저압용 압축공기 탱크{A Compressed air tank andthe methode}Compressed air tank and the method for low pressure

본 발명은 주로 50㎏ｆ/㎠ 이하의 저압의 압축공기를 저장하는 저압용 압축공기탱크에 관한 것으로서, 더욱 상세하게는 공기를 압축하여 저장하는 탱크 중 이동식 탱크로써 내부에서 공기 중에 함유된 수분이 공기압축으로 인하여 액화됨에 따라 바닥면에 고임은 물론 탱크의 내부를 부식시켜 손상을 입힘으로써 안전사고를 발생시키는 것을 방지하여 안전하게 사용될 수 있는 저압용 압축공기 탱크 및 그 제조방법에 관한 것이다.
The present invention mainly relates to a low pressure compressed air tank for storing compressed air having a low pressure of 50 kg ｆ / ㎠ or less, and more particularly, the water contained in the air as a mobile tank of the tank for compressing and storing air The present invention relates to a low pressure compressed air tank and a method for manufacturing the same, which can be used safely by preventing the occurrence of a safety accident by corroding the inside of the tank and damaging the interior of the tank as it is liquefied due to air compression.

일반적으로 압축공기(壓縮空氣: Compressed air)는 압력을 가하여 부피를 축소시킨 공기로써, 일반 산업현장 및 의료에 널리 이용되고 있다.
In general, compressed air is compressed air which is reduced in volume by applying pressure, and is widely used in general industrial sites and medical treatments.

그리고 근자에는 산소에 대한 인체의 유익함이 알려져 건강을 위하여 고농도의 산소를 흡입하거나 물과 혼합하여 일종의 기능수인 산소수를 만들어 음용하기도 한다.And in the root of the body is known for the benefits of oxygen for health, inhaling a high concentration of oxygen or mixed with water to create a kind of functional water oxygen water to drink.

이와 같은 산소는 안전을 위하여 주로 50㎏ｆ/㎠ 이하의 저압으로 압축된 후 별도의 압축공기탱크에 보관하여 필요에 따라 사용을 하고 있다.Such oxygen is compressed at low pressure of 50 kgｆ / ㎠ or less for safety, and then stored in a separate compressed air tank and used as necessary.

즉 별도의 공간적 장소에 저장탱크를 설치하여 사용하고자 할 때 배출구를 통해 배출하여 사용을 하고 있다.
In other words, when a storage tank is installed and used in a separate space, it is discharged through an outlet.

그리고 압축탱크기 미설치된 공간에서 압축공기를 이용하고자 할 때에는 별도의 이동식 압축공기탱크를 이용하여 압축된 공기를 저장한 후 이동시켜 사용하고 있는 바, 이때의 공기압축탱크는 도 1에서 도시된 바와 같이 탱크의 길이방향을 수평상으로 하여 운반 및 저장을 하고 있다.And when using the compressed air in the space without the compression tank is used to store and move the compressed air using a separate mobile compressed air tank, the air compression tank is shown in Figure 1 Similarly, the tank is transported and stored in the longitudinal direction of the tank.

이것은 이동식 탱크의 공간활용에 따라 길방향을 수직상으로 형성할 경우 사용장소가 수직상 협소한 건물인 경우에는 사용이 어렵기 때문에 수직상 공간의 제한이 적은 수평탱크가 사용될 수밖에 없는 실정이다.
This is a situation where a horizontal tank with a small limit of vertical space is inevitably used when the road direction is vertically formed according to the utilization of the space of the mobile tank, because it is difficult to use when the place of use is a vertically narrow building.
