氟硅酸输送管堵塞原因和改进措施

Causes of Blockage of Fluorosilicic acid Delivery Pipe and improvement Measures

为减缓氟硅酸输送管道硅胶沉积结垢,避免管道堵塞影响氟硅酸输送。针对湿法磷酸生产过程副产物氟硅酸输送管道易结垢堵塞问题,对氟硅酸输送过程中的流动形式、形态等进行了分析研究,并通过对输送流程改造,使用集中输送的方法大大降低了输送管结垢堵塞问题。

In order to slow down the silica gel deposition and fouling in the fluorosilicic acid transportation pipeline,and avoid the pipeline blockage to affect the fluorosilicic acid transportation. Aiming at the problem of easy fouling and clogging of the by-product fluorosilicic acid transportation pipeline during the production of wet-process phosphoric acid,this paper analyzes and studies the flow form and morphology of the fluorosilicic acid transportation process,and adopts the method of centralized transportation through the transformation of the transportation process. Greatly reduce the problem of fouling and clogging of the conveying pipe.
