Nitrogen making machine is widely used in all walks of life, for different industries, different users of nitrogen use of different requirements, you can choose different types of equipment to use. Cryogenic airseparation nitrogen equipment for large-scale industrial production of nitrogen, while the middle and small scale nitrogen is not economic, cryogenic airseparation nitrogen nitrogen is a traditional method, has decades of history. The utility model is characterized in that the air is used as raw material to be compressed and purified, and then the heat exchange is used to liquefy the air into liquid air.
The membrane air separation nitrogen making equipment uses air as the raw material, under certain pressure condition, uses the oxygen and the nitrogen and so on the different nature gas to have the different infiltration rate in the membrane to cause the oxygen and the nitrogen separation. It has many advantages such as simpler structure, smaller volume, no switching valve, less maintenance, faster gas production, and more convenient to produce.
