When storing carbon dioxide tanks, the following requirements must be followed to ensure safety and effectiveness: Ventilation: Tanks should be stored in well-ventilated areas to prevent the accumulation of carbon dioxide gas. Ensure adequate air circulation around the tanks to avoid gas buildup and asphyxiation risks. Fire and Explosion Prevention: Keep tanks away from ignition sources, high-temperature areas, and flammable materials. Avoid open flame activities near tanks to prevent fire and explosion risks. Sunlight Avoidance: Store tanks in locations shielded from direct sunlight to prevent overheating and pressure increase. Direct sunlight can raise tank temperatures, increasing the risk of leaks and explosions. Mechanical Damage Prevention: Keep tanks away from machinery and heavy objects to avoid collisions and damage. Mechanical damage can lead to tank leaks or ruptures, causing safety hazards. Labeling and Warning Signs: Clearly label tanks with information such as the type of gas stored and pressure. Set up warning signs around the tanks to remind personnel of their presence and related safety precautions. Regular Inspections: Conduct regular inspections of the tank's exterior, valves, and connections to ensure they are intact. Take prompt corrective actions if any abnormalities are found. Storage Capacity Control: Control the storage capacity of the tanks to prevent exceeding the rated capacity. Overfilling can lead to excessive tank pressure, increasing safety risks. Storage Records: Keep records of the tank's usage, including filling dates, quantities, and inspection records. Regularly inspect and maintain the tanks, and retain relevant records. It should be noted that specific storage requirements may vary depending on tank type and application. When storing carbon dioxide tanks, operate in accordance with relevant regulations and standards, and consult with experts to ensure safety and effectiveness.

Pressure Vessel Standards: Liquid carbon dioxide storage tanks are generally considered pressure vessels, and their design, manufacture, and use must comply with the relevant pressure vessel standards. In China, common pressure vessel standards include GB150 "Steel Pressure Vessels" and GB18435 "Storage Tanks". Safety Standards: The use of liquid carbon dioxide storage tanks must adhere to relevant safety standards and regulations. For instance, in China, the safe operation of liquid carbon dioxide storage tanks should follow standards such as GB50028 "Design Code for Petroleum and Chemical Industry Enterprises" and GB50016 "Design Code for Fire Prevention in Buildings". Inspection and Testing Standards: The inspection and testing of liquid carbon dioxide storage tanks must comply with the applicable standards and regulations. For example, regular inspections of liquid carbon dioxide storage tanks can refer to standards like GB/T 19638 "Regulations for Periodic Inspection of Pressure Vessels". Environmental Protection Standards: The use of liquid carbon dioxide storage tanks must comply with relevant environmental protection standards and regulations. For instance, in China, the exhaust emissions from liquid carbon dioxide storage tanks should meet standards such as "Emission Standards for Air Pollutants".

When applying coatings to carbon dioxide storage tanks, several issues should be addressed: - Surface Preparation: Prior to coating, thorough surface preparation is essential. This involves cleaning the surface, removing grease, dirt, and old coatings to ensure proper adhesion and quality of the coating. - Paint Selection: Choosing the right paint for carbon dioxide storage tanks is crucial. The paint should be corrosion-resistant, heat-resistant, and chemical-resistant to protect the tank surface from corrosion and damage. - Spraying Techniques: The selection and operation of spraying techniques are vital for the quality and evenness of the coating. Appropriate spraying equipment and methods should be chosen to ensure even coverage of the entire tank surface and avoid drips and runs. - Coating Thickness: The thickness of the coating is critical for the tank's protection. The thickness should be controlled according to the paint requirements and the tank's operating environment to ensure the coating's protective performance and lifespan. - Drying and Curing: After the coating is applied, sufficient time must be allowed for drying and curing. Follow the correct drying time and conditions as specified by the paint to ensure the quality and performance of the coating. - Safety Measures: Appropriate safety measures must be taken during the spraying process, including wearing protective eyewear, respirators, and protective clothing to ensure the safety of the operators. - Quality Inspection: After coating is completed, a quality inspection should be conducted, including the appearance, adhesion, and thickness of the coating. Any issues or defects should be repaired and addressed promptly. It is important to note that the coating of carbon dioxide storage tanks should be carried out by professionals.

Carbon dioxide storage tanks are categorized into various types and structures based on their design and application: - Vertical Tanks: Commonly used carbon dioxide storage tanks, these are cylindrical in shape and placed vertically. They typically have larger capacities and are used for large-scale storage and supply. - Horizontal Tanks: Another common type, these tanks are rectangular or cylindrical in shape and placed horizontally. They are usually used for smaller-scale storage and supply, suitable for limited spaces. - Spherical Tanks: A specialized type of carbon dioxide storage tank, spherical in shape. These tanks offer high strength and pressure-bearing capacity, suitable for high-pressure storage and transportation. - Vertical Tanks: Smaller capacity carbon dioxide storage tanks, cylindrical in shape and placed vertically. They are commonly used for small-scale storage and supply, such as for commercial and residential use. - Underground Tanks: A unique structure where carbon dioxide storage tanks are buried underground. These tanks save space, reduce visual impact, and offer enhanced safety and environmental protection. These tanks are typically made of pressure-resistant materials (like carbon steel or stainless steel) with certain thermal insulation properties and accessories such as safety valves, pressure gauges, and level indicators. The interior usually features baffles or partitions to separate different liquids or gases. Additionally, the tanks are equipped with safety systems like pressure maintenance systems, leak detection systems, and fire detection systems.
