본 고안은 호텔이나 대중목욕탕 또는 대형 건물등 대량의 온수를 사용하는 급탕 장치의 폐수열을 회수하는 재열장치(heat recycling system)에 관한 것이다.The present invention relates to a heat recycling system for recovering wastewater heat of a hot water supply device using a large amount of hot water, such as a hotel, a public bath or a large building.

종래 이와 같이 폐수열을 회수하는 재열장치는 제 1 도에 보인바와 같이 원통형의 본체(1)의 상하에 냉수입구(3)와 온수출구(4)를 설치하여 가열수자켓(2)를 형성하고 그 양단에 설치된 원판형의 브라켓(5)에 동관등으로 형성된 복수의 전열관(6)을 확관 또는 용접 등의 방법으로 고정하고 그 외부의 경판(7) 사이에 폐수 자켓(8)을 형성하여, 폐수입구(9)로 유입된 폐수가 폐수자켓(8)에서 각 전열관(6)으로 분배되어 가열수자켓(2)내의 냉수를 온수로 가열하도록 열교환한 뒤 폐수출구(10)으로 유출되도록 구성 및 작동하여, 가열된 오수를 직접 사용하거나, 주 보일러에 공급하여 연료를 절감하고 열 효율을 증대시키는 효과가 있었다.Conventionally, the reheating device for recovering wastewater heat is provided with a cold water inlet 3 and a hot water outlet 4 above and below the cylindrical body 1 to form a heated water jacket 2 as shown in FIG. A plurality of heat transfer tubes 6 formed of copper tubes or the like are fixed to the disk-shaped brackets 5 provided at both ends by expansion or welding, and a wastewater jacket 8 is formed between the external hard plates 7 so that wastewater is discharged. The wastewater flowing into the inlet (9) is distributed from each wastewater jacket (8) to each heat pipe (6), and is configured and operated so that the cold water in the heated water jacket (2) is heated to heat the hot water and then flows out to the waste outlet (10). By using the heated sewage directly, or by supplying to the main boiler has the effect of saving fuel and increasing the thermal efficiency.

그러나 이와 같은 종래의 재열장치는 전열 경로의 길이가 짧아 열 효율을 증대 시키기 위해 소직경의 전열관을 다수 배치하여야 하므로, 전열관의 직경이 작아 폐수에 혼합된 오물이나 스케일(scale) 등에 의해 전열관이 쉽게 폐색될뿐 아니라, 내부 청소도 매우 어려우며, 특히 직경이 작으므로 관벽의 두께도 얇아 부식에 의해 쉽게 손상되어 폐수가 혼입될 우려가 있어서 수명이 매우 짧은 결점이 있었다.However, the conventional reheater has a short length of the heat transfer path, and thus, a large number of small diameter heat transfer tubes must be disposed in order to increase thermal efficiency. Therefore, the diameter of the heat transfer tube is small so that the heat transfer tube is easily separated by dirt or scale mixed in the waste water. In addition to occlusion, the internal cleaning is also very difficult. In particular, since the diameter is small, the pipe wall is also thin, which is easily damaged by corrosion, and waste water may enter, resulting in a very short lifespan.

본 고안은 상술한 종래의 문제점을 해결하고자 안출된 것인바, 이하 첨부도면에 의거 상세히 설명한다.The present invention is devised to solve the above-described problems, will be described in detail based on the accompanying drawings.

본 고안 재열장치는 상술한 종래의 재열장치에 있어서, 본체(1)의 내부에 가열수 자켓(2)을 단면 방향으로 3등분하도록 각각 120°의 각도로 전개된 3개의 안내판(13; 13a,13b,13c)으로 구성된 가열수 유도장치(11)를 구비하며, 안내판(13)에는 3개로 구분된 가열수 자켓(2)이 연통될 수 있도록 그 단부에 절개부(12; 12a,12b) 또는 연통구멍이 형성된다.The reheating device of the present invention comprises three guide plates 13; 13b, 13c having a heated water induction device 11, and the guide plate 13 has a cutout portion (12; 12a, 12b) at its end so that three separate heated water jackets (2) can communicate; Communication holes are formed.

이와 같은 구성의 본 고안 재열장치의 작동을 제 3 도를 참조로 하여 설명하면 (도면에서 전열관은 도시의 편의상 생략하였음) 냉수입구(3)로 유입된 가열수는 안내판(13a,13c)에 따라 가열수 자켓(2)의 제 1공간(2a)을 이동한 뒤 절개부(12a)를 통해 제 2공간(2b)으로 유입되고 다시 절개부(12b)를 통해 제 3공간(2c)을 흐른 뒤 온수출구(4)로 배출되고, 이에 따라 가열수 자켓(2)내에 수납되어 고온의 폐수가 유통되는 전열관(6)과 충분한 전열 길이를 유지하게 된다.Referring to the operation of the present invention reheating device having such a configuration with reference to Figure 3 (in the drawing, the heat transfer tube is omitted for convenience of illustration) the heating water introduced into the cold water inlet (3) according to the guide plates (13a, 13c) After moving the first space (2a) of the heated water jacket (2) flows into the second space (2b) through the cutout (12a) and flows through the third space (2c) through the cutout (12b) again The hot water outlet 4 is discharged to the hot water outlet 4, thereby keeping the heat transfer pipe 6 and a sufficient heat transfer length, which are accommodated in the heated water jacket 2 and in which the hot waste water flows.

이와 같은 본 고안 재열장치는 제 4 도에 보는 바와 같이 복수로 병렬 배치하여 직렬 연결할 수 있으며 이에 따라 전열 길이는 더욱 길어지게 된다 (미설명 부호 14는 폐수 연결관, 15는 가열수 연결관, 16과 17은 각각 지지브라켓과 지지대이고, 18은 내부 청소를 용이하게 하기 위한 개폐구이다.).Such a reheater of the present invention can be connected in series by placing a plurality in parallel as shown in Figure 4, and thus the heat transfer length becomes longer (not shown 14 is a wastewater connector, 15 is a hot water connector, 16 And 17 are support brackets and supports, respectively, and 18 are openings for easy internal cleaning.).

이상과 같이 본 고안 재열장치는 가열수가 자켓내를 복수회 통과(소위 3패스(pass)방식)하게 되어 전열 길이가 길어지고 이에 따라 전열 효율이 증대되므로 종래와 같은 소직경의 전열관을 사용하지 않고도 충분한 전열 효과를 얻을 수 있어서, 충분히 대직경의 관을 사용할 수 있게 됨에 따라 오물 등에 의한 전열관의 폐색이 방지되고 내부 청소가 용이하며 관벽 두께가 증대되어 부식에 대한 저항이 증대되어 수명이 현저히 연장되는 이점이 있다.As described above, the reheating device of the present invention has a heating water passing through the jacket a plurality of times (so-called three-pass method), so that the length of heat transfer is increased and thus the heat transfer efficiency is increased, without using a heat pipe having a small diameter as in the prior art. It is possible to obtain a sufficient heat transfer effect, so that the tube with a sufficiently large diameter can be used to prevent the blockage of the heat transfer tube due to dirt, etc., to easily clean the inside, and to increase the wall thickness of the tube, thereby increasing the resistance to corrosion, thereby significantly extending the life. There is an advantage.

뿐만 아니라, 제 4 도와 같이 복수 병렬 연결하는 경우에는 종래의 동일 용량의 재열장치에 비해 설치 면적이 현저히 감소되며 모듈(module)화가 가능하여 소용 용량에 따라 적절한 용량의 재열장치를 구성할 수 있는 등 여러가지 이점이 있다.In addition, when the plurality of parallel connection as shown in the fourth diagram, the installation area is significantly reduced compared to the conventional reheating device of the same capacity, it is possible to modularize the reheating device of the appropriate capacity according to the required capacity, etc. There are several advantages.

이상의 설명은 본 고안을 예시하기 위한 것으로 본 고안은 이에 국한되는 것은 아니며, 예를 들어 가열수 유도장치의 안내판을 2개 또는 4개 이상으로 형성하는 구성 역시 당연히 본 고안의 범위내에 포함된다.The above description is intended to illustrate the present invention, but the present invention is not limited thereto. For example, a configuration of forming two or four or more guide plates of the hot water induction apparatus is naturally included within the scope of the present invention.
