The invention discloses a method and a system for calcining dolomite in a heat accumulating type energy-saving double-hearth shaft kiln. The method comprises the following steps that a double-hearth shaft kiln and related auxiliary equipment are debugged, materials are prepared and charged, and a discharging device continuously operates in the process; ignition is conducted after charging is completed, the kiln with materials is dried, and in the kiln drying process, a feeding device and the discharging device are in a continuous running state; the production system starts calcination betweenthe ignition and the kiln drying, and comprises the steps of calcination, reversing, burdening, feeding, ash discharging and ash discharging, the burdening process is between reversing and calcination, the double-hearth shaft kiln conducts reversing while conducting calcination, a calcination kiln hearth is periodically adjusted to be an exhaust kiln hearth, and an original exhaust kiln hearth isadjusted to be a calcination kiln hearth, the feeding is conducted in the reversing process, and the ash discharging process and the reversing are conducted simultaneously; and ash is discharged to obtain a calcined dolomite product. According to the method, the phenomenon of non-uniform heat distribution in a calcining process is improved, the technological process of each link is optimized, andthe calcining yield and the product quality are improved.
本发明公开了一种蓄热式节能型双膛竖窑煅烧白云石的方法和系统，包括以下步骤：双膛竖窑及相关辅助设备调试、备料，装料，过程中卸料装置连续运转；装料完毕后点火，进行带料烘窑，烘窑过程中，进料和卸料装置处于连续运转状态；生产系统启动煅烧穿插于点火烘窑过程中，包括煅烧、换向、配料、加料、出灰、卸灰几个步骤，配料过程穿插于换向和煅烧之间，双膛竖窑边煅烧边换向，周期性的将煅烧窑膛调为排气窑膛，原排气窑膛调为煅烧窑膛；加料穿插在换向之中，卸灰的过程与换向同时进行；出灰，得到产品煅白料。该方法改善煅烧过程中热量分布不均匀的现象，优化各环节工艺流程，提高煅白合格率和产品质量的目标。
