AGICO Activated Carbon Rotary Kiln
AGICO has introduced the internationally advanced rotary kiln manufacturing technology and developed and produced the activated carbon rotary kiln with excellent performance according to the properties of activated carbon. We also provide complete activated carbon production solutions.
AGICO activated carbon rotary kiln can be used for the carbonization and activation of materials and the regeneration process of waste activated carbon. The materials that can be processed include coconut shells, coal, wood, petroleum coke, resin, and other materials rich in carbon elements.
With the characteristics of high calcination efficiency, large production capacity, and high heat utilization rate, our Rotary Kiln not only has a good market reputation in the domestic market, but also sells well in the Philippines, Sri Lanka, India, Russia, and other countries, and is unanimously recognized and affirmed by users at home and abroad.
Outstanding Quality, High Reliability
The shell of the rotary kiln is made of high-quality carbon structural steel; The internal refractory material is the special refractory castable developed by our company through the analysis of various waste activated carbon components. It has the characteristics of good temperature resistance and thermal insulation, high acid and alkali corrosion resistance, and strong wear resistance.
Automatic Control, Easy Operation
The activated carbon rotary kiln adopts the PLC automatic control system, which can control all operation steps and switches through one computer terminal. The system greatly reduces the operation difficulty, simplifies the operation process and reduces the equipment operation cost.
Environmental Friendly Process Design
Both ends of the rotary kiln are sealed so that the waste gas will not be discharged, but will circulate inside the kiln to realize the recycling of internal heat. Each kiln is equipped with dust removal equipment and flue gas filtration equipment to minimize the emission of waste gas and dust and reduce environmental pollution.
Low Energy Consumption
Our advanced combustion technology can recover flue gas as energy and convert it into heat energy required for calcining in the kiln. This not only reduces exhaust gas emissions but also greatly improves the energy utilization rate and reduces a lot of energy costs for activated carbon producers.
Activated Carbon Kiln Processes
In the carbonization process of materials in the rotary kiln, the material is heated in a certain low-temperature range and under the condition of air isolation, so that the colloid in the material is orderly pyrolyzed and the fixed carbon with a cage structure is formed to the maximum. Because the carbonization temperature is low, the material will not produce graphitization, which is conducive to the subsequent activation reaction.
The carbonized materials enter the rotary kiln. Under the action of high temperature, some organic substances adsorbed on the materials boil, vaporize, and desorb, and some organic substances undergo decomposition reaction to generate small molecular hydrocarbons for desorption; Other compounds remaining in the micropores are cleaned under the action of water vapor or other activators, so that the material becomes activated carbon with adsorption performance.
Some volatile organic compounds adsorbed during the drying process are desorbed and converted into waste gas at high temperature and volatilized together with water vapor; During the carbonization process, most of the organic matter is carbonized and adsorbed in the pores of the activated carbon; During the activation process, the remaining organic compounds are pyrolyzed at higher temperatures, and the waste activated carbon is activated in the presence of a quantitative oxidant (water vapor or a small amount of oxygen). The activated carbon recovers the original pores and creates new pores to achieve the reactivation of the waste activated carbon.
