Carbon dioxide storage tanks possess the following safety technical characteristics: - High-strength materials: These tanks are typically made of high-strength steel or alloy materials to withstand stresses and loads under high pressure and low-temperature environments. - Safety valves and pressure relief devices: Equipped with safety valves and pressure relief devices to control internal tank pressure and prevent overpressure and explosions. When the internal pressure exceeds the set value, the safety valve will automatically open to release pressure. - Insulation layer: The tank interior is lined with an insulation layer to minimize heat transfer and liquid evaporation. The insulation layer usually consists of a multi-layer structure, including thermal insulation materials and an external protective layer, to maintain stable internal temperatures. - Level monitoring and control: The tank is fitted with level monitoring devices to monitor internal liquid levels. Timely monitoring and control ensure the liquid storage within the tank remains within a safe range. - Fire and explosion prevention measures: The tank implements fire and explosion prevention measures such as fire-resistant coatings, fire separation areas, and explosion-proof devices to prevent fires and explosions. - Leak detection and alarm system: The tank is equipped with a leak detection and alarm system for the timely detection and alerting of any leaks. Rapid response and handling can reduce the safety risks caused by leaks. - Regular inspections and maintenance: Regular inspections and maintenance are required, including visual inspections, valve maintenance, and pressure tests, to ensure the tank's safety performance and reliability. It should be noted that the specific safety technical characteristics of carbon dioxide storage tanks may vary depending on the type of tank and application. When using a carbon dioxide storage tank, relevant regulations and standards should be followed.

Low-Temperature Carbon Dioxide Storage Tank Knowledge 1. Structure of Low-Temperature Carbon Dioxide Storage Tank The low-temperature carbon dioxide storage tank typically features a double-walled cylindrical structure. The inner cylinder is made of 6MnDR alloy steel, while the outer cylinder is constructed from Q245R or Q345R pressure vessel steel plates. The pipeline is made of austenitic stainless steel, and the jacket is filled with high-vacuum pearlite sand or insulated with multi-layer wrapping. The storage tank is equipped with valves for operation, arranged for ease of use. It also features a pressure gauge and a level indicator for monitoring the pressure and liquid level inside the tank. 2. Key Features of Low-Temperature Carbon Dioxide Storage Tank (1) The tank is equipped with a connection for filling with trucks, allowing liquid supply to vaporizers, tank trucks, and pumps. (2) Both the inner and outer cylinders are equipped with safety devices to ensure safe operation for users. (3) The insulating material in the tank has been specially treated to extend the vacuum life of the low-temperature carbon dioxide storage tank. It also includes a vacuum gauge for measuring the jacket vacuum when necessary. 3. Transportation of Low-Temperature Carbon Dioxide Storage Tank (1) During road transportation, the tank should be securely attached to the vehicle and travel at moderate speeds. It is forbidden to collide with other objects. (2) After arrival, the unloading personnel should work together with the equipment supervisor to formulate a scientific and reasonable unloading plan. 4. Installation of Low-Temperature Carbon Dioxide Storage Tank (1) Once the tank arrives at the installation site, it can be positioned when the installation conditions are met. During the installation process, collision and impact should be avoided, and special attention should be paid to the explosion-proof equipment on the outer cylinder and the vacuum valve, which must not be touched. (2) Perform a gas-tightness test on the inner cylinder system using nitrogen to the working pressure. After checking that valves, pipelines, flanges, etc., are leak-free, the installation is complete. (3) The installation dimensions are as specified in the supply materials. When considering filling or emptying liquids with tank trucks, the vehicle's travel route should be taken into account.

Before using a CO2 storage tank, certain inspection and filling points must be addressed. Here are some common considerations: - 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: Check if the pressure gauge on the tank is functioning correctly and providing accurate readings. 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 if the pressure relief device (e.g., safety valve) on the tank is operating 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 functioning properly with no leaks or blockages. Ensure safety and reliability. - Filling operation: During the filling process, pay attention to the following: - Control the filling rate, avoiding too fast or too slow. - Control the filling pressure, not exceeding the tank's rated pressure. - Monitor the level to ensure proper filling. - 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-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.
