Working Principle:

Heat the organic waste gas to above 760 ℃ (depending on the composition), so that the VOCs in the waste gas are oxidized and decomposed into CO2 and H2O in the combustion chamber. The high-temperature gas generated by oxidation flows through a specially designed ceramic heat storage body, causing the ceramic body to heat up and “store heat”. This “store heat” is used to preheat the incoming organic waste gas, thereby saving fuel consumption for waste gas heating. Ceramic heat storage chambers should be divided into two or more, with each chamber undergoing a sequence of heat storage, release, and cleaning, and working continuously in a loop. After the “heat release” of the heat storage chamber, an appropriate amount of clean air should be immediately introduced to clean the chamber (to ensure a VOC removal rate of over 99%). Only after the cleaning is completed can the “heat storage” program be entered. Otherwise, residual VOCs will be discharged into the chimney along with the flue gas, thereby reducing the treatment efficiency.

Technical advantages:

1. High purification efficiency: VOC purification rate ≥ 99%;

2. High thermal storage efficiency: ceramic thermal efficiency ≥ 95%;

3. High safety factor: multiple protections and interlocks ensure safe operation;

4. Stability of compliance: high purification efficiency, continuously meeting environmental requirements;

5. Low system resistance: Honeycomb thermal storage ceramics have low resistance and low energy consumption;

6. Short installation cycle: modular combination, quick installation;

7. Efficient operation and maintenance: PLC automatic control, using branded accessories, easy maintenance, and cost savings;

8. System composition: The RTO equipment mainly consists of control valves, inlet and outlet pipelines, heat storage chamber, oxidation combustion chamber, burner, gas and combustion support system, compressed air system, control system and other units.

Scope of application:

1. Suitable for medium to high concentration organic waste gases, generally applicable to various organic waste gases with concentrations ranging from 2000-10000 mg/m ³ (while meeting the requirement of less than 25% LEL).

2. The components of exhaust gas that frequently change or contain components that can poison or degrade the activity of catalysts, as well as halogenated hydrocarbons and other corrosive organic gases, can be treated.

3. Silicon containing compounds should be used with caution as they may cause monomer silicon to precipitate and block ceramic heat storage bodies.
