Abstract

本实用新型是一种旋流式波纹管换热器，它包括 壳体、换热波纹管、加热介质进口、加热介质出口、被 加热介质进口、被加热液体出口，其特征是：换热波纹 管采用盘旋式排列，管间用盘旋隔板隔开。本实用新 型的优点是：换热管之间完全由旋板隔开，无短路可 能，提高了传热效果；换热管被无间隙地夹在旋板之 间，消除了振动与碰撞的可能，提高了可靠性；解决了 波纹管换热器的壳程湍流不充分，影响传热的问题。

Description

本实用新型提供一种新型换热器，特别是一种具有盘旋式布管、盘旋式旋流板的管壳式波纹管换热器。
通常的管壳式换热器主要是由壳体及壳体内的传热管组成，为了增加壳程流程采用折流板进行折流，换热管布置呈三角形等距分布。这种结构换热管要穿过水平放置的折流板，由于安装的需要，折流板孔径要大于换热管，间隙较大，不但容易出现流体从间隙中直接流出，减少了折流作用，更严重的是容易发生换热管与折流板之间的振动碰撞，造成碰伤和振动疲劳，使换热管破裂，发生事故。国内外曾投入大量人力物力也未有更好的解决办法。特别是对于采用专利号为93228519.8“超薄型波纹管换热元件”制造的管壳式波纹管换热器，由于管壁很薄，这种振动和碰撞更容易发生。对这种高效换热器来说，这一问题已经构成推广应用的障碍。另外，由于波纹管的形状具有波峰和波谷，当波谷与折流板吻合时，间隙更大，出现流体短路与振动、碰撞的程度更为严重。
本实用新型的任务是提供一种新型结构的波纹管换热器，达到工作时流体无短路可能，换热管也不受振动与碰撞的损害的目的，使效率更高、更安全可靠，从而解决了波纹管换热器的主要问题。
本实用新型的目的是这样实现的：它包括壳体、换热波纹管、加热介质进口、加热介质出口、被加热介质进口、被加热液体出口，其特征是：换热波纹管采用盘旋式排列，管间用盘旋隔板隔开。
换热波纹管和盘旋隔板呈单盘旋或双盘旋。
各盘旋板间距一致或不一致。
图1是本实用新型的总体示意图。
图2是本实用新型换热管和盘旋隔板双盘旋排列示意图。
图3是本实用新型换热管和盘旋隔板单盘旋排列示意图。
根据附图1－2，本实用新型如已有的换热器，也包括封头1、壳体4、波纹管换热元件2、水－水交换用加热水进口5、加热水出口6、被加热水进口7、被加热水出口8。如果汽水交换，则被加热水进口5、被加热水出口6、蒸汽进口8、汽冷凝水出口7。要点是它的波纹管换热元件2成双盘旋排列，每层管间采用盘旋板3分开，盘旋板的中心点固定在上下底板上，外端固定在壳体4上，管2与板3之间无间隙。
根据附图3，本例波纹管换热元件2及盘旋板3均以单盘旋布置。随着换热管径的变化，隔板间距也随之变化。
本实用新型的优点是：壳体介质在盘旋板与换热管的波谷间流动，这样，一方面换热管之间完全由旋板隔开，无短路可能，提高了传热效果；另一方面，换热管被无间隙地夹在旋板之间，消除了振动与碰撞的可能，提高了可靠性。同时，由于壳程介质流动的流道变化复杂，其湍流程度大大提高，这也解决了波纹管换热器的壳程湍流不充分，影响传热的问题。
