Pressure swing adsorption nitrogen equipment introduction

Equipment for liquid nitrogen in Hangzhou poly air separation equipment manufacturing Co Ltd is based on the production of pressure swing adsorption principle, using carbon molecular sieve as absorbent quality, under pressure from the air, nitrogen. After cleaning and drying compressed air, pressure adsorption, vacuum desorption in the adsorber. The dynamic effect, oxygen in carbon molecular sieve is far greater than the rate of nitrogen diffusion in micropores, the adsorption is not balance, nitrogen in the gas phase by enrichment, nitrogen form product. Then decompression to atmospheric pressure, adsorbent by adsorption desorption of oxygen and other impurities, realize regeneration. General settings in the system of two adsorption towers, one tower of nitrogen adsorption capacity, the other tower of regeneration, through the PLC program automatic control, so that the two towers cycle. After finished the nitrogen output liquid nitrogen Stirling cryocooler.

The machine has the advantages of simple process flow, normal production, high degree of automation, open stop convenient, less wearing parts, convenient maintenance and low production cost.
