The invention relates to a lime-calcium carbide joint production system and method. A device comprises a gasification heating furnace, a lime rotary kiln, a calcium carbide rotary kiln and a CO2 recovery device. The gasification heating furnace is of a rotary kiln structure and comprises a fuel nozzle, a circulating gas outlet, an ash outlet and an ejector. The circulating gas outlet of the gasification heating furnace is connected to the lime rotary kiln and the calcium carbide rotary kiln. The production process comprises the following steps: preheating a limestone raw material by lime tail gas of a lime rotary kiln, feeding one path to a CO2 recovery device to recover pure CO2, and feeding the other path to an inlet of a circulating pump; and enabling calcium carbide tail gas of the calcium carbide rotary kiln to enter the gasification heating furnace through the ejector to serve as gas burning materials. The gasification heating furnace, the calcium carbide rotary kiln and the lime rotary kiln are combined to produce calcium carbide and lime, high-temperature hot carrier gas obtained through coal gasification of the gasification heating furnace supplies heat to the calcium carbide rotary kiln and the lime rotary kiln, the fire coal heat energy utilization rate is increased, and fire coal consumption is reduced.
本发明涉及一种石灰‑电石联合生产系统和方法，装置包括气化加热炉、石灰回转窑、电石回转窑和CO2回收装置。气化加热炉为回转窑结构，包括燃料喷嘴、循环气体出口、灰渣出口和引射器。气化加热炉的循环气体出口一路连接到石灰回转窑，一路连接到电石回转窑。生产过程包括石灰回转窑的石灰尾气预热石灰石原料后一路到CO2回收装置回收纯净CO2，另一路到循环泵入口。电石回转窑的电石尾气经引射器进入气化加热炉作气体然料。本发明通过气化加热炉、电石回转窑和石灰回转窑相结合生产电石和石灰，气化加热炉煤气化得到的高温热载气向电石回转窑和石灰回转窑供热，提高了燃煤热能利用率，减少了燃煤消耗量。
