摘要
Abstract
Distribution of the mass transfer intensity along the radial direction(inner radius and outer radius of the rotor were 70 mm and 200 mm respectively) of the rotor in a rotating packed bed( RPB) was studied. The effects of gas flowrate, liquid flowrate, rotor speed and sulfur dioxide content in the gas phase on the liquid volumetric mass transfer coefficient (KL a) were investigated through sulfur dioxide absorption with countercurrent water. The Results showed that the KL a increased with heightening of gas flowrate, liquid flowrate and rotor speed, did not change much with sulfur dioxide concentration, minished gradually with increase of the packing layer radius in the radius range of 70 -90 mm and increased gradually with increase of the radius when it was more than 90 mm. Furthermore, the results confirmed that both the inner end effect zone and the outer end effect zone existed in the packing layer in the RPB.关键词
