清洁低温液体储罐的过程需要谨慎操作，以确保安全性和有效性。以下是一般的清洁步骤： 安全准备：在清洁液体储罐之前，确保储罐内的液体已经完全排空，并且储罐的压力已经释放。确保所有相关的安全设备和阀门处于关闭状态。 防护措施：低温液体储罐通常存储着冷的液体，如液氮或液氧。在进行清洁操作时，必须佩戴适当的个人防护装备，如绝缘手套、、防护服等，以防止冷或其他伤害。 清洁剂选择：选择适合清洁低温液体储罐的清洁剂。清洁剂应具备良好的腐蚀性能和低温适应性。可以咨询清洁剂供应商或储罐制造商以获取建议。 清洁过程：将清洁剂注入储罐中，使用适当的工具（如喷洒器、刷子等）进行清洁。根据储罐的尺寸和污染程度，可以选择手动清洁或使用清洗设备。 冲洗和排放：清洁完成后，使用清水或其他适当的冲洗剂进行冲洗，以确保清洁剂和污物。冲洗完成后，将废水和废液排放到合适的处理系统中，遵循环境保护的相关规定。 检查和验证：清洁完成后，进行储罐的检查和验证，确保储罐内部干净、无残留物，并符合相关的安全和卫生要求。 需要注意的是，清洁低温液体储罐的具体步骤和要求可能会因不同的储罐设计和使用场景而有所差异。在进行清洁操作时，应遵循相关的安全操作规程和标准，确保操作的安全性和有效性。好咨询工程师或储罐制造商以获取具体的清洁指导。

Installation and operation of low-temperature carbon dioxide storage tanks must comply with the following requirements: Installation Location Selection: When selecting the installation location for the tank, consider its weight and dimensions to ensure a solid and stable foundation. Additionally, keep it away from flammable and explosive materials and high-temperature sources to ensure safety. Safety Distance: Maintain a certain safety distance around the tank for routine inspections, maintenance, and emergency response. The safety distance should meet relevant safety regulations and standards. Connection Pipes: Use an appropriate connection method between the tank and the pipes to ensure a tight and reliable connection with no leaks. The connection pipes should comply with relevant standards and specifications. Pressure Relief Devices: The tank should be equipped with pressure relief devices, such as safety valves, to control internal pressure. The set pressure of the pressure relief devices should meet relevant requirements and be inspected and maintained regularly. Sealability Inspection: Regularly inspect the tank's sealing performance to ensure no leaks. Pay special attention to the valves, pipe connections, and the tank's own sealability. Temperature Control: Low-temperature carbon dioxide storage tanks require temperature control to maintain the internal low-temperature state. Ensure 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: Control the storage capacity of the tank according to actual needs to avoid exceeding the rated capacity. Exceeding the rated capacity may cause excessive pressure in the tank, increasing safety risks. Storage

Carbon dioxide tanks are categorized into various types and structures based on their design and application: - Vertical Tanks: Commonly used carbon dioxide tanks, these are cylindrical in shape and vertically positioned. They typically have larger capacities and are used for large-scale storage and supply. - Horizontal Tanks: Another common type, these tanks are rectangular or cylindrical in shape and horizontally placed. They are usually used for smaller-scale storage and supply, suitable for limited spaces. - Spherical Tanks: A specialized type of carbon dioxide tank with a spherical shape. They offer high strength and pressure-bearing capacity, suitable for high-pressure storage and transportation. - Vertical Tanks (Small Capacity): Smaller capacity tanks with a cylindrical shape and vertical positioning. They are typically used for small-scale storage and supply, such as commercial and residential use. - Underground Tanks: A unique structure where the carbon dioxide tank is buried underground. These tanks save space, reduce visual impact, and offer enhanced safety and environmental protection. These tanks are usually constructed from pressure-resistant materials (like carbon steel or stainless steel) with certain insulation properties and accessories such as safety valves, pressure gauges, and level indicators. The interior often features baffles or partitions to separate different liquids or gases. Additionally, the tanks are equipped with safety systems like pressure maintenance systems, leak detection systems, and fire detection systems.

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 obvious damages, corrosion, or leakage issues. Inspect the tank's appearance, valves, and connecting pipes to ensure they are intact. Tank Cleaning: Ensure the tank is clean both internally and externally. Remove any debris, dirt, and residues to ensure no substances that could affect the quality or safety of CO2 are present inside. Connecting Pipes: Check the connection between the tank and the associated pipes to ensure they are securely fastened and sealed properly. Verify the position of the valves and pipes to ensure they are in the correct state. 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 there is adequate ventilation around the tank to prevent CO2 buildup. During operation, follow relevant safety operation 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 stored gas, pressure rating, and capacity. This assists operators in correctly identifying and handling the tank. Please note that these preparations may vary depending on the type of tank and specific usage scenario. It is recommended to consult the relevant safety operation manuals and guidelines before using a CO2 storage tank to ensure safe and correct operation.
