이러한 선출원 등록발명은 폐수는 폐수열 회수기의 위쪽으로 공급되어 폐수통로를 통하여 지그재그로 낙하 순환하고, 청수는 폐수열 회수기 하단에서 유입되어 청수유도관을 통하여 지그재그로 상승 순환하면서 폐수와 열교환하여 온도가 높아지도록 작동되었다.The invention of the prior application registration waste water is supplied to the top of the waste water heat recoverer and circulated in the zigzag through the waste water passage, and the fresh water flows from the bottom of the waste water heat recoverer to zigzag through the fresh water induction pipe to exchange heat with the waste water to increase the temperature. It worked.
그러나, 이와 같은 선출원 등록발명은 본체 내에 간격을 두고 다단으로 청수유도관을 설치하여, 그 청수유도관들 사이에 폐수통로가 확보되도록 한 구성을 가지기 때문에 다음의 몇가지 문제점들을 수반하게 되었다. 첫째 설정된 크기의 내용적을 가지는 본체 내에서 폐수와 열교환하는 청수를 온수로 변환시켜 주게 되므로, 열교환 용량이 한정되어서 소요 물량의 온수를 얻어내기 어려운 문제점이 있었으며, 둘째 본체 내의 청수유도관들 사이에 확보된 폐수통로를 통하여 폐수를 직접 통수시키게 되어서, 폐수가 통과하는 경로상에 이물질이 쌓여서 열교환 기능이 저하되는 문제점이 있었으며, 셋째 전체적인 구조가 복잡하고 불필요한 구성부품수가 증가하여서 설치비용이 과도하게 소요되는 문제점 등이 있었다.However, such a prior application registration invention is accompanied by the following problems because it has a configuration in which the fresh water guide pipes are installed in multiple stages at intervals in the main body, so that the waste water passage is secured between the fresh water guide pipes.

It is connected to the inlet 22 of the outlet side water supply unit 20.
이상에서 살펴 본 바와 같이, 본 발명의 폐열회수용 열교환장치는 유입측 및 유출측 통수유닛을 열교환관들로 연결하여 외부에서 공급되는 저온수를 통수시키는 단순구조로서, 폐온수와 접촉하도록 설치되는 열교환관들을 따라 통수되는 저온수가 폐온수와 열교환되도록 하여서 온도를 상승시켜 주도록 구성함으로써, 소요 물량의 온수를 내용적에 제한 받지 않고 얻어낼 수 있게 하여 주며, 폐온수에 포함된 이물질이 통수경로 상에 쌓여서 열교환 기능이 저하되는 현상이 발생됨을 방지하여 줄뿐만 아니라, 설치비용을 감축시켜 주는 등의 유용한 장점을 가지게 되는 것이다.As described above, the waste heat recovery heat exchange apparatus of the present invention is a simple structure for passing the low temperature water supplied from the outside by connecting the inflow side and the outflow side water supply units with heat exchange tubes, which is installed to be in contact with the waste hot water. It is configured to raise the temperature by allowing the cold water passed through the heat exchange tubes to exchange heat with the waste hot water so that the required amount of hot water can be obtained without limiting the contents, and foreign substances contained in the waste hot water Not only prevents the phenomenon that the heat exchange function is reduced by stacking, but also has a useful advantage such as reducing the installation cost.
