Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen generators, in particular to a four-tower multi-mode nitrogen generator. Background Art

[0002] Nitrogen generators are mainly used in technical fields such as oil extraction, coal chemical industry, salt chemical industry, and natural gas chemical industry. The working principle of nitrogen generators is to use air as raw material to separate oxygen and nitrogen in it to obtain nitrogen. Four-tower multi-mode nitrogen generators are commonly used nitrogen making equipment in industry. Existing four-tower multi-mode nitrogen generators usually use filter components to filter the air entering the four-tower multi-mode nitrogen generators. After the filter components have been used for a period of time, dust in the air will accumulate on the filter components, affecting the filtering effect. Therefore, a four-tower multi-mode nitrogen generator is proposed to facilitate dust cleaning. Utility Model Content
