摘要
用氯化钾与硝酸铵复分解生产硝酸钾与氯化铵过程中,原料氯化钾中浮选剂对硝酸钾生产过程影响主要在两个方面:第一,原料氯化钾中浮选剂吸附不溶物杂质形成一层红棕色油脂状物,漂浮在溶液表面,污染产品颜色,粘壁堵塞管道;第二,原料氯化钾中脂肪胺类浮选剂,它将捕捉浮选氯化铵晶体使之悬浮在溶液表面,但它对硝酸钾没有捕捉浮选效果;氯化钾中吗啉类浮选剂,它对硝酸钾与氯化铵均没有捕捉浮选效果。
In the process of metathesis of potassium chloride and ammonium nitrate to produce potassium nitrate and ammonium chloride,the effect of the flotation agent in the raw material potassium chloride on the production process of potassium nitrate is mainly in two aspects: firstly,the flotation agent in the raw material potassium chloride absorbs insoluble impurities forming a layer of reddish-brown grease,floating on the surface of the solution,contaminating the color of the product,and blocking the pipeline;secondly,the fatty amine flotation agent in the raw material potassium chloride can capture ammonium chloride crystal and suspend it on the surface of the solution,but it has no flotation effect on potassium nitrate;morpholines flotation agent in potassium chloride has no flotation effect on potassium nitrate and ammonium chloride.
