在线配酸技术在磷酸二铵生产中的应用

Use of On-Line Acid Blending Technique in Production of Diammonium Phosphate

磷酸二铵生产装置一直采用淤渣磷酸调整产品富余养分,但存在磷酸贮槽倒槽频繁、产品养分波动大等问题。采用在线配酸技术对磷酸二铵生产装置进行改造后,不仅产品养分调整快速、灵活,减少了不合格品的产生量,而且磷酸贮槽的运行周期延长,减少了清槽的频次。

The diammonium phosphate production plant is used to use sludge phosphoric acid to adjust product excess nutrient, but there exist problems of frequent equipment cleaning of phosphoric acid storage tank, and large fluctuation of product nutrient content. After the revamp of the diammonium phosphate production plant with on-line acid blending, not only the adjusting product nutrient is fast and flexible, reducing output of non-conforming product, but also the operation period of phosphoric acid storage tank is prolonged, decreasing frequency of storage tank cleaning.
