Coal based granular activated carbon rotary kiln
Coal-based granular activated carbon kilns are specialized thermal equipment for producing coal-based granular activated carbon. Through two core processes, carbonization and activation, they transform raw materials such as anthracite into a porous adsorbent material. Their operating principle is as follows:
Carbonization: Coal (such as high-quality anthracite) is heated in an oxygen-free environment, causing pyrolysis to form a carbon structure and remove volatiles, creating initial pores.
Activation: Activators such as steam and carbon dioxide are introduced under high temperature and pressure to further expand pores, increase specific surface area, and enhance adsorption performance.
Forming and Post-Processing: The carbonized and activated material is crushed, screened (typically to a particle size of 2-4 mm), washed, and dried to produce the finished granular activated carbon.
Production Requirements for Coal-Based Activated Carbon Equipment.
Raw Material Compatibility: Anthracite is the primary raw material, but lignite, bituminous coal, and other types can also be processed. Raw materials are selected based on carbon content and density.
Product Specifications: The mainstream product is 2-4 mm granular activated carbon, with a specific surface area of 800-1200 m²/g and a strength of ≥90%. Environmental protection requirements: It must be equipped with tail gas treatment equipment to reduce sulfide and nitrogen oxide emissions and comply with clean production standards.
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.
Application Areas and Market Value
Core Applications in Water Treatment
Products produced in coal-based granular activated carbon kilns are ideal for water treatment due to their well-developed pore structure and high adsorption efficiency:
Municipal Water Supply: Removes odor, taste, residual chlorine, and heavy metals (lead, mercury, etc.) from water, while reducing color.
Rainwater Purification: Used in rainwater collection systems to adsorb organic compounds, pesticides, and suspended solids, improving water quality and taste.
Industrial Wastewater Treatment: Treats printing and dyeing and chemical wastewater, removing COD, BOD, and recalcitrant organic matter.
Other Key Applications:
Air Purification: Adsorbs harmful gases such as formaldehyde and VOCs, and is used in air purifier filters.
Solvent Recovery: Recovers organic solvents such as benzene and ethanol in chemical production, reducing raw material consumption.
Desulfurization and Denitrification: Used as a catalyst carrier in power plant flue gas treatment to remove SO₂ and NOx.
