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 secondary or tertiary 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.
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 waste gas treatment equipment composition:
The equipment is mainly composed of air inlet section, tower body, filter element, differential pressure meter, air outlet section, etc.
Activated carbon waste gas treatment equipment is a dry waste gas treatment equipment. The utility model is composed of a box body and an adsorption unit packed in the box body. According to the number of adsorption units and air volume, it can be divided into several specifications. Activated carbon waste gas treatment equipment can deal with a variety of different waste gases by choosing different fillers.
Only when we really understand the waste gas that needs to be treated can we get better treatment. To some extent, using activated carbon waste gas treatment equipment can help us better deal with the waste gas produced in industrial production.
Technical Introduction:
Activated carbon is often used as decolorizer for gas adsorption, separation and purification, solvent recovery, sugar solution, oil, glycerol and substances. When organic waste gas is powered by a fan, it enters the tower under positive or negative pressure. Because of the unbalanced and unsaturated molecular gravity or chemical health on the solid surface of activated carbon, when the solid surface contacts with gas, it can attract gas. Molecules are concentrated and maintained on the solid surface. Pollutants and odors are absorbed. After the exhaust gas passes through the activated carbon adsorption tower, it enters the equipment dust exhaust system to purify the gas to meet the discharge standards at high altitude.
After using activated carbon for a period of time, a large number of adsorbates are adsorbed, gradually becoming saturated and losing the working ability. In serious cases, activated carbon will penetrate the filter layer. Therefore, the regeneration or replacement of activated carbon should be carried out.
