Engineering Case of Catalytic Combustion Unit for Adsorption and Desorption of Activated Carbon

The device is designed on the basis of two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving). It works continuously with two gas paths, one catalytic combustion chamber and two or more adsorption beds alternately. The organic exhaust gas is first adsorbed by activated carbon, and then desorbed by hot air to regenerate activated carbon. The desorbed organic matter has been concentrated (the concentration is more than ten times higher than the original) and sent to catalytic combustion chamber for carbon dioxide combustion and water vapor discharge. 。 When the concentration of organic waste gas is over 2000 PPm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. After combustion, part of the exhaust gas is discharged into the atmosphere, and most of it is sent to the adsorption bed for regeneration of activated carbon. In this way, the thermal energy required for combustion and adsorption can be satisfied, and the purpose of energy saving can be achieved. After regeneration, the activated carbon can enter the next adsorption; during desorption, the purification operation can be carried out in another adsorption bed, which is suitable for both continuous operation and intermittent operation.
