摘　　要：介绍云南磷化集团有限公司800 kt/a硫黄制硫酸装置干燥塔运行情况。针对干燥塔阻力降增加的原因,制定干燥塔填料技改方案。技改方案实施后,透平机组运行转速由4650 r/min下降至4450 r/min,干燥塔阻力降下降63%,可满足装置满负荷运行,经济效益显著。The operation of drying tower in 800 kt/a sulfur-burning sulfuric acid plant in Yunnan Phosphate Group Co.,Ltd.is introduced.In view of the reason of the resistance increase of the drying tower,the packing technical scheme of the drying tower is formulated.After the implementation of technical transformation scheme,the running speed of turbine unit is decreased from 4650 r/min to 4450 r/min,and the resistance drop of drying tower is decreased by 63%,which can meet full load operation of the unit,and economic benefit is remarkable.
