The Activated carbon adsorption is used for VOC organic waste gas purification treatment. The carbon bed is a dry waste gas purification equipment, which consists of a box and an activated carbon adsorption unit filled in the box. Activated carbon bed is an efficient, economical and practical organic waste gas treatment equipment, which plays the role of filtering and adsorbing odor; activated carbon adsorption is widely used in the treatment of VOC organic waste gas discharged from workshops, laboratories and other environments, such as benzene, alcohol, ketone, Ether, alkane, aldehyde, phenol, and other volatile gases are mainly used in chemical, machinery, printing, rubber, furniture, electromechanical, marine, automobile, petroleum and other industries.
How activated carbon adsorption works
During the adsorption process of activated carbon adsorption, due to the existence of unbalanced and unsaturated molecular attraction or chemical bond force on the solid surface of activated carbon, when the solid surface is in contact with gas, it can attract gas molecules to concentrate and keep them in the solid state. surface, this phenomenon is called adsorption. Using the adsorption capacity of the solid surface, the exhaust gas is brought into contact with the porous solid material on the large surface, and the pollutants in the exhaust gas are adsorbed on the solid surface to separate it from the gas mixture to achieve the purpose of purification. After the organic waste gas is removed by the air filter to remove the tiny suspended particles, it enters the adsorption box, and after being adsorbed by the activated carbon in the box, the harmful components are removed, and the purified gas that meets the emission standard is discharged to the outside through the fan.
Features of activated carbon adsorption
The activated carbon adsorption treats VOC organic waste gas, with mature technology, stable operation and good treatment effect. At the same time, according to the characteristics of the exhaust gas emitted in different production processes, such as the temperature of the exhaust gas, whether it contains oil mist, dust and other related parameters, pretreatment devices such as coolers and primary filters can be built or added at the inlet end of the activated carbon bed. It protects the activated carbon adsorption section and ensures that the activated carbon bed operates in a high-efficiency state. The activated carbon adsorption and adsorption efficiency is high, and the purification capacity meets the national environmental protection requirements.
High adsorption efficiency and strong capacity:
- The equipment has a compact structure, a small footprint, simple and convenient maintenance and management, and low operating costs;
- Able to treat a variety of mixed organic waste gas at the same time;
- Adopt automatic control operation design, easy and safe operation;
- Fully enclosed type, can be used indoors and outdoors
Activated carbon adsorption composition
The activated carbon adsorption has a simple structure, and there are two types of vertical structure and horizontal structure. The commonly used is the horizontal structure. The inlet and outlet are on both sides and on the same axis. The horizontal activated carbon bed contains the following components.
The body part of the adsorption box contains: an air inlet, an air outlet, and an activated carbon layer.
The adsorption layer part of the adsorption box contains: punching plate, adsorption material inlet and outlet, emergency channel;
