Product Description Product ParametersPSA pressure swing adsorption nitrogen production equipment:1. PSA pressure swing adsorption nitrogen production principle:Under a certain pressure, carbon molecular sieve adsorbent is used to separate high air by taking advantage of the different diffusion rates of oxygen and nitrogen in the air in the pores of carbon molecular sieve. That is, the diffusion adsorption of oxygen on carbon molecular sieve is far greater than that on helium, so the oxygen in the air (carbon dioxide, water vapor, etc.) is first adsorbed; Nitrogen is enriched through the adsorption bed and exported as product gas. When the components adsorbed by the adsorbent in the tower tend to be saturated, the atmospheric desorption is carried out to regenerate the adsorbent: the clean compressed air after the pretreatment of oil removal, water removal and dust removal enters another adsorption tower to continue to adsorb and produce nitrogen. The programmable controller PLC controls the opening and closing of each valve in the pipeline system, pressurized adsorption, and depressurized desorption to achieve the alternate cycle of the two adsorption towers to complete the connection and nitrogen production. This process is PSA pressure swing adsorption nitrogen generation.
