본 고안은 온수상태로 배수되는 물의 잔열을 회수하여 이용하는 열회수기에 관한 것으로, 특히 목욕탕등에서 배수되는 온수를 코일형으로 말아 집적시켜서된 열교환수단에 공급하여 열교환시켜줌으로써 폐열을 회수할 수 있도록된 폐열 회수기에 관한 것이다.The present invention relates to a heat recoverer for recovering the residual heat of the water drained in the hot water state, in particular, the waste heat recoverer to recover the waste heat by supplying heat exchange to the heat exchange means by rolling the coiled hot water in the bath form It is about.

일반적으로 대중 목욕탕등에서 사용하고 버려지는 물, 즉 폐수는 그 온도가 사람체온보다는 다소 높은 40℃정도로 방류되는바, 이러한 폐수의 열을 재활용하고자하는 폐열회수장치는 이미 여러종류가 고안되어져 있다. 그런데 이렇게 고안되어진 대부분의 폐열회수 장치는 큰 저장물 탱크와 같으 원통내에 새로이 공급되는 냉수가 통과되는 도관을 장착하여 놓고 있는 것이기 때문에, 상기의 저장탱크내에 목욕탕등에서 방류되는 고온의 폐수를 통과시킴에 따라 냉수가 통과되는 도관에 전도되어 가열한 다음 이와함께 도관내의 냉수가 데워지도록한 방식을 활용하고 있는 것이다.Generally, the waste water used in public baths, etc., that is, the wastewater is discharged to about 40 ° C., which is somewhat higher than the human body temperature. Thus, various kinds of waste heat recovery apparatuses for recycling the wastewater heat have been devised. However, since most of the waste heat recovery devices designed in this way are equipped with conduits through which cold water is newly supplied in the cylinder, such as large storage tanks, the high temperature wastewater discharged from the bathhouses and the like in the storage tank is passed through. Therefore, the cold water is conducted to the conduit through which the conduit is heated, and then the cold water in the conduit is utilized.

그러나 종래의 폐열회수 장치는 열교환용 원통탱크내에 냉수 공급도관이 플랜지(flange)등에 의해 고정설치되어 있는 관계로 또는 제작의 용이성 문제에 따라 단순히 탱크내에 도관을 내장시킨 형식에 지나지 않기 때문에 목욕탕등으로부터 폐수에 실려 탱크내로 혼입되는 때와 비누찌꺼기 또는 세제용 비닐용기등에 의해 탱크내가 막혀지게되면 내부를 청소할 수가 없게되고, 그에따라 목욕탕으로부터 방류되는 폐수가 역류되게 되는등 불편과 저효율의 결점이 있었다.However, in the conventional waste heat recovery apparatus, since the cold water supply conduit is fixedly installed in a cylindrical tank for heat exchange by a flange or the like, or simply because the conduit is built in the tank due to the ease of manufacture, the waste heat recovery device is used. If the tank is clogged with waste water and mixed with soap residue or vinyl containers for detergents, the inside of the tank cannot be cleaned, and the waste water discharged from the bath becomes countercurrent, resulting in inconvenience and low efficiency.

또한 냉수공급도관의 구성에 있어서도 하나의 냉수공급 라인을 폐수 저장탱크의 분지된 형태로 설치하게 되므로 탱크 출구에서의 물공급이 원활하지 못한점도 사용상 불편한 점으로 지적되었던 것이다.In addition, in the configuration of the cold water supply conduit, since one cold water supply line is installed in a branched form of the waste water storage tank, it was pointed out that the water supply at the outlet of the tank was not smooth.

이에 본 고안은 상기와 같은 불편과 저효율을 개선시켜 주기 위해 목욕탕등에서 배수되는 폐수가 통과하는 열교환탱크를 그 용량에 따라 1개로 사용하거나 또는 여러개의 격실로 구획짓기위해 분리판을 설치하고 상기 분리판에 의해 구획딘 각 격실내에는 열교환 면적을 극대화시키도록 코일형으로 만 금속파이프로된 열교환라인을 설치하여 상기 열교환라인 내부로 공급 냉수가 통과하도록 하는 한편, 열교환라인과 탱크 사이의 공간 및 열교환라인의 주위와 내부로 폐수가 통과되게하되 폐수와 냉수의 흐름 방향을 서로 반대로하고 폐수의 흐름은 폐수의 유입구와 유출구의 높이차를 이용한 수두차에 의한 자유 흐름이 되도록 하여 폐수와 냉수 사이에 충분하고도 효과적인 열교환이 이루어지도록한 폐열 회수기를 제공하기 위한 것이다.In order to improve the inconvenience and low efficiency as described above, the present invention uses a heat exchange tank through which wastewater drained from a bathhouse, etc., is divided into several compartments or partitions into multiple compartments, and installs the separator plate. In each compartment partitioned by, a heat exchange line made of metal pipes with only coils is installed to maximize the heat exchange area so that the supplying cold water passes through the heat exchange line, while the space between the heat exchange line and the tank and the heat exchange line The wastewater is allowed to pass through and inside, but the flow direction of the wastewater and cold water is reversed to each other, and the flow of the wastewater is sufficient between the wastewater and the cold water by the free flow by the head difference using the height difference between the inflow and outflow of the wastewater. It is also to provide a waste heat recovery device to achieve an effective heat exchange.

이하 첨부된 예시도면을 참조하여 본 고안을 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 폐열회수기(1)의 본체를 이루는 탱크(2)의 내부에 수개의 분리판(12)을 설치하여 몇개의 격실(3)을 형성시키고, 상기 각 격실(3)내에는 냉수가 공급되는 코일형의 금속파이프로된 열 교환라인(4)이 삽입되어 서로 연결되어 있는 한편, 상기 탱크(2)의 양쪽 상단에는 폐수의 유입구(5)와 유출구(6)가 각각 형성되어 있고 상기 탱크(2)윗면에는 분리 가능한 뚜껑(7)이 설치된 구조로 되어있다.The present invention forms several compartments 3 by installing several separation plates 12 inside the tank 2 constituting the main body of the waste heat recovery machine 1, and supplies cold water to each of the compartments 3. The heat exchange line 4 of the coil-shaped metal pipe is inserted into and connected to each other, while the inlet 5 and the outlet 6 of the waste water are formed at both upper ends of the tank 2, respectively. (2) On the upper side, a detachable lid 7 is provided.

도면중 미설명 부호8은 새로운 공급냉수 유입구, 9는 유출구, 10은 이물질 드레인 구멍, 11은 개구부이다.In the figure, reference numeral 8 denotes a new supply cold water inlet, 9 outlet, 10 foreign material drain hole, and 11 opening.

이를 도면 제1도에서 보면, 폐수유입구(5)는 폐수유출구(6)보다 높게 형성시키고 격실(3)을 구획짓는 분리판(12)은 폐수유입구(5)로부터 밀폐된 방의 하부와 상부에 격번순으로 개구부(11)가 형성되어서 탱크(2)내의 폐수는 이 개구부(11)를 통해서만 순환되며 공급냉수 유입구(8)가 폐수유출구(6)쪽에, 또한 공급냉수유출수(9)는 폐수유입구(5)측에 설치시켜 열교환라인(4)내의 물이 효과적으로 더워지게 된다. 또한 냉수유입구(8)로부터 유입된 냉수는 각 열교환라인(4)으로 분지되어 데워지고 다시 공급유출구(9)에서 모아져 보일러실로 보내어져 소정의 온도로 가열되게 된다. 따라서 폐수유입구(5)로 목욕탕등에서 버려진 고온의 폐수(대략40℃정도)가 유입되면 제2도에서의 첫번째 격실(3)로 보내지고 이 폐수는 열교환라인(4)내의 물을 데워주면서 두번째 격실로 이동되는데 이때 분리판(12)하단의 개구부(11)를 통해서 두번째 격실에 폐수가 점점 차오르게 되면 이 폐수는 두번째 분리판(12)의 상단 즉 개구부(11)까지 차오르면 다시 세번째 격실로 흘러넘쳐 상기와 같은 방식으로 모든 격실에 폐수가 채워지게 된다. 이렇게하여 각 격실에 채워진 폐수는 폐수유출구(6)가 유입구(5)보다 낮아져 탱크(2)의 전체적인 수두차에 의해 폐수유출구(6)를 통해 방류되게되는 한편, 냉수유입구(8)로부터 유입된 냉수는 각 격실의 열교환라이(4)을 통과하는 동안 폐수유입구(5)근처에서는 온수로 되어 공급냉수 유출구(9)를 통해 사용자에게, 혹은 더 데워주기 위해 예열된 상태로 가열보일러내로 보내지게 된다.In FIG. 1, the wastewater inlet 5 is formed higher than the wastewater outlet 6, and the separator 12 partitioning the compartment 3 is spaced at the lower and upper portions of the room sealed from the wastewater inlet 5. The opening 11 is formed in turn so that the waste water in the tank 2 is circulated only through the opening 11 so that the supply cold water inlet 8 is directed to the waste water outlet 6, and the supply cold water outlet 9 is a waste water inlet ( 5) the water inside the heat exchange line 4 is effectively heated. In addition, the cold water introduced from the cold water inlet 8 is branched and heated in each heat exchange line 4 and collected at the supply outlet 9 and sent to the boiler room to be heated to a predetermined temperature. Therefore, when the high temperature wastewater (approximately 40 ° C.) discarded from the bathhouses enters the wastewater inlet (5), it is sent to the first compartment (3) of FIG. In this case, when the wastewater is gradually filled in the second compartment through the opening 11 at the bottom of the separator plate 12, the wastewater flows up to the top of the second separator 12, that is, the opening 11, and flows back to the third compartment. In the same way as above, all compartments are filled with waste water. In this way, the wastewater filled in each compartment is discharged from the cold water inlet 8 while the wastewater outlet 6 is lower than the inlet 5 so as to be discharged through the waste water outlet 6 by the overall water head of the tank 2. The cold water becomes hot water near the wastewater inlet (5) while passing through the heat exchange lie (4) of each compartment and is sent to the user through the supply cold water outlet (9) or into the heating boiler in a preheated state for warming up. .

또, 이 장치의 사용중에 폐수내에 혼입된 각종 이물질이 가열교환라인(4)사이에 끼이게되면 열전달 효율이 저하하므로 탱크 상부의 뚜껑(7)을 통해 브러시등을 넣어 수직으로 문질러주면 쉽게 이물질을 떼어낼 수 있고, 탱크바닥에 쌓여진 이물질은 바닥의 드레인 구멍(10)을, 통해 수비게 청소해낼 수가 있도록 되어 있다.In addition, if various foreign matters mixed into the wastewater during use of the device are caught between the heat exchange lines 4, the heat transfer efficiency is lowered. The foreign matter accumulated on the bottom of the tank can be removed, and the foreign matters can be cleaned out through the drain hole 10 at the bottom.

상기와 같은 본 고안에 따른 폐열회수기를 이용하므로서 물을 미리 데워주게 되므로 연료절약이 됨은 물론 그에 따른 공해방지 효과도 얻을 수 있고 그 구조가 간단하여 실용성이 높은 효과적인 고안인 것이다.By using the waste heat recovery device according to the present invention as described above, the water is preheated, so that the fuel can be saved as well as the pollution prevention effect.
