Nws ua haujlwm li cas
Pressure Swing Adsorption yog cov pa roj- cov txheej txheem sib cais uas siv cov khoom siv adsorption xaiv kom tshem tawm nitrogen los ntawm huab cua compressed, tawm hauv cov pa oxygen raws li cov khoom kawg.
Txoj Cai Ua Haujlwm Core
PSA systems cia siab rauzeolite molecular sieves, uas muaj affinity siab rau nitrogen molecules. Cov txheej txheem feem ntau ua raws li ob -ntauwd adsorption voj voog:
Cua Compression & Ua ntej- Lim
Cov huab cua nyob ib puag ncig raug pom kom tshem tawm cov plua plav, roj vapor, thiab noo noo ua ntej nkag mus rau PSA chav tsev.
Adsorption Phase
Compressed cua ntws mus rau hauv ib tug adsorption ntauwd uas zeolite ntxiab nitrogen. Oxygen dhau los ua cov khoom siv roj.
Desorption (Regeneration) Phase
Lub pej thuam depressurizes, tso cov khoom ntim nitrogen thiab tso cai rau zeolite rov tsim dua.
Lub voj voog hloov
Thaum ib tug pej thuam adsorbs, lwm tus regenerates. Lub kaw lus alternates ntawm lawv tsis tu ncua.
Qhov no cycling tsim ibruaj khov oxygen tso zis, feem ntau nyob rau hauv qhov ntau ntawm93% ± 3% purity, uas tau txais los ntawm cov koom haum kho mob loj thoob ntiaj teb.
