Numerical Simulation of Two-Component VOCs Gas Treatment in a Three-Bed Regenerative Oxidation Furnace

At present, most research on the three-bed regenerative oxidation furnace only stays at the level of numerical simulation of combustion after a single-component gas enters the device. However, in actual printing and packaging companies, the gas components are diverse and complex. Therefore, in order to be as close as possible to the actual production situation, this paper selects two gases that account for a larger proportion in VOCs exhaust gas for research: toluene gas with higher calorific value and ignition point, and ethyl acetate gas with lower calorific value and ignition point. The three-dimensional model and fluid domain model of the three-bed regenerative oxidation furnace were established using Solidworks software, and numerical simulation was carried out using the computational fluid dynamics (CFD) software Fluent. The thermal efficiency changes of the operating device under different proportion conditions were studied. The numerical calculation results can guide the precise adjustment and control of the actual production of the three-bed regenerative oxidation furnace.
