COGAD Granular Activated Carbon Desorption and Regeneration System
The main structure of this unit consists of a desorption and regeneration tank, a catalytic combustion furnace, an induced draft fan, a flame arrestor filter, an electric damper, a pneumatic damper, and an electrical control cabinet. After saturated activated carbon is loaded into the desorption and regeneration tank from the top, the desorption process begins. The exhaust air desorbed from the activated carbon bed enters the main body of the catalytic bed through the air inlet. The exhaust air first passes through the heat exchange chamber of the combustion bed, where it is preheated; it then proceeds to the heating chamber, where heating elements raise the exhaust air to a specified temperature. Once the exhaust air reaches the specified temperature, it passes through multiple layers of precious metal catalysts, where it undergoes catalytic decomposition. The high-temperature purified gas resulting from this decomposition then passes through the heat exchange chamber to preheat the desorbed exhaust air before being discharged from the catalytic bed via the exhaust port.
GADW Granular Activated Carbon Cleaning, Desorption, and Regeneration System
A multi-process, single-tank, centralized granular adsorbent regeneration unit typically refers to a piece of equipment used in the treatment of exhaust air under various operating conditions, where the adsorbent is transferred to a centralized location for regeneration once it reaches adsorption saturation. During use, granular adsorbents not only adsorb VOCs from exhaust air but also adsorb particulate pollutants to varying degrees on their surfaces (in most cases involving particulate-laden exhaust air treatment), which ultimately affects the adsorption efficiency of the granular adsorbent. In such cases, high-temperature desorption alone is insufficient to efficiently regenerate the granular adsorbent; therefore, processes such as washing and decontamination prior to desorption are particularly important. Granular activated carbon is loaded from the top and unloaded from the bottom. After washing and decontamination, desorption and regeneration can be achieved through catalytic combustion or thermal combustion.
