본 발명은 가열된 폐수와 차거운 청수가 서로 열교환되도록 하는 폐수열 회수기에 관한 것이다.The present invention relates to a wastewater heat recovery system for allowing the heated wastewater and cold fresh water to exchange heat with each other.

사각관체를 여러개 횡으로 용접하여서 된 열교환판을 일정간격 상하로 적층하여 가열된 폐수가 열교환판 사이를 위에서 아래로 지그재그로 흐르게 하고 열교환판의 사각관체 속으로는 차거운 청수가 아래서 위로 지그재그로 흐르게 하면서 서로 열교환되도록 하는 폐수열 교환기는 이건 출원인의 실용신안등록 제256619호 등에 의하여 알려져 있다.Heat-exchanging plates made by welding multiple rectangular pipes laterally are stacked up and down at regular intervals so that the heated waste water flows zigzag from top to bottom between heat exchange plates, and cool fresh water flows zigzag from bottom to top. The wastewater heat exchanger to heat exchange with each other is known from the Utility Model Registration No. 256619 by the applicant.

상기와 같은 종래의 폐수열 회수기는 폐수와 청수의 접촉면적을 동일체적 내에서 최대한 넓게 하여 폐수열 회수율이 매우 높은 등의 장점이 있는 것이나 사용에 의하여 점차 폐수열 회수율이 낮아지고 생산성도 떨어지며 내부청소가 쉽지 않고 내구성에 있어서도 만족하지 못하는 등의 문제가 있는 것이었다.The conventional wastewater heat recovery device has advantages such as the waste water heat recovery rate is very high by increasing the contact area between the waste water and the fresh water within the same volume, but the waste water heat recovery rate is gradually lowered and the productivity is lowered, and internal cleaning is not easy. There existed a problem, such as being unsatisfactory also in durability.

일반적으로 폐수 속에는 많은 기포가 있고 폐수가 열교환판 사이를 흐르면서 폐수속의 기포가 위로 떠올라 모이게 되나 이를 적절히 배출해주는 구성이 없어 폐 수속으로부터 떠오른 기포들이 점차 열교환판의 저면에 쌓이면서 열교환판 저면과 폐수사이에 공기층을 형성하게 되고 이와 같이 열교환판 저면과 그 아래를 흐르는 폐수 사이에 기포에 의한 공기층이 형성되면 열교환판 속으로 흐르는 청수와 열교환판 저면아래로 흐르는 폐수의 열교환을 공기층이 방해하여 열교환효율이 많이(최대 40%까지) 떨어지게 되는 것이다.In general, there are many bubbles in the wastewater, and the wastewater flows up between the heat exchanger plates, and bubbles in the wastewater float up and collect, but there is no configuration to properly discharge them. If an air layer formed by air bubbles is formed between the bottom of the heat exchange plate and the wastewater flowing below the air layer, the air layer interferes with the heat exchange between the fresh water flowing into the heat exchange plate and the bottom of the heat exchange plate. (Up to 40%).

그러나 공기배출은 신중하게 하지 아니하면 폐수열의 손실을 초래하게 된다.However, air emissions can lead to the loss of waste heat if not carefully taken into account.

또한 열교환판은 금속파이프를 횡으로 용접하여서된 구성이고 내부에는 고압의 청수가 흐르고 있어 사용에 의하여 중앙부가 점차 아래로 쳐져 휘어지게 되고 열교환판의 중앙부가 아래로 쳐져 휘어지면 열교환판 사이를 흐르는 폐수의 흐름을 방해하여 생산성이 떨어지게 될 뿐 아니라 열교환판의 쳐짐현상은 열교환판을 구성하는 사각파이프의 용접부위(부분용접한다)가 파손되게 하여 폐수열 교환기의 사용수명을 단축하게 되는 원인이 된다.In addition, the heat exchanger plate is constructed by welding metal pipes horizontally, and high-pressure fresh water flows inside, and the center part of the heat exchanger plate is bent downward due to its use. Not only does the productivity of the heat exchanger plate fall down due to disturbance of the flow of the heat exchanger, but also the welding part (welding part) of the square pipe constituting the heat exchanger plate is damaged, thereby shortening the service life of the wastewater heat exchanger.

일반적으로 폐수에는 많은 찌꺼기들이 섞여 있으므로 폐수가 흐르는 폐수열 회수기는 수시로 내부청소를 해주어야 하며 내부청소방법으로서는 폐수열 회수기의 가동을 중지하고 청수를 폐수유입구에 투입하여 폐수가 흐르는 공간에 청수가 흐르게하는 방법으로 청소를 하게 되나 이러한 방법으로 하는 청소는 내부에 쌓인 찌꺼기들을 완전히 배출할 수가 없어 폐수열 회수기 내에 늘 다소의 찌꺼기들이 쌓여 있게되어 폐수의 원활한 흐름을 방해하므로서 생산성이 저하되고 점차 찌꺼기들이 많이 쌓이게 되면 부득이 폐수열 회수기를 분해청소하여야 한다.In general, the wastewater contains a lot of waste, so the wastewater heat recovery system in which the waste water flows should be internally cleaned from time to time.The internal cleaning method is to stop the operation of the wastewater heat recovery system and put the fresh water into the wastewater inlet so that the fresh water flows into the wastewater flowing space. Although cleaning is performed in this way, the wastes accumulated inside can not be completely discharged, and some wastes are accumulated in the waste water heat recovery machine, which hinders the smooth flow of waste water. Disassembler should be disassembled and cleaned.

그러나 폐수열 회수기는 내부압때문에 대부분의 내외부 구성들이 용접, 리벳 등의 방법으로 견고하게 결합되어 있어 쉽게 분해할 수 있는 구성이 아니므로 분해청소가 매우 어렵고 내부에 찌꺼기가 어느 정도 쌓여있는지도 분해를 하기 전에는 알 수가 없는 문제가 있는 것이었다.However, due to internal pressure, the wastewater heat recovery system is not easily disassembled because most internal and external components are firmly combined by welding or riveting methods, so it is very difficult to clean and decompose the amount of debris inside. There was an unknown problem.

폐수열 회수기 내부에는 청수와 폐수에 의하여 상당한 고압(7~10kg/cm2)이 형성되기 때문에 이러한 고압에 대한 내압효과와 외관상의 미감을 위하여 종래의 폐수열 회수기의 지붕은 철판으로 제작하되 평면형상이 아니고 둥근 원호형상으로 되어 있다. Since the high pressure (7 ~ 10kg / cm2) is formed by the fresh water and the waste water inside the waste water heat recoverer, the roof of the conventional waste water heat recoverer is made of iron plate for the effect of pressure resistance and appearance on the high pressure. It is arc-shaped.

그러나 지붕이 둥근형상이라 해도 내부의 고압 때문에 용접부위가 파손되거나 철판자체가 융기되면서 찢어지는 경우가 있어 폐수열 회수기의 사용수명을 단축하는 원인이 되고 있다.However, even if the roof has a round shape, the welding part may be broken due to the high pressure inside or the steel plate itself may be torn and torn, thereby shortening the service life of the wastewater heat recovery device.

본 발명은 이러한 제반문제를 해결하기 위한 것으로서 열교환판을 구성하는 여러개의 사각파이프 중 폐수 낙하공 형성을 위하여 짧게 구성한 사각파이프 저면에 공기배출공과 같은 공기배출수단을 형성하여 폐수 내의 기포가 지그재그로 상승하여 외부로 배출되게 하므로서 폐수열의 손실을 최소화하면서 열교환판과 폐수사이에 공기층이 형성되지 않도록하여 열교환율이 현저히 높아지도록 하였다.The present invention has been made to solve the above problems, by forming an air discharge means such as an air discharge hole on the bottom of the rectangular pipe shortly configured to form a waste water drop hole among the plurality of square pipes constituting the heat exchange plate, bubbles in the waste water rises zigzag The heat exchange rate was significantly increased by preventing the formation of an air layer between the heat exchanger plate and the waste water while minimizing the loss of waste water heat.

열교환판의 저면에 횡으로 보강프레임을 용접하여 열교환판의 쳐짐현상을 방지하므로서 사용에 의하여 점차생산성이 저하되는 것을 방지하고 내구성도 높도록 하였다. 이때 보강프레임이 열교환판 저면 아래로 다소 돌출하게 되나 보강프레임의 돌출정도가 작고 또 폐수의 흐름을 방해하는 찌꺼기들은 대부분 위로 뜨지 않고 가라앉아 흐르기 때문에 보강프레임의 돌출에 따른 생산성 저하 정도는 매우 적다. 그러나 보강프레임의 돌출문제는 열교환판 간의 간격을 약간씩 더 높게 형성해주므로서 해결할 수 있다.The reinforcing frame was welded to the bottom of the heat exchanger plate transversely to prevent sagging of the heat exchanger plate, thereby preventing the productivity from being gradually lowered by use and increasing durability. At this time, the reinforcing frame slightly protrudes below the bottom of the heat exchanger plate, but the degree of protrusion of the reinforcing frame is small, and the wastes that hinder the flow of waste water sink and do not float upward. However, the problem of protrusion of the reinforcement frame can be solved by forming a slightly higher gap between the heat exchange plates.

폐수열 회수기의 본체 일측에 개폐판을 형성하고 개폐판을 쉽게 분리할 수 있도록 볼트 등으로 체결하므로서 개폐판을 분리하여 자주 내부상태를 점검할 수 있도록 하고 청수로 내부청소를 할 때는 청수 청소 후 개폐판을 분리하고 개폐판에 의하여형성된 개구부로 청소도구를 넣어 청수에 의하여 제거되지 않고 잔류하는 찌꺼기들을 완전히 청소할 수 있도록 하였다.Opening / closing plate is formed on one side of the main body of waste water heat recovery system and fastened with bolts for easy separation of the open / close board, so that the open / close board can be checked frequently to check the internal condition. Was removed and a cleaning tool was put into the opening formed by the opening and closing plate to completely clean the remaining debris without being removed by the fresh water.

폐수열 회수기의 지붕을 둥글게 하지않고 평면형상으로 하여 철제보강재의 시공이 용이하도록 하였고 시공이 용이한 평면지붕 위에 여러개의 철제보강재를 종횡으로 용접하여 지붕을 보강하고 측벽의 외면에도 일정간격으로 철제보강재를 수직으로만 용접보강하므로서 본체가 내부의 고압에도 오래 견딜 수 있도록 하였고, 철제보강재가 폐수열 회수기의 외면에 돌출하므로서 본체가 보강될 뿐 아니라 보온재시공이 용이하므로 폐수열 회수기의 지붕과 측벽에 보온재를 접착시공하므로서 폐수열이 외부로 손실되는 것을 최소화한 것이다.It is easy to install steel reinforcement by making flat shape without rounding the roof of waste water heat recovery machine.We welded several steel reinforcements vertically and horizontally on the flat roof which is easy to construct, reinforcing the roof and applying steel reinforcement at regular intervals to the outer surface of the side wall. Welded reinforcement only vertically so that the body can withstand high pressure for a long time. As steel reinforcement protrudes on the outer surface of waste water heat recovery machine, not only the body is reinforced but also easy to install insulation material. This minimizes the loss of wastewater heat to the outside.

본 발명의 실시예를 첨부 도면에 따라 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도1에서와 같이 폐수열 회수기(1)내에 사각파이프(2a)를 여러개 횡으로 용접하여서된 열교환판(2)을 상하 일정간격으로 적층하고 한 개의 열교환판(2)에는 중앙과 좌우에 다른 사각파이프(2a)보다 짧은 단관(2b)을 용접하므로서 단관(2b)의 일측 단부와 격판(3) 사이에 폐수낙하공(5)이 형성되게 하였다.As shown in FIG. 1, the heat exchanger plates 2 obtained by welding several square pipes 2a laterally in the wastewater heat recovery unit 1 are laminated at regular intervals up and down. By welding the short pipe 2b shorter than (2a), the wastewater dropping hole 5 was formed between one end of the short pipe 2b and the diaphragm 3.

도 2에서와 같이 열교환판(2)의 양측 입구는 좌우격판(3)(3')과 연결부재(4)(4')에 의하여 서로 연결된다.As shown in FIG. 2, both side inlets of the heat exchange plate 2 are connected to each other by the left and right partition plates 3, 3 ′ and the connecting members 4, 4 ′.

좌우격판(3)(3')에는 도 3과 도 4에서와 같이 여러개의 관통공(3a)(3a')이 형성되어 있고 관통공(3a)(3a')에는 도 2 및 도 5에서와 같이 각각 열교환판(2)의 사각파이프(2a)의 입구가 삽입된다.In the left and right plates 3 and 3 ', a plurality of through holes 3a and 3a' are formed, as shown in FIGS. 3 and 4, and the through holes 3a and 3a 'are shown in FIGS. Likewise, the inlets of the square pipes 2a of the heat exchange plates 2 are respectively inserted.

도 1에서와 같이 열교환판(2)을 구성하는 사각파이프(2a) 중 길이가 짧은 단관(2b)은 한 쪽이 다른 사각파이프(2a)보다 짧도록 구성되어 있고 이러한 구성은 각 층의 열교환판(2)마다 반대로 구성되어 있어 단관(2b)의 짧은 쪽과 격판(3)(3') 사이에 형성되는 폐수 낙하공(5)이 각층마다 서로 반대쪽에 형성되므로 폐수가 열교환판(2)사이를 위에서 아래로 지그재그로 흐르게 된다.As shown in FIG. 1, the short end pipe 2b of the square pipes 2a constituting the heat exchange plate 2 is configured so that one side is shorter than the other square pipe 2a, and this configuration is a heat exchange plate of each layer. The waste water dropping holes 5 formed between the short sides of the short pipes 2b and the diaphragms 3 and 3 'are formed on opposite sides of each layer so that the waste water is formed between the heat exchange plates 2, respectively. Zigzag from top to bottom.

도 3 및 도 4에서와 같이 열교환판(2)의 단관(2b)의 양측단부 중 폐수낙하공(5)이 형성되는 쪽의 단부(2b-1)는 격판(3)(3')과 사이에 폐수낙하공(5)의 크기만큼 간격을 두고 위치한다. 그 반대쪽 단부(2b-2)는 다른 사각파이프(2a)의 단부보다 격판(3)(3')의 두께만큼 짧게 형성하므로서 다른 사각파이프(2a)의 단부가 격판(3)(3')의 관통공(3a)(3a')을 관통하면 단관(2b)의 단부(2b-2)는 격판(3)(3')의 내면, 관통공(3a)(3a')이 없는 부분에 접하게 된다.As shown in FIGS. 3 and 4, an end portion 2b-1 of the side of the end pipe 2b of the heat exchange plate 2, on which the wastewater dropping hole 5 is formed, is separated from the diaphragm 3, 3 ′. Located at intervals of the size of the waste water dropping hole (5). The opposite end 2b-2 is formed to be shorter than the end of the other square pipe 2a by the thickness of the diaphragms 3 and 3 'so that the end of the other square pipe 2a is When penetrating through the through holes 3a and 3a ', the end portion 2b-2 of the short pipe 2b comes into contact with the inner surface of the diaphragm 3 and 3' and the portion without the through holes 3a and 3a '. .

사각파이프(2a)의 단부는 관통공(3a)(3a')을 관통하여 격판(3)(3')과 용접되므로 사각파이프(2a)에는 청수만 유입된다.Since the end of the square pipe 2a penetrates the through holes 3a and 3a 'and is welded with the diaphragms 3 and 3', only fresh water flows into the square pipe 2a.

단관(2b)의 단부(2b-2)는 관통공(3a)(3a') 사이의 격판(3)(3') 내면에 용접되므로 폐수가 흘러나오거나 청수가 흘러들어가지 않는다.The end portion 2b-2 of the short pipe 2b is welded to the inner surface of the diaphragm 3 and 3 'between the through holes 3a and 3a', so that the waste water does not flow out or the fresh water does not flow.

도 2 및 도 5에서와 같이 격판(3)(3')에는 청수의 흐름을 안내하는 연결부재(4)(4')가 용접된다. 연결부재(4)(4')는 도 3 및 도 4에서와 같이 단면이 원호형상이고, 도 2와 도 5에서와 같이 한개가 상하로 2개층의 열교환판(2) 입구를 서로 연결되게하는 구성이다.As shown in Figs. 2 and 5, the diaphragms 3 and 3 'are welded with connecting members 4 and 4' for guiding the flow of fresh water. As shown in FIGS. 3 and 4, the connecting members 4 and 4 ′ are arcuate in cross section, and as shown in FIGS. 2 and 5, one of the connecting members 4 and 4 ′ connects the inlets of the two heat exchange plates 2 to each other. Configuration.

다만, 청수유입구(6)와 청수배출구(7)가 형성된 맨아래와 맨위의 연결부재(4)(4')는 각 한개씩의 열교환판(2)과 연결된다.However, the bottom and top connecting members 4 and 4 'on which the fresh water inlet 6 and the fresh water outlet 7 are formed are connected to one heat exchange plate 2, respectively.

폐수는 단관(2b)에 의하여 형성되는 폐수 낙하공(5)이 각층마다 서로 반대방향에 형성되어있어 폐수가 유입구(8)로 흘러들어 온 다음에는 반대방향에 형성된 각층의 폐수 낙하공(5)을 따라 흐르게 되므로 그 흐름은 도 2에서 폐수흐름방향을 도시한 화살표(A)와 같이 지그재그로 흘러내린 후 폐수배출구(9)로 배출된다.The wastewater is formed in the opposite direction to each layer by the wastewater dropping holes 5 formed by the single pipe 2b, and after the wastewater flows into the inlet 8, the wastewater dropping holes 5 in each layer formed in the opposite direction. Since the flow flows along the zigzag as shown by the arrow (A) showing the wastewater flow direction in Figure 2 is discharged to the wastewater outlet (9).

청수는 펌프(도시안됨)의 펌핑압에 의하여 맨 아래의 청수유입구(6)로 들어가 위로 흐르며 도 2에서와 같이 서로 반대방향에서 엇갈리게 2개층씩 열교환판(2) 을 연결하는 연결부재(4)(4')의 안내에 따라 청수흐름방향을 도시한 화살표(B)와 같이 열교환판(2) 내부를 상향 지그재그로 흐른 다음 청수배출구(7)로 배출된다.The fresh water enters the fresh water inlet 6 at the bottom by the pumping pressure of the pump (not shown) and flows upwards, and as shown in FIG. According to the guidance of 4 ', the inside of the heat exchange plate 2 is zigzag upward as shown by the arrow B showing the fresh water flow direction, and then discharged to the fresh water outlet 7.

열교환판(2)의 구성은 폐수열 회수기 내에서 폐수와 청수가 서로 다른 방향으로 지그재그로 흐르게 하면 되므로 반드시 본 발명에서 예시한 것으로 한정하지 아니한다.The configuration of the heat exchange plate 2 is not necessarily limited to those exemplified in the present invention because the waste water and the fresh water may be zigzag in different directions in the waste water heat recovery system.

공기배출공(10)은 도 1 및 도 6에서와 같이 각층마다 열교환판(2)의 단관(2b) 중 어느 것 하나의 저면에 여러개 뚫어 열교환판(2)의 저면에 기포에 의한 공기층이 형성되지 않도록 한다.As shown in FIGS. 1 and 6, the air discharge holes 10 are drilled in the bottom surface of any one of the short pipes 2b of the heat exchange plate 2 in each layer to form an air layer formed by air bubbles in the bottom surface of the heat exchange plate 2. Do not
