The invention relates to a mineral smelting device which comprises a gasification heating furnace, a rotary kiln, a vertical lime kiln, a Kelaipu unit and a tail gas treatment system. A circulating gas outlet of the gasification heating furnace is divided into two paths, one path is connected to a circulating gas inlet of the rotary kiln, and the other path is connected to a combustion beam or a gas inlet beam of the vertical lime kiln. A tail gas outlet of the rotary kiln is divided into two paths, one path is connected to the tail gas treatment system, and the other path is connected to a tail gas ejection inlet of an ejector of the gasification heating furnace. A fume outlet at the top of the vertical lime kiln is divided into two paths, one path is connected to the tail gas treatment system, and the other path is connected to an ejection gas inlet of the ejector through a circulating pump. According to the invention, lime is produced by combining the gasification heating furnace, the rotary kiln and the vertical lime kiln; calcium carbide, reduced iron, silicon iron, metal magnesium and the like are co-produced; and the temperature of coal gasification is controlled by tail gascirculation so as to benefit for improving the heat energy utilization rate, reducing energy consumption, implementing zero emission of carbon dioxide and meanwhile, producing various byproducts.
本发明涉及一种矿物冶炼装置，包括气化加热炉、回转窑、竖式石灰窑、柯来浦单元和尾气处理系统。气化加热炉的循环气体出口分为两路，一路连接到回转窑的循环气体入口，另一路连接到竖式石灰窑的燃烧梁或进气梁。回转窑的尾气出口分为两路，一路连接到尾气处理系统，另一路连接到气化加热炉引射器的尾气引射入口。竖式石灰窑顶的烟气出口分为两路，一路连接到尾气处理系统，一路通过循环泵连接到引射器的引射气进口。本发明通过气化加热炉、回转窑和竖式石灰窑相结合生产石灰，联产电石、还原铁、硅铁和金属镁等，利用尾气循环控制煤气化的温度，有利于提高热能利用率，降低能耗，实现二氧化碳的零排放，同时副产多种副产品。
