I. Overview of activated carbon adsorption filter Activated carbon adsorption filter is also called activated carbon adsorption tower, activated carbon adsorber, activated carbon adsorption device in exhaust gas treatment equipment. GHF series activated carbon adsorption filter (tower) is an environmental protection equipment product developed by our company to filter and absorb odors. The activated carbon adsorption tower has the advantages of high adsorption efficiency, wide application, convenient maintenance, and can handle multiple mixed exhaust gases at the same time. Activated carbon has the functions of removing harmful gases such as formaldehyde, benzene, TVOC, and disinfection and deodorization. Activated carbon adsorption towers are now widely used in the production of electronic components, battery (battery) production, pickling operations, laboratory exhaust, metallurgy, chemical industry, and medicine. , Coating, food, brewing and other waste gas treatment, which is most suitable for the purification of spray paint waste gas treatment.
Second, the working principle Organic exhaust gas is powered by a fan, and positive or negative pressure enters the tower of the activated carbon adsorber. Because of the unbalanced and unsaturated molecular gravity or chemical health on the solid surface of activated carbon, when this solid surface and When the gas comes into contact, it can attract gas molecules, make them condensed and remain on the solid surface, and the pollutants are adsorbed. After passing through the filter, the exhaust gas enters the equipment dust exhaust system, and the purified gas reaches the standard and is discharged at high altitude.
3. Brief Introduction of Technology Activated carbon is a kind of black powdery, granular or pellet-shaped amorphous porous carbon. The main ingredient is charcoal, which also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, and chlorine. It also has a fine structure like graphite, except that the grains are small and the layers are irregularly stacked. Has a large surface area (500 ~ 1000㎡ / g). Has a strong adsorption capacity, can adsorb gas, liquid or colloidal solid on its surface. For gas and liquid adsorption can be close to the quality of activated carbon itself.
Its adsorption is selective, non-polar substances are easier to adsorb than polar substances. In the same series of substances, the substances with higher boiling points are more likely to be adsorbed, the higher the pressure, the lower the temperature, the higher the concentration, the larger the adsorption amount, and conversely, decompression and temperature increase are favorable for the desorption of the gas.
Activated carbon is often used for gas adsorption, separation and purification, solvent recovery, sugar liquid, grease, glycerin, decolorant for drugs, deodorant for drinking water or refrigerator, gas filter for gas masks, and can also be used as catalyst or metal salt. A truncation of the catalyst.
When the organic exhaust gas is powered by a fan, positive pressure or negative pressure enters the tower body. Because of the unbalanced and unsaturated molecular gravity or chemical health on the solid surface of activated carbon, when this solid surface is in contact with the gas, it can be Attract gas molecules, make them condensed and keep them on the solid surface. Pollutants and odors are adsorbed. After passing through the activated carbon adsorption tower, the exhaust gas enters the equipment's dust extraction system, and the purified gas meets the high-level emission standards.
1. Advantages of activated carbon adsorber products:
① High adsorption efficiency and wide application area;
② Convenient maintenance without technical requirements;
③ Can handle multiple mixed exhausts at the same time.
2. Disadvantages of activated carbon adsorber products: higher operating costs;
3, activated carbon adsorber classification: can be divided into square or round.
4. Scope of application of activated carbon adsorption filter:
Activated carbon adsorbers are mainly used in: exhaust gas purification in the production of electronic components, battery (battery) production, pickling operations, laboratory exhaust, metallurgy, chemical industry, medicine, painting, food, brewing and furniture production. For the treatment and purification of paint exhaust gas.
