Working Principle of Activated Carbon Adsorption Adsorption Process
Activated carbon contains a highly porous structure with an extremely large internal surface area. Due to the presence of unsaturated molecular forces on the carbon surface, gas molecules are attracted and retained within the microporous structure.
When contaminated air passes through the activated carbon bed, pollutants are captured and concentrated on the surface of the activated carbon, while purified air is discharged into the atmosphere.
This physical adsorption process effectively separates pollutants from the gas stream and achieves high-efficiency air purification.

- Customer-specific environmental requirements
Activated Carbon Adsorption Unit Structure
The adsorption unit is the core component of the waste gas purification system.
The activated carbon modules are installed inside the equipment cabinet using a layered drawer-type structure, allowing quick replacement and convenient maintenance. Large inspection doors on both sides provide easy access while maintaining excellent sealing performance during operation.
Important Installation and Operation Guidelines
1. Inlet Gas Temperature Requirements
The inlet gas temperature should remain below 50°C.
If the waste gas temperature exceeds 50°C, a cooling system should be installed before the gas enters the adsorption chamber.
2. Dust Filtration Before Adsorption
For applications such as spray painting and coating processes that generate large amounts of dust or paint particles, pre-filtration equipment should be installed to remove particulate matter before adsorption.
3. High-Boiling Organic Solvents
When treating organic solvents with boiling points above 120°C, a steam-assisted desorption system is recommended to improve regeneration efficiency.
4. Steam Supply Options
If no steam source is available on-site, a compact electric steam generator can be supplied together with the activated carbon adsorption system.
