Before using a CO2 storage tank, certain inspection and filling points must be addressed. Here are some common precautions: - Inspect the tank exterior: Check for any visible damage, corrosion, or leakage signs. Ensure the tank shell is intact. - Check valves and fittings: Verify that the valves and fittings on the tank are securely fastened and there are no leaks. Ensure proper operation. - Inspect the pressure gauge: Confirm that the pressure gauge on the tank is functioning correctly and readings are accurate. Replace or repair if abnormal. - Check the level indicator: Ensure the level indicator on the tank is working properly and accurately displays the level. Repair or replace if abnormal. - Inspect the pressure relief device: Check that the pressure relief device (e.g., safety valve) on the tank is functioning correctly and the set pressure meets requirements. Repair or replace if abnormal. - Inspect the filling equipment: Verify that the filling equipment (e.g., filling pipes, pumps) is operating correctly with no leaks or blockages. Ensure safety and reliability. - Filling operations: During the filling process, note the following points: - Control the filling speed, avoiding too fast or too slow. - Control the filling pressure, not exceeding the tank's rated pressure. - Monitor the level, ensuring proper filling to the appropriate level. - Regularly inspect the filling equipment and valves to ensure normal operation. - Safety measures: Adhere to relevant safety regulations and procedures during the filling process. Operators should wear appropriate protective gear, such as static-dissipative clothing, gloves, etc. - Note that specific inspection and filling points may vary depending on the tank type and application. Before using a CO2 storage tank, check and operate according to relevant specifications and standards, and consult with experts to ensure safety and effectiveness.

When using CO2 storage tanks, pay attention to the following aspects: Safety Operation: Adhere to relevant safety operation procedures and standards to ensure operators have the necessary safety knowledge and skills. When using the tank, be mindful of preventing risks such as leaks, explosions, and fires. Pressure Control: Monitor and control the tank's pressure to ensure it remains within safe limits. Avoid exceeding the tank's rated pressure to prevent破裂 or leakage. Level Monitoring: Regularly monitor the liquid level inside the tank to ensure an adequate supply of CO2. Avoid overfilling or underfilling to maintain proper levels. Static Control Measures: Implement static control measures to prevent static buildup and discharge. Use anti-static equipment and tools to ensure static safety during operations. Tank Maintenance: Regularly inspect and maintain the tank, including the exterior, valves, and fittings. Ensure the tank remains undamaged to prevent leaks and damage. Waste Gas Management: Handle waste gases produced by CO2 storage tanks to prevent environmental pollution. Adopt appropriate waste gas management measures, such as collection and treatment. Storage Records: Document the usage of the tank, including filling dates, quantities, and inspection records. Regularly perform tank inspections and maintenance, and retain relevant records. Training and Awareness: Train operators to enhance their awareness and ability to safely operate CO2 storage tanks. Conduct regular safety training and drills to respond to emergencies. Note that the above are common precautions; specific considerations may vary depending on tank types and applications. When using CO2 storage tanks, operate according to relevant regulations and standards and consult with experts to ensure safety and effectiveness.

Low Temperature Carbon Dioxide Storage Tank Knowledge 1. Structure of Low Temperature Carbon Dioxide Storage Tank The low temperature carbon dioxide storage tank is typically a double-layered 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 sintered sand or layered with insulation material. 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. 2. Key Features of Low Temperature Carbon Dioxide Storage Tank (1) The storage tank is equipped with a liquid filling connection for tanker trucks, allowing for liquid supply to vaporizers, tanker trucks, and pumps. (2) Both the inner and outer cylinders of the storage tank are equipped with safety devices to ensure safe operation for the user. (3) The insulation material of the storage tank has been specially treated to provide a longer vacuum lifespan. Additionally, the tank is fitted with a vacuum gauge for measuring the insulation space vacuum when necessary. 3. Transportation of Low Temperature Carbon Dioxide Storage Tank (1) During road transportation, the storage tank should be securely fastened to the vehicle and travel at moderate speeds. It is prohibited to collide 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 Tank (1) Upon arrival at the installation site, the storage tank can be positioned when the installation conditions are met. During the installation process, collisions and impacts should be avoided, and special attention should be paid 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 storage tank using nitrogen to the working pressure. After confirming that there are no leaks in the valves, pipes, flanges, etc., the installation is complete. (3) The installation dimensions are as specified in the supply materials. When considering filling or emptying liquids with tanker trucks, the vehicle's travel path should be taken into account.

When handling CO2 storage tanks, static electricity is a safety issue that needs attention. Here are some methods to avoid static: - Grounding: Ensure that the tank and related equipment are properly grounded. Grounding releases static to the ground, reducing the likelihood of static buildup. Use specialized grounding equipment and grounding wires to ensure reliable grounding. - Antistatic Equipment: Use antistatic equipment such as antistatic clothing, shoes, and gloves. These items can help eliminate or reduce static buildup and protect the operator's safety. - Avoid Friction: Prevent friction during operation, especially when in contact with substances or flammable gases. Friction generates static, increasing the risk of fire or explosion. - Control Humidity: Maintain a suitable humidity level in the operating environment; higher humidity can reduce the generation and accumulation of static. Use humidifiers or other humidity control devices to adjust environmental humidity. - Avoid Plastic or Rubber Materials: Plastic and rubber materials are prone to generate static; try to avoid using these materials during operation. Choose materials with better antistatic properties for operation. - Static Dischargers: Use static dischargers to eliminate or reduce static buildup. Static dischargers neutralize static by releasing charges, reducing the danger of static. - Tank Cleaning: Regularly clean the interior of the tank to remove accumulated impurities and dirt. Pay attention to prevent the generation and accumulation of static during cleaning. Note that static avoidance methods should be determined based on specific operational environments and tank characteristics. During operation, follow relevant safety regulations and standards, and consult with experts if necessary.
