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. Nitrogen generator is a nitrogen production equipment designed and manufactured according to pressure swing adsorption technology. The nitrogen generator uses high-quality imported carbon molecular sieve (CMS) as adsorbent and adopts the pressure swing adsorption principle (PSA) at room temperature to separate air to produce high-purity nitrogen. Usually two adsorption towers are used in parallel, and the imported pneumatic valve is controlled by the imported PLC to automatically operate, alternately performing pressurized adsorption and decompression regeneration to complete the separation of nitrogen and oxygen and obtain the required high-purity nitrogen.
