Activated carbon adsorption unit

A, adsorption treatment of the basic principles of organic waste

Because there is not a balance and unsaturated molecular attraction force or bonds on a solid surface, so when the solid surface in contact with the gas, we can attract the gas molecules to uptake and to maintain a solid surface, this phenomenon is called adsorption . Adsorption method is the use of the adsorption capacity of the solid surface, so that the exhaust gas and the porous solid material in contact with a large surface, the exhaust gas contaminants are adsorbed on the solid surface, so that separation of the gas mixture, so as to achieve the purpose of purification.

Depending on the gas molecules and solid surface molecular forces, adsorption can be divided into physical adsorption and chemisorption, the former is the result of intermolecular forces, which are the result of the formation of chemical bonds between molecules. Using granular activated carbon adsorption is physical adsorption.

B, the adsorbent material

Traditional as organic waste gas purification adsorbent material activated carbon, silica gel, molecular sieve, activated carbon particles in which the most widely used, the effect is the best. The reason is that only the attachment of other agents (e.g., silica gel, metal oxides, etc.), polar, under conditions of coexistence of steam, water molecules and molecules binding adsorbent material, thereby reducing the adsorption properties of the adsorbent material, and activated carbon Molecular difficult phase structure with polar molecules, thereby increasing the ability to adsorb organic waste.
