The structure of the Cryogenic Storage Tank
The storage tank and supercharger consist of integrated components that allow the supply of liquid or gas without the need for external power, ensuring the purity of the discharged liquid or gas. Additionally, they are equipped with a pressure conditioning installation, enabling users to adjust the conditioning valve (T) to achieve the desired pressure for liquid discharge. This ensures stable pressure and convenient operation. The storage tank also features a liquid filling joint for tank cars, facilitating the transfer of liquid to vaporizers and tank cars.
The tank is equipped with top and bottom liquid inlet pipelines, which can realize pressure difference and low temperature liquid pump unloading and filling;
The liquid outlet of the storage tank can supply gas directly or enter the cryogenic pump for external gas supply;
The storage tank is equipped with gas-phase pipelines, which can realize gas discharge, safe release, pressurization and gas return after pumping;
The storage tank is equipped with an overflow pipeline to avoid overfilling when unloading and filling;
The storage tank is equipped with double safety valves (or rupture discs) to discharge when overpressure to protect the safety of the inner container;
The storage tank is equipped with a pressure gauge to display the internal pressure in real time, which should be checked regularly according to regulations;
The storage tank is equipped with a liquid level meter to display the internal medium stock, which is used for reference and not for measurement;
The tank is equipped with vacuumizing and measuring vacuum pipelines to ensure the insulation performance of interlayer;
The tank is equipped with shell explosion-proof device to discharge gas in case of leakage of inner container to avoid serious damage and danger;
The interlayer of storage tank is high vacuum multi-layer winding insulation, which has small volume, good insulation effect.
Note: the parameters of safety valve shall not be changed at will and shall be calibrated regularly, otherwise it will cause safety accidents.
