Description

흡수식 히트펌프를 이용한 지역난방수 공급 시스템{Local Heating Water Feeding System using Absorbing Type Heat Pump }Local Heating Water Feeding System using Absorbing Type Heat Pump}

본 발명은 흡수식 히트펌프를 이용한 지역난방수 공급 시스템에 관한 것으로서, 더욱 상세하게는 각종 냉각시스템 및 냉각탑에 의해 버려지는 열원을 회수하여 지역난방수의 열원인 스팀량을 대폭 줄이고, 냉각수의 열을 히트펌프의 열원으로 사용함으로써 냉각탑을 사용하지 않아 환경오염방지 및 에너지의 절감을 이룰 수 있도록 한 것이다. The present invention relates to a district heating water supply system using an absorption heat pump, and more particularly, to recover heat sources discarded by various cooling systems and cooling towers, thereby greatly reducing the amount of steam, which is the heat source of district heating water, and heating the heat of cooling water. By using it as a heat source of the pump, the cooling tower is not used to prevent environmental pollution and to save energy.

종래의 지역 난방수 공급시스템은 도 1에 도시된 바와 같이, 예를 들어 복합화력발전소의 보일러(도시되지 않음)에서 연료의 소모에 의해 생성된 스팀이 터빈(10)을 거치면서 전기를 생산하는데 필요한 일을 하게되고, 이 터빈(10)에서 나온 스팀은 배관(11)을 통해 열교환기(20)를 거쳐서 공급배관(12)을 통해 다시 보일러로 환수되며, 이러한 과정을 반복함으로써 지속적인 발전기능을 유지하는 것이다. In the conventional district heating water supply system, as shown in FIG. 1, for example, steam generated by fuel consumption in a boiler (not shown) of a combined cycle power plant generates electricity while passing through a turbine 10. When necessary, the steam from the turbine 10 is returned to the boiler through the supply pipe 12 through the heat exchanger 20 through the pipe (11), and by repeating this process to maintain a continuous power generation function To keep.

또한, 열교환기(20)에는 지역난방탱크(30)로부터 공급되는 온수(약 60도)가 열교환기(20)를 통과하여 공급되는 스팀과 열교환된 다음, 지역난방 온수 출구부(40)를 통해 각 시설물(아파트 등)에 난방공급을 하는 것이다. In addition, in the heat exchanger 20, hot water (about 60 degrees) supplied from the district heating tank 30 is heat-exchanged with steam supplied through the heat exchanger 20, and then through the district heating hot water outlet 40. Each facility (apartment, etc.) is supplied with heating.

또한, 복수기(50)에는 복수기(50)의 냉각을 위해 냉각수가 순환되는데, 복수기(50)를 거친 냉각수가 순환배관(51)을 통해 냉각탑(60)을 통과하면서 대기중으로 열을 방출시키고, 순환배관(61)을 통해 다시 복수기(50)로 공급된다. In addition, the condenser 50 has a cooling water circulated for cooling the condenser 50, the cooling water passing through the condenser 50 passes through the cooling tower 60 through the circulation pipe 51 to release heat to the atmosphere, and circulation The pipe 61 is again supplied to the condenser 50.

또한, 여름철과 같이 난방을 하지 않는 경우에는, 터빈(10)으로부터 나오는 스팀을 배관(11)을 거치지 않고, 별도 연결된 추기관(13)을 통해 공급되도록 하며, 이 추기관(13)은 복수기(50)를 거쳐서 펌프(P)에 의해 다시 보일러로 환수된다. In addition, in the case of not heating like summer, the steam coming from the turbine 10 is supplied through a separately connected extraction pipe 13 without passing through the pipe 11, and the extraction pipe 13 is a condenser ( 50) is returned to the boiler by the pump (P).

여기서, 종래의 지역난방 공급 시스템은 터빈(10)으로부터 나오는 스팀을 열교환기(20)로 통과시키면서 지역난방탱크(30)로부터 공급되는 온수와 열교환하여 승온시켜서 지역 난방수로 공급하기 때문에, 화력발전소의 발전능력을 저하시키는 요인으로 작용하였다.Here, the conventional district heating supply system heats and heats up the hot water supplied from the district heating tank 30 while passing steam from the turbine 10 to the heat exchanger 20 to supply the district heating water. It acted as a factor to lower the power generation capacity of.

다시 말해서, 지역난방수 100을 얻고자 한다면, 종래에는 터빈(10)으로부터 나오는 스팀의 열원을 100 이상(열교환기(20)에서의 열교환효율을 고려하면 110 이상이 되어야 함)이 필요하기때문에, 그 만큼 열에너지 손실이 많아 발전소의 발전능력을 저하시키는 요인으로 작용하는 것이다.  In other words, if the district heating water 100 is to be obtained, since the heat source of the steam from the turbine 10 conventionally requires 100 or more (considering the heat exchange efficiency in the heat exchanger 20 should be 110 or more), As much heat energy is lost, it acts as a factor to lower power generation capacity of power plant.

더욱이, 복수기(50)의 냉각을 위해 냉각탑(60)을 가동하여 열을 방출시키는데, 이 냉각탑(60)은 통상 예를 들어 아파트 단지에 설치되는 경우, 뜨거운 열기를 방출하기 때문에 열손실을 초래하고, 또한 레지오넬라균과 소음을 유발하여 주변 주민들에게 피해를 줄 수 있다.Moreover, the cooling tower 60 is operated to release heat for cooling the condenser 50, which, when installed in an apartment complex, for example, causes heat loss because it emits hot heat. It can also cause legionella and noise, causing damage to nearby residents.

또한, 냉각탑(60)을 사용하면 백연 현상이 발생하는데, 이 백연은 배출되는 배출공기가 낮은 온도의 대기와 접촉할 때, 배출공기 내의 수증기가 이슬점(dew point) 이하로 내려감으로써, 배출공기가 미세한 액적 상태로 되어 흰연기로 보이는 현상이다. In addition, when the cooling tower 60 is used, a white smoke phenomenon occurs. When the exhaust air is discharged and comes into contact with a low temperature atmosphere, the water vapor in the exhaust air falls below the dew point. It is a phenomenon in which white droplets appear as fine droplets.

이러한 백연은 일반적으로 인체에 유해한 성분을 포함하고 있지는 않으나, 미관상 유해한 성분을 포함하고 있는 것으로 보일 수 있고, 주변 시계에 방해가 되므로 백연의 효과적인 제거가 요구된다. Such white smoke does not generally contain harmful ingredients, but it may appear to contain aesthetically harmful ingredients, which may interfere with the surrounding field of vision, thus requiring effective removal of white lead.

이에 본 발명은 상기와 같은 종래의 제반 문제점을 해결하기 위해 발명된 것으로서, 본 발명에서 해결하고자 하는 과제는 종래의 냉각탑을 사용하지 않으면서 냉각탑을 통해 버려지는 열원을 회수하여 지역 난방수를 승온시킬 수 있도록 함으로써 에너지 절감을 이룰 수 있도록 한 것이다. The present invention has been invented to solve the above-mentioned conventional problems, the problem to be solved in the present invention is to recover the heat source is discarded through the cooling tower without using the conventional cooling tower to increase the local heating water By doing so, energy savings can be achieved.

And a portion of the steam from the turbine 10 is returned to the boiler through the bypass pipe (17) (17a).

또한, 본 발명은 도 4에 도시된 바와 같이, 지역난방 탱크(30)로부터 배관(31)을 통해 흡수기(120)를 거쳐서 응축기(130)로 가는 지역난방수가 응축기(130)로 가기전에, 한번 더 가열되도록 보조 열교환기(170)를 더 구비할 수 있다.In addition, the present invention, as shown in FIG. 4, before the district heating water going to the condenser 130 from the district heating tank 30 through the pipe 31 through the absorber 120 to the condenser 130, once Auxiliary heat exchanger 170 may be further provided to further heat.

재생기(110)를 거치면서 배관(112)를 통해 나오는 고온의 진한용액이 용액열교환기(150)를 거쳐서 다시 흡수기(120)로 가게 되는데, 이때 보조 열교환기(170)를 거치도록 함으로써 흡수기(120)를 통과하는 지역난방수가 한번 더 가열된 상태로 응축기(130)로 유입되어 다시 가열되도록 한 것이다. The high temperature concentrated solution coming out of the pipe 112 while passing through the regenerator 110 goes back to the absorber 120 through the solution heat exchanger 150, at which time the absorber 120 passes through the auxiliary heat exchanger 170. The district heating water passing through) is introduced into the condenser 130 while being heated once again to be heated again.

더욱이, 용액 열교환기(150)의 용량(열교환 용량)이 미리 설정된 경우, 필요한 지역난방수 온수를 얻기 위해서, 보조열교환기(170)의 용량을 조절하여 설치하도록 한 것이다. In addition, when the capacity (heat exchange capacity) of the solution heat exchanger 150 is set in advance, in order to obtain the required district heating water, the auxiliary heat exchanger 170 is adjusted to be installed.

또한, 용액 열교환기(150)의 용량을 작게 하는 경우, 상대적으로 보조열교환기(170)의 열교환능력을 크게 설정하여 설치할 수 있으므로, 그에따라 흡수기(120)를 거치는 지역난방수가 더 많은 열원을 얻어서 응축기(130)를 거치면서 재차 열원을 얻어 승온이 되어 배출되도록 할 수 있다. In addition, when the capacity of the solution heat exchanger 150 is reduced, since the heat exchange capacity of the auxiliary heat exchanger 170 can be set relatively large, the district heating water passing through the absorber 120 can be obtained accordingly. While passing through the condenser 130, it is possible to obtain a heat source again to be heated up and discharged.

다시 말해서, 원하는 조건의 지역난방수 온도에 따라 본 발명에 따른 흡수식 히트펌프(100)의 열교환능력을 조절하여 사용할 수 있는 것이다. In other words, the heat exchange capacity of the absorption type heat pump 100 according to the present invention can be used according to the district heating water temperature under desired conditions.

상기 보조열교환기(170)는 흡수기(120)와 배관(123)을 통해 연결되고, 배관(171)을 통해 응축기(130)와 연결된다. The auxiliary heat exchanger 170 is connected to the absorber 120 and the pipe 123, and is connected to the condenser 130 through the pipe 171.
