Description

一种用于干馏气热回收的管道
技术领域
本发明属于生物质处理技术领域，具体地，涉及一种用于干馏气热回收的管道。
背景技术
生物质能就是太阳能以化学能形式贮存在生物质中的能量形式，即以生物质为载体的能量。它直接或间接地来源于绿色植物的光合作用，可转化为常规的固态、液态和气态燃料，取之不尽、用之不竭，是一种可再生能源，同时也是唯一一种可再生的碳源。生物质能源技术是一种具有广阔发展前途的新能源技术。
发明内容
本发明的目的是提供一种用于干馏气热回收的管道。
本发明的目的通过以下技术方案来具体实现：
一种用于干馏气热回收的管道，包括内管、外管和保温层，所述内管为正方形，外管为圆管，内管中心和外管圆心重合，所述外管包裹聚氨酯管壳，聚氨酯管壳外包裹镀锌钢板。
进一步的，所述内管由耐高温钢制作而成；
所述外管为螺旋缝钢管；
所述聚氨酯管壳的厚度为100-150mm；
所述镀锌钢板的厚度为0.2-0.3mm。
干馏气经过内管，换热介质为水，从内管和外管之间的空间流过，干馏气和水逆流换热。
本发明具有以下有益效果：
本发明提供的用于干馏气热回收的管道，内管采用方形，提高了干馏气与介质水的换热面积，本管道适合于内管管径≥500mm管道。
附图说明
图1为本发明用于干馏气热回收的管道的结构图。
图中：1-内管；2-外管；3-聚氨酯管壳；4-镀锌钢板。
具体实施方式
如图1所示，本发明实施例所述用于干馏气热回收的管道，包括内管1、外管2和保温层3，所述内管1为正方形，外管2为圆管，内管1中心和外管2圆心重合，所述外管2包裹聚氨酯管壳3，聚氨酯管壳3外包裹镀锌钢板4。内管1由15CrMo钢板制作，外管2为螺旋缝钢管，裹聚氨酯管壳3的厚度为100-150mm，镀锌钢板4的厚度为0.2-0.3mm。运行时，干馏气从内管1流过，换热介质水从内管1和外管2中间流过，逆流运行。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，尽管参照前述实施例对本发明进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
