The invention relates to a production device for co-production of calcium carbide and lime. The device comprises a fixed calcium carbide furnace, a vertical fixed gasifier and a dividing wall lime rotary kiln. The fixed calcium carbide furnace is provided with a tail gas chamber, a hearth and a calcium carbide collecting chamber, the vertical fixed gasifier is provided with a gas chamber, a hearth and a slag collecting chamber, and the dividing wall lime rotary kiln is provided with a kiln chamber and a lime calcining space. The fixed calcium carbide furnace and the vertical fixed gasifier are connected into a whole. The gas chamber and the exhaust gas chamber are connected to the gas burner through the kiln, pulverized coal preheater, a No. 2 dust collector, a No. 2 induced draft fan and a gas regenerator. The flue gas of the vertical fixed gasifier is preheated by coal gas and air, and then is subjected to dust removal and nitrogen separation, one path is connected to a pulverized coal distributor, and the other path is connected to a waste gas emission system. The flue gas residual heat generated in the calcium carbide production process is used for coal gasification and heating calcination of lime, the heat and combustible gas generated in calcium carbide production are fully utilized, the energy consumption of calcium carbide production is reduced, and the production cost is reduced.
本发明涉及一种电石联产石灰的生产装置，包括固定电石炉、立式固定气化炉和间壁石灰回转窑。固定电石炉设有尾气室、炉膛和电石收集室，立式固定气化炉设有煤气室、炉膛和熔渣收集室，间壁石灰回转窑设有窑膛和煅烧石灰空间。固定电石炉和立式固定气化炉连接为一体。煤气室和尾气室一同通过窑膛、煤粉预热器、2号除尘器、2号引风机和煤气蓄热炉连接到燃气烧嘴。立式固定气化炉的烟气为煤气和空气预热后经除尘和分离氮气后一路连接到煤粉布料器，一路连接到废气排放系统。本发明利用电石生产过程产生的烟气残余热量进行煤气化和加热煅烧石灰，充分利用了电石生产产生的热量和可燃性气体，减少了电石生产的能耗，降低了生产成本。
