The working principle of activated carbon adsorption chamber is as follows:
When the exhaust gas is powered by the fan, the negative pressure enters the adsorption chamber and enters the activated carbon adsorption layer. Because of the unbalanced and unsaturated molecular gravity or chemical bonding force on the surface of the activated carbon adsorbent, when the surface of the activated carbon adsorbent contacts with the gas, the gas molecules can be attracted and concentrated on the activated carbon. Surface, this phenomenon is called adsorption. Using the adsorptive capacity of the surface of activated carbon adsorbent, the exhaust gas is contacted with the porous activated carbon adsorbent on the large surface. The pollutants in the exhaust gas are adsorbed on the surface of activated carbon to separate it from the gas mixture and discharge the purified gas at high altitude.
Paint exhaust components:
Components of spray paint exhaust and drying exhaust: benzene, bis, styrene, non-methane total hydrocarbons, mainly "triphenyl" and volatile organic waste gas (VOCs) treatment.
Benzene: A hydrocarbon, the simplest aromatic hydrocarbon, is a sweet, flammable, carcinogenic, colorless transparent liquid with a strong aromatic odor at room temperature. It is insoluble in water, soluble in organic solvents, itself can also be used as organic solvents. The ring system of benzene is called benzene ring. The structure of benzene ring after removing a hydrogen atom is called Ph, so the chemical formula of benzene can also be written as PhH. Benzene is a basic material of petrochemical industry, and its output and technical level of production is one of the symbols of the development level of petrochemical industry in a country.
Main components of activated carbon:
Chemical Differentiation of Main Components of Activated Carbon: Carbon and Small Amount of Oxygen, Sulfur and Nitrogen
Process characteristics of activated carbon adsorption unit:
1. It can be divided into manual type and automatic type. It has compact and integrated structure and is easy to install and operate and maintain.
2. High filtration speed, large processing capacity, stable operation effect and less equipment occupation;
3. The filter material has large capacity of intercepting sewage, high porosity, friction resistance and moderate specific gravity.
The selection of waste gas treatment mainly considers: air volume, gas temperature, installation height, the use of environmental temperature, the defogging device before the intake must be properly handled.
Activated carbon adsorption technology has been used for many years in refining and decolorizing industries such as chemical industry and food industry in China. 70 began to be used for industrial wastewater treatment. Activated carbon adsorption has gradually become one of the main methods for the second or third treatment of industrial wastewater. Activated carbon adsorption tower for organic waste gas is widely used in spraying, painting, drying and other places where organic waste gas and odor are produced, such as furniture, wood industry, chemical coatings and metal surface treatment. High-quality activated carbon is used as adsorption medium, and organic waste gas is filtered and adsorbed through multi-layer adsorption layer, so as to achieve the purpose of purifying waste gas.
Scope of application of activated carbon adsorption tower:
Activated carbon adsorption towers are mainly used for the purification of various organic waste gases, especially for the treatment of painting waste gas, ink waste gas, solder waste gas and plastic waste gas.
