Vertical preheater: ① different daily output for active lime scale, pre-heater use to apply different scale production of square, circle, polygon vertical preheater, Tuitou amount determined according to the size of the warm-up area, covering Tuitou reasonable area; ② use with low pressure drop beams preheater, reduce flue gas pressure loss in the preheater, reducing exhaust device power consumption. To the high-temperature heat from the kiln flue gas directly through the material layer with gravel full heat exchange, East Taiwan kiln fan, preheat temperature up to 800-900 ℃, lime kiln fan testing, part of stones to give decomposition, preheat Decomposition while effectively reducing exhaust gas temperature; ③ preheater kiln with hydraulic pusher to feed, reliable equipment operation; ④ preheater top silo level meter control features to ensure highly stable preheater material layer; ⑤ In addition to the top of the preheater uses hanging bricks, the other parts are made of refractory castable, low brick, masonry simple; ⑥ preheater small sports equipment, small equipment maintenance. First, the structure and type of activity of a lime kiln, lime kiln active lime kiln structure activity consists of the kiln, the feeding device, feeding device, discharging device, automated instrumentation control and dust removal devices and other components. 2, active lime kiln type: different forms of lime kiln, its structure and calcined forms differ, the process is basically the same.
