Dongguan spray booth waste gas treatment activated carbon adsorption catalytic combustion equipment

Catalytic oxidation combustion system is a process of treating paint spraying waste gas by using paint removal and dehydration device combined with activated carbon fiber adsorption catalytic combustion process
Because the whole system integrates adsorption desorption catalytic combustion
In order to ensure the continuous operation of the system, the adsorber adopts a multi unit shunt combined structure
During normal operation, only one unit is in the desorption state, while other units are in the adsorption or cooling state; After collection, the organic waste gas enters n-1 unit for adsorption through the filter, and the purified gas is discharged into the air
Before normal adsorption, preheat the combustion chamber of the catalytic bed to 300 ℃, after a certain time, when the adsorption of activated carbon fiber in a unit is saturated, open the desorption valve and desorb with 120 ℃ hot air
The desorbed high concentration organic waste gas enters the catalytic bed for combustion and decomposes into CO2 and H2O
After purification, the high-temperature gas preheats the desorbed gas through the tubular heat exchanger, and a small part is discharged through the chimney, The remaining fresh air is returned as desorption hot air, the preheating of electric heating pipe is stopped, and the heat balance of the whole catalytic combustion system is realized through vent valve and make-up cooling fan
