1.相关知识 of Low-Temperature Carbon Dioxide Storage Tanks The structure of low-temperature carbon dioxide storage tanks typically consists of a double-walled cylindrical design, with the inner tube made of 6MnDR alloy steel and the outer tube 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 wrapped with multiple layers for thermal insulation. The storage tanks are equipped with valves for operation, which are arranged for ease of use. Pressure gauges and level indicators are also installed to monitor the internal pressure and liquid level of the low-temperature carbon dioxide storage tanks. 2.Main Features of Low-Temperature Carbon Dioxide Storage Tanks (1) The storage tanks are equipped with liquid filling connections for tanker trucks, enabling the supply of liquid to vaporizers, tanker trucks, and pumps. (2) Both the inner and outer cylinders of the storage tanks are equipped with safety devices to ensure safe operation for users. (3) The insulation material of the low-temperature carbon dioxide storage tanks is specially treated to provide a longer vacuum life. Additionally, the tanks are equipped with vacuum gauges for measuring the insulation space vacuum when needed. 3.Transportation of Low-Temperature Carbon Dioxide Storage Tanks (1) During road transportation, the storage tanks should be securely fastened to the vehicle, travel at moderate speeds, and avoid collisions with other objects. (2) After the storage tanks arrive, the unloading crew should work 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 tanks can be positioned once the installation conditions are met. During the installation process, avoid impacts and strikes, and pay special attention to the explosion-proof equipment on the outer cylinder and the vacuum valve, which should not be touched. (2) Perform an airtightness test on the inner cylinder system of the storage tanks using nitrogen to the working pressure. After confirming that valves, pipes, flanges, etc., are leak-free, the installation is complete. (3) The installation dimensions of the low-temperature carbon dioxide storage tanks are specified in the supply materials. When considering liquid filling and emptying with tanker trucks, account for the vehicle's travel path.

Pressure Vessel Standards: Liquid carbon dioxide storage tanks are generally considered pressure vessels, and their design, manufacture, and use should comply with the relevant pressure vessel standards. In China, common pressure vessel standards include GB150 "Steel Pressure Vessels" and GB18435 "Storage Tanks." Safety Standards: The use of liquid carbon dioxide storage tanks should comply with relevant safety standards and regulations. For instance, in China, the safe use of liquid carbon dioxide storage tanks should adhere to standards such as GB50028 "Design Code for Petroleum and Chemical Enterprises" and GB50016 "Building Design Fire Prevention Code." Inspection and Testing Standards: The inspection and testing of liquid carbon dioxide storage tanks should comply with the relevant standards and regulations. For example, the regular inspection of liquid carbon dioxide storage tanks can refer to standards like GB/T 19638 "Code for Periodic Inspection of Pressure Vessels." Environmental Protection Standards: The use of liquid carbon dioxide storage tanks should comply with relevant environmental protection standards and regulations. For instance, in China, the exhaust emissions from liquid carbon dioxide storage tanks should meet standards such as "Air Pollutant Emission Standards."

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。
