Carbon dioxide storage tanks are categorized into various types and structures based on their design and application: - Vertical Tanks: Commonly used carbon dioxide storage tanks, these are cylindrical in shape and placed vertically. 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 placed horizontally. They are usually used for smaller-scale storage and supply, suitable for limited spaces. - Spherical Tanks: A specialized type of carbon dioxide storage tank with a spherical shape. They offer high strength and pressure-bearing capacity, suitable for high-pressure storage and transportation. - Vertical Tanks: Smaller capacity carbon dioxide storage tanks with a cylindrical shape and vertical placement. They are typically used for small-scale storage and supply, such as for commercial and residential use. - Underground Tanks: A unique structure where the carbon dioxide storage 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 thermal 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.

When using carbon dioxide tanks, the following protective procedures must be adhered to ensure safety: Tank Operator Training: All operators must receive training to understand the characteristics, operational requirements, and safety measures of carbon dioxide tanks. Training should include safe tank operation, leak handling, emergency response plans, etc. Safety Operating Procedures: Establish and follow relevant safety operating procedures, including start-up, shutdown, inspection, and maintenance of the tank. Operators should operate according to the procedures to ensure the safe operation of the tank. Leak Handling: Establish a leak handling program, including leak detection, emergency shutdown, and isolation of the leak source. Operators should be familiar with the leak handling procedures and able to respond quickly and correctly to leak incidents. Fire Prevention Measures: Carbon dioxide is flammable; fire prevention measures must be taken when using. Smoking, open flame operations, or placement of flammable materials are prohibited near the tank. Ensure that fire protection facilities around the tank are in good condition and conduct fire drills regularly. Waste Emission: When using carbon dioxide tanks, waste gases should be emitted properly to avoid the accumulation of carbon dioxide in enclosed spaces, which can cause asphyxiation and safety risks. Ensure the smooth and normal operation of the waste emission system. Regular Inspection and Maintenance: Regularly inspect the tank's appearance, sealing, valves, and pipe connections. Promptly repair or replace any abnormalities or damages. Also, regularly inspect and maintain safety valves, pressure sensors, and other accessories. Emergency Response Plan: Develop and implement an emergency response plan, including handling of leak incidents, evacuation procedures, and first aid measures. Operators should be familiar with the emergency response plan and conduct drills regularly. Monitoring and Alarm System: Install and maintain the tank's monitoring and alarm system.

Carbon dioxide storage tanks are equipment used for storing and supplying carbon dioxide gas, with the following parameters, functions, and features: Parameters: - Capacity: The capacity of carbon dioxide storage tanks can be customized to meet requirements, typically expressed in the volume of liquid carbon dioxide, such as kiloliters or cubic meters. - Pressure: The internal pressure of the tank is usually controlled within a safe range to ensure the safety of storage and supply. - Temperature: Carbon dioxide storage tanks generally need to be maintained at low temperatures to keep the carbon dioxide in a liquid state. Functions: - Storage: Carbon dioxide storage tanks can compress carbon dioxide gas into a liquid, enabling high-density storage, saving space and costs. - Supply: Carbon dioxide within the tank can be supplied to the required fields through pipelines or other means, such as the food and beverage industry, various industries, fire extinguishing, etc. Features: - Environmental and Renewable: Carbon dioxide is an environmentally friendly gas. By storing and utilizing carbon dioxide, its emissions into the atmosphere can be reduced, achieving environmental protection and sustainable development. - Safe and Reliable: During design and manufacturing, carbon dioxide storage tanks typically use high-strength materials with good pressure resistance and safety. The tank is equipped with safety valves, pressure gauges, and other accessories to ensure safe operation. - Multiple Application Fields: Carbon dioxide storage tanks are widely used in the food and beverage industry, various industries, fire extinguishing, and other fields. Carbon dioxide can be used as a food preservative, beverage effervescent agent, gas, fire extinguisher, etc., with a wide range of applications and market demand. In summary, carbon dioxide storage tanks feature high-density storage, safety and reliability, environmental and renewable qualities, and multiple application fields, making them an important device for storing and supplying carbon dioxide gas.

Common disadvantages of corrosion in pressure vessels during use include: - Chemical media: Certain chemical media are corrosive, such as acids, alkalis, salts, etc. When these media come into contact with the vessel material, corrosion may occur. - Humidity and moisture: High humidity environments or long-term exposure to moisture can lead to corrosion on the vessel surface. Particularly in the presence of oxygen, the corrosion rate may increase. - Rusting: When the protective layer on the vessel surface (such as coatings or plating) is damaged or destroyed, the vessel may be prone to rusting. Rusting can damage the vessel's surface and may lead to further corrosion. - Electrochemical corrosion: When different metals or metals and non-metals come into contact, an electrochemical corrosion battery may form. This type of corrosion can cause localized corrosion on the vessel surface. - Welding defects: Defects like weld porosity and cracks may be introduced during the welding process. These defects can become starting points for corrosion. Corrosion weakens the structural integrity of the vessel, increasing the risk of leakage or rupture. Therefore, regular inspection and maintenance of the corrosion protection layer, coating, or plating on pressure vessels are crucial. If corrosion issues are detected, prompt measures should be taken to repair or replace damaged parts. In addition, selecting appropriate materials and corrosion prevention measures, as well as proper operation and maintenance methods, can reduce the risk of corrosion in pressure vessels. Adhering to relevant safety operating procedures and standards ensures the safe operation of pressure vessels.
