介绍磷酸一铵装置扩能技改措施,利用喷雾干燥塔直径由4 800 mm扩大为6 500 mm及增加二级尾气洗涤的工艺方案,产品产量由600 t/d提高到1150 t/d,并成功地解决了尾气的尘、氨、氟达标排放。
The technical measures for the expansion of the capacity of the monoammonium phosphate plant are introduced. The technical scheme of expanding the diameter of the spray drying tower from 4 800 mm to 6 500 mm and increasing the secondary exhaust gas washing is introduced. The output of the product is increased from 600 t / d to 1150 t / d. Successfully solved the exhaust dust, ammonia, fluorine standards discharge.
