摘要
Abstract
Specific surface area and mass transfer rate in spray tower were studied by considering the forces acting on a droplet. Absorption region was divided into accelerating segment and constant speed segment, and a segmentation calculation model for the height of absorption region was developed, which was verified by the data of four industrial desulfurization systems. The effects of operating parameters on the height of absorption region were investigated. The results show that height of absorption region decreases with the decrease of spray density and pH value of absorbent, and increases with the decrease of droplet diameter, superficial gas velocity and inlet SO2 concentration. The desulfurization efficiency increases with the height of absorption region. When the desulfurization efficiency reaches above 90%, the height of absorption region only has a slightly influence on the efficiency.关键词
