阶梯形活性石灰炉制造技术

本发明专利技术公开了一种阶梯形活性石灰炉，它由预热带、煅烧带、冷却带三部分组成一体，其煅烧带采用燃烧器向炉内供热，煅烧带由至少四级台阶组成上宽下窄的煅烧腔体，每个台阶上安装一排连接外部操作控制装置的推杆。本发明专利技术的采用减少了石灰的硫含量和杂质含量，有效的保证了石灰石的煅烧质量；操作上可自动控制，也可人工控制。热效率高，炉壳温度可控制在８０℃以内。同规模的石灰竖炉中，阶梯形活性石灰炉的投资仅占回转窑和引进竖窑投资的二分之一。成品灰的活性度和生过烧率与回转窑和国外引进竖窑的指标相当；能源消耗较国内各种竖窑和回转窑低，维修简单，维护费用较少。

Stepped activated lime furnace

The invention discloses a ladder shaped active lime furnace, which is composed of a preheating zone, a calcining zone and a cooling zone is composed of three parts, the calcining zone by heating furnace burner, the calcination zone by at least four steps on the wide and narrow cavity composed of calcination, a row is connected with the external operation push rod control device installation each step. The adoption of the invention reduces the sulfur content and the impurity content of the lime, effectively ensures the calcination quality of the limestone and can be automatically controlled or artificially controlled on the operation. The heat efficiency is high, and the shell temperature can be controlled within 80 degrees. With the size of the lime shaft furnace, ladder shaped active lime furnace investment accounted for only the rotary kiln and the imported kiln investment 1/2. Ash activity index of the products and the fresh overburning rate and rotary kiln and shaft kiln is introduced; the energy consumption is low and the domestic various kiln kiln, simple maintenance, maintenance costs less.
