摘　　要：总结了PTA装置精制干燥机技术改造。改造方案为 :在利用原干燥机的基础上 ,通过改动相应配套部分设备的转速 ,从潜热方面对工艺进行优化 ,从而提高了干燥机的处理能力 ,不但解决了扩能改造中的“瓶颈”问题 。The reformation content of dryer was summarized.The oringinal imported steady rotation rate motor was changed into domestic frequency converter,the rotation rate of it was increased from 4.4 r/min to 6.5 r/min.The rotation rate of feeding screw was increased from 30 r/min to 40 r/min,the rotation rate of discharging screw was increased from 45 r/min to 60 r/min.The original 0.43 MPa heated steam was changed into 1.0 MPa saturated steam.After reformation,the handling ability was 46.6 t/h,the mass fraction of H_2O was below 0.1%.
