As an efficient waste gas treatment equipment,activated carbon adsorption tower is widely used in various fields
to remove harmful gases and odor produced in the production process.
The equipment through the strong adsorption capacity of activated carbon,the harmful components in the exhaust
gas adsorbed on the surface of activated carbon,so as to achieve waste gas purification and emission standards.
The industrial activated carbon adsorption tower not only can effectively reduce the concentration of pollutants
in the waste gas,but also has the advantages of simple structure, convenient operation and low maintenance cost.
1、How it works
The principle of waste gas treatment in industrial activated carbon adsorption tower is mainly based on
the adsorption performance of activated carbon.
Activated carbon is a kind of porous carbon material,which has very high specific surface area and abundant
pore structure,and these pore structures provide a lot of adsorption sites for gas molecules.
When the waste gas passes through the activated carbon adsorption tower,the pollutants such as organic matter,
inorganic matter, odor and so on in the waste gas are attracted by the adsorption site on the surface of
the activated carbon,and adhere firmly to the surface of the activated carbon, so as to achieve the goal
of purifying waste gas.
The adsorption performance of activated carbon is influenced by its physical properties,such as specific surface area,
pore structure, and chemical property, such as surface functional groups.
The larger the specific surface area, the more developed the pore structure, the stronger the adsorption capacity.
At the same time, the functional groups on the surface of activated carbon can also react with some pollutant molecules
to further enhance the adsorption effect.
2、Technology
The waste gas treatment process of industrial activated carbon adsorption tower
usually includes the following steps:
2-1、Waste Gas Collection
First of all,through the gas cover, pipes and other equipment will be produced in the production process
of waste gas collection,to avoid direct emissions to the atmosphere.
2-2、Pre-treatment
Pre-treatment is usually required before the waste gas enters the activated carbon adsorption tower.
The main aim of pre-treatment is to remove the large particles, oil mist and other impurities in the waste gas,so as
to reduce the burden of the activated carbon adsorption tower and improve the adsorption efficiency.
Pre-treatment equipment includes cyclone dust collector, bag dust collector, wet dust collector, etc...
2-3、Adsorption Purification
After the pre-treatment of waste gas into the activated carbon adsorption tower,and the tower of activated
carbon in full contact.
The pollutant molecules in the exhaust gas are attracted by the adsorption sites on the surface of the activated
carbon and adhere to the surface of the activated carbon,thus realizing the purification of the exhaust gas.
Activated carbon adsorption tower usually adopts multi-layer structure to improve adsorption efficiency
and treatment capacity.
2-4、Desorption and regeneration
With the adsorption process, the surface of activated carbon adsorption sites will be gradually occupied,
adsorption capacity gradually reduced.
In order to restore the adsorption capacity of activated carbon, it is necessary to carry out desorption
and regeneration treatment.
Desorption is usually carried out by means of heating, decompression or purging,which will be adsorbed
on the surface of the pollutants molecules adsorbed down.
The regenerated activated carbon can be reused in the adsorption process to achieve recycling.
2-5、Emission and monitoring
The exhaust gas after adsorption and purification is discharged into the atmosphere through the discharge pipe.
In order to ensure that the emissions meet environmental standards,it is usually necessary to monitor the discharge outlets.
The monitoring content includes such parameters as pollutant concentration in exhaust gas, emission rate and so on.
