In the wet-process phosphoric acid production from the Hubei phosphate ore, one of the bothersome problems is that potassium fluosilicate and sodium fluosilicate scales are liable to form on the filtration system owing to its high potassium and sodium content, which greatly restrains the application of Hubei phosphate ore.
本文首先采用人工冷却系统模拟湿法磷酸生产的真空过滤系统冷却过程,研究垢物的析出规律,实验结果得知:垢物的主要成分为氟硅酸钠和氟硅酸钾,氟硅酸钠首先析出,结构致密,其次是氟硅酸钾,最后是二水硫酸钙,氟硅酸钠对氟硅酸钾有很强的结晶诱导作用;然后在三种生产中常用的不同的材质钼二钛、聚氯乙烯和聚四氟乙烯表面进行结垢试验,发现聚四氟乙烯表面最不易结垢,而在钼二钛表面最易结垢。

It is found that the fouling rate is lowered during subcooled fow boiling by carrying gas injection, and the influence of carrying gas injection on fouling of convective heat transfer is more obvious than that of subcooled flow boiling; morphology of CaCO〓 crystallization fouling exhibits self-similarity and the fractal dimensions of CaCO〓 crystallization fouling are determined from the gray scale distribution of the SEM images by box-dimension method. The value of the crystallization fouling surface fractal dimensions reveals the complexity of the surface, and can be used as an import parameter for the investigation of influence of carrying gas injection on scale formation.
实验发现:引入载气,过冷流动沸腾结垢速率降低,但引入载气对过冷流动沸腾结垢速率的影响要弱于对对流传热结垢速率的影响;CaCO〓结晶垢具有统计自相似性,即分形特征;用盒子维法测定了CaCO〓结晶垢的分维值,分维值的大小反映了换热面上生成的结晶垢表面复杂程度,可用于描述引入载气对污垢的形成作用。

Reinjection is applied for sewage disposal in Daniudi gasfield. Sewage contains some sulfate ion. The main ion in formation water with high salinity includes K, Na, Ca, Mg and Ba. So reinjected sewage combining with original formation water will generate scaling, And the scaling type is mainly sulfate scale.
中文摘要:大牛地气田对污水处理采用回注方法,污水中含有一定量的硫酸根离子,而地层水中也有很高的矿化度,主要离子为钾、钠、钙、镁、钡,因此回注污水与原地层水相混,会产生结垢现象,结垢类型主要为硫酸盐垢。
