The Characteristics of Columnar Activated Carbon

1. High adsorption performance: columnar activated carbon has a large specific surface area and pore volume, which can effectively adsorb and remove harmful gases, odors and polluting substances in the air, such as formaldehyde, benzene, ammonia, etc.

2. Good mechanical strength: cylindrical activated carbon adopts special manufacturing process, has high mechanical strength and wear resistance, is not easy to break and powder, and can be used stably for a long time.

3. Easy replacement and maintenance: Cylindrical activated carbon is usually made of a fixed length and diameter, can be easily installed in the equipment or system, replacement and maintenance is also relatively simple.

4. Long life: the life of cylindrical activated carbon is long, and it can be periodically replaced or regenerated according to the actual use and adsorption saturation to extend the service life. 5. Wide range of applications: cylindrical activated carbon is widely used in air purification, water treatment, industrial waste gas treatment, food processing, pharmaceutical manufacturing and other fields, which can effectively improve environmental quality and protect human health.

Columnar Activated Carbon Manufacturing Process

The manufacturing process of columnar activated carbon mainly includes raw material selection, carbonization, activation, grinding and forming steps. 

1. Raw material selection: Choosing the right raw material is the key to manufacturing high-quality columnar activated carbon. Commonly used raw materials include lignin, coal and fruit shells, etc., according to different application needs to choose the appropriate raw materials.

2. Carbonization: The raw material is carbonized, and the organic matter in the raw material is converted into carbon through high temperature heating, and the preliminary activated carbon is formed.

3. Activation: The carbonized raw materials are activated, and the commonly used activators are water vapor, carbon dioxide, etc. During the activation process, the activator reacts with the carbon to form more pore structure and improve the specific surface area and adsorption performance of the activated carbon.

4. Grinding: Grinding the activated carbon to make the particle size uniform, and remove impurities and bad particles.

5. Molding: The ground activated carbon is molded, the common molding methods are pressing molding and extrusion molding. The molded activated carbon has a fixed length and diameter for easy installation and replacement.

The Application Field of Columnar Activated Carbon

1. Air purification: columnar activated carbon is widely used in air purification equipment, such as air purifiers, air conditioning filters, etc. It can absorb and remove harmful gases, odors and fine particles from the air, providing a fresh indoor air environment.

2. Water treatment: columnar activated carbon can be used in the field of water treatment, such as water purifiers, faucet filters, etc. It can remove residual chlorine, organic matter, heavy metal ions, etc., and provide safe and clean drinking water. 

3. Industrial waste gas treatment: columnar activated carbon can be used in industrial waste gas treatment systems to adsorb and remove harmful gases and polluting substances in waste gas, purify waste gas emissions, and protect the environment and human health.

4. Food processing: columnar activated carbon can be used in food processing to remove odors, pigments and harmful substances in food and improve the quality and safety of food.

5. Pharmaceutical manufacturing: columnar activated carbon can be used in the pharmaceutical manufacturing process to remove impurities and harmful substances in drugs and improve the purity and quality of drugs.
