The 100 cubic meter large-flow industrial nitrogen generator system is a high-capacity nitrogen supply solution designed for large-scale industrial production scenarios such as chemical production, metallurgical processing, pharmaceutical manufacturing and new energy materials. This system takes stable large-flow continuous nitrogen production, high nitrogen purity accuracy and low energy consumption operation as the core design goals, and adopts a combined optimized configuration of PSA pressure swing adsorption technology and high-efficiency air pretreatment system, which can stably output 100m³/h standard nitrogen flow for 24 hours without interruption. The system can realize stepless adjustment of nitrogen purity between 93%–99.999%, meeting the differentiated nitrogen use requirements of different production processes in large industrial enterprises.

The overall system solution consists of four core subsystems: air compression system, air purification pretreatment system, PSA nitrogen separation main system and nitrogen storage and pressure stabilization system. The air compression system is matched with energy-saving screw air compressors to provide stable compressed air source for the whole system; the pretreatment system includes high-efficiency cold dryers, precision filters and oil-water separation devices, which thoroughly remove moisture, oil and impurities in compressed air to ensure the service life of subsequent adsorption equipment and nitrogen product purity. The core PSA nitrogen production unit adopts high-quality carbon molecular sieve with high adsorption efficiency and strong anti-aging performance, and optimizes the tower body structure and gas circuit design to improve the nitrogen separation efficiency, ensuring that the large-flow output state still maintains high nitrogen yield and low energy consumption.

The system is equipped with an intelligent centralized control platform, which can realize automatic startup and shutdown, parameter self-adjustment, real-time data monitoring and fault self-diagnosis functions. The remote monitoring module supports enterprise personnel to view operating data and adjust operating parameters in real time, realizing unattended operation of the equipment. In terms of safety and energy-saving design, the system is equipped with multiple protection devices such as overpressure protection, pressure relief protection and power failure self-locking, and optimizes the gas circulation process to reduce invalid energy consumption. Compared with multiple small-flow nitrogen generators in parallel, the integrated 100m³/h large-flow system has lower unit nitrogen production energy consumption, smaller floor area and simpler later maintenance, which can effectively reduce the overall operating cost of enterprise nitrogen supply and is suitable for large-scale industrial continuous production scenarios with stable nitrogen demand.
