Preparation process of calcium oxide for industrial ceramics
The invention provides a preparation process of calcium oxide for industrial ceramics, and relates to the technical field of calcium oxide preparation. The preparation process of the calcium oxide for the industrial ceramics comprises the following specific steps: S1, firstly putting blocky limestone into cleaning equipment for cleaning, and then putting the blocky limestone into drying equipment for drying treatment; s2, the dried blocky limestone is put into a grinding machine to be ground, after grinding is completed, a sieve plate is used for screening, and limestone particles are obtained; s3, putting the limestone particles into a calcining furnace, then putting the modified hydrotalcite, and separating the limestone particles from the modified hydrotalcite. By adding the modified hydrotalcite into the calcining furnace, the reduction of carbon dioxide generated during limestone calcining is facilitated, the influence of carbon dioxide on the environment is reduced, and by adding the pore-forming agent in the preparation process of the modified hydrotalcite, the contact area of the modified hydrotalcite and carbon dioxide is increased, and the improvement of the adsorption efficiency of carbon dioxide is facilitated.
本发明提供一种工业陶瓷用氧化钙制备工艺，涉及氧化钙制备技术领域。该工业陶瓷用氧化钙制备工艺，包括以下具体步骤：S1、首先将块状石灰石放入清洗设备内进行清洗，清洗完成后放入干燥设备内进行干燥处理；S2、将干燥后的块状石灰石放入研磨机内进行研磨，研磨完成后使用筛板进行筛分，并且得到石灰石颗粒；S3、将石灰石颗粒放入煅烧炉内，之后放入改性水滑石，并且石灰石颗粒与改性水滑石分隔开。通过在煅烧炉的内部添加改性水滑石，有利于降低石灰石煅烧时产生的二氧化碳，降低二氧化碳对环境的影响，并且改性水滑石在制备的过程中通过添加造孔剂，提高了改性水滑石与二氧化碳的接触面积，有利于提高二氧化碳的吸附效率。
