Xuye’s externally heated activated carbon making machine boasts stable system operation, a high degree of automation, and meets emission standards after combustion. The resulting biochar is of considerable value. The entire system features high carbonization efficiency, a long service life, high production efficiency, and a smokeless, environmentally friendly design. It can operate in a 24-hour continuous cycle, eliminating the shortcomings of traditional activated carbon production equipment<\/strong>, which suffer from low efficiency, high failure rates, high pollution, and high energy consumption.<\/p>\n\n\n\n

Environmental Protection Technology For environmentally friendly activated carbon kiln<\/a>, carbonization flue gas treatment is crucial. During the carbonization process, the flue gas generated in Xuye’s externally heated activated carbon production line is treated by a flue gas purification system, transforming it into a pure, combustible gas that is then passed into the bottom of the carbonization furnace for combustion, completing the carbonization process. This utilizes waste resources while eliminating flue gas pollution and damage to the environment.<\/p>\n\n\n\n

The material is continuously fed into the rotary kiln through a feed system and rotates within the furnace, achieving dynamic and uniform heating, avoiding the production bottlenecks associated with traditional batch processes.
At high temperatures (typically 800\u2013950\u00b0C), water vapor reacts with the carbon material (C + H\u2082O \u2192 CO + H\u2082), expanding the pore structure and forming activated carbon with a high specific surface area. Steam as an activation agent is environmentally friendly and controllable.<\/p>\n\n\n\n

Activated carbon making machine Process Flow<\/h2>\n\n\n\n

1.Feeding<\/strong>
Pretreated raw materials are continuously fed into the rotary kiln’s feed port via a specialized feeding device. This device, typically a screw feeder or other device, precisely controls the feed rate and amount, ensuring uniform distribution and a stable supply of material within the furnace.<\/p>\n\n\n\n

In the preheating zone, the material gradually heats up through heat exchange with the hot flue gases or heating elements within the furnace, preparing for the subsequent activation reaction.<\/p>\n\n\n\n

Heating and Rising Zone<\/p>\n\n\n\n

Temperature Range: 800-1050\u00b0C<\/p>\n\n\n\n

Steam Activation Zone<\/p>\n\n\n\n

Core Reaction Zone: The temperature is raised to a specified temperature, and superheated steam (pressure 0.1\u20130.4 MPa) is introduced.<\/p>\n\n\n\n

3.Activation Reaction<\/strong><\/p>\n\n\n\n

C + H\u2082O \u2192 CO + H\u2082 (endothermic reaction)
C + H\u2082O \u2192 CO + H\u2082 (endothermic reaction)
The steam selectively oxidizes the carbon, expanding the microporous structure, resulting in an iodine value of 1700 mg\/g and a specific surface area of 1500 m\u00b2\/g.<\/p>\n\n\n\n

Dynamic Contact: The rotary kiln rotates (1\u20135 rpm) to tumble the material, ensuring uniform and thorough steam contact.<\/p>\n\n\n\n

The activated material enters the cooling zone. Within this zone, cool air is introduced into the furnace or other cooling methods are used to rapidly cool the material, preventing overreaction or degradation of product performance.<\/p>\n\n\n\n

4.Cooling<\/strong>
Discharge
The activated carbon is discharged through a water-cooled screw discharger to prevent spontaneous combustion of the high-temperature material upon contact with air.<\/p>\n\n\n\n
