Wood activated carbon making machine
A wood activated carbon kiln is a key piece of equipment in the production of wood activated carbon. Its core function is to transform wood and other raw materials into an activated carbon product with a rich microporous structure through a carbonization and activation process. Its operating principle is based on pyrolysis and gas activation. The specific process is as follows:
Carbonization Stage: Raw Material Pretreatment and Structural Transformation
High-temperature pyrolysis: Wood undergoes thermal decomposition in an oxygen-deficient environment (approximately 400-600°C), removing moisture, volatiles, and some organic matter, forming a carbon-rich skeleton. During this stage, the heating rate and holding time must be strictly controlled to prevent raw material combustion or structural collapse.
Preliminary Structural Formation: The solid product (called “carbonized material”) after carbonization possesses a preliminary pore structure, but the pores are large and have limited adsorption capacity, requiring further activation. Activation Stage: Micropore Construction and Performance Optimization
Physical Activation: Activating gases such as water vapor and carbon dioxide are introduced at high temperatures (800-1000°C) to undergo an oxidation reaction with the carbon in the carbonized material (e.g., C + H₂O → CO + H₂), expanding existing pores and creating new micropores, significantly increasing the specific surface area.
Chemical Activation (Optional): Some processes use chemicals such as phosphoric acid and zinc chloride to impregnate the raw materials. During the carbonization process, dehydration and corrosion create developed pores, making it suitable for the production of activated carbon with high adsorption properties.
Wood activated carbon making machine Key Technical
Temperature Control: 400-600°C for the carbonization stage and 800-1000°C for the activation stage, with an accuracy of ±5°C to ensure pore structure stability.
Atmosphere Control: Oxygen content monitoring and inert gas (nitrogen) supplementation are used to maintain a weakly oxidizing environment to avoid excessive ablation.
Raw Material Compatibility: A variety of wood-based materials, including sawdust, coconut shells, and fruit shells, can be processed. The moisture content of the raw materials should be controlled at 10%-15% to improve thermal efficiency.
Industry Applications and Market Value of Wood Activated Carbon Kilns
1.Environmental Water Treatment
Removes organic matter (such as phenols and dyes), heavy metal ions (Pb²⁺, Hg²⁺), and residual chlorine from water, meeting drinking water hygiene standards.
In municipal wastewater treatment plants, COD removal rates can reach 60%-80% in deep treatment processes.
2.Air Purification and Industrial Waste Gas Treatment
Adsorbs VOCs (volatile organic compounds) and odorous gases (such as hydrogen sulfide), and is used for exhaust gas treatment in paint shops and pharmaceutical factories.
Home air purifier filters reduce PM2.5 and formaldehyde concentrations through physical adsorption of activated carbon.
3.Food and Pharmaceutical Industries
Decolorization of food (such as sugar and fruit juice refining), removing pigments and odors.
Purification of pharmaceutical intermediates, high-purity activated carbon that meets GMP certification requirements.
