技术介绍
裂解炉法炽热钢渣热焖裂解工艺是温度高达1000℃以上的炽热钢渣低碳、环保、高效利用的最新技术,其工艺原理是将炽热钢渣倾倒入钢渣裂解炉中,在钢渣裂解炉中炽热钢渣自上而下先后经历蒸汽浴冷、喷雾冷却、热焖裂解、余热回收等过程。在蒸汽浴冷带,新倾倒入裂解炉中的温度高达1000℃以上的炽热钢渣被来自喷雾冷却带的低温饱和蒸汽浴冷,钢渣温度由1000℃以上急速降低到800℃以下,钢渣在内外温差应力的作用下得到初步破碎;在喷雾冷却带,喷头自上而下地向温度在800℃以下的中温钢渣表面雾化喷水,使钢渣温度进一步降低,与此同时钢渣中的f-CaO和f-MgO发生剧烈的水化反应生成Ca(OH)2和Mg(OH)2产生体积膨胀,膨胀应力使钢渣得到进一步破碎;在热焖裂解带,钢渣被喷头喷下的雾化水继续冷却至80℃以下,其中的f-CaO和f-MgO继续水化膨胀而使钢渣得到完全裂解。在炽热钢渣自上而下经历蒸汽浴冷带、喷雾冷却带和热焖裂解带的过程中,雾化喷入的水被加热汽化,蒸汽自下而上经过热焖裂解带、喷雾冷却带和蒸汽浴冷带,最后由炉顶排出,并被导入低温低压饱和蒸汽热能回收系统,从而实现炽热钢渣显热的回收利用。由上可见,对钢渣裂解炉炉盖的基本要求是能够可靠地承载炉盖自身的重量,并且不受炽热钢渣从渣罐倾倒入钢渣裂解炉时产生的振动和冲击的影响;炉盖本身具有较强的耐热性能,以使其在受到炽热钢渣长期高温热幅射的情况下仍能保持完好;炉盖要能将炽热钢渣的幅射热转换利用;炉盖还应具有良好的密封性能,以不使空气进入 ...
