Embodiment 1
[0020] In a two-tower VPSA air separation oxygen-enriched system, taking the tower group consisting of TA1 and TB1 as an example, the process flow is described as follows:
[0021] (1) Adsorption (A): Open the valves VA1, VA3, VA6, V7, and the air enters the tower TA1 from the bottom of the tower. In the tower TA1, H in the air 2 O, CO 2 It is adsorbed and removed by activated alumina and 13X molecular sieve in turn. Then through valve VA3, enter TB1 from the bottom. In tower TB1, N2 is adsorbed and removed by molecular sieve for oxygen-nitrogen separation. The oxygen-enriched product gas is sent to product gas buffer tank V through valves VA6 and V7, when the front of adsorbing impurities When reaching a specific position in the reserved section of the outlet of the adsorption bed, close the valves VA1, V7, and VA3 to stop the adsorption.
[0022] (2) The upper and lower towers of the tower group are equalized and reduced in parallel (TAED, TBED): Open valves VB6, VA5, close valve...
