field, especially suitable for scenarios with strict humidity control requirements and complex operating environments. Their technological maturity and reliability have been widely verified.
