Description

공기통의 압축공기 충진장치{Compressed air charger for oxygen bomb}Compressed air charger for oxygen bomb

본 발명은 공기통(이하에서는 스킨스쿠버 혹은 소방관등이 사용하는 공기공급용 산소통을 총칭함)의 압축공기 충진장치에 관한 것으로 상세하게는 압축공기 충진장치에 관한 것이다.The present invention relates to a compressed air filling apparatus of an air cylinder (hereinafter, collectively referred to as an oxygen cylinder for supplying air used by skin scuba or firefighters), and more particularly, to a compressed air filling apparatus.

종래에 사용되어온 압축공기 충진방식의 예를 살펴본다.Look at an example of a conventional compressed air filling method.

우선 선진국의 경우에는, 산소의 비율을 맞추기 위해서, 고압 산소통의 산소를 원하는 양만큼 공기통에 채운 후에 나머지는 다단식 초고압 공기압축기를 통해서 공기를 채우는 방법으로, 예를들면, 27% 6.8리터(liter)공기통을 만든다고 하면100% 산소를 26bar까지 충진한 후에 다단식 공기압축기를 사용하여 300bar까지 압력을 채우는 방식이다. 고압에서 높은 산소순도와 압축열에 의한 폭발의 위험성을 피하기 위해서 선택되어진 방법이지만, 고압 산소통에 산소를 항상 채워 넣어야 한다는 단점이 있다.First, in developed countries, in order to match the proportion of oxygen, the oxygen in the high pressure oxygen tank is filled into the reservoir by the desired amount, and the rest is filled with air through a multistage ultrahigh pressure air compressor, for example, 27% 6.8 liters. In case of making a reservoir, it fills up to 26 bar with 100% oxygen and fills the pressure up to 300 bar using a multistage air compressor. The method has been selected to avoid the explosion risk due to high oxygen purity and heat of compression at high pressure, but has the disadvantage of always filling oxygen into the high pressure oxygen cylinder.

다른 방법은 공기를 고압통에 충진하였다가 멤브레인(membrane)을 통과시키면서 40% 정도의 산소를 만들어내어, 공기압축기를 통해서 충진하는 것이다. 이 방법 또한 고압통에 항상 공기를 충진시켜야 하는 단점이 있을 뿐 아니라, 고온에서 폭발의 위험성이 있다.Another method is to charge air through a high pressure vessel and produce about 40% of oxygen as it passes through a membrane, filling it through an air compressor. This method also has the disadvantage of always filling the high pressure vessel with air, as well as the risk of explosion at high temperatures.

국내에서는 최근에 산소농축장치가 도입사용되고 있다. 즉, 다단식 초고압 공기압축기의 흡기구에 별도의 산소농축장치에서 농축된 산소를 흘려 넣어주는 방식으로 흡입 공기의 순도를 높여서 공기통을 충진하는 방법으로, 예를들면, 23%의 산소를 포함하는 공기를 충진한다면 산소농축장치에서 발생된 산소와 다단식 초고압 공기압축기의 흡입구에서 흡입하는 공기를 섞어 산소순도를 23%로 맞춘 후에 충진하는 방식이다. 이 방식 또한 고온, 고압에서 산소순도가 높은 공기를 충진하기 때문에 폭발의 위험성이 있다. 게다가 기존의 산소농축장치를 별도로 구비하여 사용하므로 2개의 기계를 작동시켜야 하는 번거로움이 있다. 이 장치의 또 다른 단점은 산소의 양이 정해져 있고, 충진시간이 정해져 있으므로 항시 정해진 산소순도로만 충진이 가능하고 산소순도의 제어가 불가능하였다.Recently, an oxygen concentrating device has been introduced and used in Korea. That is, a method of filling a reservoir by increasing the purity of intake air by pouring concentrated oxygen from a separate oxygen concentrator into an intake port of a multistage ultra high pressure air compressor, for example, air containing 23% oxygen If it is filled, the oxygen generated from the oxygen concentrator is mixed with the air sucked from the inlet of the multistage ultra high pressure air compressor, and the oxygen purity is adjusted to 23%. This method also has a high risk of explosion because it fills air with high oxygen purity at high temperatures and pressures. In addition, since the existing oxygen concentrating device is provided separately, it is troublesome to operate two machines. Another disadvantage of this device is that the amount of oxygen is fixed and the filling time is fixed, so it is always possible to fill only with the predetermined oxygen purity and control of the oxygen purity is impossible.

일반적으로 공기통에의 산소순도 구분은 대부분 23%, 27%로 나뉜다. 그러나 종래와 같이 상당한 순도의 농축산소를 흡입초기부터 다단식으로 압력을 증가하면서 충진하게 되면 어느 단계에선가는 순도조정과 폭발의 위험을 피하기 위해서 농축산소의 공급을 정지하여야 한다.In general, the oxygen purity in the air tank is divided into 23% and 27%. However, when the concentrated oxygen of a considerable purity is filled with increasing pressure from the initial stage of inhalation, the supply of concentrated oxygen must be stopped at some stage to avoid the risk of purity adjustment and explosion.

따라서 공기통등에 소정의 순도를 갖는 압축공기의 주입시에 산소순도를 제어함과 동시에 고압압축에 따른 위험성을 해결할 수 있는 압축공기 충진방식이 필요로 되는 것이다.Therefore, the compressed air filling method that can control the oxygen purity at the time of the injection of compressed air having a predetermined purity in the air chamber and can solve the risks associated with high pressure compression.

본 발명은 산소농축장치를 구비하되 공기압축기를 별도로 갖추지 않고, 다단식 초고압 공기압축기의 1차압축기를 산소농축장치와 연결하여 산소를 발생시키도록 하면서 농축된 산소를 다시 다단식 공기압축기의 2차압축기의 흡입구에 넣어 3, 4차압축기를 거쳐 공기통에 충진하게 하는 압축공기 충진장치를 제공하려는 데에 발명의 목적이 있다.The present invention is provided with an oxygen concentrator, but without having an air compressor separately, by connecting the primary compressor of the multistage ultrahigh pressure air compressor with the oxygen concentrator to generate oxygen, and the concentrated oxygen again in the secondary compressor of the multistage air compressor. An object of the present invention is to provide a compressed air filling device to be filled in the intake port through the third and fourth compressors.

본 발명은 이와같은 점을 감안하여 별도의 산소농축장치를 구비하지 않고 다단식 공기압축기의 사이에 산소농축모듈을 적절히 결합하여 산소순도의 제어와 압력을 적절히 조절할 수 있는 압축공기 충진방식을 제공하는 데에 그 목적이 있다.In view of the above, the present invention provides a compressed air filling method capable of appropriately controlling oxygen purity and adjusting pressure by appropriately combining an oxygen concentrating module between a multistage air compressor without providing a separate oxygen concentrating device. Has its purpose.

상기 목적을 달성하기 위한 본 발명 압축공기 충진방식은 다단식 초고압공기압축기의 1단과 보조압축기를 사용하여 산소농축모듈에 압축공기를 공급하고, 별도 생성된 압축공기의 일부와 농축된 산소를 혼합하여 2단 입구에 넣어주는 압축공기 충진방식을 제공하는 데에도 그 목적이 있다.In order to achieve the above object, the present invention provides a compressed air filling method by supplying compressed air to an oxygen concentrating module by using a first stage and an auxiliary compressor of a multistage ultra high pressure air compressor, and mixing a part of the separately generated compressed air with concentrated oxygen. The purpose is to provide a compressed air filling method that is put in the inlet.

본 발명 충진방식은 다단계 초고압공기압축에 있어 적어도 하나 이상의 산소농축모듈에 공기를 공급하면서 공기통을 충진하는 데도 공기를 공급하도록 하고,산소를 농축하지 않으면서도 공기통을 충진할 수 있는 공기충진방식을 제공하는 데에도 그 목적이 있다.The filling method of the present invention provides an air filling method to fill the air reservoir without concentrating oxygen while supplying air to the air reservoir while supplying air to at least one or more oxygen concentration modules in the multi-stage ultra high pressure air compression. The purpose is to do that.

본 발명 다단식 초고압공기압축장치는 산소농축모듈을 순도제어가 가능해진다.According to the present invention, the multistage ultra high pressure air compression device is capable of controlling purity of the oxygen concentration module.

Here, the compressed air compressed at a predetermined pressure (about 13-15kgf / ㎠) is about 3rd (when connecting a plurality of low compressors depending on pressure equipment conditions, a 4th compression process may be required). After compression to a high pressure of 30-50kgf / ㎠ and filled in the air reservoir 80 through the air purification filter (60).
