Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically a high-purity nitrogen generator with waste gas treatment function. Background Technology

[0002] In industrial production, nitrogen, as an important inert gas, is widely used in many fields such as food packaging, chemical production, and electronics manufacturing. In order to meet the strict requirements of different industries for nitrogen purity, high-purity nitrogen generators have emerged. These devices extract high-purity nitrogen from the air through a series of precise separation and purification processes. However, in the process of producing high-purity nitrogen, a certain amount of waste gas is often generated. If this waste gas is discharged directly into the environment without treatment, it will not only waste resources but may also pollute the ecological environment.

[0003] Traditional high-purity nitrogen generators often use an integrated design for their exhaust gas treatment components. If a component fails, the entire component needs to be replaced, increasing maintenance costs and operational complexity. In addition, the connection between the exhaust gas treatment device and the nitrogen generator is often fixed, making it inconvenient for equipment maintenance and replacement. Therefore, we provide a high-purity nitrogen generator with exhaust gas treatment capabilities for use. Utility Model Content
