Chengjie Special Equipment Co., Ltd. is a manufacturer of low-temperature liquid storage tanks, offering design, manufacturing, and installation services for low-temperature liquid CO2 storage tanks. Here's an overview of Chengjie Special Equipment's low-temperature liquid CO2 storage tanks: Tank Type: Chengjie's low-temperature liquid CO2 storage tanks are typically designed as vertical or horizontal, chosen based on customer needs and site conditions. Material: The tanks are mainly made of low-temperature steel, providing excellent corrosion and low-temperature resistance. Insulation Layer: The tanks are internally insulated to minimize heat transfer and liquid evaporation. The insulation is usually a multi-layered structure, including thermal insulation material and an outer protective layer. Safety Valve and Pressure Relief Device: Equipped with a safety valve and pressure relief device, the tanks are designed to control internal pressure and prevent overpressure and explosion. Liquid Level Indicator: A liquid level indicator is installed in the tank to monitor the liquid level, ensuring the control and management of liquid storage. Safety Measures: Chengjie's low-temperature liquid CO2 storage tanks comply with relevant safety regulations and standards and implement various safety measures, such as fire and explosion prevention, leak detection, and alarm systems. Customized Design: Chengjie Special Equipment can provide customized design and manufacturing services according to customer needs and application scenarios to meet the specific requirements of different clients.

The liquid level of carbon dioxide tanks will vary depending on specific design and operational requirements. Generally, the liquid level in carbon dioxide tanks is typically maintained between 80% and 95%. There are several reasons for keeping the tank level within this range: - Space Reserve: Maintaining a certain liquid level provides steam space inside the tank, preventing overpressure and the risk of tank explosion. - Storage Capacity: Keeping a higher level maximizes the tank's capacity, allowing for more carbon dioxide storage. - Stable Supply: Maintaining an appropriate level ensures a stable supply of carbon dioxide to meet operational needs. However, specific level requirements may vary depending on different applications and industries. When using carbon dioxide tanks, follow the manufacturer's recommendations and relevant regulations and standards to ensure the tank's liquid level is controlled within a safe and suitable range.

Daily inspections and maintenance of CO2 storage tanks can be carried out in the following steps: 1. Visual Inspection: Check for any obvious damage, corrosion, or oil leakage on the tank's exterior. Pay attention to any anomalies in the tank shell, valves, and pipe connections. 2. Internal Inspection: If access to the interior is permitted, conduct an internal inspection. Check for corrosion, scale buildup, or blockages in the lining, valves, and pipes. 3. Valve and Pipe Inspection: Verify that the tank's inlet and outlet valves and pipe connections are functioning normally, and there are no leaks or loose fittings. Ensure valves operate smoothly and reliably. 4. Pressure Relief Device Inspection: Check if the tank's pressure relief devices (e.g., safety valves) are functioning properly. Confirm that the set pressure of the pressure relief devices meets requirements. 5. Measurement and Control System Inspection: Ensure the tank's level, pressure, and temperature measurement and control systems are operating correctly. Calibrate and test the accuracy of measuring equipment. 6. Cleaning and Draining: Regularly clean the interior of the tank to remove accumulated impurities and sediments. Also, periodically drain the tank to remove liquid and gas impurities. 7. Maintenance and Repair: Perform necessary maintenance and repair work based on inspection results. Repair damaged components, replace worn seals, etc., to ensure the tank operates normally. 8. Documentation and Reporting: Record the inspection and maintenance process, including the date of inspection, content of inspection, identified issues, and measures taken. Submit inspection reports to relevant departments or management as needed. The above are general steps for daily inspections and maintenance of CO2 storage tanks. Specific operations should be conducted according to the tank's characteristics and requirements. When conducting inspections and maintenance, follow relevant safety operating procedures and have personnel operate them.

Key features of carbon dioxide storage tanks primarily include the following aspects: - High storage density: Carbon dioxide storage tanks can compress carbon dioxide gas into a liquid state, significantly increasing storage density. Compared to gas storage, liquid carbon dioxide can store more carbon dioxide in relatively smaller tanks, saving space and costs. - Stable storage and supply: Carbon dioxide storage tanks can reliably store and supply carbon dioxide. Through the tank's design and control systems, accurate measurement and supply of carbon dioxide can be achieved, meeting various industrial and application needs. - Environmental friendly and renewable: Carbon dioxide is an environmentally friendly gas, and its increased concentration in the atmosphere can lead to warming and climate change. By storing and utilizing carbon dioxide, its emissions into the atmosphere can be reduced, contributing to environmental protection and sustainable development. - Safe and reliable: During the design and manufacturing process, carbon dioxide storage tanks typically use high-strength materials (such as carbon steel or stainless steel), offering good pressure resistance and safety. The tanks are usually equipped with safety valves, pressure gauges, level indicators, and other accessories to ensure safe operation. Additionally, carbon dioxide is a non-flammable and non-explosive gas, making it relatively safe. - Multiple application fields: Carbon dioxide storage tanks are widely used in various industries, including food and beverage, manufacturing, fire extinguishing, and gas supply. Carbon dioxide can be used as a preservative, carbonation agent for beverages, gas, and fire extinguishing agent, with broad applications and market demand. In summary, the key features of carbon dioxide storage tanks encompass high storage density, stable storage and supply, environmental friendliness, safety and reliability, and multiple application fields. This makes carbon dioxide storage tanks a crucial...
