Abstract

본 발명은 폐열회수장치에 사용되는 분리형 열교환기 및, 이를 이용한 폐열회수장치의 보수방법에 관한 것으로, 보다 상세히는 저온부와 고온부를 분리형으로 제작하여 저온부식 현상이 발생하는 경우 저온부만을 교체하여 재사용함으로서 열교환기의 수명을 향상시키고, 폐열회수장치의 열교환기 정비작업시 부분적인 보수작업이 가능하여 정비원가 절감에 크게 기여할 수 있는 분리형 열교환기 및, 이를 이용한 폐열회수장치의 보수방법에 관한 것이다.The present invention relates to a separate type heat exchanger used in a waste heat recovery device, and a method for repairing a waste heat recovery device using the same. More specifically, the low temperature part and the high temperature part are manufactured in a separate type so that only a low temperature part is used when the low temperature corrosion phenomenon occurs. The present invention relates to a split type heat exchanger capable of improving the lifespan of a heat exchanger and performing partial maintenance work during the heat exchanger maintenance work of the waste heat recovery device, and contributing to the reduction of maintenance cost, and a method of repairing the waste heat recovery device using the same.

본 발명은 저온부와 고온부가 서로 탈착가능하도록 연결되는 구조를 갖추기 때문에, 저온부식이 발생되면 저온부를 교체시켜 새로운 저온부를 기존의 고온부에 연결시키고, 고온부식이 발생되면 고온부를 교체시켜서 새로운 열교환기를 구성한다. 본 발명의 분리형 열교환기를 이용하여 폐열회수장치의 열교환기를 교체시키면 저온부 또는 고온부만을 선택적으로 교체시킬 수 있기 때문에 정비원가 절감에 크게 기여하는 효과를 얻는 것이다.Since the present invention has a structure in which the low temperature portion and the high temperature portion are detachably connected to each other, when low temperature corrosion occurs, the low temperature portion is replaced to connect the new low temperature portion to the existing high temperature portion, and when the high temperature corrosion occurs, the high temperature portion is replaced to construct a new heat exchanger. do. When the heat exchanger of the waste heat recovery apparatus is replaced using the separate heat exchanger of the present invention, it is possible to selectively replace only the low temperature part or the high temperature part, thereby greatly reducing the maintenance cost.
