The principle and characteristics of PSA N2 nitrogen generator

Haoyong Technology's nitrogen generator uses PSA (Pressure Swing Adsorption) Nitrogen Gas regeneration (also known as pressure swing adsorption) to produce nitrogen. It is used at normal temperature to apply each gas molecule under high pressure due to the different adsorption speeds of molecular sieve carbon (Carbon Molecular Sieves). Different characteristics and the development of equipment to generate nitrogen.

The molecular size of nitrogen is about 4.3 X 3.0 A, and the molecular size of oxygen is about 3.9 X 2.8 A. The pore size of molecular sieve carbon (CMS) is uniformly controlled at 4.0 A. When high-pressure compressed air is fed into the adsorption tower filled with molecular sieve carbon, because Oxygen molecules are smaller than nitrogen molecules, so a large amount of oxygen and a small amount of water vapor will be adsorbed by molecular sieve carbon in a short period of time.

On the other hand, gases such as oxygen adsorbed by molecular sieve carbon under pressure can be easily discharged through the desorption function of decompression discharge, and two adsorption towers are used for continuous switching operation to continuously separate nitrogen from the air. .
