Carbon dioxide storage tanks come in various sizes and configurations, tailored to specific application and capacity requirements. Here are some common dimensions and structures of carbon dioxide storage tanks: Dimensions: The size of carbon dioxide storage tanks can range from small to large, varying with capacity. Common sizes include thousands to tens of thousands of liters. Structure: These tanks typically feature a double-walled design, with the inner wall for storing liquid carbon dioxide and the outer wall for insulation. The inner wall is usually made of stainless steel or aluminum alloy, offering excellent corrosion resistance. Insulation: To maintain the low temperature of liquid carbon dioxide, the outer wall is often insulated to reduce heat transfer and maintain低温. Insulation can be in multi-layered structures, such as polyester foam, glass wool, etc. Pressure Relief Devices: Carbon dioxide storage tanks are usually equipped with pressure relief devices, such as safety valves, to control internal pressure. The set pressure of these devices should comply with relevant requirements and be inspected and maintained regularly. Connecting Pipes: The connection between the tank and pipes is typically made using appropriate methods, such as flange or threaded connections. The connecting pipes should meet relevant standards and specifications to ensure a tight and reliable connection with no leaks. Support Structure: Large carbon dioxide storage tanks often require a support structure to bear their weight. These can be made of steel or concrete structures, ensuring stability and safety of the tank. It's important to note that the specific dimensions and structures of carbon dioxide storage tanks may vary depending on different applications and requirements. When selecting and using carbon dioxide storage tanks, one should consider the following factors...

The reason for regular inspections of low-temperature liquid carbon dioxide storage tanks is to ensure their safety performance and normal operation. Due to the storage tanks being under low temperatures and high pressures, there are certain safety risks, such as leaks and structural cracks. Regular inspections can help identify potential issues early, allowing for appropriate repairs or maintenance to ensure safe tank operation. The specific inspection frequency should be determined according to relevant regulations and standards, and it is generally recommended to conduct regular inspections and maintenance. Typically, the time interval for regular inspections of low-temperature liquid carbon dioxide storage tanks is between 1 to 3 years, which may vary depending on the tank's usage, age, design standards, and other factors. The contents of regular inspections usually include visual inspections of the tank, checks of valves and fittings, leak detection, pressure testing, and regular maintenance of the insulation layer to ensure its thermal insulation properties. It is important to note that the specific inspection frequency and contents should be determined based on local regulations, standards, and the manufacturer's recommendations. Inspections should be carried out by qualified personnel, and the results and maintenance records should be documented for tracking and managing the tank's safety performance.

According to China's "Regulations for the Safety Supervision of Pressure Vessel Technology," carbon dioxide tanks are classified as category II pressure vessels. The regulations categorize pressure vessels as follows: - Category I pressure vessels: Those with operating pressures of 10 MPa (megapascals) or more, such as steam boilers and pressure vessels. - Category II pressure vessels: Those with operating pressures of 0.1 MPa or more but less than 10 MPa, such as air compressors and liquefied gas storage tanks. - Category III pressure vessels: Those with operating pressures of 0.05 MPa or more but less than 0.1 MPa, such as storage tanks. - Category IV pressure vessels: Those with operating pressures of less than 0.05 MPa, such as gas cylinders. Based on this classification, carbon dioxide tanks typically have operating pressures above 0.1 MPa, thus falling under category II pressure vessels. It should be noted that specific classification criteria may vary depending on regional regulations and standards. When using and managing carbon dioxide tanks, it is crucial to adhere to the corresponding regulatory and standard requirements.
