Kev tsim cov hlau xav tau cov pa oxygen raws li cov txheej txheem roj rau kev txhim kho combustion, molten hlau kho, thiab cov tshuaj tiv thaiv oxidation. Cov pa oxygen yuav tsum ua kom haum rau kev ua haujlwm ntawm cov nroj tsuag steel, nrog rau hom rauv, cov pa oxygen noj, xav tau purity, muab siab, thiab cov sijhawm tsim khoom.
Rau me me thiab nruab nrab xav tau oxygen,PSA(Pressure Swing Adsorption) oxygen generators tuaj yeem tsim cov pa oxygen ncaj qha los ntawm huab cua compressed los ntawm molecular sieve adsorption. Rau cov nroj tsuag loj dua uas xav tau cov pa oxygen tas mus li ntawm ntau pua lossis ntau txhiab Nm³ / h, VPSA (Nqus Siab Swing Adsorption) cov tshuab feem ntau raug txiav txim siab vim tias cov txheej txheem sib cais siv lub tshuab nqus tsev rov ua dua tshiab thiab lub tshuab cua tshuab cua tshuab. Kev xaiv ntawm PSA thiab VPSA nyob ntawm qhov xav tau oxygen, kev siv lub zog, kev teeb tsa, thiab kev koom ua ke nrog cov khoom siv hlau.
Hauv kev tsim cov hlau, cov pa oxygen tsis yog ib qho khoom siv roj. Nws yog ib feem ntawm cov txheej txheem ntau lawm. Lub tshuab pa oxygen yuav tsum txuas nrog rau lub tshuab hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob, lub tshuab hluav taws xob sib txuas, lossis cov cuab yeej ua kom zoo dua qub thaum tswj kev ruaj khov thiab siab thaum lub sijhawm ua haujlwm tas mus li.
PSA Oxygen Generation Technology ua haujlwm li cas?
PSA oxygengenerators cais oxygen los ntawm compressed cua los ntawm ib tug rov adsorption thiab regeneration txheej txheem. Lub hauv paus ntsiab lus ntawm lub cev yog lub adsorption ntauwd uas muaj zeolite molecular sieve, uas muaj cov yam ntxwv sib txawv adsorption rau nitrogen thiab oxygen molecules.
Ib qho PSA oxygen tiam system muaj ntau yam tseem ceeb:
| Cheebtsam | Muaj nuj nqi |
|---|---|
| Cua Compressor | Muab compressed cua rau txoj kev sib cais |
| Kev kho cua tshuab | Tshem tawm cov roj, noo noo, thiab impurities los ntawm compressed cua |
