Support structure of inner tank and outer shell of cryogenic tank
Date: May 06, 2020
The cryogenic storage tank is a vertical or horizontal double-layer vacuum insulated storage tank for storing liquid oxygen, nitrogen, argon, carbon dioxide and other media. Its main function is to fill and store cryogenic liquid. Regarding the requirements for the safe use of cryogenic storage tanks, comprehensive consideration shall be given to gas hazard characteristics, low-temperature protection effects, surrounding environmental conditions, pressure vessel characteristics, etc., and corresponding technical management measures shall be taken to ensure safe operation.
Low-temperature storage tanks can be divided into atmospheric cryogenic storage tanks by volume. The equipment is a flat-bottomed arch cover and a vertical double-wall structure. The interlayer is filled with pearlite sand for thermal insulation and nitrogen protection. Set internal and external trough breathing valves and emergency relief devices to ensure the safe operation of the equipment.
The body of the cryogenic storage tank is composed of two layers inside and outside, with a heat insulation structure and a cold insulation layer between the two layers. The inner tank is used for storage, while the outer shell is used for protection and cold preservation. In order to reduce the transfer of external heat into the tank, the designed internal and external tanks are separated and independent. The tank item is a self-supporting vault, and the inner tank item must have sufficient strength and stability to withstand the external pressure caused by the cold insulation material, etc. and the internal pressure generated by the internal gas.
The cryogenic tank is composed of an inner tank and an outer shell, but due to the use of the storage tank, there are great requirements on the support structure.
The support structure between the liner and the outer shell is supported by the upper stainless steel strap and the lower stainless steel tube. In the normal position of the equipment, the gravity load of the liner and its storage medium is transmitted to the casing through 3 stainless steel pipes, and then to the casing legs and the foundation of the equipment to avoid additional eccentric moment load The need for free contraction of the liner under low temperature working conditions.
