Preparation process of calcium hydroxide and calcium hydroxide product
The invention provides a preparation process of calcium hydroxide and a calcium hydroxide product, and relates to the technical field of inorganic material processing. According to the manufacturing process, calcium carbonate raw ore is calcined into calcium oxide powder, the calcium oxide powder is made to float in the space in a spraying mode, at the moment, atomized water and the calcium oxide powder are mixed in the same space and digested, then the digested calcium hydroxide powder can be settled after digestion, and the calcium oxide powder is recycled. And the calcium hydroxide powder with the required particle size is selected through winnowing. In the technical process, the atomization mode can enable the contact area of water and the calcium oxide powder to be larger, the digestion effect is better, meanwhile, the period is shorter, the water consumption and the energy consumption are lower, and the manufacturing cost is lower. Compared with the prior art, the manufacturing process (the whole process from calcium carbonate raw ore to calcium hydroxide preparation) has the advantages that the coal consumption (converted into the coal consumption when coal is not used) and the water consumption can be saved, the period is greatly shortened, and meanwhile, the cost can be saved by about 30%.
本发明提出一种氢氧化钙的制作工艺及氢氧化钙产品,涉及无机材料加工技术领域。该制作工艺将碳酸钙原矿石煅烧为氧化钙粉末,并以喷洒的方式使其漂浮于空间内,此时,以雾化后的水与其在同一空间内混合,并进行消化,然后经过消化后,可使得消化而得的氢氧化钙粉末沉降下来,再以风选选出所需粒径的氢氧化钙粉末。在上述工艺过程中,雾化的方式不仅能够使得水与氧化钙粉末的接触面积较大,消化效果较好的同时周期较短,水耗量以及能耗量较低,制作成本较低。与现有技术相比,该制作工艺(自碳酸钙原矿石到制成氢氧化钙的整个过程)可节省用煤量(不用煤时,折算为用煤量)和耗水量,周期大大缩短,同时成本可节约30%左右。
