Description

증기 보일러의 환수장치 {COOLING WATER DRAIN DEVICE OF STEAM BOILER}Return to Steam Boiler {COOLING WATER DRAIN DEVICE OF STEAM BOILER}

본 발명은 증기 보일러의 환수장치에 관한 것이며, 상세하게는 이용기기에서 사용하고 남은 배열을 응축시켜 그 응축수를 증기 보일러에 환수할 때의 폐열회수장치에 관한 것이다.The present invention relates to a recovery device for a steam boiler, and more particularly, to a waste heat recovery device when condensing the remaining arrangement used in a user equipment to return the condensed water to the steam boiler.

주지하는 바와 같이 보일러 특히 증기 보일러는 보일러에서 생성한 증기를 난방장치, 각종 작업기계 등의 이용기기에 공급하여 그 목적에 부합되게 사용하고, 사용하고 남은 배열을 응축한 후 그 응축수를 응축수 탱크(드레인 탱크)에 저장하였다가 증기 보일러에 관수로서 재공급함으로써 에너지를 절감하고 있다.As is well known, boilers, especially steam boilers, supply steam generated by boilers to equipment used for heating devices and various working machines, and use them in accordance with their purpose. Energy is saved by storing it in a drain tank and resupplying it to the steam boiler as water.

종래의 증기 보일러의 환수장치는 도 2에 도시한 바와 같이 증기 보일러(1)에 설치한 증기 공급관(2)을 난방장치, 각종 작업기계, 사우나 등의 이용기기(3)에 연결하고, 상기 이용기기(3)에 설치한 배출관(4)의 도중에 증기트랩(5)을 설치함과 동시에 배출관(4)의 타단을 응축수 탱크(6)에 연결하며, 상기 응축수 탱크(6)와 증기 보일러(1) 사이에 펌프(8)가 부설된 환수관(7)을 연결한 것이다.In the conventional steam boiler return device, as shown in FIG. 2, the steam supply pipe 2 installed in the steam boiler 1 is connected to a heating device, various working machines, a user equipment such as a sauna, and the like. The steam trap 5 is installed in the middle of the discharge pipe 4 installed in the apparatus 3 and the other end of the discharge pipe 4 is connected to the condensate tank 6, and the condensate tank 6 and the steam boiler 1 ) Is connected to the return pipe (7) in which the pump (8) is installed.

한편 상기 응축수 탱크(6)에는 플로트 밸브(9)를 설치하고, 상기 플로트 밸브(9)에 급수관(10)을 연결하여 응축수 탱크(6)에 항상 일정 수면의 급수를 저장하며, 또한 상기 응축수 탱크(6)의 상면에는 배기관(11)을 설치하며, 상기 증기트랩(5)에는 바이패스관(12)을 설치한 것이다.On the other hand, the condensate tank (6) is provided with a float valve (9), the water supply pipe (10) is connected to the float valve (9) to always store a constant water supply in the condensate tank (6), the condensate tank Exhaust pipe 11 is provided on the upper surface of (6), and the bypass pipe 12 is provided on the steam trap (5).

상기한 증기 보일러의 환수장치는 이용기기에서 그 목적에 부합되게 사용하고 남은 배열인 증기와 응축수를 증기트랩(5)에서 분리시킨 후 응축수만 응축수 탱크(6)에 저장하였다가 증기 보일러(1)에 관수가 부족할 경우 펌프(8)를 구동하여 증기 보일러(1)에 공급하는 것이다.The return device of the steam boiler is used in accordance with the purpose in the equipment used to separate the steam and condensed water remaining in the steam trap (5) after storing only the condensate in the condensate tank (6) and then steam boiler (1) If the lack of watering is to drive the pump (8) to supply to the steam boiler (1).

그러나 상기한 증기 보일러의 환수장치는 증기트랩(5)에서 증기와 응축수를 분리하여 응축수만을 배출하는 것이지만 증기트랩(5)의 밸브와 밸브시트의 접촉상태가 양호하지 못하거나 사용에 의하여 밸브 등이 손상될 경우에는 증기가 응축수에 혼입되며, 상기 증기는 응축수의 온도가 고온임으로 응축되지 못하고 응축수 탱크(6)의 상부에 성치한 배기관(11)으로 대기중에 방출되는 것임으로 열손실을 초래하는 것이다.However, the return device of the steam boiler is to discharge only the condensate by separating the steam and condensate in the steam trap 5, but the contact state between the valve and the valve seat of the steam trap 5 is not good or the valve is not If damaged, steam is mixed into the condensate, which causes heat loss because the condensate is not condensed due to the high temperature and is discharged into the atmosphere through the exhaust pipe 11 placed above the condensate tank 6. .

그리고 증기트랩(5)에서 증기와 응축수가 분리될 때 증기트랩(5)에 내장된 밸브는 간헐적으로 개방되는 것이기 때문에 이용기기(3)와 증기트랩(5) 사이에 증기와 응축수의 정체현상이 생김으로 이용기기에서의 방열이 저조하게 되며, 상기와 같이 이용기기에서 방열이 저조하면 이용기기의 사용초기 또는 사용중에 이용기기의 온도가 낮게 되어 이용목적에 부적합한 현상이 생기는 것이다.When the steam and the condensate are separated from the steam trap 5, the valve built in the steam trap 5 is intermittently opened, so that the phenomenon of congestion between the steam and condensate between the user device 3 and the steam trap 5 may occur. As a result, the heat dissipation in the user equipment is low, and if the heat dissipation in the user equipment is low as described above, the temperature of the user equipment becomes low during the initial use or during the use of the user equipment, which is not suitable for the purpose of use.

상기와 같이 이용목적에 부적합한 현상이 생기면 이를 해결하기 위하여 증기트랩(5)을 바이패스시켜 설치한 바이패스관(12)의 밸브를 개방하여 증기를 응축수 탱크(6)에 직접 배출하고 있음으로 이 경우에는 응축수 탱크(6)에 다량의 증기가 배출되어 열손실이 더욱더 커지게 되는 것이다.As described above, in order to solve this problem, the valve of the bypass pipe 12 installed by bypassing the steam trap 5 is bypassed to discharge the steam directly to the condensate tank 6. In this case, a large amount of steam is discharged to the condensate tank 6 so that the heat loss is even greater.

본 발명은 상기한 실정을 감안하여, 응축수 탱크에 유입되는 증기를 신속히 응축시켜 열손실을 줄일 수 있고, 또한 온수를 부수적으로 생성할 수 있는 증기 보일러의 환수장치를 제공하는 것을 목적으로 한다.In view of the above circumstances, an object of the present invention is to provide a steam boiler returning device capable of rapidly condensing steam introduced into a condensate tank to reduce heat loss and additionally generating hot water.

미설명부호 27, 27'는 밸브이다.Reference numerals 27 and 27 'are valves.

이상과 같은 본 발명은 이용기기(3)에 공급된 증기는 난방 등의 용도에 사용하고 증기트랩(5)에서 응축수가 분리된 후 가열관(33)을 경유하여 응축수 탱크(6)에 유입 저장되며, 상기 저장된 응축수는 증기 보일러(1)에 관수가 부족할 경우 펌프(8)를 구동하여 증기 보일러(1)에 공급하는 것이다.In the present invention as described above, the steam supplied to the user equipment 3 is used for the purpose of heating and the like, and after the condensate is separated from the steam trap 5, it flows into the condensate tank 6 through the heating tube 33. The stored condensate is to supply the steam boiler 1 by driving the pump 8 when the steam boiler 1 lacks water.

상기와 같이 증기트랩(5)에서 증기와 응축수가 분리될 때 그 분리가 양호하지 못하면 증기가 응축수와 함께 응축수 탱크(6)에 유입되는 바, 상기와 같이 증기가 응축수에 혼입된 상태로 응축수 탱크(6)로 유입될 때 그 혼입량이 작을 때에는 연결관(26)에 설치한 밸브(27')는 폐쇄하고 제 1 출탕관(21)에 설치한 밸브(27)는 개방한 후 온수가열 열교환기(20)에 급수관(10)을 통하여 냉수를 공급하면 온수가열 열교환기(20)를 경유하는 냉수와 응축수 탱크(6) 내의 응축수가 열교환함에 따라 냉수는 가열되어 온수가 생성되고 응축수는 냉각됨과 동시에 상기 냉각된 응축수 및 온수가열 열교환기(20)를 경유하는 냉수 또는 온수에 의하여 응축수 탱크(6)에 유입되는 증기는 즉시 응축되기 때문에 증기가 종래와 같이 배기관(11)으로 배출되지 않음으로 종래 폐기하던 증기의 보유열을 온수생성에 활용할 수 있고, 온수가열 열교환기(20)에서 생성된 온수는 제 1 온수 출탕관(21)을 경유하여 온수 저장탱크(22)에 저장하였다가 필요한 용도 예를 들어 난방용, 급탕용 또는 보일러의 급수용으로 사용하는 것이다.When the steam and condensate is separated from the steam trap 5 as described above, if the separation is not good, the steam is introduced into the condensate tank 6 together with the condensate. As described above, the condensate tank is mixed with the condensate. (6) When the mixing amount is small, the valve 27 'installed in the connecting pipe 26 is closed and the valve 27 installed in the first tapping pipe 21 is opened, and then the hot water heating heat exchanger is opened. When cold water is supplied to the water supply pipe (10) through the water supply pipe (10), as the cold water passing through the hot water heat exchanger (20) and the condensed water in the condensate tank (6) heats, the cold water is heated to generate hot water, and the condensate is cooled. Since the steam flowing into the condensate tank 6 by the cold or hot water passing through the cooled condensate and hot water heating heat exchanger 20 is immediately condensed, the steam is not discharged to the exhaust pipe 11 as in the prior art and thus disposed of. Sickness The retaining heat of the can be utilized to generate hot water, the hot water generated in the hot water heating heat exchanger (20) is stored in the hot water storage tank (22) via the first hot water tapping pipe (21), for example, for heating purposes It is used for water supply or water supply of boiler.

그리고 증기트랩(5)에서 증기와 응축수가 분리될 때 그 분리가 양호하지 못하여 증기가 응축수에 혼입되는 양이 많으면 연결관(26)에 설치한 밸브(27')는 개방하고 제 1 온수 출탕관(21)에 설치한 밸브(27)를 폐쇄한 후 온수가열 열교환기(20)에서 가열된 온수를 온수 가열조(24)를 경유하여서 증기트랩(5)에서 분리되지 못한 증기가 가열관(23)을 경유할 때 온수 가열조(24) 내의 온수와 열교환시킴으로써 배출관(4)으로 배출되는 증기 및 냉각수는 응축되어 응축수 탱크(6)에 유입되고, 가열관(23)에서 증기의 응축이 완전히 되지 못하였을 경우에는 상기한 증기의 혼입량이 작을 때에 같이 응축수 탱크(6)에서 재응축되기 때문에 증기는 배기관(11)으로 배출되지 않게 되며, 온수 가열조(24)에서 재가열된 온수는 제 2 온수 출탕관(25)을 통하여 온수 저장탱크(22)에 저장하였다가 필요한 용도에 사용하는 것이다.When the vapor and condensate are separated from the steam trap 5 and the separation is not good, and the amount of steam is mixed into the condensate, the valve 27 'installed in the connecting pipe 26 is opened and the first hot water tapping pipe is opened. After closing the valve (27) installed in the (21) and the hot water heated in the hot water heating heat exchanger (20) via the hot water heating tank 24, the steam not separated from the steam trap (5) is heated tube 23 By heat exchange with the hot water in the hot water heating tank 24 when passing through), the steam and cooling water discharged to the discharge pipe (4) is condensed and introduced into the condensate tank (6), the steam is not completely condensed in the heating pipe (23) If not, the steam is not discharged to the exhaust pipe 11 because it is condensed in the condensate tank 6 as when the mixing amount of the steam is small, the hot water reheated in the hot water heating tank 24 is discharged to the second hot water. Storage in the hot water storage tank 22 through the hot water pipe (25) It is used for necessary use.

또한 증기트랩(5)에서 증기가 분리될 때 응축수에 증기의 혼입량이 작을 경우에도 상기 증기의 혼입량이 많을 경우와 같이 밸브(27')를 개방하면 증기는 2회에 걸쳐 응축되기 때문에 증기의 응축이 양호하게 되며, 상기와 같이 증기의 혼입량이 적거나 많을 경우에도 밸브(27)(27')를 모두 개방하여 온수 가열관(20)에서 가열된 온수의 일부는 직접 온수 저장탱크(22)에 저장하고 일부는 온수 가열조(24)를 경유 재가열하여 온수 저장탱크(22)에 저장할 수도 있는 것이다.In addition, even when the amount of vapor in the condensate is small when the steam is separated from the steam trap 5, when the valve 27 'is opened as in the case where the amount of vapor is mixed, the steam is condensed twice. In this case, even when the mixing amount of steam is small or large as described above, all of the hot water heated in the hot water heating tube 20 by opening all the valves 27 and 27 'is directly connected to the hot water storage tank 22. Some of them may be stored in the hot water storage tank 22 by reheating the hot water heating tank 24.

상기와 같이 증기트랩(5)에서 분리되지 못한 증기를 온수가열에 활용함으로써 열손실을 줄일 수 있고, 응축수 탱크(6)와 온수 가열조(24)에서 온수를 부수적으로 생성할 수 있는 것이다.By using the steam not separated from the steam trap 5 in the hot water as described above can reduce the heat loss, it is possible to additionally generate hot water in the condensate tank (6) and hot water heating tank (24).

이상과 같이 본 발명은 증기 보일러의 환수장치의 응축수 탱크에 온수 가열열교환기를 내장하고, 증기트랩의 출구측 배출관에 가열관을 형성함과 동시에 그 주위에 온수 가열조를 형성하여 냉수 또는 가열된 온수에 의하여 증기트랩에서 분리되지 못한 증기를 응축시킴으로써 열손실을 방지하고, 또한 응축수 탱크 및 온수 가열조에서 온수를 부수적으로 생설할 수 있음으로 에너지 절감에 기여할 수 있는 것이다.As described above, the present invention incorporates a hot water heating heat exchanger in a condensate tank of a return device of a steam boiler, forms a heating tube in an outlet pipe of a steam trap, and forms a hot water heating tank around the cold water or heated hot water. By condensing the steam not separated from the steam trap by the heat loss can be prevented, and condensed water tank and hot water in the condensed water can be produced incidentally to contribute to energy savings.
