Activated carbon adsorption method is a method that uses porous activated carbon to remove one or more substances from water by adsorbing them on the surface of activated carbon. The removal targets include soluble substances, synthetic detergents, microorganisms, and some heavy metals, and can also decolorize, deodorize, and purify the air.
Activated carbon environmental protection box strong adsorption: The strong adsorption section uses exhaust gas filtration material, which allows exhaust gas particles to collide with glass fibers in the material and be adsorbed. The exhaust gas is further dried into powder in the filtration material. When the material is saturated, it can be removed and cleaned before reuse.
(Type B) Odor removal layer: Honeycomb shaped low resistance activated carbon is selected, which has a large specific surface area, microporous structure, high attachment capacity, and high surface area. The exhaust gas comes into contact with the porous activated carbon with a large surface area, and pollutants in the exhaust gas are adsorbed to separate them from the gas mixture and achieve purification. The pollutants that can be removed include acetic acid, ethyl ester, styrene, odorous substances, etc.
Glass fiber gradually densifies the structure; The windward side is green, and the exhaust side is white. The low compression performance maintains its appearance unchanged, making its filtering fibers conducive to storing oil mist and dust.
Equipment selection
Adsorption tower performance: type, standard type, and economical type. Adsorption tower material: PVC、FRP/PVC、 Galvanized steel sheet and 304 stainless steel
The adsorption of activated carbon involves not only physical adsorption but also chemical adsorption. The adsorption capacity of activated carbon depends not only on its pore structure but also on its chemical composition.
Activated carbon not only contains carbon, but also a small amount of oxygen and hydrogen for chemical bonding and functional group activation, such as carbonyl, carboxyl, phenolic, lactone, quinone, and ether. Some of the oxides and complexes contained on these surfaces come from raw materials, while others are generated by the action of air or water vapor during or after activation. Sometimes surface sulfides and chlorides may also be generated. In the activation process, the minerals contained in the raw materials are concentrated in the activated carbon and become ash. The main components of ash are alkali metal and alkaline earth metal salts, such as carbonates and phosphates.
Methods for distinguishing activated carbon;
1. Coconut shell activated carbon belongs to the category of fruit shell activated carbon, and its main characteristics are low density, light hand feel, and significantly lighter weight when held in hand compared to coal based activated carbon. Coconut shell activated carbon with the same weight generally has a larger volume than coal based activated carbon.
2. Coconut shell activated carbon is generally in the form of broken particles or flakes, while formed activated carbon, such as columnar, is mostly coal based carbon, and spherical, is mostly peat.
Principle of Activated Carbon Environmental Protection Box
When the exhaust gas is powered by a fan and enters the environmental protection box under negative pressure, it enters the activated carbon adsorption layer. Due to the unbalanced and unsaturated molecular gravity or chemical bond force on the surface of the activated carbon adsorbent, when the surface of the activated carbon adsorbent comes into contact with gas, it can attract gas molecules, concentrate and maintain them on the surface of the activated carbon. This phenomenon is called adsorption. By utilizing the adsorption capacity of activated carbon adsorbent surface, the exhaust gas is brought into contact with the porous activated carbon adsorbent on the large surface. The pollutants in the exhaust gas are adsorbed on the surface of the activated carbon, separated from the gas mixture, and the purified gas is discharged at high altitude. Activated carbon environmental protection box is a dry waste gas treatment equipment, consisting of a box body and an adsorption unit filled in the box body.
