본 고안은 공기 압축기의 배관 구조에 관한 것으로, 특히 공기 압축기에서 고온의 압축 공기의 냉각열을 이용할 수 있는 배관 구조에 관한 것이다.The present invention relates to a pipe structure of an air compressor, and more particularly to a pipe structure that can use the cooling heat of the high-temperature compressed air in the air compressor.

일반적으로 공기 압축기는 대기의 공기를 흡입하여 고압으로 압축하여 압축 공기를 각종 산업기계등에 공급하는 설비로서, 통상 2단계의 압축 과정을 거치게 되는데, 이때 압축 공기가 압축기로부터 나올 때 상당한 고압.고안의 상태가 된다.In general, an air compressor is a facility that sucks atmospheric air, compresses it to high pressure, and supplies compressed air to various industrial machines. The air compressor generally undergoes two stages of compression, and when compressed air comes out of the compressor, It becomes a state.

한편, 압축 과정에 오일이나 냉각수를 압축기 주변에 흘러주어 압축열을 부분적으로 간접냉각시키게 된다.Meanwhile, during the compression process, oil or cooling water flows around the compressor to partially indirectly cool the heat of compression.

이러한 압축 공기는 보통 그대로 산업 형장에 보낼 수 없을 정도로 고온상태가 되므로 냉각장치를 거쳐 대기온도에 가까운 온도로 냉각시킨 상태로 공급된다.Since such compressed air is so hot that it can not be sent to the industrial mold as it is normally, it is supplied to the state cooled to a temperature close to the atmospheric temperature through a cooling device.

제 2 도는 이러한 냉각장치가 포함된 압축기에 대한 흐름도로서, 대기의 공기가 흡입구(21)를 통해 흡입된 다음, 필터(22)를 거쳐 1차 압축기(23)에서 압축된 후, 중간 냉각기(24)에서 냉각되고, 다시 2차 압축기(25)에서 압축된 후 냉각기(26)에서 냉각되어 대기의 온도상태에서 공기토출구(27)를 나가게 되어 있다.2 is a flow chart of a compressor including such a cooling device, in which atmospheric air is sucked in through the inlet port 21, and then compressed in the primary compressor 23 through the filter 22, and then the intermediate cooler 24. ) Is cooled by the secondary compressor 25, and then cooled by the cooler 26 to exit the air outlet 27 at the atmospheric temperature.

그리고 상기 냉각기(24,25)에는 냉각수입구(28)에서 공급된 냉각수가 통과하면서 압축기(23,25)를 거쳐나온 고온의 압축공기를 냉각시킨 후 냉각수 출구(29)로 나가도록 되어 있다.The coolers 24 and 25 pass through the cooling water supplied from the cooling water inlet 28 to cool the high temperature compressed air passing through the compressors 23 and 25 and then exit the cooling water outlet 29.

상기한 바와같은 종래의 냉각 방식은, 고온의 압축 공기로부터 열을 흡수한 냉각수가 냉각탑으로 이동되어 대기로 방열시키게 되어 있으므로, 결국 전체적으로 볼 때 상당한 열에너지의 손실을 초래하게 되고, 에너지 이용 효율도 낮게는 된다는 문제점이 있었다.In the conventional cooling method as described above, since the cooling water absorbing heat from the high-temperature compressed air is moved to the cooling tower to radiate heat into the atmosphere, it causes a significant loss of thermal energy as a whole and low energy utilization efficiency. There was a problem.

이에 본 고안을 상기한 바와 같은 문제점을 해소하기 위해 안출된 것으로, 공기압축기에서 압축된 고온. 고압의 압축공기를 냉각시키면서 상대적으로 고온으로 가열된 냉각수의 폐열을 난방이나 다른 유용한 용도로 이용할 수 있는 배관 구조를 제공하는데 그 목적이 있다.In order to solve the problems as described above the present invention is a high temperature compressed in the air compressor. It is an object of the present invention to provide a piping structure in which waste heat of cooling water heated to a relatively high temperature while cooling high pressure compressed air can be used for heating or other useful purposes.

상기한 바의 목적을 달성하기 위한 본 고안은, 압축기의 후 냉각기 입구측 공기관과 출구측 공기관 사이에 상기 후 냉각기를 통과하지 않는 분기관이 병렬로 연결설치되고, 이 분기관은 열교환장치를 통과하도록 되어 후 냉각기를 통과하지 않는 고온의 압축공기가 상기 열교환장치를 통과하면서 냉각되도록 되어 있으며, 상기 분기관의 입구측과 상기 후 냉각기의 입구측 공기관에는 각각 유로를 개폐하는 밸브가 설치되어 있는 한편, 상기 후 냉각기의 출구측 분기관의 출구측에는 체크밸브가 설치된 구조로 되어 있다.The present invention for achieving the above object is, between the after-cooler inlet air pipe and the outlet-side air pipe of the compressor, the branch pipe which does not pass through the after cooler is installed in parallel, the branch pipe passes through the heat exchange device The compressed air of high temperature, which does not pass through the after cooler, is cooled while passing through the heat exchange device, and the inlet side of the branch pipe and the inlet side air pipe of the after cooler are provided with valves for opening and closing the flow path, respectively. The check valve is provided on the outlet side of the outlet side branch pipe of the after cooler.

상기한 배관구조에서 폐열을 이용하고자 하는 경우 공기 냉각기로 들어가는 밸브를 잠그고, 폐열을 이용하려는 설비, 예컨대 난방장치의 배관을 플랜지나 나사구조로 결합하고 공기토출구 즉 분기관에 폐열이용 설비에서 나오는 공기관을 연결시키면 된다. 한편 상기 구조는 냉각기에 적용하는 것도 마찬가지이다.If you want to use the waste heat in the above pipe structure, lock the valve to the air cooler, and the equipment to use the waste heat, for example, the pipe of the heating device by combining the flange or screw structure and the air outlet from the waste heat utilization equipment to the air outlet or branch pipe Just connect The same applies to the above structure applied to a cooler.

따라서 대기중으로 발산시켜 버리던 열에너지를 활용할 수 있으므로 공기 압축기의 효율이 증가하여 공기 압축기의 가동 비용을 감소시키는 효과를 얻을 수 있게 된다.Therefore, it is possible to utilize the heat energy that has been dissipated into the atmosphere, thereby increasing the efficiency of the air compressor can be obtained the effect of reducing the operating cost of the air compressor.

이하 본 고안을 첨부한 예시 도면을 참조하여 더욱 자세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

제 1 도는 본 고안에 따른 폐열 이용 배관 구조가 적용된 압축기의 흐름도로서 대기중의 공기가 공기 흡입구(1)를 거쳐 공기 필터(2)를 거쳐 1차 및 2 압축기(3,4) 및 중간 냉각기(5)와 후 냉각기(6)을 거쳐 토출구(7)로 토출되는 흐름은 종래과 같다.1 is a flow chart of a compressor to which the waste heat utilization piping structure according to the present invention is applied, and the air in the atmosphere passes through the air inlet 1 through the air filter 2 and the primary and secondary compressors 3 and 4 and the intermediate cooler ( 5) and the flow discharged to the discharge port 7 through the after cooler 6 is the same as in the prior art.

후 냉각기(6)의 입구측 공기관과 후 냉각기(6)의 출구특 공기관에는 각각 분기관의 입구측과 출구측이 각각 연결장치를 매개로 연결되고, 이 분기관은 열교환장치(10)을 통과하도록 되어 있다.The inlet side and the outlet side of the branch pipe are respectively connected to the inlet side air pipe of the after cooler 6 and the outlet special air pipe of the after cooler 6 through a connecting device, and the branch pipe passes through the heat exchange device 10. It is supposed to be.

그리고 상기 후 냉각기(6) 입구측 공기관과 상기 분기관의 입구측 선단에는 이들 공기관이나 분기관을 개폐하는 밸브(8a,8b)가 연결설치되어 어느 한쪽 유로를 차단함으로써 압축공기의 흐름방향을 전환할 수 있게 되어 있다.In addition, valves 8a and 8b for opening and closing the air pipes and the branch pipes are connected to the inlet air pipes of the post cooler 6 and the inlet-side ends of the branch pipes, thereby switching the flow direction of the compressed air by blocking one flow path. I can do it.

즉 상기 후 냉각기(6) 입구측 공기관에 구비된 밸브(8a)를 잠그고, 분기관의 입구측 밸브(8b)를 개방하면 고안의 압축공기는 열교환장치(10)쪽으로만 흐르면서 열교환하여 폐열을 활용하게 되고, 그 반대의 경우 후 냉각기(6)쪽으로만 흘러 냉각되게 되는 것이다.That is, after the valve 8a provided at the inlet side air pipe of the cooler 6 is closed, and the inlet side valve 8b of the branch pipe is opened, the compressed air of the present invention flows only toward the heat exchanger device 10 to utilize heat generated by heat exchange. On the contrary, the flow is cooled only after the cooler (6).

한편 후 냉각기(6)의 출구측 공기관에서도 토출구(7) 입구관측이 분기관의 선단에 역시 연결장치(9b)가 설치되며, 분기관과 후 냉각기 쪽의 관에 역류방지장치로서 체크밸브(11a,11b)가 설치되어 있다.On the other hand, in the air pipe at the outlet side of the cooler 6, the outlet 9 is also provided with a connecting device 9b at the tip of the branch pipe, and a check valve 11a as a backflow prevention device at the branch pipe and the pipe at the after cooler side. 11b) is provided.

상기와 같은 구조로된 폐열 이용을 위한 배관 구조에서, 폐열이용을 별도로 하지 않은 경우 후 냉각기(6)전의 밸브(8a)는 열고 분기된 관의 밸브(8b)는 닫으며, 후 냉각기(6)통 과후에는 역류방지 장치(11a,11b)로 인해 압축공기는 토출구(7)로 배출된다.In the piping structure for using waste heat having the above structure, the valve 8a before and after the cooler 6 is opened and the valve 8b of the branched pipe is closed and the cooler 6 is not used after the waste heat is not used separately. After passing, the compressed air is discharged to the discharge port 7 due to the backflow prevention devices 11a and 11b.

한편 폐열이용 수단으로 열교환장치(10)를 연결하는 경우 후 냉각기(6)입구측 공기관에 구비된 밸브(8a)는 잠그고, 분기관측 밸브(8b)는 열면 된다. 이러한 경우 후 냉각기는 이용되지 않게 되고 고온의 압축 공기는 별도 연결된 열교환장치(10)에서 열교환으로 열전달하여 냉각된 후, 압축기의 배관으로 돌아와 토출구(7)로 배출된다. 압축공기는 역류방지장치인 체크밸브(11a)로 인해 냉각기(6)쪽으로는 역류하지 않게 된다.On the other hand, when the heat exchanger 10 is connected by means of waste heat utilization, the valve 8a provided at the inlet side air pipe of the cooler 6 may be closed, and the branch side valve 8b may be opened. In this case, the cooler is not used and the hot compressed air is cooled by heat transfer by heat exchange in the heat exchanger 10 connected separately, and then returns to the piping of the compressor and is discharged to the discharge port 7. Compressed air does not flow back toward the cooler 6 due to the check valve 11a, which is a backflow prevention device.

따라서 상기와 같은 폐열 이용 장치를 결합할 수 있게 함으로써, 대기로 버려지던 열에너지를 난방이나 다른 유용한 용도로 쓸 수 있게 되어 에너지 효율이 증가되어 압축기의 가동 비용을 줄이는 효과를 가져오게 된다.Therefore, by allowing the waste heat utilization apparatus to be combined, it is possible to use the heat energy wasted into the atmosphere for heating or other useful uses to increase the energy efficiency has the effect of reducing the operating cost of the compressor.
