分析干法磷肥工艺在普钙生产技术升级中的优势

Analysis of Dry Process in Technology Upgrading Phosphate Calcium Perphosphate Production Advantage

近年来,人们环境保护的意识不断强化,所以在使用化肥的时候需要考虑其环保的特性。在这样的大环境下,积极进行化肥技术的提升十分必要。在化肥生产中,要达到环保的目的,须克服普钙发展的困境,而在普钙的更新换代中,复合化道路是其唯一出路,所以要实现普钙生产中的同步复合化。在普钙同步复合化过程当中,硫酸尿素代替硫酸分解磷矿可以达到目的,但是有干法和湿法两种工艺,通过运用发现干法的优势更加的明显,所以就普钙升级换代中干法的具体优势进行系统的分析。

In recent years, the awareness of environmental protection in China has been constantly strengthened, so it is necessary to consider its environmental protection characteristics when using chemical fertilizer.In the process of synchronous composite calcium sulfate, urea instead of sulfuric acid decomposition of phosphate rock could be achieved, but there are two kinds of dry and wet process, dry process found through the use of more obvious advantages, so this paper analysis the specific advantages in the upgrading of superphosphate dry system.
