Working principle of activated carbon adsorption tower
The activated carbon adsorption tower device mainly consists of an activated carbon layer and a support layer. Activated carbon has developed pores, a large specific surface area, and high adsorption capacity. It is precisely because of this characteristic of activated carbon that it is widely used in the deep treatment of water, such as domestic water supply, deep treatment of wastewater treatment in the later stage (purified water), etc.
Dust containing gas is powered by a fan and enters the tower at either positive or negative pressure. Due to the presence of unbalanced and unsaturated molecular attraction or chemical forces on the surface of activated carbon solids, when the solid surface comes into contact with the gas, it can attract gas molecules, causing them to concentrate and remain on the solid surface. The pollutants are then adsorbed, and the exhaust gas enters the equipment's dust removal system after passing through the filter, purifying the gas and achieving high altitude emission standards.
1. High adsorption efficiency, large adsorption capacity, and wide applicability
2. Easy maintenance without technical requirements
3. Large specific surface area and good selective adsorption
4. Activated carbon has the characteristics of a wide range of sources and low price
5. High adsorption efficiency and strong ability
6. Easy to operate and safe
After using activated carbon for a period of time, it adsorbs a large amount of adsorbate and gradually saturates, losing its working ability. In severe cases, it will penetrate the filter layer. Therefore, activated carbon should be regenerated or replaced.
