The role of activated carbon adsorption tower

Activated carbon adsorption tower has become more and more widely used in the industrial development of the past few years. It has handled the discharge of various wastes very well, is environmentally friendly and clean, and has a good development trend in the society. Let me introduce it to everyone. The role of activated carbon adsorption tower.


In industrial production, organic solvents are widely used in cleaning, decontamination, dilution, extraction, etc., as intermediates for chemical synthesis, and as raw materials for paint and coatings.


Gas that can be removed

In addition to benzene, phenols, alcohols, ethers, tinctures and other organic waste gas, as well as hydrogen chloride gas, hydrogen fluoride gas, ammonia, sulfuric acid mist, chromic acid mist, hydrogen cyanide gas, alkali vapor, hydrogen sulfide gas and other acid and Alkaline gas.


Reduce organic solvents:

1. Organic solvents produce various poisons, generally irritating the skin and mucous membranes, causing special damage to the nervous system, hematopoietic system, lungs, heart, liver and kidneys and other organs, causing sudden death from chemical sources, and having carcinogenic effects.

2. Use the adsorption performance of activated carbon for harmless treatment, like spills in the paint spray process, mainly used to dilute paint thinners, generally composed of ethyl acetate, butyl acetate, benzene, toluene, xylene, acetone, ethanol, Butanol is prepared according to a certain weight percentage.


What waste gas does the activated carbon adsorption tower treat?


Activated carbon adsorption tower has the advantages of wide application, high adsorption efficiency, simultaneous treatment of multiple mixed waste gas, convenient maintenance, etc. Activated carbon can remove harmful gases such as formaldehyde, benzene, TVOC, and disinfection and deodorization. Activated carbon adsorption towers are now widely used It is used in the production of electronic components, battery (battery) production, metallurgy, chemical industry, medicine, pickling operations, laboratory exhaust, painting, food, brewing and other waste gas treatment, which is suitable for the purification of spray paint waste gas treatment.

Working principle of activated carbon tower

Activated carbon is a kind of black powdery, granular or pellet-shaped amorphous and porous carbon. The main component is charcoal, but also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It also has a fine structure like graphite, but the crystal grains are small and the layers are stacked irregularly. It has a large surface area (500~1000㎡/g).


It has strong adsorption capacity and can adsorb gas, liquid or colloidal solid on its surface.


The adsorption of gas and liquid can be close to the quality of activated carbon itself. Activated carbon adsorption tower and activated carbon are used together, which has a very good effect on industrial organic waste gas treatment.


The adsorption effect of the activated carbon adsorption tower is selective, and non-polar substances are easier to adsorb than polar substances. In the same series of substances, the higher the boiling point, the easier it is to be adsorbed. The higher the pressure, the lower the temperature, the higher the concentration, and the greater the adsorption capacity. On the contrary, decompression and temperature increase are beneficial to the desorption of gas.
