The computer\|aided design method of spray drying tower is discussed in this paper. The droplet moving process is divided into different regions, in turbulent and laminar flow regions, the direct integral formulas for calculating diameter and height of tower are given, and in transition flow region, the numerical integration is used. It can be conveniently used to design spray drying tower with higher accuracy and less calculation. The calculation results show that, in transition flow region, the calculating accuracy is much affected by integral step size.
