Production device and production method for preparing caustic burned magnesia from magnesite
The invention discloses a production device and a production method for preparing caustic burned magnesia from magnesite, and belongs to the field of chemical production devices. According to the production device, a storage box of a feeding assembly in the device is communicated with a feeding port of a first air blower through a conveying pipeline, and a preheating assembly connected with the storage box comprises a plurality of preheating heat exchange furnaces which are sequentially connected in series along the material flow direction; a combustor nozzle and a combustion gas inlet are arranged at the lower part of a heating decomposition furnace connected with the preheating assembly; the combustion gas inlet is connected with a second air blower, a feeding port in the upper end of the heating decomposition furnace is communicated with a discharging port of a Nth preheating heat exchange furnace of the preheating assembly through a feeding pipe, and a discharging port in the lowerend of the heating decomposition furnace is communicated with a waste heat treatment assembly through a discharging pipe; the waste heat treatment assembly comprises a plurality of waste heat exchange furnaces which are sequentially connected in series in the material flow direction. In the calcining process, heat energy is fully utilized, energy can be fully saved, and the caustic burned magnesia prepared by adopting the device is uniform in particle and high in activity.
