Gas burning type active lime kiln
The invention relates to a gas burning type active lime kiln, and belongs to the technical field of metallurgical equipment. An existing active lime kiln type structure is changed, and a shaft kiln is divided into a preheating part, a limestone transfer and air heat exchange part and a mechanical gas shaft kiln part. According to a disclosed method, lime can be quantitatively calcined, and the preheating temperature of limestone in the preheating kiln and the calcining temperature in the calcining kiln are accurately controlled; the activity degree of the produced lime is high and is generally 390-460; and the overburning rate can be reduced, and the energy-saving effect is achieved.
本发明涉及一种气烧型活性石灰窑，属于冶金设备技术领域。本发明改变了现有活性石灰窑型结构，将竖窑分为预热、石灰石转移和空气热交换、机械化燃气竖窑三个部分。该方法可以定量煅烧石灰，精准控制预热窑内石灰石的预热温度和煅烧窑内的煅烧温度；生产的石灰活性度高，一般在390~460；可减少生过烧率，实现节能创效。
