The catalytic combustion integrated machine is designed according to the two basic principles of adsorption (high efficiency) and catalytic combustion (energy saving). It adopts two gas paths to work continuously. One catalytic combustion chamber and two or more adsorption beds are used alternately. Firstly, the organic waste gas was adsorbed with activated carbon, and then the adsorption was stopped when the organic waste gas reached saturation, and then the organic matter was desorbed from the activated carbon by hot gas flow to regenerate the activated carbon; The desorbed organic matter has been concentrated (the concentration is dozens of times higher than the original) and sent to the catalytic combustion chamber for catalytic combustion to generate carbon dioxide and water vapor.
When the concentration of organic waste gas is more than 2000 ppm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating. Part of the tail gas after combustion is discharged into the atmosphere, and most of it is sent to the adsorption bed for activated carbon regeneration. In this way, the heat energy needed for combustion and adsorption can be met, and the purpose of energy saving can be achieved. The regenerated can enter into the next adsorption; During desorption, another adsorption bed can be used for purification, which is suitable for continuous operation and intermittent operation.
Activated carbon adsorption process: under the action of induced draft fan, the organic waste gas is pretreated by the 2-stage bag filter to remove dust particles and impurities, and then it is adsorbed and purified through the activated carbon adsorption unit to meet the emission requirements.
Activated carbon desorption process: when the activated carbon adsorption bed is nearly saturated, the adsorption is stopped, and then the organic matter is desorbed from the activated carbon by hot gas flow to regenerate the activated carbon.
