串联法氧化铝生产中的合流脱硅

Confluence desilication of alumina production in series process

合流脱硅是简化联合法生产流程、降低能耗的有效措施。因此,国内外业界做了大量卓有成效的工作。串联法的工艺特点,更宜于采用合流脱硅。试验结果表明,串联法采用常压合流脱硅流程可以达到所需要的硅量指数。文中还对合流脱硅的硅量指数、合流点、合流脱硅温度、赤泥种子和添加石灰乳等问题进行了讨论。

Confluence desilication is an effective measure which can simplify the combination process and reduce energy of the process. So the experts in the world did highly effective work on it. The characters of series process are suitable for the confluence desilication. The results of test show that atmospheric confluence desilieation in the series process can approach the required siliceous modulus. The author also discuss the confluence desilication＇ s siliceous modulus confluerice temperature,red mud seed and the addition of lime milk.
