Energy-saving system combining dead-burnt magnesium oxide and light-burnt magnesium oxide and use method of energy-saving system
The invention discloses an energy-saving system combining dead-burnt magnesium oxide and light-burnt magnesium oxide and a using method.The energy-saving system comprises a light-burnt magnesium oxide unit, the light-burnt magnesium oxide unit comprises a suspension preheater, an out-of-kiln predecomposition furnace and a suspension cooler, a top outlet of the out-of-kiln predecomposition furnace is connected with an inlet of the suspension preheater, and a top outlet of the out-of-kiln predecomposition furnace is connected with an outlet of the suspension cooler; a bottom outlet of the out-kiln predecomposition furnace is connected with an outlet air pipe of the suspension cooler, and a blanking pipe of the suspension preheater is connected with an inlet of the suspension cooler; the magnesium oxide dead burning unit comprises a rotary kiln and a grate cooler, a branch pipe is arranged on the pre-decomposition furnace outside the kiln and connected with the rotary kiln, and an outlet of the rotary kiln is connected with an inlet of the grate cooler. According to the method, the light calcined magnesia can be independently prepared, the light calcined magnesia and the dead calcined magnesia can be simultaneously prepared, the two processes can be switched and selected as required, and the method has the characteristics of low energy consumption, low emission, high efficiency and the like.
本发明公开了一种重烧和轻烧氧化镁相结合的节能系统及使用方法，包括轻烧氧化镁单元，所述轻烧氧化镁单元包括悬浮预热器、窑外预分解炉和悬浮冷却器，窑外预分解炉的顶部出口与悬浮预热器的入口相连，窑外预分解炉的底部出口与悬浮冷却器的出口风管连接，悬浮预热器的下料管与悬浮冷却器的入口相连；重烧氧化镁单元，所述重烧氧化镁单元包括回转窑和篦冷机，在窑外预分解炉上设支管与回转窑连接，回转窑出口与篦冷机入口连接。本发明既可完成轻烧氧化镁的单独制备，也可满足轻烧氧化镁和重烧氧化镁的同时制备，两种工艺可根据需要切换选择，具有低能耗、低排放、高效率等特点。
