Carbon dioxide level gauges are devices used to measure and monitor the liquid level of carbon dioxide within storage tanks. Depending on different working principles and application requirements, common types of carbon dioxide level gauges include the following: - Buoy Level Gauge: Uses the floating and sinking of a buoy to reflect the liquid level. The liquid level is measured through a mechanical device or an electrical signal sensor connected to the buoy. - Pressure Level Gauge: Utilizes the relationship between liquid pressure and liquid level to measure the level. The liquid level height is calculated by measuring the pressure change on a pressure sensor. - Ultrasonic Level Gauge: Uses the propagation time of ultrasound to measure the liquid level. An ultrasonic transmitter emits ultrasound, and when the beam encounters the liquid surface, part of the beam is reflected back. The liquid level height is calculated by measuring the reflection time. - Capillary Level Gauge: Uses the capillary principle to measure the liquid level. By inserting a thin tube into the liquid, the liquid rises within the tube. The liquid level height is calculated based on the rise in the liquid. - Level Gauge: Utilizes wave reflection to measure the liquid level. The transmitter emits waves, and when the beam encounters the liquid surface, part of the beam is reflected back. The liquid level height is calculated by measuring the reflection time. The application of these level gauges in carbon dioxide storage tanks can be selected based on specific requirements and tank design. When selecting and installing level gauges, factors such as the properties of the liquid, working environment, and precision requirements should be considered, and it must ensure compatibility with the tank's safe operation and monitoring system.

Carbon dioxide storage tanks feature the following characteristics: - High-pressure Storage: Carbon dioxide storage tanks are typically used for high-pressure storage and can withstand significant pressure. The CO2 inside the tank exists in a gaseous or liquid state, with pressures usually ranging from tens to hundreds of MPa (Megapascals). - High-Density Storage: When stored in a liquid state, CO2 has a higher storage density. Compared to gaseous storage, liquid storage allows for more CO2 to be stored in a relatively smaller tank, enhancing storage efficiency. - Corrosiveness: Carbon dioxide has some corrosive properties and can erode certain materials. Therefore, carbon dioxide storage tanks are commonly made from corrosion-resistant materials like stainless steel or alloy steel to ensure durability and safety. - Temperature Sensitivity: CO2 is in a gaseous state at room temperature but can convert to a liquid state at lower temperatures. As a result, carbon dioxide storage tanks usually require insulation to maintain a low internal temperature. - Safety Protection: Storage tanks are equipped with safety valves and pressure relief devices to control internal pressure and temperature, ensuring the safety of the storage process. Additionally, the tanks must have good sealing properties to prevent leaks. - Wide Application: Carbon dioxide storage tanks are widely used in various industries such as food and beverage, pharmaceutical, and chemical industries. They can be used for freezing food, refrigeration equipment, gas supply, and more, meeting diverse industrial needs. In summary, carbon dioxide storage tanks possess features such as high-pressure and high-density storage, corrosiveness, temperature sensitivity, safety protection, and wide application. These characteristics make them essential equipment for storing and using CO2 in numerous industries.

Carbon dioxide storage tank spacing regulations are typically governed by relevant safety codes and standards, with specific spacing requirements varying depending on factors like location, use, and tank capacity. Below are some common spacing rules: 1. Small spacing between tanks: Generally, the small spacing between adjacent tanks should comply with the relevant safety codes and standards. This spacing ensures that neighboring tanks are not affected in case of leakage or accidents. 2. Spacing between tanks and buildings: The spacing between tanks and buildings must also adhere to the relevant codes and standards. This distance ensures that the buildings are not compromised in the event of tank leakage or accidents. 3. Spacing between tanks and equipment: The spacing between tanks and other equipment (such as pipelines, pumps, etc.) should also comply with the relevant codes and standards. This spacing ensures the proper operation and maintenance of the equipment. 4. Safety and evacuation routes: Sufficient safety and evacuation routes should be provided around the tanks for personnel to safely evacuate during 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, refer to local safety codes and standards and consult with experts to ensure compliance with the relevant requirements.

Low-temperature CO2 storage tanks are equipment used for storing and transporting low-temperature liquid CO2. Here are some facts about low-temperature CO2 storage tanks: Tank Structure: These tanks typically feature a double-walled design, with the inner wall for liquid CO2 storage and the outer wall for insulation. The interior is usually made of stainless steel or aluminum alloy, offering excellent corrosion resistance. Storage Temperature: The storage temperature for these tanks usually ranges from -40°C to -196°C, depending on specific application requirements. Temperature control is crucial for maintaining the stability and safety of the liquid CO2. Storage Capacity: The capacity of low-temperature CO2 storage tanks can be chosen based on actual needs, typically ranging from a few thousand to tens of thousands of liters. The capacity selection should consider storage requirements, supply frequency, and spatial constraints. Safety Protection: These tanks require safety protection devices, such as pressure relief valves, pressure sensors, and temperature sensors, to ensure internal pressure and temperature remain within safe limits. Transportation: Low-temperature CO2 storage tanks can be transported via road, rail, or ship. Proper insulation measures must be taken during transportation to maintain the low-temperature state of the liquid CO2 inside. Safe Operation: Operation of low-temperature CO2 storage tanks requires training and adherence to safety operating procedures. Operators should be familiar with the tank's characteristics and safety precautions to ensure safe and effective operation. Regular Inspection and Maintenance: Regular inspection and maintenance are necessary for low-temperature CO2 storage tanks, including visual inspections, valve and pipe checks, and pressure relief device checks. Regular maintenance ensures the tank operates normally and safely. The above information covers some key facts about low-temperature CO2 storage tanks. When using and operating these tanks, it is essential to follow relevant safety standards and consult with experts to ensure safety and effectiveness.
