The invention provides a nitrogen-rich flushing inerting pipeline system for a large commercial aircraft fuel tank. An environmental control system air guide opening (1) and an NACA air inlet (4) are connected into an air mixing and pressure stabilizing device (3), then connected to a filter (9) and then connected to an air separation module (10). High-temperature and high-pressure air and outside air are introduced from the environmental control system air guide opening (1) and the NACA air inlet (4) respectively, after mixing and pressure stabilizing processing is conducted on the air through the air mixing and pressure stabilizing device (3), the mixed air is split into two parts through the air separation module (10), one part of nitrogen-rich air enters the fuel tank, and the other part of oxygen-rich air is directly emitted to the external environment. The mixed air is introduced to be purified quickly, an oxygen-rich air pipe does not need to be arranged together with an exhaust pipe of a heat exchanger, pipe system layout and system parts are optimized, the weight of the system is reduced, and maintenance is facilitated. The air temperature and pressure are controlled precisely, matching is reasonable, and the nitrogen-rich flushing inerting pipeline system is safe and capable of saving energy.
