Description

高炉冲渣蒸汽回收系统
技术领域
本实用新型涉及排放蒸汽的回收利用，尤其涉及冶金行业高炉冲渣蒸汽回收系统。
背景技术
高炉炼铁工艺中，产生1400度-1500度的高温炉渣，炉渣在高炉炉渣粒化装置中进行水淬冲渣，产生冲渣水的同时会生成大量的蒸汽，这部分蒸汽经过烟囱排到大气中，既造成了能源的浪费，又对环境造成热污染。
发明内容
为了解决上述技术问题，本实用新型提供了一种高炉冲渣蒸汽回收系统，充分有效地回收利用冲渣蒸汽的热量，减少热污染。
为达到上述目的，本实用新型采取以下技术方案。
高炉冲渣蒸汽回收系统由管壳式换热器、引风机、支架、增压泵、热用户低温管道A、热用户低温管道B、热用户高温管道和热用户组成，其中，管壳式换热器由多根列管组成，列管构成管壳式换热器的管程，列管之间的空隙构成管壳式换热器的壳程；管壳式换热器置放在高炉炉渣粒化装置内部上方，并通过支架固定，支架一侧连接管壳式换热器、另一侧连接高炉炉渣粒化装置内壁，引风机安装在管壳式换热器最上方，增压泵的入口通过热用户低温管道A和热用户相连、出口通过热用户低温管道B和管壳式换热器入口相连，管壳式换热器出口通过热用户高温管道和热用户相连。
本实用新型提供的高炉冲渣蒸汽回收系统，通过热用户用水和冲渣蒸汽在管壳式换热器中进行热量交换，充分有效地回收了冲渣蒸汽的热量，减少热污染的排放，并将冲渣蒸汽液化后的冷凝水循环利用，节约水资源，同时减少加热热用户用水所需要的资源，起到节能减排的作用。 
附图说明
图1为本实用新型的高炉冲渣蒸汽回收系统示意图。
图中所示：1、高炉炉渣粒化装置；2、引风机；3、支架；41、热用户低温管道A；42、热用户低温管道B；5、增压泵：6、热用户；7、管壳式换热器；8、列管；9、壳程；10、热用户高温管道。
具体实施方式
下面结合附图和实施例对本实用新型进行详细的描述。
如图1所示，高炉冲渣蒸汽回收系统由管壳式换热器7、引风机2、支架3、增压泵5、热用户低温管道A41、热用户低温管道B42、热用户高温管道10和热用户6组成，其中，管壳式换热器7由多根列管8组成，列管8构成管壳式换热器7的管程，列管8之间的空隙构成管壳式换热器7的壳程9；管壳式换热器7置放在高炉炉渣粒化装置1内部上方，并通过支架3固定，支架3一侧连接管壳式换热器7、另一侧连接高炉炉渣粒化装置1内壁，引风机2安装在管壳式换热器7最上方，增压泵5的入口通过热用户低温管道A41和热用户6相连、出口通过热用户低温管道B42和管壳式换热器7入口相连，管壳式换热器7出口通过热用户高温管道10和热用户6相连。
冲渣蒸汽通过自身蒸发及引风机2的作用，进入管壳式换热器7的列管8，即冲渣蒸汽进入管程，热用户6使用过后的低温水经过热用户低温管道A41进入增压泵5加压、再通过热用户低温管道B42进入管壳式换热器7的壳程9，低温水和冲渣蒸汽进行热量交换后变成高温水，并通过热用户高温管道10回到热用户6，供热用户6循环使用；换热后的冲渣蒸汽液化成冷凝水，沿着列管8内壁流回高炉炉渣粒化装置1底部，汇到用于冲渣的冲渣水中以循环使用。
需要指出的是，以上所述只是本实用新型示意性的实施方式，并不是对本实用新型技术方案的限定，任何熟悉本领域的技术人员对本实用新型技术特征所做的等同变化或者相应改进，仍在本实用新型的保护范围之内。
