폐수열 열교환기의 세척 시스템{PANEL FOR FLAT PLATE HEAT EXCHANGER}[0001] PANEL FOR FLAT PLATE HEAT EXCHANGER [0002]

본 발명은 폐수열 열교환기의 세척 시스템에 관한 것으로, 보다 상세하게는 방류되는 폐수의 열을 회수하는 열교환기를 세척하기 위한 폐수열 열교환기의 세척 시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning system for a waste heat heat exchanger, and more particularly, to a cleaning system for a waste heat heat exchanger for cleaning a heat exchanger that recovers the heat of discharged wastewater.

일반적으로 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.As generally shown in Figs. 1 to 3, the plate heat exchanger 1 is excellent in performance for use in high-temperature and low-temperature heat exchange between two fluids, and is widely used in construction, industry, food factory, And a heat plate for heat transfer of the high temperature fluid of the fluid to the low temperature fluid is fixed inside and the external both sides of the heat exchanger are maintained by using the front fixing plate 11 and the rear fixing plate 12 , And to 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 형성되므로서 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 plateaux 4, 4 ', 4 "and 4 "' on the upper and lower surfaces, respectively, A rubber packing (5) for blocking hot water and cold water introduced into the water holes (4, 4 ') is placed on the front and back edges of the heat exchange plate (2).

상기 열교환판(2)은 상기 고무패킹(2)을 맞닺는 형태로서 적층구성하여 복수의 열 교환실(A)을 형성한다.The heat exchange plate (2) is formed by laminating the rubber packing (2) in the form of being fitted 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 흐르로도록 하여 열을 교환한다. The heat exchange plate (2) exchanges heat such that hot water flows on the front surface and cold water flows on the back surface, for example.

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 온수내지는 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.

전면 고정판(50)에 연결된 상측온수배관(40), 상측냉수배관(40'), 하측온수배관(40") 하측냉수배관(40"')에 각각 장착한 제1개폐밸브(80),제2개폐밸브(81),제3개폐밸브(82),제4개폐밸브,(84)중 외부에서 미도시한 모터펌프로 유입되는 냉수가 유입되는 상측냉수배관에 장착된 제2개폐밸브(81)를 제외한 나머지 제1개폐밸브(80),제3개폐밸브(82),제4개폐밸브,(84)는 온수나 냉수가 흐르지 않도록 밀폐한다.A first open / close valve 80 mounted on the upper side hot water pipe 40 connected to the front fixing plate 50, the upper side cold water pipe 40 ', the lower side hot water pipe 40 "and the lower side cold water pipe 40" A second on-off valve 81 (see FIG. 1) mounted on the upper side cold water pipe into which the cold water flowing into the motor pump not shown from the outside among the two open / close valve 81, the third open / close valve 82, The third open / close valve 82, and the fourth open / close valve 84 except for the first and second open / close valves 80, 84 are closed to prevent hot water or cold water from flowing.

그리고 후방 고정판(51) 하단에 해당하며 온수유입수로공(30)과 관통된 냉수개폐밸브(87)를 개방하면 온수유입수로공(30)의 수로가 개방된다.When the cold water opening / closing valve 87 corresponding to the lower end of the rear fixing plate 51 and opened through the hot water inflow hole 30 is opened, the channel of the hot water inflow hole 30 is opened.

그리고 냉수경로배관(70)에 장착한 제6개폐밸브(86)를 개방한다(도 4,6참조)And the sixth on-off valve 86 mounted on the cold water path pipe 70 is opened (see Figs. 4 and 6)

이와 같이 다수의 밸브를 개방하거나 밀폐하여 온수 유입을 차단하고 냉수의 수로경로를 달리한 다음 냉수를 냉수유입수로공(30')으로 모터펌프를 통해 유입하면 냉수는 열교환판의 전면과 이면 그리고 냉수개폐밸브(87)를 지나 외부로 배출된다.(도 8참조)When the cold water is introduced into the cold water inflow hole (30 ') through the motor pump, the cold water passes through the front and back sides of the heat exchange plate and the cold water And is discharged to the outside through the opening / closing valve 87 (see FIG. 8)

이와 같은 과정에 온수에 의해 온수유입수로공(30)과 온수배출수로공(30")에 쌓인 이물질이 외부로 배출되는 것이다.In this process, foreign substances accumulated in the hot water inflow hole 30 and the hot water discharge hole 30 "are discharged to the outside by hot water.
