Additionally, the use of liquid carbon dioxide storage tanks must adhere to specific industry standards and regulations based on the particular industry and application scenario. For instance, when using liquid carbon dioxide storage tanks in the food and beverage industry, relevant food safety and hygiene standards must be followed. It is important to note that different regions may have varying standards and regulations applicable to the use of liquid carbon dioxide storage tanks. Therefore, operations and usage should be conducted in accordance with local laws and standards.

Low Temperature Carbon Dioxide Storage Tank Related Knowledge 1, Structure of Low Temperature Carbon Dioxide Storage Tank The low temperature carbon dioxide storage tank is generally a double-layered cylindrical structure, with the inner cylinder made of 6MnDR alloy steel and the outer cylinder of Q245R or Q345R pressure vessel steel plate. The pipeline is made of austenitic stainless steel, and the insulation layer is filled with high vacuum sintered sand or wrapped with multiple layers of insulation material. The storage tank is equipped with valves for operation, which are arranged for easy handling. Pressure gauges and level indicators are also installed to monitor the pressure and liquid level inside the tank. Low Temperature Carbon Dioxide Storage Tank 2, Key Features of Low Temperature Carbon Dioxide Storage Tank (1) The storage tank is equipped with a connection for filling with tank trucks, allowing liquid supply to vaporizers, tank trucks, and pumps. (2) Both the inner and outer cylinders of the storage tank are equipped with safety devices to ensure safe operation for users. (3) The insulation material of the low temperature carbon dioxide storage tank is specially treated to provide a longer vacuum life. Additionally, the tank is equipped with a vacuum gauge for measuring the vacuum level of the insulation layer as needed. 3, Transportation of Low Temperature Carbon Dioxide Storage Tank (1) During road transportation, the storage tank should be securely attached to the vehicle, traveling at moderate speed, and collisions with other objects are prohibited. (2) After the storage tank arrives, the unloading crew should work together with the equipment supervisor to develop a scientific and reasonable unloading plan. 4, Installation of Low Temperature Carbon Dioxide Storage Tank (1) Once the storage tank arrives at the installation site, it can be placed when conditions are suitable for installation. During the installation process, collisions and impacts are prohibited, and special attention should be given to the explosion-proof equipment of the outer cylinder and the vacuum valve, which should not be touched. (2) Perform an airtightness test on the inner cylinder system of the storage tank using nitrogen to the working pressure. After confirming that valves, pipes, flanges, etc., have no leaks, the installation is complete. (3) The installation dimensions of the low temperature carbon dioxide storage tank are specified in the supply materials. When considering filling and emptying liquids with tank trucks, the vehicle's travel path should be taken into account.
