INTRODUCTION

The activated carbon adsorption box is an environmentally friendly equipment with a scientifically and reasonably designed structure and powerful functions. It has a simple appearance and strong practicability, and can be well adapted to the layout of various industrial sites. Its outer shell is usually made of high-quality carbon steel or stainless steel. Through fine processing techniques, it has good sealing performance and sturdiness, which can effectively prevent gas leakage and adapt to complex working conditions.

The core internal component is naturally activated carbon. The selected activated carbon has the characteristics of a developed pore structure, a large specific surface area, and excellent adsorption performance. Coconut shell activated carbon, columnar activated carbon and other materials are commonly used high-quality ones. These activated carbons are orderly filled in the adsorption box, and combined with a reasonable air flow channel design to ensure that the gas containing pollutants can evenly pass through the activated carbon layer and fully contact the activated carbon, so that the harmful components in it can be adsorbed to the greatest extent, thereby achieving efficient purification of waste gas and odors. It is widely used in many environmental protection treatment links in industrial fields.

WORKING PRINCIPLE

When the gas containing various pollutants, such as organic waste gas and odorous gas, enters the activated carbon adsorption box, it will first be evenly dispersed along the preset air inlet channel and then slowly flow through the area filled with activated carbon. During this process, activated carbon exerts a powerful adsorption effect by virtue of its rich pore structure and large specific surface area. 

Harmful molecules in the gas, such as volatile organic compounds (VOCs), benzene series compounds, sulfides, ammonia, etc., will be adsorbed and attached to the pores of the activated carbon under the action of intermolecular forces and the principle of physical adsorption, thus realizing the separation from the clean gas. After the gas is treated by activated carbon adsorption, the content of pollutants in it is greatly reduced, achieving the purification effect. Finally, the purified gas is smoothly discharged out of the adsorption box through the air outlet channel, making the gas discharged into the external environment cleaner and harmless.

As the adsorption process continues, the pollutants adsorbed on the surface and in the pores of the activated carbon will gradually increase. When the adsorption saturation is reached, the adsorption effect will decline. At this time, it is necessary to replace or regenerate the activated carbon to restore its good adsorption performance and ensure that the adsorption box can continuously and effectively play its purification role.

MAIN PERFORMANCE AND FEATURES

(I) High Adsorption Capacity

The activated carbon adsorption box has an excellent adsorption effect on many common gaseous pollutants, especially for the purification of low-concentration and large-air-volume organic waste gas and odorous gas. For benzene series compounds such as benzene, toluene, and xylene, the removal efficiency can reach about 80% - 95%, which can effectively reduce the concentration of pollutants in waste gas and make it meet the environmental protection emission requirements, making a significant contribution to improving the surrounding atmospheric environment.

(II) Wide Application Range

It can be applied to almost all industrial scenarios where organic waste gas or odors are generated. Whether it is the complex organic waste gas generated in industries such as chemical industry, coating, printing, and electronics, or the unpleasant odors emitted from places such as food processing, sewage treatment, and garbage disposal, the activated carbon adsorption box can play a role in targeted adsorption and purification, with extremely strong versatility.

(III) Stable and Reliable Operation

The equipment itself does not have complex mechanical moving parts and high-precision components that are prone to failure. The overall structure is relatively simple and stable. As long as the activated carbon is filled in accordance with the specifications and the daily maintenance is carried out, it can operate stably for a long time, reducing the downtime caused by equipment failures and ensuring the continuity of industrial production and environmental protection treatment work.

(IV) Simple and Easy Operation

Its operation interface is clear and intuitive. Operators only need to undergo simple training to easily master the basic operations such as starting, stopping, and adjusting the daily operation parameters of the equipment. Moreover, the daily maintenance of the equipment mainly focuses on regularly checking the adsorption situation of the activated carbon and timely replacing the saturated activated carbon. It does not require complex professional skills and cumbersome operation procedures, which is convenient for enterprises to manage and maintain.

(V) High Degree of Customization

The activated carbon adsorption box can be flexibly customized in multiple aspects such as external dimensions, treatment air volume, types of activated carbon, and filling amount according to the actual needs of different users. For example, for enterprises with limited space but in need of treating a large amount of waste gas, a compact adsorption box with a suitable treatment air volume can be customized; for waste gas with more specific pollutant components, more targeted activated carbon can also be selected for filling to achieve the best adsorption effect and meet diverse usage scenarios.

APPLICATION FIELDS AND INDUSTRIES OF THE PRODUCT

Chemical Industry

During the chemical production process, a large amount of waste gas containing various organic compounds and odorous substances will be generated. For example, the waste gas generated in the production processes of synthetic rubber, plastics, pesticides, and dyes has a complex and harmful composition. The activated carbon adsorption box can conduct in-depth adsorption and purification on these waste gases, remove volatile organic compounds, malodorous substances, etc., reduce the pollution to the surrounding environment, ensure that the chemical production meets the environmental protection requirements, and also help to improve the working environment in the workshop and protect the health of workers.

Coating Industry

The processes of spraying and baking in the coating industry will generate waste gas formed by the volatilization of organic solvents such as benzene series compounds, esters, and ketones. These waste gases not only have a pungent smell but also cause great harm to the atmospheric environment. By using the activated carbon adsorption box, these organic solvents can be effectively adsorbed, the content of pollutants in the waste gas can be reduced, the discharged gas can meet the environmental protection emission standards, and the odor in the workshop can be alleviated at the same time, creating a good working atmosphere and improving the quality and appearance effect of coated products.

Printing Industry

During the ink printing process, the organic waste gas generated by the volatilization of organic solvents is the main source of pollutants. These waste gases contain harmful substances such as benzene, toluene, and xylene, and also have an unpleasant smell. Relying on its powerful adsorption performance, the activated carbon adsorption box can accurately adsorb the harmful components in these waste gases, purify the air in the workshop, avoid the pollution of the surrounding environment caused by waste gas emissions, ensure the environmental protection compliance operation of printing enterprises, and protect printing equipment from being eroded by waste gas and extend the service life of the equipment.

Food Processing Industry

Food processing workshops often emit various odors, such as the fishy smell of meat processing, the burnt smell of baked goods, and the sour smell of dairy product processing. These odors not only affect the workshop environment but also may affect the quality of food. The activated carbon adsorption box can quickly and effectively adsorb these odorous gases, keep the air in the workshop fresh, create a good hygienic environment for food processing, meet the strict hygienic standards of food production, and ensure food safety.

Sewage Treatment Industry

During the process of sewage treatment in sewage treatment plants, some gases with a foul smell, such as hydrogen sulfide and ammonia, will be generated. These gases will cause serious air pollution when emitted into the air and affect the quality of life of surrounding residents. The activated carbon adsorption box can adsorb and treat these malodorous gases, convert them into clean and odorless gases and discharge them, effectively improving the atmospheric environment around the sewage treatment plants, reducing the negative impact on the surrounding environment, and fulfilling environmental protection responsibilities.

Electronics and Electrical Appliance Industry

Some processes in the manufacturing of electronics and electrical appliances, such as circuit board cleaning and welding, will generate waste gas containing volatile organic compounds. If these waste gases are not treated, they will not only pollute the environment but also may damage precision electronic components. The activated carbon adsorption box can effectively adsorb and purify these waste gases, ensure the air quality in the production workshop, protect electronic equipment, and also meet the increasingly strict environmental protection requirements in the industry, helping enterprises achieve sustainable development.
