Activated Carbon Adsorption and Catalytic Combustion System

Working Principle

Under the suction of the fan, exhaust gas first enters the filtration chamber, where particulate matter is removed. The filtered gas then passes through the activated-carbon adsorption chamber, where organic molecules are captured by the microporous structure of the activated carbon. Clean gas is discharged through the chimney after meeting emission standards.

When the activated carbon reaches saturation, the inlet and outlet dampers close automatically, and the desorption process begins. The desorption fan, heater, and catalytic oxidation unit are activated. Heated air is circulated through the activated-carbon bed to release the adsorbed VOCs, which are then sent to the catalytic combustion chamber.

In the catalytic oxidation chamber, VOCs are heated above 250°C and decomposed into CO₂ and H₂O under the action of the catalyst. The released heat is recovered through a heat exchanger for improved energy efficiency.
