Abstract

Abstract

A 60000 m³/h regenerative thermal oxidizer(RTO) was used to treat the VOCs exhaust from industrial sources. It was found that the residence time of exhaust in the RTO was insufficient during the RTO was running. The concentration of VOCs in the purified gas fluctuated greatly. Numerical simulation of flow field of the RTO showed that the structure design of combustion chamber of the RTO was unreasonable. In order to solve this problem, in this work, the structure of the combustion chamber was optimized by numerical simulation. RTO design and improvement parameters were determined and applied. Inclined plates and retaining walls were installed in the combustion chamber of the RTO. The narrowed channels of the combustion chamber were extended. The results of the simulation and practical application showed that the structure optimization could effectively improve the uniformity of the flow field distribution at the inlet side of the combustion chamber. The overall turbulence kinetic energy in the combustion chamber was increased. The high temperature area in the combustion chamber was expanded. The fluctuation of the VOCs concentration of the purified gas was greatly reduced in practical optimized operation. The concentration differences between different operation stages were reduced by 78%, as low as about 4 mg/m³. In addition, the removal efficiency(RE) of VOCs remained above 99.5%. The highly efficient purification of industrial VOCs exhaust was realized through the structural simulation, optimization and application of RTO's combustion chamber. It provides strong support for the structural optimization design of RTOs in the future.
