硝盐联产技术在元明粉生产中的应用

Application of Nitrate Combined Production Technology in the Production Process of Yuanmingfen

在传统制硝中产生的含盐母液因无法有效分离,只能外排,这样就造成了资源的严重浪费,排出的母液还会对水流造成严重污染。在这样的情况下,硝盐联产技术在元明粉生产过程中的应用,有效地解决了这一困境,硝盐联产的主要产品是元明粉,副产品是盐,利用硫酸钠和氯化钠共饱和溶液在不同压力和温度下析出晶体,高效实现了分离硝盐,对整个元明粉生产企业有积极的推动作用,因此,主要对硝盐联产技术在元明粉生产过程中的应用进行分析。

The salt-containing mother liquor produced in traditional nitration cannot be effectively separated,and can only be drained out.This causes a serious waste of resources,and the discharged mother liquor will also cause serious pollution to the water flow.Under such circumstances,the application of nitrate co-production technology in the production process of Yuanming powder has effectively solved this dilemma.The main output of nitrate production is Yuanming powder by-product is salt.Crystals of sodium chloride precipitated in the co-saturated solution at different pressures and temperatures.The high-efficiency separation of nitrate has a positive effect on the entire Yuanming powder production enterprise.Therefore,it mainly analyzes the application of nitrate co-production technology in the production process of Yuanming powder.
