상기의 목적을 달성하기 위한 본 발명의 공기압축기의 흡입공기 냉각방법은, 다단의 필터(2)(3)가 설치된 필터하우스(1)에 인입되는 대기중의 원료공기를 소음기(5)가 설치된 파이프라인(4)을 통해서 공기압축기(6)에 공급함에 있어서, 상기 필터하우스(1)의 외측벽을 단열재(14)로 덮어 주위의 온도로부터 단열시키는 공정과, 상기 필터하우스(1)의 입구로부터 각각의 필터(2)(3) 사이에 저온의 냉매와의 사이에서 열교환이 일어나도록 열교환기(11)(12)(13)를 각각 설치하여 공기압축기(6)로 흡입되는 원료공기를 순차적으로 냉각하는 냉각공정을 포함하여 구성됨을 특징으로 한다.Inlet air cooling method of the air compressor of the present invention for achieving the above object, the silencer (5) is installed in the air raw air to be introduced into the filter house (1) in which the multi-stage filter (2) (3) is installed. In supplying to the air compressor 6 through the pipeline 4, the outer wall of the filter house 1 is covered with a heat insulating material 14 to insulate from the ambient temperature, and from the inlet of the filter house 1; Heat exchangers 11, 12 and 13 are respectively installed to exchange heat with the low temperature refrigerant between the respective filters 2 and 3 so as to sequentially feed raw air sucked into the air compressor 6. It characterized in that it comprises a cooling step of cooling.

이와 같이 본 발명에서는 필터하우스(1)로 인입되는 대기중의 공기를 외부의 고온으로부터 단열시키고, 순차적으로 설치된 열교환기를 통과함에 의해 냉각시켜 공기압축기에 공급함으로써, 공기압축기 및 후공정에서의 소요 에너지를 절감할 수 있게 된다.As described above, in the present invention, the air in the air introduced into the filter house 1 is insulated from the outside high temperature, cooled by passing through a heat exchanger installed in sequence, and supplied to the air compressor, thereby requiring energy in the air compressor and the subsequent process. Can be reduced.

이하에서는 첨부도면을 참조하여 본 발명의 일실시예에 대하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

도 2는 본 발명의 장치가 설치된 원료공기 흡입공정을 개략적으로 나타낸 것으로서, 필터하우스(1) 내에 두개의 필터, 즉 제1 및 제2 필터(2)(3)가 설치된 경우를 예를 들어 나타내고 있다.FIG. 2 schematically shows a raw air suction process in which the apparatus of the present invention is installed, and shows, for example, a case where two filters, namely, first and second filters 2 and 3 are installed in the filter house 1. have.

우선 상기 필터하우스(1)에 인입되어 통과하는 원료공기를 외부의 고온으로부터 단열시키기 위하여 태양열에 노출되어 있는 콘크리트로 제작된 상기 필터하우스(1)의 외측벽에 단열재(14)를 덮어 씌워서 태양열로부터의 열방사를 차단시킨다.First, the heat insulating material 14 is covered by covering the outer wall of the filter house 1 made of concrete exposed to solar heat to insulate the raw air passing through the filter house 1 from outside high temperature. Shut off heat radiation.

상기 필터하우스(1)로 인입되는 원료공기를 입구와 제1 필터(2) 사이에 설치된 예비냉각용의 제1 열교환기(11)를 통과시키면서 예비 냉각시킨다.The raw air introduced into the filter house 1 is precooled while passing through the first heat exchanger 11 for precooling provided between the inlet and the first filter 2.

상기 제1 열교환기(11)는 예를 들어 외부로 부터 냉매가 흐르고 있는 구조를 갖는 것을 사용할 수 있다.For example, the first heat exchanger 11 may have a structure in which a refrigerant flows from the outside.

이때 인입되는 공기의 온도와 제1 필터(2)로 향하는 공기의 온도가 감지되어 운전실의 화면상에 송신되고, 운전자의 지시 또는 자동으로 다음 공정으로 연결되도록 한다.At this time, the temperature of the incoming air and the temperature of the air directed to the first filter 2 is sensed and transmitted on the screen of the cab, so as to be connected to the next process automatically or instructed by the driver.

상기 필터하우스(1)에 흡입된 원료공기는 상기 예비 냉각공정에 이어서 제1 필터(2)와 제2 필터(3)의 사이에 설치된 제2 열교환기(12)를 통과하면서 위에서와 마찬가지로 냉매와의 열교환에 의해 냉각된다.The raw material air sucked into the filter house 1 passes through the second heat exchanger 12 provided between the first filter 2 and the second filter 3 following the preliminary cooling process, and the refrigerant and Is cooled by heat exchange.

이어서, 상기 제2 필터(3)의 외측에 설치된 제3 열교환기(13)를 통과하면서 다시 한번 냉각되고, 이때도 공기의 온도가 감지되어 운전실로 송신되고, 운전자의 지시 또는 자동으로 흡입되는 원료공기의 온도가 조절될 수 있도록 한다.Subsequently, the raw material is cooled once again while passing through the third heat exchanger 13 installed outside the second filter 3, and at this time, the temperature of the air is sensed and transmitted to the cab, and is instructed by the driver or automatically sucked. Allow air temperature to be controlled.

한편, 상기 각각의 열교환기(11)(12)(13)에 사용되는 냉매로는 상기 공기압축기(6)를 통과한 후에 분리 생산되는 저온의 액체 질소(질소 가스) 등을 사용할 수 있고, 이 경우에는 사용 예정인 액체 질소(질소 가스)를 그 경로만 변경하여 사용함으써 별도의 냉매를 필요로 하지 않게 되어 한층 바람직하다.On the other hand, as the refrigerant used in each of the heat exchangers 11, 12, 13, low-temperature liquid nitrogen (nitrogen gas), etc., which are separated and produced after passing through the air compressor 6, may be used. In this case, the liquid nitrogen (nitrogen gas), which is to be used, is changed only in its path so that a separate refrigerant is not required.

이와 같이 구성되는 본 발명을 광양제철소의 산소생산설비에 설치된 공기압축기를 대상으로 이론적으로 계산한 결과 에너지 절감 효과가 우수함을 확인할 수 있었다.As a result of theoretical calculation of the air compressor installed in the oxygen production facility of Gwangyang Works, it was confirmed that the energy saving effect is excellent.

즉, 공기압축기로 흡입되는 원료공기의 온도를 1℃ 낮춤에 의해 57㎾의 전기가 절감되고, 결국 1대의 공기압축기 당 연간 2천여만원의 에너지 비용을 절감할 수 있다.In other words, by lowering the temperature of the raw air sucked into the air compressor by 1 ° C, the electricity of 57 kW is saved, and thus, the energy cost of 20 million won per year per air compressor can be saved.

이상에서 상세히 설명한 바와 같이, 본 발명의 공기압축기의 흡입공기 냉각방법을 사용하면, 흡입되는 원료공기의 온도를 낮춤에 의해 공기압축기 및 후공정에서 소요되는 에너지를 절감할 수 있을 뿐만 아니라, 후공정에서의 냉각설비의 부담을 줄일 수 있는 효과가 있다.As described in detail above, by using the intake air cooling method of the air compressor of the present invention, by lowering the temperature of the raw material air to be sucked, it is possible to reduce the energy required in the air compressor and the post process, as well as the post process This can reduce the burden on the cooling system.
