“…Regardless of the large proportion of CO 2 , the direct discharge of SO 2 from the waste gases into the atmosphere will pollute the atmosphere. Once SO 2 is involved in the water cycle of the atmosphere, the acid rain [2] will seriously damage the local ecological environment and cause immeasurable economic losses. Therefore, the national standards for atmospheric emissions are becoming strict, and enterprises are gradually adopting more efficient waste gas purification technology.…”

The combustion of fossil fuels will not only produce a lot of carbon dioxide, but also convert sulfur into sulfur dioxide, which will seriously pollute the atmosphere. Rapid and efficient desulfurization is very important for enterprises that consume a lot of fossil fuels. This paper briefly introduced the sulfur removal principle and the mathematical model of flue gas flow of the wet spray method. After that, the flow field of the desulfurization tower before and after optimization was simulated by ABAQUS software, and the model test was carried out under the similar condition by using the model whose scale was reduced 10 times. The results showed that the velocity distribution of the spray layer and smoke outlet in the section velocity distribution map obtained by numerical simulation was not even and the velocity distribution after optimization was obviously uniform, while the velocity distribution of the demisting layer before and after optimization was relatively uniform and had little change. The results obtained by the test of the model with the reduced scale were close to the numerical simulation results, and the removal rate of sulfur dioxide was greatly improved after optimization.

“…In view of these, RPB has been successfully applied in distillation, absorption, bromination, wastewater treatment, etc. De-SO 2 by the WDFG method in RPB has been studied intensively and industrialized, showing special advantage in deep desulfurization. − In our previous study, RPB has been adopted to absorb NO x with preoxidation by ozone into NaOH solution, and we found that RPB can accelerate the hydrolysis reactions of NO x which are controlling steps of the NO x removal process . However, these studies adopted a low gas–liquid ratio, and the NO x removal efficiency is relatively low.…”

This study employed a rotating packed bed (RPB) to enhance the absorption process of NO x and SO 2 into Na 2 SO 3 solution with the preoxidation by ozone. The absorption performance of NO x and SO 2 was evaluated in terms of removal efficiency (η R ) and overall volumetric mass transfer coefficient (K G a) under various operating conditions including O 3 /NO x molar ratio (MR), rotation speed of RPB (N), gas− liquid ratio (G/L), Na 2 SO 3 concentration (C Na 2 SO 3 ), inlet SO 2 concentration (C SO 2 ), solution pH, and oxygen concentration (C O 2 ). The effect laws of the operating conditions on the η R and K G a of both NO x and SO 2 have been obtained. The results showed that η R values of NO x and SO 2 can reach up to 90 and 99%, respectively. Therefore, this process with the advantages of high efficiency, small size, and simple process for simultaneous absorption NO x and SO 2 exhibits a wide application prospect in the field of flue gas purification.
