Calcium oxide production device and production method
The invention discloses a calcium oxide production device and production method. According to the method, a calcining tower is used as a reaction device, industrial waste carbide slag is used as a rawmaterial, reasonable drying, preheating and calcining zone arrangement are carried out on equipment in the calcining tower, the material is subjected to preheating dehydration outside the tower and drying-presintering-calcining process treatment in the tower, a calcium oxide product with the purity of more than 85% is synthesized, and the product yield is more than 90%. High-temperature-resistantfluidized vibrating screens made of silicon carbide, ceramic and other materials are arranged in the calcining tower drying and pre-calcining treatment area so that the materials entering the calcining area can be in full contact with a heat source, and the ignition loss of the materials is increased; the device is simple in structure, small in occupied area and high in energy utilization efficiency, meanwhile, efficient cyclic utilization of the carbide slag is achieved, and industrial production is facilitated.
本发明公开了一种氧化钙生产装置及生产方法。该方法利用煅烧塔为反应装置，以工业废料电石渣为原料，通过在煅烧塔内对设备进行合理的干燥、预热、煅烧区设置，物料经塔外预热除水、塔内干燥—预烧—煅烧工艺处理，合成纯度＞85%的氧化钙产品，产品收率＞90%。其中，所述的煅烧塔干燥及预烧处理区均设有碳化硅、陶瓷等材质耐高温流化振动筛，可以保证进入煅烧区的物料与热源充分接触，提高物料的烧失量；本发明装置结构简单、占地面积小、能量利用效率高，同时实现了电石渣的高效循环利用，利于工业化生产。
