Product overview

Honeycomb activated carbon adsorption treatment of organic waste gas is to make use of the characteristic of activated carbon micropores that can absorb organic substances to absorb the organic waste gas of large volume low concentration in the organic solvent to activated carbon and concentrated it, the clean gas directly discharged after adsorption purification. Catalytic combustion desorption is to heat the adsorbed organic solvent in the activated carbon to the boiling point by using the hot air generated from the decomposition of organic waste gas in catalytic combustion, and then introduce the concentrated high concentration waste gas into the catalytic combustion device for thermal oxidation reaction and discharge after reaching the standard.

Process principle description

Honeycomb activated carbon adsorption bed


The principle of honeycomb activated carbon adsorption catalytic combustion desorption is to make use of the strong adsorption characteristic of activated carbon and low boiling point of organic solvent, first use activated carbon adsorption, when the activated carbon adsorption reaches saturation, start the catalytic combustion device, use electric heating to produce a small amount of hot air about 60 ~ 120 ℃ to heat the saturated activated carbon, so that the organic solvent in the activated carbon reaches boiling point to desorption After the thermal oxidation reaction, the high concentration waste gas entering the catalytic combustion device becomes clean and harmless gas and is directly discharged, or enters the heat exchange device, and the high concentration waste gas desorbed from the activated carbon is preheated in the heat exchange device to achieve the goal It is close to the temperature of thermal oxidation, and then the thermal oxidation reaction is carried out in the catalytic combustion device. In this way, only a small amount of heat is provided by the electric heater to reach the thermal oxidation temperature, which reduces the power of the electric heater of the catalytic combustion device, makes the catalytic combustion device and the desorption process of activated carbon achieve low power operation, and reduces the operation cost.
