DADS Activated Carbon in Situ
Thanks to its enormous specific surface area and rich microporous structure, honeycomb activated carbon can effectively purify organic exhaust air. Its adsorption mechanism is based on physical adsorption: as organic exhaust air pass through the adsorption-desorption bed, intermolecular van der Waals forces attract the organic molecules and cause them to accumulate on the surface of the activated carbon’s micropores. It exhibits superior adsorption capacity for organic substances with high boiling points and large molecular weights. Once adsorption reaches saturation, desorption and regeneration are required; hot air desorption is commonly used. The hot air energizes the organic molecules within the activated carbon’s micropores, enabling them to overcome the adsorption forces and desorb, subsequently being carried out with the hot air. During desorption, the hot air continuously removes the desorbed molecules, creating a concentration gradient. In accordance with Fick’s law, this drives the organic molecules to diffuse from the activated carbon’s micropores into the main gas stream, accelerating desorption. Through this cycle of adsorption and desorption, the honeycomb activated carbon adsorption-desorption bed continuously treats exhaust air, regenerates the activated carbon, and reduces operating costs.
