Description

Technical Field

[0001] This utility model relates to the field of fixed storage tank technology, and in particular to a fixed storage tank for holding cryogenic liquids. Background Technology

[0002] Stationary storage tanks for cryogenic liquids are specialized devices installed at cryogenic liquid production sites, usage points, or supply stations. They are not mobile and typically have a double-cylinder structure. The inner cylinder and its piping are made of austenitic stainless steel to hold the cryogenic liquid, while the outer shell is made of carbon steel. The interlayer is filled with expanded perlite and contains specially treated adsorbents. A high vacuum is created to achieve excellent insulation and reduce heat transfer. Their capacity is generally below 200 m³, and they operate at relatively high pressures.

[0003] However, some cryogenic liquids in these devices are extremely heavy, and even slight vibrations or operational impacts can cause them to tip over. A tipping incident can easily cause cracks in the tank welds, directly leading to cryogenic liquid leakage. Furthermore, cryogenic storage tanks require regular inspections of internal wall corrosion and insulation integrity; failure to remove the tank cover in a timely manner prevents these critical inspections from being carried out, accelerating equipment aging. Utility Model Content

[0004] The purpose of this invention is to ensure the overall stability of the storage tank and prevent it from being pushed by internal pressure. It provides a fixed storage tank for holding cryogenic liquids, which solves the problem of stress concentration caused by shaking during operation, which can damage the tank body or insulation layer in the long run, reduce equipment service life, and increase unplanned maintenance costs.
