Carbon dioxide storage tanks are equipment used for storing and transporting carbon dioxide (CO2). They are typically sealed containers with specialized design and structure to ensure safe storage and use of CO2. Here are some common details about carbon dioxide storage tanks: Storage Form: CO2 is a gas at room temperature but can be compressed into a liquid under high pressure for easier storage and transport. Storage tanks for CO2 usually hold liquid CO2. Storage Pressure: These tanks commonly store high-pressure CO2 at around 20-25 bar, which helps maintain the liquid state. Storage Capacity: The capacity of CO2 storage tanks varies from a few thousand liters to tens of thousands of liters, depending on specific application needs. Safety: CO2 is odorless and colorless, but at high concentrations, it can be dangerous, causing asphyxiation. Appropriate safety measures, such as ventilation and protective gear, are necessary when using CO2 storage tanks to ensure the safety of operators. Applications: Carbon dioxide storage tanks are widely used across various industries, including food and beverage, manufacturing, fire suppression, and gas supply. They store and supply CO2 to meet diverse industry needs. It is important to note that the design, manufacturing, and use of CO2 storage tanks must comply with relevant regulations, standards, and safety guidelines. Operators should follow the manual and safety guidelines, and cooperate with local regulatory bodies to ensure the tank's safety and reliability.

Carbon dioxide storage tanks feature the following safety technical characteristics: - High-strength materials: Carbon dioxide tanks are typically made of high-strength steel or alloy materials to withstand stress and loads under high pressure and low-temperature environments. - Safety valves and pressure relief devices: The tank is equipped with safety valves and pressure relief devices to control internal pressure and prevent overpressure and explosions. When the internal pressure exceeds the set value, the safety valve will automatically open to release pressure. - Insulation layer: The tank is internally insulated to reduce heat transfer and liquid evaporation. The insulation layer usually consists of multi-layer structures, including thermal insulation materials and an external protective layer, to maintain stable internal temperatures. - Level monitoring and control: The tank is fitted with level monitoring devices to monitor the liquid level within the tank. Timely monitoring and control of the level ensure that the liquid storage volume within the tank remains within a safe range. - Fire and explosion prevention measures: The tank employs fire and explosion prevention measures such as fire-resistant coatings, fire isolation areas, and explosion-proof devices to prevent fires and explosions. - Leak detection and alarm system: The tank is equipped with a leak detection and alarm system to promptly detect and alert of any leakage. Quick response and handling can minimize the safety risks caused by leaks. - Regular inspections and maintenance: Tanks require regular inspections and maintenance, including visual inspections, valve maintenance, and pressure testing. Regular maintenance ensures the safety performance and reliability of the tank. - It should be noted that the specific safety technical characteristics of carbon dioxide storage tanks may vary depending on the type of tank and its application. When using carbon dioxide storage tanks, relevant regulations and standards should be followed.

Low-temperature CO2 storage tanks are equipment used for storing and transporting low-temperature liquid CO2. Here are some facts about low-temperature CO2 storage tanks: Tank Structure: These tanks typically feature a double-walled design, with the inner wall for storing liquid CO2 and the outer wall for insulation. The interior is usually made of stainless steel or aluminum alloy, offering excellent corrosion resistance. Storage Temperature: The storage temperature usually ranges from -40°C to -196°C, depending on specific application requirements. Temperature control is crucial for maintaining the stability and safety of the liquid CO2. Storage Capacity: The capacity of low-temperature CO2 storage tanks can be selected based on actual needs, ranging from a few thousand to tens of thousands of liters. The choice of capacity should consider storage requirements, supply frequency, and spatial constraints. Safety Protection: These tanks require safety equipment such as pressure relief devices (e.g., safety valves), pressure sensors, and temperature sensors to ensure internal pressure and temperature remain within safe limits. Transportation: Low-temperature CO2 storage tanks can be transported via road, rail, or ship. Proper insulation measures must be taken during transport to maintain the低温 state of the liquid CO2 inside. Safe Operation: The operation of low-temperature CO2 storage tanks requires training and adherence to safety protocols. Operators should understand the tank's characteristics and safety precautions to ensure safe and effective operation. Regular Inspections and Maintenance: Regular inspections and maintenance are necessary for low-temperature CO2 storage tanks, including visual inspections, valve and pipeline checks, and pressure relief device checks. Regular maintenance ensures the tank operates normally and safely. The above information covers some key facts about low-temperature CO2 storage tanks. When using and operating these tanks, it is essential to follow relevant safety regulations and standards, and consult with experts to ensure safety and effectiveness.

The spacing rules for carbon dioxide storage tanks are typically governed by relevant safety codes and standards, with specific spacing requirements potentially varying due to factors such as location, usage, and tank capacity. Here are some common spacing rules: - Small Spacing Between Tanks: Generally, the small spacing between adjacent tanks should comply with applicable safety codes and standards. This spacing ensures that neighboring tanks are not affected in the event of a leak or accident. - Spacing Between Tanks and Buildings: The spacing between tanks and buildings must also adhere to relevant codes and standards. This spacing ensures that buildings are not compromised in case of a tank leak or accident. - Spacing Between Tanks and Equipment: The spacing between tanks and other equipment (such as pipelines, pumps, etc.) should also meet the relevant codes and standards. This spacing ensures the proper operation and maintenance of equipment. - Safety and Escape Routes: Sufficient safety and escape routes should be provided around and between tanks to allow for safe evacuation during emergencies. It's important to note that specific spacing rules may vary depending on different regions and industries. Therefore, when installing and using carbon dioxide storage tanks, it is crucial to refer to local safety codes and standards and consult with experts to ensure compliance.
