The energy-saving nitrogen making machine of high pressure uses an all-in-one system, that is, built-in oil-free compressor. Firstly, freezing and drying machine and three-stage filter are used to remove grease, dust particles. After preprocessed, the oil-free dry air is pushed into two groups of nitrogen adsorb machines to separate hydrogen and nitrogen. While one group adsorbing, the other group stripping, continuous qualified nitrogen is produced to nitrogen buffer tank. When nitrogen buffer tank's pressure reaches to set value, nitrogen generating unit stops and instead pressurization system starts charging nitrogen. When the nitrogen gas buffer tank pressure drops to the set point, it is supposed to stop charging and begin the operation of nitrogen making, thereby continuously outputting high pressure nitrogen whose pressure can be up to 1. 5 Mpa - 30 Mpa.

Running state of the machine is "automatic operation" (that is, without the need for operating the start-stop of the equipment). Air inlet and nitrogen outlet are equipped with pressure regulating components, the built-in refrigeration dryer and C, T, A three-stage filter and automatic drainage device. Siemens host is used in PC control system. Nitrogen purity is monitored by analyzer on-line, by 99.99-99.999% unit. Automatic emptying and alarm are set if the purity of nitrogen is unqualified, and the system will automatically stop when it reaches the set pressure after qualified nitrogen output, thus, saving the air compressor power consumption by up to 10-30% range. Altemately emptying system of nitrogen adsorption tower, with a rapid emptying device, in order to achieve rapid stripping requirements in nitrogen making process, prolongs the life of electromagnetic valve.
