Description

Technical Field

[0001] The utility model relates to the technical field of alumina production, in particular to cooling equipment for the production and preparation of alumina. Background Art

[0002] Alumina is an inorganic substance with the chemical formula A1203. It is a high-hardness compound with a melting point of 2054°C and a boiling point of 2980°C. It is an ionized crystal that can be ionized at high temperatures and is often used to manufacture refractory materials. At present, the final product alumina needs to be cooled and cooled in the production and preparation of alumina. After being cooled from the roasting furnace through the cyclone cooling system, the temperature of the alumina is usually above 250°C and cannot be directly sent to the storage and transportation system. For the safety of equipment and personnel, the alumina cooled by the cyclone cooling system needs to be cooled again in the cooler. The existing simple cooling method relies on increasing the cooling area of ​​the cooler to meet the requirements of the process conditions. For factories with limited land use, land utilization is particularly important. As the overall production capacity of the roasting furnace increases, the area required for the cooler increases, and the volume and weight of the equipment also increase. This makes it difficult to build a cooler for factories with limited land use. Therefore, a cooling equipment for alumina production and preparation is proposed to address the above problems.
