[0002] Nitrogen generator is an advanced gas separation technology. It uses high-quality imported carbon molecular sieve (CMS) as adsorbent and adopts the principle of pressure swing adsorption at room temperature to separate air and produce high-purity nitrogen. Nitrogen is widely distributed in nature and is the main component of air. It is colorless, odorless, non-toxic, non-flammable and non-explosive at room temperature. It is very safe to use, and its molecular structure is very stable and its chemical properties are very inactive. It is usually difficult to react chemically with other substances and exhibits great inertness. It is widely used as a protective gas. Nitrogen generator is a commonly used nitrogen production device. It has the characteristics of high safety, strong adaptability and continuous production.

[0003] However, in the existing equipment, since the air compressor in the nitrogen generator is fixed to the box by bolts and has no buffering noise reduction structure, it will generate large noise during the operation of the equipment, causing noise pollution to the surrounding environment. For this reason, a high-throughput nitrogen generator with adjustable purity is proposed. Utility Model Content
