Working principle of liquid oxygen tank
Liquid oxygen storage tank is a kind of equipment specially used for storing liquid oxygen. Liquid oxygen (LOX) has a boiling point of -183℃ at normal pressure and needs to be stored at extremely low temperature. Therefore, the design of liquid oxygen storage tank must be able to withstand extremely low temperature and prevent heat from entering.
Liquid oxygen storage tank usually consists of inner tank and outer tank. The inner tank is used to directly store liquid oxygen, while the outer tank provides thermal insulation protection. Usually, vacuum or insulation material is filled between the two layers of tanks to minimize heat conduction. The working principle of liquid oxygen storage tank mainly includes the following points:
Insulation design: multi-layer insulation technology and vacuum interlayer are used to reduce the heat entering the inner tank, so as to maintain the low temperature state of liquid oxygen.
Pressure regulation: Liquid oxygen may partially vaporize and generate pressure due to the absorption of external heat during storage and transportation. The storage tank is equipped with a safety valve and a pressure regulation system to prevent excessive pressure.
Cryogenic material: The inner tank material is usually made of stainless steel or aluminum alloy, which has good mechanical properties and corrosion resistance at low temperature.
