QP-300Q nitrogen generator

The latest developed hollow fiber membrane nitrogen generator by Shanghai Gas Spectral Instrument Co., Ltd. is an instrument that uses high-pressure air to separate and produce high-purity nitrogen gas in a high-precision hollow fiber membrane separation column.



In the hollow fiber membrane separation column, the permeability of nitrogen and oxygen molecules in the dense space composed of fibrous membrane materials is different. When high-pressure air passes through the membrane material, a nitrogen concentration difference is formed on the inlet and outlet sides. The accumulation of multiple membrane materials in the membrane separation column amplifies this concentration difference, and nitrogen is separated from other gases in the air at the inlet and outlet ends of the membrane separation column. The air passes through the membrane separation column to obtain high-purity nitrogen.



The conditions that affect the separation efficiency of hollow fiber membrane separation columns are as follows:
The strength of membrane materials refers to their support;
Density distribution of pores in membrane materials;
The quality of air at the intake end. The nitrogen generator produced by our company adopts a membrane separation column imported from the United States, with uniform pore size distribution and high separation efficiency. At the same time, the membrane material has good support, high strength, and strong pollution resistance. The air part adopts high-quality high-precision filters to remove 99.9% of liquid water and>0.01um dust, making the air entering the membrane separation column oil-free, waterless, and dust-free, greatly improving the stability of the whole machine. It can be maintained for 5 years and the instrument has a lifespan of more than 10 years.
