What is activated carbon?
A kind of porous amorphous carbon in powder or granular form with strong adsorption capacity. It is obtained by carbonizing solid carbonaceous materials (such as coal, wood, hard nut shells, fruit cores, resins, etc.) at 600-900℃ in the absence of air, and then oxidizing and activating them with air, carbon dioxide, water vapor or a mixture of the three at 400-900℃.
Uses of activated carbon
Activated carbon is an adsorbent with a wide range of uses. Activated carbon with small pore size can be used for gas separation, recovery of solvent vapor, refrigerator deodorant, and adsorbent in gas masks. Activated carbon with large pore size can be used for decolorization to remove coloring substances in solutions, such as decolorization of sugar, glucose, alcohol, oil, medicine, water purification, etc.; it can also be used as a catalyst.
Working principle:
After the wet material is put into the dryer from one end, the material is evenly distributed and dispersed in the dryer under the turning of the evenly distributed scrapers in the inner drum, and is fully in contact with the co-current (countercurrent) hot air, which accelerates the drying heat transfer and transmits the driving force. During the drying process, the material can be controlled to move to the star-shaped discharge valve in another section of the dryer to discharge the finished product under the action of the inclined scrapers and hot air flow.
Applicable materials:
◎ Drying of large particles and heavy materials in the chemical, mining, metallurgical and other industries, such as: mining, blast furnace slag, coal, metal powder, phosphate fertilizer, ammonium sulfate.
◎ Drying of powdered and granular materials with special requirements, such as: HP foaming agent, wine lees, light calcium carbonate, activated clay, magnetic powder, graphite, and drug residue.
◎ Materials that require low temperature drying and large-scale continuous drying.
Performance characteristics:
◎ The rotary drum dryer has a high degree of mechanization and a large production capacity.
◎ The resistance of the fluid passing through the cylinder is small and the functional consumption is low.
◎ Strong adaptability to material characteristics.
◎ Stable operation, low operating costs, and good uniformity of product drying.
