硝酸钾生产中防结垢方法

Scale Prevention Method in Production of Potassium Nitrate

分析了KNO3 生产中设备结垢的原因 ,总结出采用提高溶液中NH+4 浓度、加入表面活性剂。

The causes are analyzed for scaling of equipment in the production of potassium nitrate, and a summary is made, indicating that scaling will be reduced and prevented by in creasing the NH + 4 concentration in the solution, adding surfactants and using the self cooled crystallization method.
