Nitrogen molecules muaj qhov sib txawv sai dua nyob rau hauv micropores ntawm zeolite molecular sieve, thiab cov pa oxygen molecules muaj qhov qeeb qeeb.Qhov sib txawv ntawm cov dej thiab carbon dioxide nyob rau hauv compressed cua yog zoo ib yam li cov nitrogen.Thaum kawg, oxygen molecules yog enriched los ntawm lub adsorption ntauwd.Siab viav vias adsorption oxygen ntau lawm siv cov kev xaiv adsorption yam ntxwv ntawm zeolite molecular sieve, txais yuav lub voj voog ntawm kev siv zog adsorption thiab decompression desorption, thiab ua rau cov cua compressed nkag mus rau hauv lub adsorption ntauwd hloov kom paub txog kev sib cais ntawm oxygen thiab nitrogen, thiaj li ua kom tsis tu ncua ua kom siab. - purity thiab high-zoo oxygen.
PSA oxygen generator txais cov zoo zeolite ua adsorbent raws li lub hauv paus ntsiab lus ntawm siab viav vias adsorption.Nyob rau hauv ib lub siab, oxygen yog muab rho tawm los ntawm huab cua, purified thiab qhuav compressed cua, thiab pressurized adsorption thiab decompression desorption yog nqa tawm nyob rau hauv lub adsorption.Vim cov nyhuv aerodynamic, qhov diffusion tus nqi ntawm nitrogen hauv micropores ntawm zeolite molecular sieve yog ntau dua li cov pa oxygen.Nitrogen yog qhov zoo tshaj plaws adsorbed los ntawm zeolite molecular sieve, thiab oxygen yog enriched nyob rau hauv cov roj theem los tsim cov pa tiav lawm.Tom qab ntawd, tom qab decompression rau atmospheric siab, molecular sieve desorbs lub adsorbed nitrogen thiab lwm yam impurities kom paub regeneration.Feem ntau, ob lub adsorption yees yog teem rau hauv lub cev, ib qho rau adsorption thiab oxygen ntau lawm, thiab lwm yam rau desorption thiab regeneration.PLC tswj qhov kev pab cuam tswj qhov qhib thiab kaw ntawm lub pneumatic valve kom ob lub yees sib hloov, thiaj li ua tiav lub hom phiaj ntawm kev tsim cov pa oxygen zoo.
