Recycling Regenerative Catalytic Oxidizer Energy Saving Continuous Operation

Energy-saving continuous operation catalytic oxidizer with consumption reduction and low operating costs.

The heat storage catalytic furnace achieves breakthroughs in both energy conservation and environmental protection. With low energy consumption and high purification rates, it serves as a key enabler for corporate green development. The efficient heat storage system and catalytic reaction technology reduce energy consumption while minimizing pollutant emissions, aligning with sustainable development principles. The equipment offers long service life and minimal maintenance costs, providing substantial long-term capital savings. High automation levels and user-friendly operation simplify environmental compliance management while enhancing competitiveness.

Untreated waste gas initially passes through a pre-stage water seal tank equipped with demisting section to remove moisture and particulate matter. The gas is then pressurized by a waste gas fan and directed through a flame arrester into the ceramic heat storage layer of the regenerative chamber, where it preheats to approximately 350°C.

Preheated gas enters the catalytic layer where organic components undergo complete oxidation and decomposition under catalyst action. An electric heating device in the flue gas diversion channel ensures catalytic bed outlet temperature reaches 400°C, guaranteeing thorough destruction of organic pollutants.

Resulting flue gas undergoes secondary distribution through the diversion channel into another set of regenerative chambers, exchanging heat with ceramic heat storage packing. After heat recovery, cooled flue gas discharges through a chimney into the atmosphere, meeting emission standards.

The Regenerative Catalytic Oxidizer (RCO) utilizes two insulated chambers filled with high-temperature ceramic media. During operation, the process stream enters an energy recovery chamber where ceramic media preheats it before introduction to the oxidation chamber. As the stream moves through the inlet bed, its temperature rises.

After oxidation in the combustion chamber through catalyst action, pollutants convert to CO₂ and water vapor, releasing thermal energy. Clean gas exits through the second recovery bed, leaving heat in the ceramic media to preheat the inlet stream in the next cycle. Combining catalyst and ceramic media, RCO significantly reduces fuel consumption during thermal oxidation and preheating, resulting in lower operating costs.
