System for preparing anhydrous calcium sulfate by calcining gypsum
The invention discloses a system for preparing anhydrous calcium sulfate by calcining gypsum, which comprises a preheating unit, a calcining unit and a cooling unit, the preheating unit is connected with the calcining unit, the calcining unit is connected with the cooling unit, and a gypsum material enters the calcining unit to prepare anhydrous calcium sulfate after passing through the preheating unit. And the calcining unit and the cooling unit exchange heat bidirectionally to obtain cooled anhydrous calcium sulfate. The main calcining furnace, the auxiliary calcining furnace, the dryer, the first-stage preheater, the second-stage preheater and the four coolers are communicated with one another, so that high-temperature flue gas generated by calcining of the main calcining furnace can be fully recycled, a large amount of heat loss is avoided, energy is saved, and the production cost is reduced. By arranging the cooling unit, the gypsum material exchanges heat with cold air in a suspended state in the four coolers after being calcined, so that the temperature of anhydrous calcium sulfate output by the system is not high, and the anhydrous calcium sulfate is convenient to collect.
本发明公开一种石膏煅烧制备无水硫酸钙的系统，包括预热单元、煅烧单元和冷却单元，所述预热单元与煅烧单元连接，煅烧单元与冷却单元连接，石膏物料经过预热单元后进到煅烧单元制备无水硫酸钙，煅烧单元与冷却单元双向换热得到冷却后的无水硫酸钙。本发明煅烧主炉、煅烧副炉、干燥器、一级预热器、二级预热器和四个冷却器之间互相连通，使煅烧主炉煅烧产生的高温烟气能充分回收利用，避免了大量的热量损失，节约了能源，降低生产成本。通过设置的冷却单元，使石膏物料在煅烧加工完成后在四个冷却器中分别与冷风以悬浮状态换热，使系统输出的无水硫酸钙温度不高，便于收集。
