Interval heating type roasting lime kiln
The interval heating type roasting lime kiln comprises a furnace body, and the furnace body comprises a furnace base body, a plurality of material box sets arranged in the furnace base body and combustion chambers arranged on the two sides of each material box set; the material box set is composed of two material boxes and a partition wall arranged between the two material boxes. A plurality of guide plates are uniformly distributed in the combustion chamber; a plurality of feeding hoppers are arranged at the top of the furnace base body, and a plurality of discharging hoppers are arranged at the bottom of the furnace base body; a plurality of preheated air inlet transverse channels are formed at the bottom of the side wall of the furnace base body, and a plurality of gas pipelines are arranged in the middle; flues are formed in the two side walls of the furnace base body, and a plurality of vent holes communicated with the flues are formed in the combustion chamber. According to the interval heating type roasting lime kiln, a heat carrier does not make direct contact with heated materials, it is guaranteed that the temperature of the lime kiln is uniform, decomposition of limestone is facilitated, and the activity of the lime is improved; and meanwhile, energy conservation and recovery of high-purity carbon dioxide are realized.
本发明公开了一种间隔加热式焙烧石灰窑，包括炉体，炉体包括炉基体，设置于炉基体内部的多组料箱组以及设置于每组料箱组两侧的燃烧室；料箱组由两个料箱以及设置于两个料箱间的隔墙组成；燃烧室内部均布多个导向板；炉基体顶部设置多个加料斗，底部设置多个出料斗，加料斗和出料斗均与料箱连通；炉基体侧壁的底部形成多个预热空气进气横道，中部设置多个燃气管道；炉基体两侧壁内部形成烟道，燃烧室形成多个与烟道连通的通气孔。本发明提供了一种间隔加热式焙烧石灰窑，热量的载体与被加热的物料不直接接触，既保证了石灰窑温度均匀有利于石灰石的分解，提高石灰的活度；同时实现节能，以及回收高纯度高纯度二氧化碳的回收。
