1、 Introduction to activated carbon adsorption unit:
Activated carbon adsorption device is the purification equipment with the best treatment effect for organic waste gas and odor. Activated carbon adsorption is an effective measure to remove odor, synthesize dissolved organic matter and micro pollutants. Most large organic molecules, aromatic compounds and Haloalkynes can be firmly adsorbed on the surface or gap of activated carbon, and have obvious removal effect on humus, synthetic organic matter and low molecular weight organic matter. Activated carbon adsorption, as a deep purification process, is commonly used in the final treatment of wastewater and waste gas purification.
2、 Working principle:
The activated carbon adsorption device is mainly composed of an activated carbon layer and a supporting layer. Activated carbon has developed voids, large specific surface area and high adsorption capacity. It is precisely because of this characteristic of activated carbon that it is widely used in advanced water treatment, such as domestic water supply, advanced treatment of sewage (purified water) in the later stage, etc.
After using activated carbon for a period of time, it adsorbs a large amount of adsorbate, gradually tends to saturation and loses its working capacity. In serious cases, it will penetrate the filter layer. Therefore, activated carbon should be regenerated or replaced.
The main function of the supporting layer is to prevent the loss of activated carbon from the equipment and play a certain role in uniform water distribution during water outlet and backwashing.
3、 Equipment features:
Organic waste gas activated carbon adsorption tower is widely used in places where organic waste gas and peculiar smell are generated by spraying, painting and drying of furniture, wood industry, chemical coatings and metal surface treatment. High quality adsorption activated carbon is used as the adsorption medium, and the organic waste gas is filtered and adsorbed through multi-layer adsorption layers, so as to achieve the purpose of purifying waste gas.
4、 Main technical features:
◆ it is divided into manual type and automatic type, with compact and integrated structure and easy installation, operation and maintenance;
◆ high filtration rate, large treatment capacity, stable operation effect and less equipment land occupation;
◆ the filter material has large sewage interception capacity, high porosity, friction resistance and moderate specific gravity
5、 Purpose:
Activated carbon is widely used in the deep purification of drinking water, industrial water and wastewater; Separation, purification and purification of various gases; Organic solvent recovery; Decolorization, deodorization and refining of sugar, monosodium glutamate, medicine, liquor and beverage; Precious metal refining; In the chemical industry, fruit shell activated carbon also acts as catalyst and catalyst carrier.
