PSA nitrogen generator uses compressed air as the raw material, which makes use of the adsorption characteristics of molecular sieve used in nitrogen production equipment to separate oxygen and enrich nitrogen to obtain high purity nitrogen. Nitrogen is a kind of protective inert gas, which is widely used in food, chemical, pharmaceutical, metallurgy, electronics, solar energy and other industries. Nitrogen accounts for 79% of the air. Compared with the inert gas of nitrogen generator, it is easy to extract and has low cost.
Alias: photovoltaic nitrogen machine, also known as nitrogen machine, nitrogen machine, nitrogen generator, nitrogen filling machine.
Principle: the oil-free air compressor provides 0.8 MPa compressed air pressure swing adsorption raw material for nitrogen production. After being treated by freeze dryer and filter, clean compressed air without water, oil and dust is obtained. It enters the adsorption tower filled with molecular sieve. Oxygen molecule is less than nitrogen molecule, oxygen molecule enters porous molecular sieve first, and nitrogen enters nitrogen storage tank quickly through molecular sieve layer. A set of nitrogen generator is equipped with two adsorption towers, which work alternately to realize continuous extraction of nitrogen.
