| How It Works
The three-chamber RTO achieves exhaust gas purification and thermal energy recovery by periodically switching the airflow direction among its three heat-storage chambers.
Waste gas preheating stage: The waste gas enters the first thermal storage chamber, where it is heated to the oxidation temperature (760–1000°C), and then flows into the combustion chamber, reacting to produce carbon dioxide and water vapor.
Purification gas cooling stage: The high-temperature purification gas enters the second heat-storage chamber to release heat, and after being cooled, it is discharged by a fan.
Rinse-and-clean phase: Use a portion of the purified gas to flush the third regenerative chamber, removing residual exhaust gases before moving on to the next cycle.
| Purification Efficiency
The VOCs removal rate of the three-chamber RTO can reach over 98%, significantly higher than that of the two-chamber RTO (95%–98%). Its advantages include:
By processing in three staged heat-storage chambers, ensure that the exhaust gas undergoes thorough oxidation at high temperatures;
Each heat-storage chamber alternates between heat storage, heat release, and cleaning operations, enabling continuous operation.
| Applicable Scenarios
Suitable for treating industrial exhaust gases with medium to high concentrations (1–10 g/m³), including organic compounds such as alkanes, alkenes, and alcohols generated from industries like chemical manufacturing, pharmaceuticals, coating, and printing. The system handles air volumes ranging from 5,000 to 300,000 m³/h, with a thermal energy recovery rate exceeding 95%.
