汽提塔分布管的修复与应用

Repair and Application of Stripper Distribution Pipe

尿素装置汽提塔随使用年限增加,分布管上的三个出液小孔受冲刷腐蚀增大,单位时间进入汽提管中尿液量增加,汽提塔效率下降。通过对分布管加工修复,达到了新分布管各项指标要求,满足使用条件,实际应用后效果较好,可推广修复利用。

With the increase of the service life of the stripper in urea plant,the erosion corrosion of the three outlet holes on the distribution pipe increases,the amount of urine entering the stripper per per unit time increases,and the efficiency of the stripper decreases.Through the processing and repair of the distribution pipe,the requirements of each index of the new distribution pipe are met,the application conditions are met,the effect is good after practical application,and the repair and utilization can be popularized.
