Gypsum calcination rotary kiln production line system
The invention relates to a gypsum calcining rotary kiln production line system which comprises a rotary kiln and a feeding system, the rotary kiln is provided with a drying section and a calcining section, and the gypsum calcining rotary kiln production line system further comprises a hot air generating system used for generating hot air. A rotary kiln heat insulation cover for hot air to enter so as to calcine gypsum raw materials in the rotary kiln is arranged on the rotary kiln and located on the outer side of the drying section and/or the outer side of the calcining section, and partition plates used for dividing the interior of the rotary kiln heat insulation cover into two or more heating cavities are arranged in the rotary kiln heat insulation cover. And a hot air pipeline is arranged between each heating chamber and the hot air generating system. Compared with the prior art, according to the characteristic that the calcination temperature of the desulfurized gypsum is sensitive, the whole process temperature section is independently controlled in a partitioned mode, on one hand, the temperature environment needed by the desulfurized gypsum in each calcination stage can be achieved, on the other hand, energy consumption is low, and energy is saved by about 20% compared with a traditional process through temperature adjustment and control of all the regions; the phenomenon of light burning or overburning is avoided, and the quality of finished gypsum is guaranteed to the maximum extent.
本发明涉及石膏煅烧回转窑生产线系统，包括回转窑和送料系统，回转窑具有烘干段、煅烧段，石膏煅烧回转窑生产线系统还包括用于产生热风的热风发生系统，回转窑上于烘干段外侧和/或煅烧段外侧设有供热风进入以对回转窑内的石膏原料进行煅烧的回转窑隔热罩，回转窑隔热罩内设有用于在回转窑隔热罩内分隔出两个以上加热腔室的隔板，各加热腔室与热风发生系统之间分别设有热风管道。相比于现有技术，针对脱硫石膏的煅烧温度敏感的特性，整个工艺温度段实行分区单独控制，一方面能够做到脱硫石膏在煅烧各个阶段所需要的温度环境，另一方面通过各个区温度调节控制，能耗低、较传统的工艺节能20%左右，不出现轻烧或过烧现象，最大化保证成品石膏品质。
