I-VPSA PSA vacuum analytical oxygen plant
Imishini yokukhiqiza umoya-mpilo ye-VPSA PSA
I-VPSA uhlobo lwe-PSA imishini yokukhiqiza umoya-mpilo yokuhlaziya i-vacuum ithatha i-PSA kanye nokuhlaziywa kwe-vacuum njengomgomo, isebenzisa isisefo se-calcium / i-lithium yamangqamuzana ephezulu njenge-adsorbent, futhi ithola umoya-mpilo ngokuqondile emkhathini.
EzobuchwephesheIabafundisi
Isikali somkhiqizo: 100-10000n ㎥ / h
Ukuhlanzeka komoyampilo: ≥ 70-94%
Umfutho we-oxygen: ≤ 20KPa (owubiza kakhulu)
Izinga lokusebenza ngonyaka: ≥ 95%
Wisimiso se-orking
Imishini yokukhiqiza i-VPSA vacuum desorption oxygen yakhiwa ikakhulukazi i-blower, i-vacuum futha, i-switch valve, i-adsorber ne-oxygen balance tank.Umoya oluhlaza ucindezelwa yi-root blower ku-adsorber egcwele isisefo se-oxygen molecular, lapho amanzi, i-carbon dioxide ne-nitrogen kufakwa khona ukuze kukhiqizwe umoya-mpilo.Lapho i-adsorption ifinyelela izinga elithile, ipompo ye-vacuum isetshenziselwa ukuvala amanzi adsorbed, i-carbon dioxide, i-nitrogen kanye nenani elincane lamanye amaqembu egesi ngokulandelanayo likhishwa likhishwe emkhathini, bese i-adsorbent ivuselelwa.Izinyathelo zenqubo ezingenhla zilawulwa ngokuzenzakalelayo yi-PLC kanye nesistimu ye-valve yokushintsha.

Inkambu yohlelo lokusebenza nokuqhathanisa nendlela ye-cryogenic
Umsebenzi wokuphephetha komoyampilo esithandweni somlilo esivulekile ukusekela ukuvutha.Inhloso yawo ukuqinisa inqubo yokuncibilikisa, ukunciphisa isikhathi sokuncibilikisa nokwandisa ukuphuma kwensimbi kwesithando somlilo esivulekile.Kufakazelwe ukuthi ukuvunguza komoya-mpilo esithandweni somlilo esivulekile kungakhuphula ukukhiqizwa kwensimbi isikhathi esingaphezu kwesisodwa futhi kunciphise ukusetshenziswa kukaphethiloli ngo-33% ~ 50%.
I-oksijeni esetshenziswa esithandweni sikagesi ingasheshisa ukuncibilika kokushaja kwesithando somlilo kanye ne-oxidation yokungcola, okusho ukuthi ukuvunguza komoya-mpilo esithandweni sikagesi akukwazi nje ukuthuthukisa umthamo wokukhiqiza kodwa futhi kuthuthukise ikhwalithi ekhethekile.Ukusetshenziswa kwe-oksijini ngethoni ngayinye yensimbi yesithando somlilo kagesi kuyahlukahluka kuye ngezinhlobo ezahlukene zensimbi okufanele zincibilikiswe, isibonelo, ukusetshenziswa kwe-oksijini ngethani lensimbi ye-carbon structural yi-20-25m3, kanti leyo yensimbi ephezulu ye-alloy ingu-25-30m3.I-oxygen edingekayo ihlanganisa 90% ~ 94%.
Ukuqhuma kwe-oxygen esithandweni somlilo kunganciphisa kakhulu ukupheka futhi kukhulise ukukhiqizwa.Ngokwezibalo, lapho ukuhlushwa komoyampilo kukhuphuka ngo-1%, ukuphuma kwensimbi kunganyuswa ngo-4% - 6%, futhi ukupheka kungancishiswa ngo-5% - 6%.Ikakhulukazi lapho insimbi esekelwe ngamalahle eyenza izinga lomjovo wamanzi lifinyelela ku-300kg, inani le-oxygen elihambisanayo lingu-300m3 / iron.
Lapho umoya-mpilo wethulwa ohlelweni lokuncibilika kwezinsimbi ezingenayo insimbi, isibabule singashiswa ngokugcwele, izinga lokushisa lokuncibilika lingagcinwa futhi isivinini sokuncibilika singandiswa.Ukuthatha ithusi njengesibonelo, ukuncibilikisa ithusi okuthuthukisiwe komoyampilo kungasindisa amandla angama-50%, okungukuthi, ngaphansi kokusetshenziswa okufanayo kukaphethiloli, ukuphuma kwethusi kungaphinda kabili.
