Abstract
A desiccant wheel is provided to be rotatable. Through the body of the wheel or a surface adsorbent, water vapor in humid air flow is adsorbed. By passing a high-temperature air flow through the wheel, the body or surface coating is regenerated with moisture removed. Along a cross-section radial, the wheel is divided into different areas. The body has three-dimensionally inter-connected pores. The pores can be of different types. The wheel is a complete concentric cylinder or a concentric cylinder comprising equal or unequal sectors. The equal or unequal sectors are separated with each other. The wheel can rotate at a fixed speed for continually repeating a process of adsorbing, transiting, and regenerating. Thereby, drying can be carried out without causing physical or chemical change to heat-sensitive material, which also improves drying efficiency, reduces size, lowers power consumption, and helps in carbon reduction for industry.
