The activated carbon regeneration equipment produced by our factory adopts the thermal regeneration method, which is the most widely used and industrially mature activated carbon regeneration method. During the regeneration process of dehydrated activated carbon, according to the change of organic matter when heated to different temperatures, it is generally divided into three stages: drying, high-temperature carbonization and activation. In the drying stage, the volatile components on the activated carbon are mainly removed. In the high-temperature carbonization stage, a part of the organic matter adsorbed on the activated carbon is boiled, vaporized and desorbed, and a part of the organic matter undergoes a decomposition reaction to generate small molecule hydrocarbons. At this stage, the temperature will reach 800~900°C. The activation process is that activated carbon reacts with water vapor in an atmosphere of water vapor, burns off part of the carbon, reopens the micropores, and restores activity.
The exhaust gas generated during the regeneration of activated carbon is treated by secondary combustion, dry/semi-dry/wet washing, dust removal, etc., which can remove harmful components of organic matter, nitrogen oxides, acids, dioxins, and dust in the exhaust gas , to achieve exhaust emission standards.
