Low Temperature Carbon Dioxide Storage Tank Related Knowledge 1, Structure of Low Temperature Carbon Dioxide Storage Tank: The storage tank is typically a double-walled cylindrical structure, with the inner cylinder made of 6MnDR alloy steel and the outer cylinder of Q245R or Q345R pressure vessel steel plate. The piping is made of austenitic stainless steel, and the insulation space is filled with high vacuum pearlite sand or wrapped with multiple layers for thermal insulation. The storage tank is equipped with valves for operation, which are arranged for ease of use. It also features a pressure gauge and a level gauge for monitoring the pressure and liquid level inside the tank. Low Temperature Carbon Dioxide Storage Tank 2, Key Features: (1) The tank is equipped with a liquid filling connection for tanker trucks, allowing supply to vaporizers, tanker trucks, and pumps. (2) Both the inner and outer cylinders of the tank are equipped with safety devices to ensure safe operation. (3) The insulation material of the tank has been specially treated to provide a longer vacuum life, and it is also equipped with a vacuum gauge for measuring the insulation space vacuum when needed. 3, Transportation of Low Temperature Carbon Dioxide Storage Tank: (1) During road transportation, the tank should be securely fastened to the vehicle, travel at moderate speeds, and avoid collisions with other objects. (2) After arrival, the unloading personnel should work with the equipment supervisor to develop a scientific and reasonable unloading plan. 4, Installation of Low Temperature Carbon Dioxide Storage Tank: (1) Upon arrival at the installation site, the tank can be positioned when installation conditions are met. During installation, avoid impacts and strikes, and pay special attention to the explosion-proof equipment on the outer cylinder and the vacuum valve, which should not be touched. (2) Perform a gas-tightness test on the inner cylinder system of the tank using nitrogen to working pressure, and upon confirming that valves, pipes, flanges, etc., are leak-free, the installation is complete. (3) The installation dimensions are as per the supply materials. When liquid filling and draining are required using tanker trucks, consider the vehicle's travel path.

An automated maintenance system for carbon dioxide storage tanks typically includes the following main components: - Pressure Maintenance System: Monitors and adjusts the internal pressure of the tank to ensure carbon dioxide within remains within a safe and stable pressure range. This system includes pressure sensors, control systems, pressure regulating valves, and pressure reserve devices. - Temperature Control System: Monitors and adjusts the internal temperature of the tank to maintain carbon dioxide within an appropriate temperature range. The system includes temperature sensors, control systems, and temperature regulating devices. - Level Monitoring System: Measures and monitors the liquid level within the tank to ensure the carbon dioxide level stays within a safe range. This system can utilize float level gauges, pressure level gauges, and ultrasonic level gauges. - Leak Detection System: Monitors for leaks in the tank and pipeline systems, enabling timely detection and alarms. The system can employ gas sensors, liquid sensors, and leak alarms. - Fire Detection and Extinguishing System: Monitors for fires in the tank area and takes appropriate extinguishing measures. The system includes fire detectors, alarms, and extinguishing equipment. - Remote Monitoring and Control System: Remotely monitors and controls the operational status and parameters of the tank, enabling remote operation and management. This system connects via network, providing real-time data and remote control functions. These are the main components of a typical automated maintenance system for carbon dioxide storage tanks. Specific system configurations and functions can be customized according to the tank's design requirements and application scenarios. These automated maintenance systems enhance the tank's safety, stability, and reliability, reducing the need for manual intervention and operational risks.

When using a 50-cubic-liter liquid oxygen tank, the following safety precautions should be observed: Fire and Explosion Prevention: Liquid oxygen is highly oxidizing and can support combustion. Therefore, avoid contact and ensure there are no open flames or other ignition sources nearby. Ventilation: When liquid oxygen evaporates, it produces a large amount of oxygen, so good ventilation around the tank is necessary to prevent oxygen accumulation and the risk of explosion. Avoid High Temperatures: Liquid oxygen may cause combustion or explosion when in contact with high-temperature objects. Hence, avoid exposing the liquid oxygen tank to high-temperature environments or contact with hot objects. Pressure Control: Use the liquid oxygen tank according to its designed pressure and flow rate, and avoid exceeding its load-bearing capacity. Regularly inspect and maintain the safety valve to ensure proper functioning and prevent overpressure. Corrosion Prevention: Regular inspections and maintenance of the liquid oxygen tank should be conducted to prevent corrosion. Especially, keep the tank surface and contact areas dry and clean to avoid corrosion. Safe Operation: Operators should receive relevant training to understand the safety operating procedures and standards for the liquid oxygen tank. Follow proper operational procedures, wear personal protective equipment, and ensure safe operation. Emergency Preparedness: Establish an emergency response plan and equip with appropriate fire-fighting and first-aid equipment when using the liquid oxygen tank. Operators should be familiar with the emergency procedures and be able to respond promptly to emergencies. Note that the above safety precautions are general recommendations. Specific safety operations should be based on the design and usage requirements of the liquid oxygen tank. Before using the liquid oxygen tank, it is recommended to refer to relevant safety operation manuals and guidelines to ensure operational safety.
