Smoke waste heat utilization type preheater of lime rotary kiln
The invention discloses a smoke waste heat utilization type preheater of a lime rotary kiln. The smoke waste heat utilization type preheater of the lime rotary kiln comprises a combustion chamber; the combustion chamber is composed of a guide cone and a suspended ceiling; preheating bins arranged at equal intervals are arranged on the circumferential outer wall of the combustion chamber, and a smoke exhaust pipe is arranged at the top of each preheating bin; a discharging groove is formed in the top of the position, on one side of each smoke exhaust pipe, of the corresponding preheating bin; a material guiding bin communicated with the rotary kiln is arranged below the guiding cone; a combustor is arranged on the suspended ceiling; and a combustion fan is installed on the combustor. The device has the beneficial effects that by-product gas generated by steelmaking is recovered, and then combusted and heated, in cooperation with flue gas generated during calcination in the rotary kiln, so that limestone in the preheating bins can be heated, the utilization efficiency of the by-product gas is improved, high-calorific-value fuel consumed during limestone calcination is reduced, and then the production cost is reduced.
本发明公开的一种石灰回转窑烟气余热利用式预热器,包括燃烧室,所述燃烧室由导向椎体和吊顶组成,所述燃烧室的周向外壁上设有等间距排列布置的预热仓,每个所述预热仓的顶部设有排烟管,所述排烟管一侧的预热仓顶部设有下料槽,所述导向椎体的下方设有与回转窑连通的导料仓,所述吊顶上设有燃烧器,所述燃烧器上安装有助燃风机。有益效果在于:通过对炼钢所产生的副产物煤气进行回收后燃烧加热,并配合回转窑内部煅烧时产生的烟气,能够对预热仓内部的石灰石进行加热,提升了副产物燃气的利用效率,减少了石灰石煅烧时所消耗的高热值燃料,进而降低生产成本。
