Abstract
Unlikethe traditional acid-catalyzed chlorine dioxide (ClO2)generation technology, this study proposes an intensifiedClO(2) generation/utilization mechanism based on rotatingpacked bed (RPB)-enhanced NaClO2 synergistic removal ofsulfur dioxide (SO2) and nitrogen oxides (NOx). The essential of the intensification mechanism is the renewalof a gas-liquid interface caused by the high-gravity environmentin RPB. A theoretical model based on the penetration theory is derivedto evaluate the mechanism. Then, based on the mechanism, a cost-efficientmethod is developed for the synergistic removal process of SO2/NOx. The results indicated that the removal ratesfor SO2 and NOx reached 100% and 91.1%. respectively,under optimal conditions. To simulate the coupling effects of theoperating variables and find the optimal conditions for the process,a T-S-based fuzzy model is established. The error of the fuzzymodel is within & PLUSMN;12%, which proves its reliability for prediction.
