Carbon dioxide storage tanks possess the following characteristics: - High-pressure Vessel: Carbon dioxide storage tanks are typically designed as high-pressure vessels, capable of withstanding significant pressure. This is due to the fact that carbon dioxide requires high pressure at room temperature to maintain a liquid state. - High Oxidizing Properties: Carbon dioxide has high oxidizing properties, supporting combustion. Therefore, when handling and storing carbon dioxide, precautions must be taken to prevent contact to avoid fire and explosion risks. - Low-Temperature Storage: Carbon dioxide is gaseous at room temperature but can be compressed into a liquid at lower temperatures. Thus, carbon dioxide storage tanks usually need excellent insulation to maintain the低温 of stored liquid carbon dioxide. - High Density: Liquid carbon dioxide has a high density, allowing for the storage of large amounts of carbon dioxide in a relatively small volume. This makes carbon dioxide storage tanks useful in scenarios requiring substantial carbon dioxide supply. - Safety Valves and Pressure Control: To ensure the internal pressure of the tank remains within a safe range, carbon dioxide storage tanks are often equipped with safety valves and pressure control devices. These devices monitor and control the internal pressure to prevent excessive pressure from causing tank rupture. - Corrosiveness: Carbon dioxide has some corrosive properties, particularly in high humidity environments. Therefore, the materials and corrosion prevention measures for the tank need to consider the corrosiveness of carbon dioxide to ensure the tank's durability and safety. These characteristics make carbon dioxide storage tanks widely applicable in various industries, such as the food and beverage industry, manufacturing, firefighting, and the gas industry. When using carbon dioxide storage tanks, it is essential to follow relevant safety operation procedures and standards to ensure operational safety.

Carbon dioxide tanks are devices used for storing carbon dioxide gas. They are typically made of high-strength materials with sealing capabilities to prevent any leakage of stored CO2. The design and capacity of the tanks can be adjusted to meet various application needs. Carbon dioxide tanks are widely used across industries such as industrial production, food processing, etc. In the industrial sector, they are commonly used for storing and supplying CO2 gas for processes like welding, gas shielding, and fire suppression. In the food processing industry, they can be used to produce carbonated beverages, frozen foods, and more. In the medical field, carbon dioxide tanks can be used to produce medical gases like breathing gas and anesthetic gases. The development and manufacturing of carbon dioxide tanks involve multiple manufacturers and technologies. Different companies may employ various designs and manufacturing processes to cater to different user requirements. Additionally, relevant safety standards and regulations must be adhered to ensure the safe operation and use of the tanks.

Carbon dioxide storage tank specifications can vary depending on design and application requirements. Here are some common standard parameters: - Tank Capacity: The capacity of carbon dioxide storage tanks is typically expressed in kiloliters (L) or cubic meters (m), ranging commonly from a few thousand to tens of thousands of liters. - Working Pressure: The working pressure of carbon dioxide storage tanks is usually around 20 to 25 MPa at normal temperatures, with specific pressure determined by application needs and design standards. - Design Temperature: The design temperature for carbon dioxide storage tanks is usually within a low-temperature range, generally between -40°C to -60°C, to accommodate the liquefaction and storage requirements of CO2. - Material: Carbon dioxide storage tanks are commonly made of high-strength steel or alloy materials to withstand the stresses and loads under high-pressure and low-temperature conditions. - Insulation: The interior of the tank is equipped with an insulation layer to reduce heat transfer and liquid evaporation. The insulation is typically a multi-layered structure, including insulating materials and an external protective layer. - Safety Valve and Pressure Relief Devices: Tanks are fitted with safety valves and pressure relief devices to control internal pressure and prevent overpressure and explosions. - Level Monitoring and Control: The tank is equipped with level monitoring devices to monitor the liquid level inside. Timely monitoring and control of the level ensure that the liquid stored within the tank remains within a safe range. Note that specific carbon dioxide storage tank specifications may vary due to different design standards, application requirements, and manufacturers. When selecting and using carbon dioxide storage tanks, it is important to consider these factors.

The application standards for liquid carbon dioxide storage tanks mainly include the following aspects:
