Continuous production method and system of calcium hydroxide with high whiteness and high specific surface area
The invention provides a continuous production method and system of calcium hydroxide with high whiteness and high specific surface area, and relates to the technical field of deep processing of limestone. The continuous production method comprises the following steps: step 1, continuously adding quick lime particles into an inlet of a primary digester, simultaneously continuously adding digestion water and an auxiliary agent into the inlet of the primary digester, and premixing and pre-digesting under a stirring condition; step 2, continuously introducing a material discharged from the primary digester into a secondary digester, continuously adding digestion water and an auxiliary agent at an inlet of the secondary digester, and stirring, digesting and aging; and 3, sequentially feeding the material discharged from the second-stage digester into a third-stage digester, a fourth-stage digester and a fifth-stage digester for digestion and aging, and grading by a grading machine to obtain the product. The method not only can be used for continuously preparing calcium hydroxide with high whiteness and high specific surface area, but also has the characteristics of simple process, short time consumption, remarkable effect, low energy consumption and the like, is already applied to actual production, and has a good use effect.
本发明提供了一种高白度、高比表面积氢氧化钙的连续生产方法和系统，涉及石灰石深加工技术领域。该连续生产方法包括如下步骤：步骤一：将生石灰颗粒连续加入到一级消化器的入口中，同时向一级消化器入口处连续加入消化用水以及助剂，搅拌条件下进行预混和预消化；步骤二：将一级消化器出料连续导入到二级消化器中，在二级消化器的入口处连续加入消化用水以及助剂，搅拌消化陈化；步骤三：二级消化器的出料依次进入三级、四级和五级消化器中消化陈化，经分级机分级后得到产品。该方法不仅能够连续制备高白度和高比表面积的氢氧化钙，而且还可以实现具有工艺简洁、耗时短、效果显著、能耗低等特点，并已在实际生产中得到应用，使用效果良好。
