Production process of high-activity desulfurizer slaked lime
The invention relates to the technical field of flue gas desulfurizers, in particular to a production process of high-activity desulfurizer slaked lime, which comprises the following steps: step 1, mechanically crushing a quick lime block to obtain a quick lime particle raw material with the particle size of 2-10mm; step 2, mixing and grinding the quick lime particle raw material and calcium hydroxide to prepare an ash material with the particle size of 600-800 meshes, and the calcium hydroxide accounts for 10-30%; step 3, carrying out digestion treatment on the lime material, digestion water and a modifier to obtain lime slurry; step 4, carrying out impurity removal and separation treatment on the lime slurry; and 5, carrying out flash evaporation drying on the lime slurry subjected to impurity removal and separation so as to obtain slaked lime powder with a desulfurization function. According to the production process, the flue gas purification effect of the slaked lime absorbent is effectively improved; the prepared slaked lime absorbent is high in purity, large in specific surface area, rich in pores and small in particle size, namely excellent in comprehensive performance and high in activity, and has an ideal flue gas purification effect.
本发明涉及烟气脱硫剂技术领域，具体涉及一种高活性脱硫剂消石灰生产工艺，其包括如下步骤：步骤一、对生石灰块进行机械破碎以得到粒径2至10mm的生石灰颗粒原料；步骤二、将生石灰颗粒原料与氢氧化钙混合研磨，制得粒径达到为600‑800目的灰料，并且氢氧化钙占比为10％至30％；步骤三、将灰料与消化水及改性剂进行消化处理得到石灰浆料；步骤四、对石灰浆料进行除杂、分离处理；步骤五、对除杂、分离后的石灰浆料进行闪蒸干燥，并得到具有脱硫功能的消石灰粉体。该生产工艺有效提升消石灰吸收剂的烟气净化效果；所制备的消石灰吸收剂的纯度高、比表面积大、孔隙丰富且粒度小，即综合性能优异活性高，具备理想的烟气净化效果。
