Preparation method of high-activity calcium hydroxide
The invention relates to a preparation method of high-activity calcium hydroxide. According to the preparation method of the high-activity calcium hydroxide provided by the invention, the calcium hydroxide with high desulfurization efficiency is obtained by controlling the curing condition in the slaking process of the quick lime. Furthermore, according to the method disclosed by the invention, the desulfurization efficiency of the prepared calcium hydroxide is further improved by means of reasonably using an additive, controlling the water-cement ratio, adjusting the dosage of the additive and the like. The invention also provides the calcium hydroxide obtained by the method disclosed by the invention, and application of the calcium hydroxide in dry flue gas purification.
本发明提供了一种高活性氢氧化钙的制备方法，通过在生石灰的消化过程中控制熟化条件，获得了高脱硫效率的氢氧化钙。进一步地，本发明的方法通过合理使用添加剂、控制水灰比、调整添加剂用量等手段，进一步提高了制备得到的氢氧化钙的脱硫效率。本发明还提供了由本发明的方法获得的氢氧化钙，以及其在干法烟气净化中的用途。
