Importance of adsorption rotors in rotary dehumidifiers
2024.05.20
The design of the rotor in a rotor dehumidifier is critical to its high adsorption efficiency. The rotor typically consists of a porous matrix made of a mechanically supported material and coated with a hygroscopic agent. This construction allows humid air to enter at one end of the rotor, and as the rotor rotates, moisture is continuously transferred from the air to the hygroscopic agent. This process is known as the hygroscopic phase. The rotor then enters a regeneration phase whereby the moisture on the hygroscopic agent is evaporated through exposure to hot air, thus restoring the moisture absorption capacity of the rotor.
The efficiency of the rotor is affected by a number of factors, including the speed of rotation, the nature of the hygroscopic agent, the heat and mass transfer characteristics, and the size of the rotor. For example, metal foams have been selected as the base material for rotors because of their light weight, high compressive strength, low specific weight, high stiffness and high energy absorption capacity. In addition, the design of the runner takes into account how to maximise its surface area to improve moisture absorption efficiency. For example, honeycomb air channels can increase the surface area of a given surface to improve moisture absorption efficiency.
The "Fung Hong" rotor dehumidifier uses a world-class patented high-efficiency rotor, which is based on a patented technology: together with an inorganic binder glass fibres are processed into a honeycomb shape, under high temperature combustion all organic substances are transferred, and then the rotor of the honeycomb matrix is fused by polymerisation and a special silica gel (metallosilicate), so that it not only has good heat resistance, but also Has good heat resistance, but also can be applied in any degree conditions. It has strong dehumidifying ability, no dehumidifier loss, non-toxicity, non-corrosive, and ensures safe and stable operation for a long time. Because the rotor increased hydrophilic groups and micropores to absorb more water, according to the air conditions, drying capacity than other silica gel rotor increased by 10-20%.
Overall, the choice of rotor is crucial, not only to consider the contact area of the rotor with the air, to improve the distribution uniformity of the hygroscopic agent, but also to consider the effect of the regeneration cycle to ensure that the rotor can be in the whole operating cycle to maintain a high degree of hygroscopic efficiency.
