摘要
空气干燥是燃硫法SO3／空气连续磺化重要组成部分。本文提出了根据不同地区的气候特点确定硅胶干燥器工作周期，分析了吉林地区气候实际情况，结合本厂实际确定了硅胶干燥工作周期并建议冬季停开空气冷却系统。
Air supply system is an important unit of SO3 continuous sulfonation plant. The regenerationtime of air dryer should be determined by moisture of the air. According to the air conditions of northeast Chinain winter. Regenration time can be extended and the air cooling system can be stopped.
