The nitrogen pipe network comprises a third-stage pipe network and a second-stage pipe network, a third-stage high-pressure pipeline is fixedly connected to the right side of the third-stage pipe network, a second-stage high-pressure pipeline is fixedly connected to the left side of the second-stage pipe network, and a third-stage high-pressure pipeline is fixedly connected to the right side of the second-stage pipe network. A third-stage high-pressure pipeline and a second-stage high-pressure pipeline are used for connecting a third-stage pipe network with a second-stage pipe network, a pressure reducing valve is used at the joint, high-pressure nitrogen of the third-stage pipe network is fed into the second-stage pipe network for use after being depressurized by the pressure reducing valve, and the third-stage pipe network and the second-stage pipe network are reasonably connected in series, so that low-energy-consumption resources are reasonably utilized; the energy-saving nitrogenmaking device is novel in
