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.

High-efficiency desiccant wheel

A method is provided to fabricate a green desiccant wheel. A green recycled adsorbent material of aluminum hydroxide and alumina is extracted and used as a base material to be added to a 3-dimensional (3D) network skeleton of a foam support. Through sintering, surface is hardened with the material adsorbed to megapores uniformly distributed. Thus, an adsorbent material of porous ceramic having pores on surface is made. The area contacting with moist air is increased. The moisture-adsorbing capacity is improved. At last, the whole procedure is integrated to develop a high-efficiency green desiccant wheel. Thus, the reusable materials are kept at innate grade or upgraded for recycling and regenerating. New materials and products can be further fabricated. The present invention helps solving environmental problem of wastes. Life cycle of resource is lengthened. A sample of recycling economy is innovated. Industrial efficiency is effectively enhanced.

Method of fabricating green desiccant wheel

Disclosed is a method for making a refractory material from aluminum residues of aluminum recycling. At first, the aluminum residues is mixed with adhesive solution so that the percentage by weight of the adhesive solution is 5 wt % to 10 wt %. The mixture is granulated into grains. The grains are filled in a mold, pressed and then removed from the mold so that the grains are turned into a green body. The green body is heated in a furnace at a range of temperature from 1100&#xb0; C. to 1400&#xb0; C. so that the grains are sintered and become a refractory material.
