一种带匀流盖的钉头管及具有其的加热炉
本专利技术涉及加热炉
,特别是涉及一种带匀流盖的钉头管及具有其的加热炉。
技术介绍
加热炉是石油化工中的龙头,通常包括常压炉、减压炉、制氢炉、重整炉、焦化炉、转化炉及裂解炉等。管式加热炉的作用于是将介质(油料或气体)加热至工艺所需的温度。加热炉的炉体的四面由高大的炉墙围成炉膛,炉墙由工字钢等型钢钢架上铺焊钢板,钢板上分布焊接保温钉,在保温钉之间浇铸入隔热和耐磨材料。图1是组成加热炉炉体的一块换热模块的横截面示意图,炉墙1上安装的支架2支持着管板3,钉头管孔4上穿过钉头管(为增加换热效率,钉头管多为钉头管5),多个钉头管5的端部通过弯头窜联连接组成盘管,盘管和弯头箱等主要零部件组成换热模块,换热模块叠装后底部安装燃烧器,顶部安装烟囱,组成加热炉的炉体。钉头管5内流过的是需要加热的油料,见图1钉头管5外面在炉膛内从下往上箭头所示流过的是高温烟气或热风,其热量通过管壁传给钉头管5内的油料或其它介质。传统加热炉对炉体结构中存在两个尚未解决的技术难题,一方面难题是因为钉头管外表面整体上从烟气获取热量的能力满足不了钉头管内表面对油品 ...
