Abstract
Using lye to absorb SO2 as the experimental system, the effect of the packing stator, packing distribution and packing axial height on the gas volume mass transfer coefficient kyae in multilevel cross flow rotating packed bed (MC-RPB) was studied. Further explored the mechanism and enhanced characteristics of MC-RPB to enhance gas film control mass transfer. The results show that the kyae increases with the increase of β, q, u; Compared with model II, kyae increased by about 0.6∼1 times in model I, indicating that in the gas film control system, the filler stator can enhance gas disturbance and effectively strengthen the gas film mass transfer process; When the packing distribution is changed, the kyae increases by 0.2 to 0.4 times in model V compared with model IV, indicating that the end effect zone of MC-RPB is located in the area where the gas just enters the packing layer; When the axial height of the packing layer is changed, the kyae of model IV is 0.1∼0.4 times smaller than that of model III, which further proves that MC-RPB can effectively enhance the gas film mass transfer process.
