Working principle of liquid oxygen tank

The purpose of safe distance from liquid oxygen storage containers is to ensure safety.

Material selection for liquid oxygen tanks is critical because they must be able to withstand extreme cryogenic conditions, high pressures, and the highly oxidizing properties of liquid oxygen.

Liquid oxygen tanks have a wide range of applications, covering a number of important areas, each of which makes full use of the characteristics and advantages of liquid oxygen.

The testing of liquid oxygen tanks covers many aspects, including pressure testing, vacuum maintenance testing, chemical and physical testing, welding quality inspection, leak testing, and emergency response drills.

Vertical/horizontal cryogenic liquid oxygen storage tank is a kind of equipment for storing and transporting liquid oxygen, which is characterized by high efficiency, safety and energy saving.

Storage of liquid oxygen must be insulated, so the liquid oxygen tank has an inner tank, an insulation layer (or vacuum layer), and an outer shell.

Whether during transportation, operation or storage, liquid oxygen tanks must be kept upright and effectively isolated.

The protective equipment and appearance of the liquid oxygen storage tank should be in good condition, and purging and cleaning have been completed

The stainless steel inner tank is suitable for contact with low-temperature media, and the plate thickness can withstand 8 to 16 kilograms of pressure, which is enough to ensure the pressure-bearing safety of the cryogenic liquid oxygen tanks.

The installation site must have good ventilation conditions or ventilation and ventilation devices, and can safely discharge liquids and gases.

Liquid oxygen storage tanks are mainly used for cryogenic liquid storage of oxygen.

Before using liquid oxygen storage tanks, a small amount of liquid nitrogen should be put in to pre-cool it.

The structure of liquid oxygen storage tanks is carefully designed to have sufficient strength and toughness to prevent rupture or leakage under extreme conditions.

According to the size, material and design requirements of the tank, select the appropriate welding method, such as tungsten inert gas welding (TIG), metal arc welding (MIG) or electron beam welding.

The tank needs to be precooled before filling to avoid overheating when the liquid oxygen comes into contact with the inner wall of the tank.

Liquid oxygen tanks convert oxygen into liquid by cooling it below its liquefaction point (about -183°C). A vacuum insulation layer is provided inside the tank to reduce the evaporation loss of liquid oxygen. Liquid oxygen is converted into gaseous oxygen for use when needed through an evaporator.

The safety of liquid oxygen storage tanks is key to ensuring the safety of liquid oxygen storage and handling processes, because liquid oxygen (LOX) has extremely low temperatures and strong oxidizing properties when in liquid form

In the medical field, the application of liquid oxygen tanks is crucial. They not only provide an efficient way to store oxygen, but also greatly promote the development of various medical activities.

The maintenance of liquid oxygen tanks includes the maintenance of the outer shell and inner cylinder, the maintenance of the insulation system, the calibration of safety accessories, and the maintenance of the vacuum degree.

Evaporation losses in liquid oxygen storage tanks may lead to oxygen waste and environmental impact. Reduce the environmental impact of evaporation losses by optimizing design and operation.

The inner liner of liquid oxygen storage tank is made of 16MnDR and the outer liner of liquid oxygen storage tank is made of Q245R or Q345R.The liquid oxygen storage reservoir selects “combination, safety system valve” using two groups of safety valves to work together, in the time calibration of the safety valve can be closed on one side, the other side is still working, to ensure the safe operation of the liquid oxygen storage reservoir.
