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 undamaged. - Check valves and fittings: Verify that the tank's valves and fittings are securely fastened and there are no leaks. Ensure proper operation. - Inspect the pressure gauge: Confirm that the tank's pressure gauge is functioning correctly and readings are accurate. Replace or repair if abnormal. - Check the level indicator: Ensure the tank's level indicator is working properly and accurately displays the level. Repair or replace if abnormal. - Inspect the pressure relief device: Check that the tank's pressure relief device (e.g., safety valve) is functioning correctly and the set pressure meets requirements. Repair or replace if abnormal. - Inspect 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 operation: During the filling process, pay attention to the following: - 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 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-resistant 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.

The spacing regulations for carbon dioxide storage tanks are typically governed by relevant safety codes and standards, with specific spacing requirements potentially varying due to factors like location, use, and tank capacity. Here are some common spacing rules: - Small Spacing Between Tanks: Generally, the small spacing between adjacent tanks should comply with the relevant safety codes and standards. This spacing ensures that adjacent tanks are not affected in case of leakage or accidents. - Spacing Between Tanks and Buildings: The spacing between tanks and buildings also needs to adhere to the applicable regulations and standards. This ensures the building is not affected in the event of a tank leak or accident. - Spacing Between Tanks and Equipment: The spacing between tanks and other equipment (such as pipes, pumps, etc.) should also meet the relevant codes and standards. This ensures the proper operation and maintenance of the equipment. - Safety and Evacuation Routes: Adequate safety and evacuation routes should be provided around the tanks for safe evacuation in emergencies. It's important to note that specific spacing rules may vary by region and industry. Therefore, when installing and using carbon dioxide storage tanks, it's crucial to refer to local safety codes and standards and consult with experts to ensure compliance with the requirements.

Construction features of carbon dioxide storage tanks mainly include the following aspects: Material selection: Carbon dioxide storage tanks are typically made of carbon steel or stainless steel to ensure their corrosion resistance and pressure-bearing performance. Welding technology: The welding process of the tank is crucial for its quality and safety. The welding process should comply with relevant standards and specifications to ensure the quality and strength of the welds. Corrosion prevention measures: Due to the corrosive nature of carbon dioxide, both the internal and external surfaces of the tank should be treated for corrosion prevention. Common corrosion prevention measures include applying anti-corrosion paint, coating with an anti-corrosion layer, or using anti-corrosion coatings. Safety valves and pressure sensors: The tank should be equipped with safety valves and pressure sensors to monitor and control the internal pressure of the tank, ensuring safe operation. Steps for correctly installing a carbon dioxide storage tank are as follows: Site preparation: Select an appropriate site for installation, ensuring the site is level, stable, and meets safety distance requirements. Clear the site to ensure there are no obstructions or fire sources. Foundation construction: Construct the foundation according to the size and weight of the tank. The foundation should have sufficient strength and stability to support the weight and pressure of the tank. Tank installation: Place the tank on the foundation, ensuring there is appropriate padding and fastening devices between the tank and the foundation. Connect and secure the tank according to its design requirements. Pipe connection: Connect the tank to the piping system as needed. Ensure that the connections are sealed properly to prevent leaks. Safety equipment installation: Install the required safety equipment for the tank, such as safety valves, pressure sensors, temperature sensors, etc. Ensure these facilities are properly installed and connected.

Common defects in CO2 storage tanks that may deform during use include: Overpressure: When the internal pressure of the tank exceeds its design pressure, it may lead to deformation. This could be due to operator error, system failure, or other causes. Temperature Fluctuations: CO2 storage tanks expand and contract with temperature changes, and excessive or rapid temperature changes can cause deformation. Internal Corrosion: If there are corrosion issues inside the tank, corrosion can damage the structural integrity, resulting in deformation. External Damage: External impacts, compression, or other physical damage can cause the tank to deform. Incorrect Installation or Use: Incorrect installation or usage methods can cause uneven stress on the tank, leading to deformation. Tank deformation can reduce the structural integrity of the tank and even pose a risk of leakage or rupture. Therefore, it is important to regularly inspect and maintain the integrity of the tank, as well as to follow proper operational and installation procedures. If tank deformation or other defects are detected, the tank should be immediately disused and professional assistance should be sought for inspection and repair. Do not attempt to repair or continue using a defective tank to ensure operational safety.
