通过大颗粒尿素造粒装置粉尘洗涤器回收尿液,并将其加入到蒸发系统,分析此操作对前系统的影响,对比将尿液加入真空预浓缩器分离器还是加入真空浓缩器的加入点,在实际生产中调节蒸发预浓缩的压力与蒸发系统蒸汽用量的对应关系,最终确定回收尿液加入点,选取的最优方案是加入真空预浓缩器分离器,在生产中降低了蒸汽耗量,实现提质增效。

Abstract:
In the process of production, the inherent characteristics of the centrifugal compressor are affected by the varying process parameters under various working conditions, which makes the compressor prone to surge. By setting up the anti-surge control logic via the ITCC control system,the surge problem of the unit is prevented to the maximum,ensuring the safe,stable and long period operation of the device.
