What are the importance of 30 cubic cryogenic storage tanks?

30 cubic cryogenic storage tanks, often called cryogenic tanks or liquid storage tanks. Its structure can be divided into two layers. The first layer is the inner layer. It is made of austenitic stainless steel. The outer layer is made of interlayer filled with some heat-resistant pearlescent sand. Vacuumed.

Cryogenic storage tanks are used for cryogenic liquid storage of gases such as liquid oxygen or liquid nitrogen and carbon dioxide. One cubic meter of liquid can usually replace one hundred and thirty gas cylinders. The cryogenic storage tank can replace the round-trip transportation of gas cylinders, which saves manpower and material resources to a great extent.

When the storage tank is in operation, there are potential dangers such as leakage, overpressure, and explosion. If the hidden dangers before handling these incidents are not found in time, serious accidents will result. Therefore, it is very important to formulate a perfect inspection system and implement it carefully to ensure the safe operation of the storage tank. The daily inspection of the tank mainly includes the following:
1. Are the valves and pipelines leaking, and is the casing frosting or sweating?
2. Check whether the valve is in normal condition.
3. Is the external surface (level gauge, pressure gauge) operation normal? Is the DCS display parameter consistent with the on-site meter? 4. Is the pressure in the storage tank normal? When the pressure is close to or equal to the high pressure, the vent valve needs to be opened to release the pressure.
5. Is the liquid overflow rate exceeding 95%?
6. Regarding the atmospheric pressure powder insulation tank, is the sealing gas normal?
7. It is strictly prohibited to place flammable, dangerous goods and other sundries near the liquid oxygen storage tank.
8.Fireworks are strictly prohibited near the liquid oxygen storage tank.

When the pressure in the tank reaches the drain request, the liquid can be drained. In order to ensure the purity of the storage medium and reduce the loss of medium liquid during the next filling, the storage tank should generally not be completely emptied. The drainage system of the storage tank can ensure that 10 liters of liquid remain in the tank.
