针对磷酸一铵装置循环水有异味的问题,提出取消磷酸一铵(MAP)装置独立循环水系统、MAP装置和湿法磷酸装置共用一个循环水系统的治理方法,包括更换和增加MAP装置的混合冷凝器、循环水泵,以及浓缩三次蒸汽管局部更换。通过技术改造,经一年多的生产运行观察,治理效果显著。 Aiming at the problem of the smell of circulating water in the monoammonium phosphate plant, a solution is proposed to eliminate the independent circulating water system of the monoammonium phosphate (MAP) plant, and the MAP plant and the wet process phosphoric plant to share a circulating water system, including replacing and adding the MAP plant Condenser, circulating pump, and concentrated steam pipe three local replacement. Through technological innovation, after more than a year of production operation observation, the treatment effect is remarkable.
