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:<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Production Requirements for Coal-Based Activated Carbon Equipment.<\/h2>\n\n\n\n

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.<\/p>\n\n\n\n

Product Specifications: The mainstream product is 2-4 mm granular activated carbon, with a specific surface area of 800-1200 m\u00b2\/g and a strength of \u226590%. 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.<\/p>\n\n\n\n

Wood activated carbon making machine Key Technical <\/h2>\n\n\n\n


Temperature Control<\/strong>: 400-600\u00b0C for the carbonization stage and 800-1000\u00b0C for the activation stage, with an accuracy of \u00b15\u00b0C to ensure pore structure stability.
Atmosphere Control<\/strong>: Oxygen content monitoring and inert gas (nitrogen) supplementation are used to maintain a weakly oxidizing environment to avoid excessive ablation.
Raw Material Compatibility<\/strong>: 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.<\/p>\n\n\n\n

Application Areas and Market Value<\/h2>\n\n\n\n


Core Applications in Water Treatment<\/strong>
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<\/strong>: Removes odor, taste, residual chlorine, and heavy metals (lead, mercury, etc.) from water, while reducing color.
Rainwater Purification<\/strong>: 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:<\/strong>
Air Purification:<\/strong> Adsorbs harmful gases such as formaldehyde and VOCs, and is used in air purifier filters.
Solvent Recovery<\/strong>: Recovers organic solvents such as benzene and ethanol in chemical production, reducing raw material consumption.
Desulfurization and Denitrification<\/strong>: Used as a catalyst carrier in power plant flue gas treatment to remove SO\u2082 and NOx.<\/p>\n\n\n\n
