Description

Technical Field

[0002] Nitrogen generator is an advanced gas separation technology. It uses high-quality imported carbon molecular sieve (CMS) as adsorbent and pressure swing adsorption (PSA) principle at room temperature to separate air to produce high-purity nitrogen. During the use of the current nitrogen generator, air is generally passed into the nitrogen generator, and then the oxygen is absorbed by the nitrogen generator. Finally, the purified nitrogen is discharged from the nitrogen generator for collection. In the nitrogen preparation process, a nitrogen generator is required. However, during the use of the current nitrogen generator, the filter used to filter impurities in the incoming air is not easy to disassemble and clean, which makes the subsequent filtering effect of the nitrogen generator on the air poor. Therefore, we propose an automatic purification high-purity nitrogen generator to solve the above problems. Utility Model Content
