Activated carbon flash dryer

Activated carbon is a specially treated carbon. The organic raw material is heated under air-tight conditions to reduce non-carbon components (carbonization) and then reacts with gas, the surface is eroded, and a microporous structure is produced (activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point erosion, so the surface of activated carbon has countless tiny pores. The surface area of ​​each gram of activated carbon is 500~1500㎡, and almost all applications of activated carbon are based on this feature of activated carbon.
Activated carbon is widely used. As the main solid adsorbent, it is an important part in chemical, pharmaceutical, and environmental aspects. It is used to adsorb substances with high boiling points and critical temperatures and organic matter with large molecular weight. The application in air purification, water treatment and other fields also shows a trend of increasing application. Special high-grade carbon such as high specific surface area carbon, high benzene carbon, and fiber carbon have penetrated aerospace, electronics, communications, energy, bioengineering, and life sciences.

Activated carbon flash dryer Equipment Description:
Activated carbon flash dryer uses wind as a wet and heat carrier and a fan as a power source to achieve mass and heat exchange in the drying process, so that the moisture in the material undergoes a phase change and the material and moisture are separated.
Drying generally uses the natural wind. After passing through the air filter, the natural wind is blown into the steam heat exchanger, coal-fired, oil-fired or gas-fired hot air furnace by the fan to be heated. The heated hot air is then distributed into a uniform cyclone with a certain flow rate and direction through the hot air distributor of the flash main engine. The cyclone contacts and collides with the wet material added by the spiral feeder, and a series of physical changes such as mass and heat exchange and separation begin, so that the material is separated from the moisture contained.

Activated carbon flash dryer Equipment advantages:
1. A variety of feeding devices are available, and the feeding is continuous and stable without bridging.
2. A special cooling device is set at the bottom of the dryer to avoid the deterioration of the material in the high-temperature area at the bottom.
3. Special air pressure sealing devices and bearing cooling devices effectively extend the service life of the transmission part.
4. The special air distribution device reduces the equipment resistance and makes the wind speed in the tower tend to be balanced.
5. The drying chamber is equipped with a classification ring and a swirl plate, and the material fineness and final moisture are adjustable and controllable.
6. The circumferential air velocity in the drying chamber is high, and the material residence time is short, which effectively prevents the material from sticking to the wall and the deterioration of heat-sensitive materials.
