When storing carbon dioxide tanks, the following requirements must be adhered to for safety and effectiveness: Ventilation: Tanks should be stored in well-ventilated areas to prevent the accumulation of carbon dioxide gas. Ensure there is adequate air circulation around the tank to avoid gas buildup and asphyxiation risks. Fire and Explosion Prevention: Keep tanks away from sources of ignition, high-temperature areas, and flammable materials. Avoid open flame operations near the tank to prevent fire and explosion risks. Sunlight Avoidance: Store tanks in locations shielded from direct sunlight to prevent overheating and pressure increase. Direct sunlight can raise tank temperatures, increasing the risk of leaks and explosions. Mechanical Damage Prevention: Keep tanks away from machinery and heavy objects to avoid collisions and damage. Mechanical damage can lead to tank leaks or破裂, causing safety hazards. Labeling and Warning Signs: Clearly label tanks with information such as the type of gas stored and pressure. Set up warning signs around the tanks to remind personnel of their presence and related safety precautions. Regular Inspections: Regularly inspect the tank's exterior, valves, and connections to ensure they are intact. Take prompt corrective actions if any abnormalities are detected. Storage Capacity Control: Control the storage capacity of the tank to prevent exceeding the rated capacity. Overfilling can cause excessive tank pressure, increasing safety risks. Storage Records: Keep records of the tank's usage, including filling dates, quantities, and inspection records. Regularly perform tank inspections and maintenance, and retain relevant records. Note that specific storage requirements may vary depending on tank type and application. When storing carbon dioxide tanks, operate according to relevant regulations and standards and consult with experts to ensure safety and effectiveness.

Prior to using a CO2 storage tank, the following preparations must be made: Safety Inspection: Conduct a safety check on the tank before use to ensure there are no visible damages, corrosion, or leaks. Inspect the tank's exterior, valves, and connecting pipes to ensure they are intact and undamaged. Tank Cleaning: Ensure the tank is clean both internally and externally. Remove any debris, dirt, and residues to ensure no substances could affect the quality or safety of the CO2. Connection Pipes: Check the connections between the tank and related pipes to ensure they are secure and sealed properly. Verify the valve and pipe's on/off status to ensure they are in the correct position. Pressure Check: Inspect the tank's pressure to ensure it is within the safe range. If necessary, use a pressure gauge or other pressure detection equipment for the check. Ventilation and Safety Measures: Ensure adequate ventilation around the tank to prevent CO2 accumulation. During operation, follow relevant safety operating procedures and measures, such as wearing personal protective equipment and avoiding open flames. Tank Labeling: Label the tank with relevant information, such as the type of gas stored, pressure rating, and capacity. This helps operators correctly identify and handle the tank. Note that these preparations may vary depending on the specific tank type and usage scenario. Before using a CO2 storage tank, it is recommended to refer to the relevant safety operation manuals and guidelines to ensure safe and correct operation.

Installation and Operation Requirements for Low-Temperature Carbon Dioxide Storage Tanks: Installation Location Selection: When selecting the installation location for the storage tank, consider the weight and dimensions of the tank to ensure a solid and stable foundation. Additionally, keep the tank away from flammable, explosive materials, and high-temperature sources to ensure safety. Safety Distance: Maintain a certain safety distance around the tank for daily inspections, maintenance, and emergency responses. The safety distance should comply with relevant safety regulations and standards. Connection Pipes: The connection between the tank and the pipes should be made using appropriate methods to ensure tight and reliable connections without leaks. The connection pipes should comply with relevant standards and specifications. Pressure Relief Device: The tank should be equipped with a pressure relief device, such as a safety valve, to control internal tank pressure. The set pressure of the pressure relief device should meet relevant requirements and be inspected and maintained regularly. Sealing Inspection: The tank's sealing performance should be checked regularly to ensure there are no leaks. Pay special attention to the sealing of valves, pipe connections, and the tank itself. Temperature Control: Low-temperature carbon dioxide storage tanks require temperature control to maintain the low internal temperature. Ensure that the surrounding environmental temperature is suitable and take appropriate insulation measures. Safety Protection: Set up appropriate safety protection facilities around the tank, such as guardrails and warning signs, to remind personnel of safety and prevent unauthorized access to the tank. Storage Capacity Control: The storage capacity of the tank should be controlled according to actual needs to avoid exceeding the rated capacity. Exceeding the rated capacity may lead to excessive tank pressure, increasing safety risks.
