Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a nitrogen generator with a noise reduction function. Background Art

[0002] Nitrogen is a colorless and odorless gas. It is one of the main components of air. It accounts for 78.08% of the total atmosphere and has a lower density than air. Nitrogen is often called an inert gas. It is used in some inert gases for metal processing and in light bulbs to prevent arcing, but it is not chemically inert. It is an essential element in plant and animal life and a component of many useful compounds. Nitrogen combines with many metals to form hard nitrides, which can be used as wear-resistant metals. A small amount of nitrogen in steel will inhibit grain growth at high temperatures and also increase the strength of some steels. Therefore, nitrogen is widely used in all walks of life. Nitrogen generators are commonly used to manufacture nitrogen equipment. Nitrogen generators are a type of nitrogen generating equipment. It uses air as raw material, high-quality carbon molecular sieves as adsorbents, and uses the principle of pressure swing adsorption. It uses a molecular sieve full of micropores to selectively adsorb air to achieve the purpose of oxygen and nitrogen separation to produce nitrogen.

[0003] In the existing technology, most nitrogen generators generate relatively loud noise during use. Long-term exposure to high-noise environments may cause employees to suffer from health problems such as hearing loss, anxiety and sleep disorders, which will have a negative impact on their physical and mental health.
