Low Temperature Carbon Dioxide Storage Tank Related Knowledge 1. Structure of Low Temperature Carbon Dioxide Storage Tank Low temperature carbon dioxide storage tanks are typically double-walled cylindrical structures, 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 sintered sand or layered insulation. The storage tank is equipped with operation valves for ease of use, as well as pressure gauges and level indicators for monitoring internal pressure and liquid level. 2. Key Features of Low Temperature Carbon Dioxide Storage Tanks (1) The storage tank has a liquid filling connection for tank trucks, allowing supply to vaporizers, tank trucks, and pumps. (2) Both the inner and outer cylinders are equipped with safety devices to ensure safe operation for users. (3) The insulation material is specially treated to extend the vacuum life of the storage tank. Additionally, the tank is equipped with a vacuum gauge for measuring the insulation space vacuum when needed. 3. Transportation of Low Temperature Carbon Dioxide Storage Tanks (1) During road transportation, the storage 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 together with the equipment supervisor to develop a scientific and reasonable unloading plan. 4. Installation of Low Temperature Carbon Dioxide Storage Tanks (1) Upon arrival at the installation site, the storage tank can be positioned when installation conditions are met. During the installation process, avoid impacts and collisions, 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 using nitrogen to the working pressure. After checking that valves, pipes, flanges, etc., have no leaks, the installation is complete. (3) The installation dimensions are as per the supply materials. When considering liquid loading and unloading with tank trucks, consider the vehicle's travel lanes.

The 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 that the carbon dioxide inside remains within a safe and stable pressure range. This system comprises 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 the carbon dioxide at an appropriate temperature range. The system includes temperature sensors, control systems, and temperature regulation devices. - Level Monitoring System: Measures and monitors the liquid level inside the tank to ensure the carbon dioxide level remains within a safe range. This system can utilize float level gauges, pressure level gauges, and ultrasonic level gauges. - Leak Detection System: Monitors leaks in the tank and pipeline systems, enabling timely detection and alarm. The system can employ gas sensors, liquid sensors, and leak alarms. - Fire Detection and Extinguishing System: Monitors fire conditions in the tank area and takes appropriate extinguishing measures. The system includes fire detectors, alarms, and extinguishing equipment. - Remote Monitoring and Control System: Allows remote monitoring and control of the tank's operational status and parameters, enabling remote operation and management. This system can connect via network to provide real-time data and remote control functions. These are the main components of a typical automated maintenance system for carbon dioxide storage tanks. The specific system configuration 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 concerns should be noted: - Fire and Explosion Prevention: Liquid oxygen is highly oxidizing and can support combustion. Therefore, avoid contact and ensure there is no open flame or other ignition sources in the vicinity of the tank. - Ventilation: When liquid oxygen evaporates, it produces a large amount of oxygen. Thus, good ventilation around the tank is essential 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. Therefore, avoid exposing the liquid oxygen tank to high-temperature environments or contact with hot objects. - Prevent Overpressure: Use the liquid oxygen tank in accordance with its designed pressure and flow rates, avoiding exceeding its capacity. Regularly inspect and maintain the safety valve to ensure proper operation and prevent overpressure. - Prevent Corrosion: Regular inspection and maintenance of the liquid oxygen tank should be conducted to prevent corrosion issues. Particularly, keep the surface and contact areas dry and clean to avoid corrosion. - Safe Operation: Operators should receive relevant training and understand the safe operating procedures and standards for liquid oxygen tanks. Follow correct operational protocols, wear personal protective equipment, and ensure safety during operations. - Emergency Preparedness: Establish an emergency response plan and equip with appropriate fire extinguishing and first-aid equipment when using the liquid oxygen tank. Operators should be familiar with the emergency procedures and capable of responding quickly to emergencies. Note that the above safety concerns are general suggestions only. 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.
