The utility model discloses an environment-friendly gas fired double tube pair burning lime kiln, including an outer kiln body, an inner kiln body set in the outer kiln body, a calcining chamber between the outer kiln body and the inner kiln body, an outer calcining ring arranged through the outer kiln body, an internal calcining ring throughout the inner kiln body, and a calcined calcining chamber at the lower end of the calcining chamber. The falling ash tray of the port and the ash tray are connected with the falling ash driving device; the upper temperature of the outer kiln body is high, the material will be preheated first when the material falls, the material goes into the calcining ring device and the inner calcining ring device, and the calcining is in the calcining stage, and the calcining is natural when the outer calcining ring device and the inner calcining ring are marching. After cooling, the lime activity of the production has been greatly improved. The limestone can be controlled by the falling ash tray, the limestone can be controlled outward, the limestone is transported outward, the ash tray is closed by the ash driving device, the closed ash is realized, the dust is effectively controlled, and the burning gas is calcined in the calcining process, and no air pollution will be produced.

技术介绍
石灰是碳酸盐(主要是碳酸钙CaCO3)矿物经过一定温度的煅烧,放出二氧化碳(CO2)后形成的氧化物(主要成分是:CaO)称为生石灰,俗称:石灰。按成分分类:钙质石灰(MgO%≤5%)、镁质石灰(MgO%>5%),在钢铁冶金行业,因石灰有很强的脱磷、脱硫能力又不危害炉衬,所以炼钢中添加石灰造渣,石灰是炼钢生产的主要造渣原料,接触石灰的脱硫功能,很多企业采用石灰进行烟气脱硫处理,因此我国石灰用量巨大。石灰的生产工艺中需要经过煅烧工艺,该工艺主要在窑炉中完成,由于石灰需求量大,因此形成了很多小微规模的石灰窑,进行石灰煅烧加工。部分微小规模石灰生产厂家环保意识差,再加上资金少,没有设置专门的环保设备,因此对大气环境形成严重污染,国家和地方政府相继出台了一系列整治土烧窑的政策和法规,要求使用现代新技术石灰窑。所谓现代新技术石灰窑就是具有环保、节能功能和机械化、自动化程度较高的现代化石灰窑。但是,上述石灰窑存在结构复杂、运行成本高、对燃料适应性差等问题,基于上述因素,有必 ...
