The ASU Project of 1600Nm³/h cryogenic high-nitrogen cold box designed and manufactured by NUZHUO has been successfully precisely connected at the site of the global lithium battery giant, CATL. This is not only a connection of equipment, but also a deep handshake between the intelligent and highly stable gas solution and the world's top battery production line. It provides key support for the intelligent upgrade and green production of the new energy industry.
Being able to serve an industry-leading enterprise like CATL is the highest recognition of NUZHUO's comprehensive strength. CATL's consideration of production equipment has long gone beyond merely meeting functional requirements; it also focuses on the ultimate stability during long-term operation, the advanced energy consumption, and the compatibility with intelligent factories. With its profound technical accumulation in the field of deep cryogenic air separation, especially in the innovative breakthroughs in equipment intelligent control and energy conservation and consumption reduction, NUZHUO Group successfully met the customers' expectations for a "reliable partner" rather than a "single piece of equipment", laying the foundation for the cooperation between the two parties.
For continuous lithium battery production lines, the stability and flexibility of nitrogen supply are of utmost importance. Production schedules may have peaks and troughs, but the nitrogen system must be able to respond promptly and maintain stable purity and pressure. The key innovation of NUZHUO's equipment lies in： Firstly, it is a fully automatic load-adjusting intelligent control system. The system can automatically, precisely, and quickly adjust the load within the range of 50% - 105% based on the actual changes in gas consumption at the end of the production line. It can automatically adjust key parameters such as the guide vanes of the air compressor, the nozzle of the expander, and the throttle valve, while maintaining the stability of the process conditions in the distillation tower as the production volume changes, thus ensuring constant purity and pressure of the output nitrogen. This completely solves the problems of manual adjustment lag and fluctuating purity of traditional equipment, achieving "on-demand supply, stable high output"; Secondly, it features an efficient plate-fin heat exchanger and energy recovery system. The equipment uses large vacuum brazed aluminum plate-fin heat exchangers with optimized flow paths, achieving extremely high heat exchange efficiency and effectively reducing system operating energy consumption. At the same time, it innovatively optimizes the process flow path, fully utilizing the refrigeration power of the expander and the cold energy of the reflux waste nitrogen, minimizing the heat loss of the entire cold box and achieving efficient and hierarchical utilization of energy; Finally, it includes redundant design and fault warning. Key pumps and valves are designed with backup systems, and the control system is equipped with a complete fault self-diagnosis and safety interlock protection system. If parameters deviate from the preset range, the system will issue an early warning or automatically switch to a safe mode, minimizing unplanned downtime and ensuring the continuous operation of the production line 7x24 hours.
The collaboration between NUZHUO and CATL has brought more than just the value of the equipment to the lithium battery industry. What it offers is not merely a nitrogen generation device, but a complete intelligent and flexible gas supply management solution. This perfectly meets the demand for intelligent manufacturing upgrade in lithium battery factories, enhancing the automation and response speed of the entire production system. At the same time, its remarkable energy-saving effect directly reduces the production energy consumption and carbon footprint of CATL, embodying the concept of green manufacturing.
