简要分析影响大颗粒尿素装置运行周期的设备因素,同时也总结了喷射风风量不够、流化风风量不够、床层过高、床层温度过高、尿液中水含量过高、甲醛加入量过低、尿液中含缩二脲过高以及异常天气等特殊的运行工况,同样是导致大颗粒尿素装置运行周期缩短的因素。 Briefly analyze the equipment factors that affect the operation cycle of large particle urea plant, and also sum up the insufficiency of jet air volume, fluid air volume is not enough, the bed is too high, the bed temperature is too high, the urine water content is too high, Low, biuret urine containing high and abnormal weather and other special operating conditions, the same is the result of large urea plant run shortened factors.
