I-VPSA Oxygen Generator

Imishini yokukhiqiza oksijini ye-Psa, ngaphansi kwesimo segumbi lokushisa nengcindezi yasemkhathini, ISEBENZISA ngesihlungo esikhethekile samangqamuzana e-VPSA ukumunca ngokukhetha initrogen, isikhutha kanye namanzi nokunye ukungcola emoyeni, ukuze kutholakale umoya-mpilo ngokuhlanzeka okuphezulu (93 ± 2% ).

Ukukhiqizwa kwendabuko komoya-mpilo ngokuvamile kwamukela indlela yokuhlukanisa i-cryogenic, engaveza umoya-mpilo ngokuhlanzeka okuphezulu. Kodwa-ke, imishini inokutshalwa kwezimali okuphezulu, futhi imishini isebenza ngaphansi kwesimo sengcindezi ephezulu kanye nezinga lokushisa eliphansi kakhulu. Ukusebenza kunzima, izinga lokulungisa liphezulu, futhi ukusetshenziswa kwamandla kuphezulu, futhi kuvame ukudlula emahoreni amaningi ukukhiqiza igesi ngemuva kokuqala.

Njengoba imishini yokukhiqiza umoya-mpilo i-psa ingene kwezimboni, ubuchwepheshe sebuthuthuke ngokushesha, ngoba ukusebenza kwentengo yayo kunebanga lesivuno esiphansi kanye nezidingo zobumsulwa aziphezulu kakhulu esimweni kunokuncintisana okuqinile, ngakho-ke kusetshenziswa kakhulu ukuncibilikisa, ukuqhuma kwesithando somlilo oksijini, ukugcotshwa kwamathambo, isithando sengilazi, ukwelashwa kwamanzi angcolile kanye neminye imikhakha.

Ucwaningo lwasekhaya ngalobu buchwepheshe luqale ekuqaleni, kepha esikhathini eside intuthuko ihamba kancane.

Kusukela ngama-1990s, izinzuzo zemishini yokukhiqiza umoya-mpilo ye-psa ziye zabonwa kancane kancane ngabantu baseChina, futhi eminyakeni yamuva nje, izinqubo ezahlukahlukene zemishini zifakiwe ekukhiqizeni.

Imishini yokukhiqiza i-psa VPSA oxygen yeHangzhou Boxiang Gas Equipment Co., Ltd. inesikhundla esiphambili emkhakheni wemboni kamanyolo, futhi umphumela wayo uphawuleka kakhulu.

Enye yezinkomba eziphambili zentuthuko ye-psa ukunciphisa inani le-adsorbent nokwenza ngcono amandla wokukhiqiza wemishini. Kodwa-ke, ukwenziwa ngcono kwama-sieve wamangqamuzana wokukhiqizwa komoya-mpilo kuhlala kwenziwa endaweni yezinga eliphakeme le-nitrogen adsorption, ngoba ukusebenza kwe-adsorption kwama-sieve wamangqamuzana kuyisisekelo se-PSA.

I-sieve yamangqamuzana enekhwalithi enhle kufanele ibe ne-coefficient yokuhlukanisa i-nitrogen ne-oxygen ephezulu, amandla okugcwala kwe-adsorption namandla aphezulu.

I-PSA enye inkomba enkulu yokuthuthuka ukusebenzisa umjikelezo omfushane, ayidingi kuphela ikhwalithi eqinisekisiwe yesihlungo samangqamuzana, ngasikhathi sinye kufanele isuselwe ekusebenzeni kahle kwesakhiwo sangaphakathi se-adsorption, ukugwema okungadala ukuthi umkhiqizo ube mubi futhi ukungalungi kokusatshalaliswa okungafaniyo kokuhlungwa kwegesi embhoshongweni we-adsorption, kanye nokubeka phambili izidingo eziphakeme zokushintsha kweveluvane.

Ezinqubo eziningi zokukhiqiza umoya-mpilo ze-PSA, i-PSA, i-VSA ne-VPSA ingahle ihlukaniswe ngezinhlobo ezintathu.

I-PSA yinkqubo enkulu yokukhishwa kwengcindezi enkulu yokukhipha umoya. Inezinzuzo zophiko olulula nezidingo eziphansi zama-sieve wamangqamuzana, nobubi bokusetshenziswa kwamandla okuphezulu, okufanele kusetshenziswe kwimishini emincane.

I-VSA, noma inqubo yokucindezela ukukhishwa kwe-vacorption ye-atmospheric, inenzuzo yokusebenzisa amandla aphansi kanye nokungahambi kahle kwemishini eyinkimbinkimbi nokutshalwa kwezimali okuphelele.

I-VPSA inqubo yokukhipha i-vacuum ngokusebenzisa ingcindezi yasemkhathini. Inezinzuzo zokusetshenziswa kwamandla aphansi nokusebenza kahle kwesisefo samangqamuzana. Ukutshalwa kwemali okuphelele kwemishini kuncane kakhulu kunalokho kwenqubo ye-VSA, futhi ukungalungi kuyizidingo eziphakeme kakhulu zesisefo se-molecular ne-valve.

Igesi leHangzhou Boxiang lamukela inqubo ye-VPSA, futhi lenza intuthuko enkulu kunqubo yendabuko nenqubo, enganciphisi ukusetshenziswa kwamandla kuphela (ibhekisa ekusetshenzisweni kwesihlungo se-molecular efanayo), kodwa futhi ifinyelela umgomo wokwenza lula nokwenza izinto zibe lula Okokusebenza, kunciphisa utshalomali, futhi kunesilinganiso sokusebenza / sentengo esiphakeme.

Lonke uhlelo lokukhiqiza i-psa oxygen lubunjwe nge-blower, iphampu ye-vacuum, i-valve eshintshayo, i-absorber ne-oxygen pressure booster unit ye-oxygen balance tank.

Ngemuva kokuthi izinhlayiya zothuli zisuswe ngesihlungi sokumunca, umoya ongahluziwe uyacindezelwa uye ku-0.3 ~ 0.4 Barg by Roots blower bese ungena kwesinye se-adsorbents.

I-adsorbent igcwaliswe ku-adsorbent, lapho amanzi, isikhutha, nenani elincane lezinye izinto zegesi zikhangiswa ethekwini le-adsorbent yi-alumina eyenziwe isebenze ngezansi, bese kuthi i-nitrogen ikhonjiswe yi-alumina ne-zeolite eyenziwe yasebenza. ngaphezulu kwesihlungo se-13X yamangqamuzana.

I-oksijeni (kufaka phakathi i-argon) yingxenye engeyona i-adsorbed futhi ikhishwa kusuka endaweni ephezulu ye-adsorber iye ethangini le-oxygen balance njengomkhiqizo.

Lapho i-adsorbent ikhangiswe ngezinga elithile, i-adsorbent izofinyelela esimweni sokugcwala. Ngalesi sikhathi, ipompo yokupaka izosetshenziselwa ukugcoba i-adsorbent ngokusebenzisa i-valve eshintshayo (ngokungafani nesiqondiso se-adsorption), kanti i-vacuum degree ingu-0.45 ~ 0.5BARg.

Amanzi amunciwe, i-carbon dioxide, i-nitrogen kanye nenani elincane lezinto zegesi akhishwa emkhathini futhi i-adsorbent iyavuselelwa.
Umkhangisi ngamunye uyashintsha phakathi kwezinyathelo ezilandelayo:
- adsorption
- Ukususwa
- nginyathela
Izinyathelo zenqubo eziyisisekelo ezingenhla zilawulwa ngokuzenzakalela yi-PLC nokushintsha uhlelo lwe-valve.
