AI Technical Summary

Technical Problem

During the nitrogen separation process, existing nitrogen generators fail to effectively utilize unqualified nitrogen resources, resulting in waste of nitrogen resources and increased air treatment, thereby increasing energy loss.

Method used

An energy-saving nitrogen generator with a closed-loop structure was designed to initially store the nitrogen gas generated by the nitrogen-oxygen separation mechanism through a nitrogen buffer tank, and pass and fail nitrogen gas is detected by a nitrogen detection mechanism. Qualified nitrogen is enriched in the nitrogen storage tank, while unqualified nitrogen is pumped to the inlet of the nitrogen-oxygen separation mechanism through booster pumping to reseal the resource recycling.

Benefits of technology

It effectively avoids the waste of nitrogen resources, reduces the amount of air processing and energy loss, and improves the energy-saving effect of the nitrogen generator.

Abstract

The utility model discloses an energy-saving nitrogen making machine with a closed-loop structure, which comprises an air compressor, an air storage tank, an oxygen-nitrogen separation mechanism and a nitrogen buffer tank which are connected in sequence, a nitrogen detection mechanism is mounted at an air outlet of the nitrogen buffer tank, and the nitrogen detection mechanism is provided with a first air outlet and a second air outlet; the first gas outlet is communicated with the nitrogen storage tank through a pipeline, and a first valve is arranged on the pipeline between the first gas outlet and the nitrogen storage tank; the second gas outlet is communicated with the gas inlet of the nitrogen-oxygen separation mechanism through a pipeline, and a second valve and a booster pump are sequentially arranged on the pipeline of the second gas outlet and the nitrogen-oxygen separation mechanism. Nitrogen generated by the nitrogen-oxygen separation mechanism is preliminarily stored through the nitrogen buffer tank, qualified nitrogen detected by the nitrogen detection mechanism is enriched in the nitrogen storage tank, and unqualified nitrogen is conveyed to an air inlet of the nitrogen-oxygen separation mechanism through the booster pump to be separated again, so that waste of nitrogen resources is avoided, the air handling capacity is reduced, and the nitrogen-oxygen separation efficiency is improved. And the energy loss is reduced.
