The working principle of nitrogen generator

Nitrogen generator refers to a device that uses air as raw material and uses physical methods to separate oxygen and nitrogen in it to obtain nitrogen. Nitrogen generators used in industry can be divided into three types according to different classification methods, namely cryogenic air separation, molecular sieve air separation (PSA) and membrane air separation.Aluminum extrusion die vacuum heat treatment The principle of nitrogen production by cryogenic air separation Cryogenic nitrogen production can not only produce nitrogen but also liquid nitrogen, which meets the process requirements of liquid nitrogen, and can be stored in liquid nitrogen storage tanks. After entering the vaporizer and being heated, it is fed into the product nitrogen pipeline to meet the nitrogen demand of the process unit. Vacuum Heat Treatment Process of Rolling BearingsThe operation cycle of cryogenic nitrogen production (referring to the interval between two large heatings) is generally more than 1 year. Therefore, cryogenic nitrogen production is generally not considered for backup. The pressure swing adsorption nitrogen production can only produce nitrogen, there is no backup means, and a single set of equipment cannot guarantee continuous long-term operation.Vacuum brazing process of electrical contact brazing rate
