Product Detail


Summary


Activated carbon adsorption-desorption + (CO) catalytic purification device is our company accumulated years of waste gas treatment experience, developed a new series of high efficiency, energy saving, non-secondary pollution products.After dozens of users to use, confirmed that similar products can reach the leading domestic level.Activated carbon (AC) is a porous non-polar material with good adsorption properties for volatile organic compounds (VOCs).Activated carbon (AC) is a porous non-polar material with good adsorption properties for volatile organic compounds (VOCs).The activated carbon bed made of activated carbon as adsorption material has a wide range of functions in the treatment of industrial organic waste gas, odor waste gas and so on. it has the advantages of low initial investment cost, simple equipment structure and good purification effect.The activated carbon bed made of activated carbon as adsorption material has a wide range of functions in the treatment of industrial organic waste gas, odor waste gas and so on. it has the advantages of low initial investment cost, simple equipment structure and good purification effect.Activated carbon adsorption and catalytic oxidation (CO) desorption and regeneration technology is developed on the basis of single-activated carbon adsorption bed, and the addition of activated carbon regeneration device, organic waste gas thermal oxidation and heat recovery, multi-channel safety detection and automatic control as one of the organic waste gas purification system.



Fundamental principles


According to the adsorption (high efficiency) and catalytic combustion (energy-saving) design of two fundamental principles, the use of two gas channels for continuous operation, a catalytic combustion chamber, two or more adsorption bed alternative use.Firstly, the organic waste gas is adsorbed by active carbon, and the adsorption is stopped when it is almost saturated, and then the organic matter is desorbed from the activated carbon by hot air flow to make the activated carbon regenerated.The desorbed organic matter has been concentrated (tens of times higher than the original concentration) and sent to the catalytic combustion chamber for catalytic combustion of carbon dioxide and water vapor emissions.When the concentration of the organic waste gas reaches more than 2000PPm, the organic waste gas can maintain spontaneous combustion in the catalytic bed without external heating.A portion of the combustion exhaust is discharged into the atmosphere and most of it is sent to the adsorption bed for regeneration of activated carbon.This can meet the needs of combustion and adsorption of heat energy to achieve the purpose of energy saving.After regeneration can enter the next adsorption;When desorbing, the purification operation can be carried out in another adsorption bed, which is suitable for both continuous and discontinuous operation.

 


Adsorption process: under the action of the induced draft fan, the organic waste gas is first pretreated by a 2-stage bag filter to remove dust particles and debris, and then is absorbed and purified by an activated carbon adsorption unit to meet the emission requirements.


Desorption process: when the activated carbon adsorption bed reaches saturation, the adsorption is stopped, and then the organic matter is desorbed from the activated carbon by the hot gas stream to make the activated carbon regenerated.
