Tank Body: Usually made of high-quality carbon steel, stainless steel, or fiberglass reinforced plastic (FRP) and other materials, it has good corrosion resistance and airtightness, ensuring the stable operation of the equipment under different environmental conditions. The shape and size of the tank body are determined according to the actual treatment requirements, and it generally comes in shapes such as square and circular.
Activated Carbon Layer: This is the core part of the activated carbon adsorption tank, consisting of a large number of activated carbon particles or activated carbon fibers and other materials. Activated carbon has a huge specific surface area and a rich microporous structure, which can provide strong adsorption capacity and effectively adsorb various organic waste gases and some inorganic waste gases.
Gas Flow Distribution Device: Installed inside the tank body, its function is to make the waste gas entering the adsorption tank pass through the activated carbon layer evenly, ensuring full contact between the activated carbon and the waste gas and improving the adsorption efficiency. Common gas flow distribution devices include perforated plates, gratings, etc.
Gas Inlet and Outlet: The gas inlet is used to connect to the waste gas emission source, allowing the waste gas to enter the activated carbon adsorption tank for treatment; the gas outlet is connected to the subsequent exhaust pipeline or purification system, discharging the clean gas treated by adsorption.
Inspection Door: Set on the side or top of the tank body, it is convenient for staff to regularly inspect, maintain, and replace the activated carbon inside the activated carbon adsorption tank.
WORKING PRINCIPLE
Physical Adsorption: It is mainly based on van der Waals forces. When the pollutant molecules in the waste gas come into contact with the surface of the activated carbon, due to the microporous structure and huge specific surface area of the activated carbon, the pollutant molecules will be adsorbed on the surface of the activated carbon, thus achieving the purification of the waste gas. This adsorption effect has a good removal effect on most organic waste gases, such as benzene, toluene, xylene, acetone, formaldehyde, etc., and some small-molecule inorganic waste gases, such as hydrogen sulfide, ammonia, etc.
Chemical Adsorption: Some functional groups on the surface of the activated carbon can undergo chemical reactions with certain specific pollutants to form relatively stable compounds, thereby fixing the pollutants on the surface of the activated carbon. For example, the oxygen-containing functional groups on the surface of the activated carbon can react chemically with sulfur dioxide, converting it into substances such as sulfates, achieving the removal of sulfur dioxide.
PERFORMANCE CHARACTERISTICS
High Adsorption Efficiency: It has a good adsorption effect on a variety of waste gas pollutants. Generally, the adsorption efficiency of organic waste gases can reach more than 80% - 95%, which can effectively reduce the concentration of pollutants in the waste gas and make it meet environmental protection emission standards.
Wide Application Range: It can treat waste gases with different concentrations and flow rates. Whether it is a low-concentration and large-flow waste gas or a high-concentration and small-flow waste gas, effective purification treatment can be achieved by reasonably designing the activated carbon adsorption tank. At the same time, it has a certain adaptability to different types of organic waste gases and some inorganic waste gases.
Stable and Reliable Operation: The equipment has a relatively simple structure and no complex moving parts. Under normal operating conditions, it is not prone to failures. As long as the activated carbon is regularly inspected and replaced, the continuous and stable operation of the equipment can be ensured, providing a reliable waste gas treatment guarantee for the production of enterprises.
Low Maintenance Cost: The daily maintenance of the activated carbon adsorption tank mainly involves regularly checking the operation status of the equipment and replacing the activated carbon. The replacement cycle of the activated carbon depends on factors such as the concentration and flow rate of the waste gas, generally ranging from 3 to 6 months. Compared with some other waste gas treatment equipment, such as catalytic combustion equipment and plasma treatment equipment, the maintenance cost of the activated carbon adsorption tank is relatively low.
APPLICATION
Industrial Waste Gas Treatment: It is widely used in the waste gas treatment of industries such as chemical engineering, electronics, printing, painting, pharmaceuticals, and food processing. For example, the organic waste gas emitted from the reaction kettle in the chemical production process; the volatile organic compound waste gas generated in the circuit board manufacturing process of the electronics factory; the waste gas volatilized from the ink used in the printing process of the printing factory, etc., can all be purified through the activated carbon adsorption tank.
Waste Gas Treatment in Spray Booths: A large amount of waste gas containing organic solvents, such as benzene, toluene, xylene, etc., is generated during the spraying process. The activated carbon adsorption tank can effectively adsorb these organic waste gases, making the waste gas discharged from the spray booth meet environmental protection requirements and protecting the surrounding environment and the health of the staff.
Waste Gas Treatment in Laboratories: During chemical experiments in the laboratory, various harmful gases, such as acid mist, organic waste gases, etc., will be generated. The activated carbon adsorption tank can treat these waste gases to ensure that the gas discharged from the laboratory meets environmental protection standards and provides a safe and healthy working environment for the experimental personnel.
Automobile Exhaust Purification: In some automobile exhaust purification devices, activated carbon adsorption technology is also used to adsorb some harmful substances in the exhaust gas, such as hydrocarbons, etc., assisting devices such as three-way catalytic converters to further improve the purification effect of the exhaust gas and reduce the pollution of automobile exhaust to the atmospheric environment.
