The invention relates to a lime production device which comprises a lime kiln system and a coal gasification system. The coal gasification system comprises a vertical gasifier, a pulverized coal distributor, a fuel heat accumulator, an air heat accumulator, an induced draft fan and a dust remover. A lime kiln of the lime kiln system is a beam type lime kiln or a dividing wall lime rotary kiln. The vertical gasifier is provided with a combustion chamber, a hearth, a gas chamber and a slag collecting chamber, and the hearth is provided with a tungsten pipe. The upper part of the tungsten pipe is communicated with the gas chamber, and the lower part of the tungsten pipe is connected with the slag collecting chamber. One path of an outlet of the gas chamber is connected to the lime kiln system through an evaporator, a dust remover and an induced draft fan, and the other path is connected to the gas burner through a fuel heat accumulator. The air blower is connected to the gas burner through the air heat accumulator. The coal gas generated by the coal gasification system is used for calcining and producing the lime, the carried heat is used for generating the steam, and the flue gas is used for preheating the fuel gas and the combustion-supporting gas, so that the energy consumption of lime production is reduced, and the production cost is reduced.
本发明涉及一种石灰生产装置，包括石灰窑系统和煤气化系统。煤气化系统包括立式气化炉、煤粉布料器、燃料蓄热器、空气蓄热器、引风机和除尘器。石灰窑系统的石灰窑为梁式石灰窑或间壁石灰回转窑。立式气化炉设有燃烧室、炉膛、煤气室和熔渣收集室，炉膛设有钨管。煤粉仓通过煤粉布料器连接到钨管，钨管上部与煤气室连通，下部与熔渣收集室连接。煤气室出口通过蒸发器、除尘器和引风机一路连接到石灰窑系统，一路经燃料蓄热器连接到燃气烧嘴。鼓风机通过空气蓄热器连接到燃气烧嘴。本发明利用煤气化系统产生的煤气煅烧生产石灰，同时利用携带的热量发生蒸汽，利用烟气为燃料气和助燃气体预热，减少了石灰生产的能耗，降低了生产成本。
