Description

Technical Field

[0001] The utility model relates to the technical field of liquid oxygen vaporization, in particular to a liquid oxygen vaporization backup system. Background Art

[0002] A liquid oxygen boil-off backup system is a device used to convert liquid oxygen into gaseous oxygen. It is commonly used in aerospace, medical facilities, and industrial applications. This system can provide oxygen when needed and ensure that the oxygen can be put into use or circulation in the appropriate form. Usually, liquid oxygen is vaporized into a gaseous state by heating for easy transportation and use.

[0003] When liquid oxygen becomes oxygen inside the tank, since the temperature of liquid oxygen is much lower than room temperature, the moisture in the air will condense on the outer wall of the tank to form water droplets. This is because the temperature eutectic point of liquid oxygen is very low. After contacting with the surrounding environment, the water vapor in the surrounding air condenses into liquid water. The water attached to the outer wall of the oxygen tank may cause corrosion, especially if the oxygen tank is made of metal, which may damage the appearance of the oxygen tank and may cause leakage or other safety hazards. The oxygen tank has a certain surface area, which is more troublesome for staff to clean. Utility Model Content
