The present invention relates to a system for washing a heat exchanger of an effluent heat pump. More specifically, the present invention relates to a system for washing an effluent heat exchanger, wherein the system washes a heat exchanger for collecting heat of discharged effluent, a water transferring pipe, and a water returning pipe. According to the structure of the present invention, a 3-directional valve (100) used in converting a direction of a water pathway is installed on the water transferring pipe (21). Thus, when the inside of a first circulation water pathway (20) is washed, the water pathway moving from a heat effluent storage tank (10) to a heat exchange plate (30) is blocked, and at the same time is opened to discharge washing water reversely circulated from the heat exchange plate (30) to the outside. The water returning pipe (22) has a 3-directional valve (101) used in converting a direction of a water pathway. Thus, the water pathway moving from a heat exchange plate (30) to a heat effluent storage tank (10) is blocked, and the water pathway of a washing water pipe (53) connected to a warm water storage tank (40) is opened. Thus, washing water is moved to the heat exchange plate through the water returning pipe (22). An opening and closing valve (102) for blocking or opening a water pathway is formed on a second water transferring pipe (51) or a second water returning pipe (52) in a second circulation water pathway (50). Thus, when the inside of the first circulation water pathway (20) is washed, the water pathway of the second circulation water pathway (50) is blocked.

Description

폐수열 히트펌프의 열교환기 세척 시스템{PANEL FOR FLAT PLATE HEAT EXCHANGER}{PANEL FOR FLAT PLATE HEAT EXCHANGER}

본 발명은 폐수열 히트펌프의 열교환기 세척 시스템에 관한 것으로서, 보다 상세하게는 방류되는 폐수의 열을 회수하는 열교환기와 송수관과 환수관을 세척하기 위한 폐수열 열교환기의 세척 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat exchanger cleaning system for a waste heat heat pump, and more particularly, to a heat exchanger for recovering heat of discharged wastewater, and a cleaning system for a waste heat heat exchanger for cleaning a water pipe and a water pipe.

일반적으로 목욕탕 및 공장 등지에서 배출되는 폐온수의 열을 열교환하여 새로 유입되는 지하수를 예열시켜 온수를 공급함으로서 온수를 만들기 위한 에너지를 획기적으로 절감시키기 위한 히트펌프식 폐열회수장치이다.It is a heat pump type waste heat recovery device to drastically reduce the energy for making hot water by supplying hot water by preheating new incoming ground water by heat exchange of heat of waste hot water discharged from a bathroom and a factory.

일반적으로 목욕탕이나 공장 등지에서는 사용하고 남은 30-40℃ 정도의 폐온수를 그대로 유출시켜 막대한 열에너지를 소비하고 있을 뿐만 아니라, 고온의 폐온수가 그대로 유출되는 경우에는 물을 정화시키는 미생물의 증식이 불가능하여 폐수처리비용이 증가하는 요인이 된다.Generally, the waste water of about 30-40 ° C. that is used in a bathroom or a factory is leaked out as it is, which consumes enormous heat energy. In addition, when the hot water of high temperature flows out as it is, And the cost of wastewater treatment is increased.

이러한 처리비용의 증대로 인하여 폐온수로부터 열을 회수하기 위한 장치가 개발되었다. 종래의 폐온수로부터 열을 회수하기 위한 장치는 고온의 폐온수를 열전도하여 저온의 지하수를 예열시키는 구성으로 이루어 진다.Due to this increased processing cost, an apparatus has been developed for recovering heat from wastewater. The apparatus for recovering heat from conventional wastewater is configured to preheat low-temperature groundwater by conducting heat of the wastewater hot water at a high temperature.

히트펌프식 폐열회수장치는 대한민국 특허청 등록번호 10-0435064호에 상세하게 설명되어 있으니 참고 바란다.The heat pump type waste heat recovery device is described in detail in Korean Patent Registration No. 10-0435064.

그리고 종래기술로서 첨부한 도 1내지 도 3에 도시한 바와 같이, 판형 열교환기(1)는 두 유체간의 고온과 저온의 열교환에 사용하는 성능이 우수한 장비로 건설,산업,식품공장,수산분야 등에서 광범위한 열교환장치로 활용되고 있으며, 고온의 유체의 열이 저온의 유체로 열이동을 하는 열판을 내부에 고정시키고 외부 양측면은 전면고정판(11)과 후방고정판(12)을 이용하여 열교환기의 형태를 유지하고, 제품을 견고히 유지시키는 역할을 한다.1 to 3, the plate-type heat exchanger 1 is a device excellent in performance for use in heat exchange between high and low temperatures between two fluids, and is used in construction, industry, food factory, The heat exchanger is used as a wide range of heat exchangers, and a heat plate, in which the heat of the high temperature fluid is heat-transferred to the low temperature fluid, is fixed inside, and the external both sides are formed by using the front fixing plate 11 and the rear fixing plate 12, And maintain the product firmly.

상기 열교환기(1)의 구성요소에 대해 살펴보면;As to the components of the heat exchanger 1,

상기 열교환판(2)은 도 2,3에 도시된 바와같이 판상체를 취하며, 상,하면으로 각각 2개의 수로공(4,4'4"4"')이 형성되므로써 구성되는 것으로, 이 열교환판(2)의 전면과 이면 테두리에 수로공(4,4')으로 유입된 온수와 냉수를 차단하는 고무패킹(5)이 위치된다.2 and 3, the heat exchange plate 2 is formed by forming two water holes 4, 4 ', 4 "and 4"' on the upper and lower surfaces, respectively, The rubber packing 5 for blocking hot water and cold water introduced into the water holes 4 and 4 'is positioned at the front and rear edges of the heat exchange plate 2.

상기 열교환판(2)은 상기 고무패킹(2)을 맞닿는 형태로써 적층구성하여 복수의 열 교환실(A)을 형성한다.The heat exchange plates (2) are laminated by forming the rubber packing (2) in contact with each other to form a plurality of heat exchange rooms (A).

그리고 도시한 2,3에서 확인되는 원형고무패킹(6)은 수로공(4,4',4",4"')의 외부 둘레에 밀착되어 물의 흐름를 차단한다. 예를들어 원형고무패킹(6)에 의해 차단된 곳에서는 수로가 차단되고 원형고무패킹(6)이 없는 곳은 수로가 열린 상태이다.And the circular rubber packing 6 identified in FIGS. 2 and 3 is brought into close contact with the outer circumference of the water channel 4, 4 ', 4' ', 4' '' to block the flow of water. For example, in the case where it is blocked by the circular rubber packing 6, the channel is cut off and the channel is open when the circular rubber packing 6 is not provided.

상기 원형고무패킹(6)은 상기 고무패킹(2)과 일체로 성형된다.The circular rubber packing (6) is molded integrally with the rubber packing (2).

상기 열교환판(2)은, 예를들어 전면에는 온수가 흐르도록하고, 이면에는 냉수가 흐르도록 하여 열을 교환한다. In the heat exchange plate 2, for example, hot water flows through the front surface and cold water flows through the back surface, thereby exchanging heat.

상세하게는 이어지는 후술에서 확인 되겠지만, 종래의 열교환기(1)는 원형고무패킹(6)을 이용하여 수로공(4,4',4",4"')의 외주연을 차단하거나 개방하여 복수의 열교환판(2)의 전면과 이면에 온수와 냉수가 흐르도록 하고 있다. 그 구성을 더 살펴보면 다음과 같다.The conventional heat exchanger 1 can block or open the outer circumferences of the water holes 4, 4 ', 4 "and 4"' by using the circular rubber packing 6, Hot water and cold water flow through the front and back surfaces of the heat exchange plate 2 of the first embodiment. The configuration is as follows.

전면으로 온수가 흐르도록 하기 위해서 상측에 형성한 2개소의 수로공(4,4')중 1개소의 수로공(4) 외주연을 개방하고, 전면으로 냉수가 유입되지 않도록 상측에 형성한 다른 1개소의 수로공(4')의 외주연은 원형고무패킹(6)으로 차단한다.In order to allow the hot water to flow to the front, the outer periphery of the hole 4 is opened by one of the two water holes 4, 4 'formed on the upper side, and another The outer periphery of one of the water holes (4 ') is blocked by the circular rubber packing (6).

그리고, 하단은 상측으로 유입된 온수가 온수배출배관(7')으로 배출되도록 2개소의 수로공(4",4"')중 1개소의 수로공(4")의 외주연을 개방하고 다른 한곳의 수로공(4"')은 원형고무패킹(6)으로 차단한다.The lower end opens the outer periphery of the water hole 4 "of one of the two water holes 4" and 4 "'so that the hot water introduced to the upper side is discharged to the hot water discharge pipe 7' One channel 4 "'is blocked with a round rubber packing 6.

그리고, 이면은 전면부와 반대로 냉수가 흐르도록 원형고무패킹(6)이 상측 수로공(4,4')과 하측수로공(4",4"')의 외주연을 개방하거나 차단하여 상측수로공(4')으로 유입된 냉수가 하측수로공(4"')을 지나 하측에 있는 냉수배출배관(8")으로 배출된다. The circular rubber packing 6 opens or cuts the outer circumferences of the upper water holes 4 and 4 'and the lower water holes 4' and 4 '' 'so that the cold water flows on the reverse side of the front surface, The cold water introduced into the holes 4 'is discharged through the lower water channel 4' 'to the cold water discharge pipe 8' 'at the lower side.

이와 같이 복수의 열교환판(2)들은 전면에 온수가 흐르고 이면은 냉수가 흐르도록함으로서 수로공(4,4')으로 유입된 온수와 냉수가 동시에 전면부와 이면으로 흘러 동시에 하측수로공(4",4"')을 경유하여 온수배출배관(7")과 냉수배출배관(8")을 통해 배출된다. In this way, the hot water flows on the front surface of the plurality of heat exchange plates 2 and the cold water flows on the back surface, so that hot water and cold water flowing into the water holes 4 and 4 'flow to the front portion and the back surface simultaneously, Quot ;, 4 "'through the hot water discharge pipe 7' 'and the cold water discharge pipe 8' '.

상기 온수는 상측수로공(4)과 연결시킨 온수유입배관(7')으로부터 온수를 유입받고 냉수는 상측수로공(4")과 연결시킨 냉수유입배관(8')으로부터 냉수를 유입받는다.The hot water flows from the hot water inflow pipe 7 'connected to the upper water hole 4 and the cold water flows from the cold water inflow pipe 8' connected to the upper water hole 4 '.

이와 같은 시스템을 장기간 사용하게되면 열교환판(2)은 온수에 포함된 여러가지 이물질이 쌓여 결국 열교환이 원활하게 이루어지지 않는다. When such a system is used for a long period of time, the heat exchange plate (2) accumulates various foreign substances contained in the hot water, so that heat exchange is not smoothly performed.

이럴경우 도 3과 같이 복수의 열교환판(2)을 분리하여 그 내부를 세척하는 방법을 선택함으로서 그 분리작업에 많은 시간을 낭비하고 있는 실정이다.In this case, as shown in FIG. 3, a plurality of heat exchange plates 2 are separated and a method of cleaning the inside of the heat exchange plates 2 is selected.

여기서 참고로, 이를 감안하여 종래에는 상기 온수배출배관(7")을 분리한 다음 온수유입배관(7')으로 온수 내지는 정화된 냉수를 공급하면 열교환판(2)에 쌓인 이물질 상당부분이 외부로 배출되므로 이러한 방법을 이용하고 있다.In view of this, conventionally, when hot water or purified water is supplied to the hot water inflow pipe 7 'after separating the hot water discharge pipe 7' ', a substantial part of the foreign matter accumulated in the heat exchanger 2 is discharged to the outside This method is used because it is discharged.

상기한 종래의 문제를 감안하여 안출된 것으로서 본원은 제1순환수로에 쌓인 이물질을 온수를 흘려보내 제1순환수로 외부로 배출하되, The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide an apparatus and a method for discharging foreign matter accumulated in a first circulation channel,

그 배출은 수로 라인을 변경한 다음 변경된 수로를 통해 외부로 배출하고자 한다.The discharge is to change the waterway line and then discharge it to the outside through the modified waterway.

폐수온수를 우회시켜 유속이 느리게한 상태에서 탁도를 감지하여 감지 효율을 높이고, 또 메인 배관이 아닌 우회배관에 탁도감지센서를 설치함으로서 정비가 편리하고, 또 우회배관 내에 탁도감시창을 닦아줄수 있는 밀대를 설치함으로서 감시창을 청소할 수 있는 장점이 있다.It is possible to improve the detection efficiency by detecting the turbidity in the state where the flow rate of the wastewater is slowed by slowing the flow rate and to install the turbidity sensor on the bypass piping instead of the main piping so that the maintenance is convenient and the turbidity monitoring window can be wiped in the bypass piping There is an advantage that the monitoring window can be cleaned by installing the plunger.

좀 더 상세한 과제는 후술로 이어지는 구체적인 내용에서 언급된다.A more detailed task is mentioned in the following detailed description.

Also, by installing the turbidity sensor on the bypass pipe instead of the water pipe or the water pipe, There is an advantage that the monitoring window can be cleaned by installing a wipe that can be polished.

본원은 산업체(양식장, 수영장 목욕탕 등) 등의 수조(미도시)로부터 온수를 펌프하여 냉수와 열교환 한다. The company pumped hot water from a water tank (not shown) of industry (farm, swimming pool bath, etc.) and exchanges heat with cold water.

첨부한 도면에 의하면, 산업체로부터 발생되어 버려지는 온열이 존재한 폐수(온열폐수라 함)를 임시 보관하는 온열폐수저장탱크(10)가 있고 상기 온열폐수저장탱크(10)의 온열폐수를 송수하고 환수하는 송수관(21)과 환수관(22)이 있으며 상기 송수관(21)과 환수관(22)에 연결되어 온열폐수가 경유하는 열교환판(30)의 일면(31)을 포함한 제1순환수로(20)와,According to the accompanying drawings, there is a hot wastewater storage tank 10 for temporarily storing wastewater (hot wastewater) having a high temperature generated from an industrial body and sending and receiving hot wastewater of the hot wastewater storage tank 10 A water circulation pipe 21 and a water return pipe 22 connected to the water pipe 21 and the water return pipe 22 and connected to the first circulation water pipe 21 including one face 31 of the heat exchange plate 30 through the hot water pipe, (20)

상기 온열폐수와 열교환된 온수를 임시 보관하는 온수저장탱크(40)가 있고 상기 온수저장탱크(40)의 열교환수(온열폐수와 열교환되는 냉수를 말함)를 송수하고 환수하는 제2송수관(51)과 제2환수관(52)이 있으며 상기 제2송수관(51)과 제2환수관(52)에 연결되어 열교환수가 경유하는 열교환판(30)의 이면(32)을 포함한 제2순환수로(50)와, A hot water storage tank 40 for temporarily storing hot water exchanged with the hot wastewater and a second water supply pipe 51 for sending and receiving heat exchange water (cold water to be heat-exchanged with hot wastewater) of the hot water storage tank 40, And a second circulating water pipe 52 connected to the second water pipe 51 and the second water pipe 52 and including a rear surface 32 of the heat exchange plate 30 passing through the heat exchange water, 50,

상기 송수관(21) 내지는 환수관(22)에 연결되어 상기 온열폐수저장탱크(10)의 온열폐수를 순환시키는 제1모터펌프(60)와,A first motor pump (60) connected to the water pipe (21) or the water return pipe (22) for circulating the hot wastewater of the hot water storage tank (10)

상기 제2송수관(51) 내지는 제2환수관(52)에 연결되어 상기 온수저장탱크(40)의 열교환수(온열폐수와 열교환하는 냉수임)를 순환시키는 제2모터펌프(70)를 포함한 구성에 있어서,And a second motor pump 70 connected to the second water supply pipe 51 or the second water return pipe 52 for circulating the heat exchange water (cold water for heat exchange with the hot wastewater) of the hot water storage tank 40 In this case,

이와 같은 구성의 실시예를 설명하면 다음과 같다.An embodiment of such a construction will be described as follows.

상기 구성의 상태에서 온수저장탱크(40)에 있는 냉수(이 냉수는 수도관과 연결될 수 있음)가 제2송수관(51)을 통해 송수되어 열교환판(30)의 이면(32)을 경유하여 다시 제2환수관(52)을 통해 온수저장탱크(40)로 유입된다. 이와 같은 과정이 제2모터펌프(70)에 의해 지속적으로 순환을 반복한다.The cold water (which can be connected to the water pipe) in the hot water storage tank 40 is sent through the second water pipe 51 and is supplied again through the back surface 32 of the heat exchange plate 30 2 water pipe (52). This process is continuously repeated by the second motor pump 70.

온열폐수저장탱크(40)에 있는 온열은 송수관(21)을 통해 송수되어 열교환판(30)의 일면(31)을 경유하여 다시 환수관(22)을 통해 온열폐수저장탱크(10)로 유입된다. 이와 같은 과정이 제1모터펌프(60)에 의해 지속적으로 순환을 반복한다.The heat in the hot wastewater storage tank 40 is supplied to the hot wastewater storage tank 10 through the water return pipe 22 via one side 31 of the heat exchange plate 30 . This process is continuously repeated by the first motor pump 60.

그러므로 온열폐수저장탱크(40)에 임시 보관중인 온열이 수도관(미도시)의 냉수와 열교환되어 온수저장탱크(40)에 저장된다.Therefore, the heat being temporarily stored in the hot wastewater storage tank 40 is heat-exchanged with the cold water of the water pipe (not shown) and is stored in the hot water storage tank 40.

이와 같이 방법으로 열교환을 장기간 하다보면 제1순환수로(20)When the heat exchange is performed for a long time in this way,

내부에 온열폐수에 혼합된 이물질이 쌓이게 된다.The foreign matter mixed in the hot wastewater is accumulated inside.

따라서 다음은 제1순환수로(20) 내부에 쌓인 이물질을 외부로 배출하기 위해 구성을 재차 살펴보고 그에 따른 실시예를 설명하고자 한다.Therefore, the following description will be made on the configuration of the first circulating water passage 20 for the purpose of discharging the foreign substances accumulated inside thereof.

송수관(21)에 수로(유로)의 방향을 전환하는데 사용하는 3방밸브(100)를 설치하여 제1순환수로(20)의 내부를 세척할 경우 온열폐수저장탱크(10)로부터 열교환판(30)으로 이동하는 수로를 차단하고 동시에 열교환판(30)으로부터 역으로 순환되는 세척수를 외부로 배출하도록 개방하며,When the three-way valve 100 used to switch the direction of the water channel is installed in the water pipe 21 to clean the inside of the first circulation water passage 20, the heat exchange water from the hot water storage tank 10 to the heat exchange plate 30, and at the same time is opened to discharge the washing water circulated back from the heat exchange plate 30 to the outside,

상기 환수관(22)은 상기 환수관(22)에 수로(유로)의 방향을 전환하는데 The water return pipe 22 switches the direction of the water channel (flow channel) to the water return pipe 22

사용하는 3방밸브(101)를 설치하여 열교환판(30)으로부터 온열폐수저장탱크(10)로 이동하는 수로를 차단하고 동시에 온수저장탱크(40)와 연결된 세척수배관(53)의 수로를 개방하여 세척수를 환수관(22)을 통해 열교환판(30)으로 이동하도록하며The three-way valve 101 to be used is installed to block the water channel from the heat exchange plate 30 to the hot wastewater storage tank 10 and to open the water channel of the wash water pipe 53 connected to the hot water storage tank 40 The washing water is moved to the heat exchange plate 30 through the water return pipe 22

상기 제2순환수로(50)은 상기 제2송수관(51) 내지는 상기 제2환수관(52)에 수로(유로)를 차단하거나 개방하는 개폐밸브(102)를 설치하여 제1순환수로(20)의 내부를 세척할 경우 상기 제2순환수로(50)의 수로를 차단하는 구성이다.The second circulating water path 50 is provided with an on-off valve 102 for blocking or opening a water path (passage) to the second water pipe 51 or the second water pipe 52, 20, the water path of the second circulating water path 50 is blocked.

이와 같은 구성의 실시예를 설명하고자 한다.An embodiment of such a configuration will be described.

구성에서 알 수 있듯이 3방밸브(100,101)와, 개폐밸브(102)에 전원을 공급하면 송수관(21)에 장착된 3방밸브(100)는 온열폐수저장탱크(10)로부터 열교환판(30)으로 이동하는 수로를 차단하고 동시에 열교환판(30)으로부터 역으로 순환되는 세척수를 외부로 배출하도록 개방한다.The three-way valve 100 installed in the water pipe 21 is connected to the heat exchange plate 30 from the hot wastewater storage tank 10 by supplying power to the three-way valves 100 and 101 and the on- And at the same time opens the circulating washing water from the heat exchange plate 30 to the outside to discharge the washing water to the outside.

그리고 또 다른 3방밸브(101)는 온열폐수저장탱크(10)로 이동하는 수로를 차단하고 동시에 온수저장탱크(40)와 연결된 세척수배관(53)의 수로를 개방한다.The other three-way valve 101 blocks the water passage to the hot wastewater storage tank 10 and at the same time opens the water passage of the wash water pipe 53 connected to the hot water storage tank 40.

그리고 개폐밸브(102)를 설치하여 제1순환수로(20)의 내부를 세척할 경우 상기 제2순환수로(50)의 수로를 차단한다.When the inside of the first circulating water passage 20 is cleaned by providing the on-off valve 102, the water passage of the second circulating water passage 50 is blocked.

이와 같이 각각의 밸브를 조작한 상태에서 온수저장탱크(40)에 저장된 온수를 제2송수관(51)을 통해 송수하면 송수된 온수는 세척수배관(53)과 환수관(22)을 지나 열교환판(30)의 일면(31)을 경유한 후 송수관(21)을 지나 외부로 배출된다.When the hot water stored in the hot water storage tank 40 is sent through the second water pipe 51 in the state where the respective valves are operated as described above, the hot water sent and received passes through the washing water pipe 53 and the water return pipe 22, 30 and then discharged through the water pipe 21 to the outside.

상기 배출시간은 미리 설정해둔 시간이 되면 각각의 밸브들(100,101,102)이 원위치되어 온열폐수와 냉수가 열교환상태가 된다.When the discharge time reaches a preset time, the valves 100, 101, and 102 are returned to the heat exchange state between the hot wastewater and the cold water.

상술한 바와 같이 온수를 세척수배관(53)을 통해 세척수배관(53)과 연결시킨 환수관(22)에 역방향으로 흘려보내 열교환판(30)의 일면(31)과 송수관(21)을 세척한다. 즉 정방향으로 인해 흡착된 이물질을 역방향으로 흐르는 온수에 의해 제거된다.The hot water is flowed in the opposite direction to the water return pipe 22 connected to the washing water pipe 53 through the water pipe 53 to wash the water pipe 21 and the one surface 31 of the heat exchange plate 30 as described above. That is, the foreign matter adsorbed in the forward direction is removed by the hot water flowing in the reverse direction.

여기서 참고로, 본원의 경험에 의하면 제1순환수로(20)의 내부에 흐르는 온열폐수가 정방향으로 이동하는 과정에 제1순환수로(20) 내부의 모서리 부분에 흡착된다. 이러한 흡착물은 온수를 역으로 흘려보내면 제거되는 것을 확인할 수 있었다. 이를 감안하여 이 건을 살펴보기 바란다.In this regard, according to the experience of the present application, the hot wastewater flowing in the first circulation water passage 20 is adsorbed at the corners inside the first circulation water passage 20 in the forward movement direction. It was confirmed that the adsorbate was removed by flowing the hot water backward. Take this into consideration.

이상과 같은 방법의 제어는 컨트롤장치에 미리 입력한 설정한 시간이 되면 제1순환수로(20) 세척시간으로 간주하고 각각의 밸브들(100,101,102)을 제어하여 세척하는 것이다.The control of the above-described method is to control the respective valves 100, 101, and 102 by cleaning the first circulation water 20 as the cleaning time when the preset time is inputted to the control device.

다음은 탁도센서에 의해 송수관(21) 내지는 환수관(22)내부를 관찰하고자 한다.Next, the inside of the water pipe 21 or the water return pipe 22 is to be observed by the turbidity sensor.

구성, 송수관(21) 내지는 환수관(22)에 우회배관(80)을 설치하여 상기 송수관(21) 내지는 환수관(22)내에 흐르는 온열폐수가 상기 우회배관(80)을 경유하도록 하되 상기 우회배관(80)외부에 상기 우호배관(80) 내부의 탁도를 감지하는 탁도감지센서(85)를 설치하는 구성이다.A bypass pipe 80 is provided in the water pipe 21 or the water pipe 22 so that the hot water flowing in the water pipe 21 or the water pipe 22 can pass through the bypass pipe 80, And a turbidity detection sensor 85 for detecting the turbidity inside the friendly pipe 80 is installed outside the air conditioner 80.

이와 같은 구성의 실시예를 설명하면 다음과 같다.An embodiment of such a construction will be described as follows.

탁도감지센서(85)는 투명관으로 이루어진 우회배관(80)을 원주연 양단에 발신용 레이저부(86)와 수신용 레이저(87)를 갖도록 하여 빛을 이용하여 우회배관 내부 벽면에 흡착된 이물질의 탁도를 감지하는 것이다.The turbidity detection sensor 85 is provided with a bypass pipe 80 made of a transparent tube having a laser part 86 for receiving and a receiving laser 87 at both ends of the circumference of the circumference to detect foreign matter adsorbed on the inner wall surface of the bypass pipe Of turbidity.

따라서 미리 설정한 탁도가 감지되면 제1순환수로(20) 세척단계로 간주하고 각각의 밸브들(100,101,102)을 제어하여 세척을 진행한다.Accordingly, when the predetermined turbidity is detected, the first circulation water 20 is regarded as the cleaning step, and the valves 100, 101, and 102 are controlled to perform cleaning.

상기 탁도감지센서에 대한 기술적인 내용은 대한민국 특허청 등록번호 제10-1396390호에 상세하게 설명되어 있어 이에 대한 상세한 설명은 생략한다.Technical details of the turbidity sensor are described in Korean Patent Registration No. 10-1396390, and a detailed description thereof will be omitted.

상기와 같이 세척이 진행되면 송수관(21) 내부와 우회배관(80) 내부에 온수이면서 깨끗한 물이 흐르므로 그 물에 의해 이물질이 제거되면서 발신용 레이저부(86)의 빛이 다시 우회배관(80)을 통과하여 수신용 레이저(87)에 도달하게된다.When washing is performed as described above, hot water and clean water flow into the water pipe 21 and the bypass pipe 80, so that the foreign matter is removed by the water, and the light of the laser part 86 for the foot is again directed to the bypass pipe 80 To reach the receiving laser 87.

이와 같이 발신용 레이저부(86)의 빛이 수신용 레이저(87)에 이르게되면 컨트롤방법에 따라 각각의 밸브들(100,101,102)이 원위치되어 온열폐수와 냉수가 열교환 상태가 된다.When the laser beam emitted from the laser beam source 86 reaches the receiving laser 87, the valves 100, 101, and 102 return to the heat exchange state according to the control method.

상기 우회배관을 신설하여 탁도를 감지함으로서 A/S 발생시 우회배관(80)만 분리하면 가능함으로 편리하다.It is convenient because it is possible to separate only the bypass pipe 80 when the A / S is generated by detecting the turbidity by newly installing the bypass pipe.

또 온수폐수 송수에 다른 유속이 송수관(21)과 우회배관(80)으로 분산되므로 In addition, since different flow rates are distributed to the water pipe (21) and the bypass pipe (80)

유속이 느려 온수폐수 탁도를 측정하는데 효과적이라 할 수 있다.It can be said that it is effective to measure turbidity of hot water wastewater due to slow flow rate.

다음은 우회배관 내부를 브러시를 이용하여 청소하고자 한다.Next, we want to clean the inside of the bypass pipe using a brush.

구성, 우회배관(80) 내부에 상기 우회배관(80) 내부벽을 닦을수 있는 브러시(81)를 내장하고 상기 브러시(81)는 밀대(82) 일측이 연결되고 상기 밀대(82) 타측은 상기 우회배관(80)의 길이방향을 지나 우회배관(80)의 길이방향 외부에 위치한다. And a brush 81 for wiping the inner wall of the bypass pipe 80 is installed inside the bypass pipe 80. The brush 81 is connected to one side of the push rod 82 and the other side of the push pin 82 is connected to the bypass Is located outside the longitudinal direction of the bypass pipe (80) through the longitudinal direction of the pipe (80).

이와 같은 구성의 실시예를 설명하고자 한다.An embodiment of such a configuration will be described.

우회배관(80)은 투명배관이므로 외부에서 우회배관(80) 내부 벽에 흡착된 이물질을 확인할 수 있어 관리자가 인위적으로 밀대(82)를 이용하여 내부 벽을 닦아주면 된다. 만약 우회배관(80) 내부 벽에 흡착된 이물질을 닦아주지 않을 경우 Since the bypass piping 80 is a transparent piping, it is possible to confirm the foreign matter adsorbed to the inner wall of the bypass piping 80 from the outside, so that the manager can artificially wipe the inner wall using the push rod 82. If the foreign matter adsorbed on the inner wall of the bypass pipe 80 is not wiped off

탁도감지센서(85)가 오작동을 일으킬 수 있다.The turbidity detection sensor 85 may malfunction.
