AI Technical Summary
In existing rotary dehumidifier systems, there is severe cross-interference of heat between the treatment zone and the regeneration zone, which leads to decreased dehumidification efficiency, increased regeneration energy consumption, and shortened rotor life.
The system adopts a layered composite rotor structure, including an outer, middle and inner rotor. The pore size of the adsorption material in each layer gradually decreases. Fresh air passes through the three rotors in sequence for three-stage series treatment. The rotor is divided into a treatment zone and a regeneration zone by a partition plate, and a heat pump system is used to provide regenerated hot air.
It achieves three-stage gradient dehumidification, reduces airflow resistance, avoids heat cross-interference, improves dehumidification efficiency, reduces regeneration energy consumption, and extends the service life of the impeller.
