Activated carbon adsorption desorption catalytic combustion (RCO)
Designed using a process flow of pre-treatment → activated carbon adsorption → desorption regeneration → catalytic combustion, adopting a multi gas path working mode. The workflow is as follows: after the waste gas is collected and pre-treated to remove particulate matter or water mist, it enters the activated carbon adsorption unit for adsorption, and the purified air is discharged into the atmosphere. After the adsorption unit is saturated, stop the adsorption operation and use the hot air flow after catalytic combustion to desorb the organic matter from the activated carbon for regeneration. The heat from the upper and lower heat exchange chambers of the catalytic decomposition chamber is sent to the unit for desorption through a high-temperature fan. The concentrated organic waste gas after desorption returns to the catalytic decomposition chamber through a pipeline for decomposition and combustion. The heat generated after combustion is recycled, while reducing the electrical energy required for catalytic decomposition heating. The organic matter after desorption has been concentrated (with a concentration several tens of times higher than before, reaching over 2000ppm) and sent to a catalytic burner for catalytic reaction to produce CO2 and H2O for discharge.
1. Low investment: low cost of activated carbon, mature market;
2. Activated carbon can be recycled after desorption and regeneration, reducing the cost of replacing activated carbon in the later stage;
3. Low operating cost, high air volume and low concentration waste gas are concentrated into high concentration and low air volume waste gas. The heat generated during the catalytic process can basically maintain operation without the need for additional heating
4. Easy to operate, safe and reliable: Equipped with a PLC control program, it can automatically run and detect operating parameters; Setting up multiple safety protection measures
