I-VPSA Oxygen Generator

Imishini yokukhiqiza i-oxygen ye-Psa, ngaphansi kwesimo sokushisa kwegumbi nokucindezela komkhathi, ISEBENZISA isisefo esikhethekile se-VPSA ukuze imunce i-nitrogen, i-carbon dioxide namanzi nokunye ukungcola emoyeni, ukuze ithole umoya-mpilo ngokuhlanzeka okuphezulu (93 ± 2% ).

Ukukhiqizwa komoyampilo wendabuko ngokuvamile kusebenzisa indlela yokuhlukanisa i-cryogenic, engakhiqiza umoya-mpilo ngokuhlanzeka okuphezulu. Kodwa-ke, imishini inokutshalwa kwezimali okuphezulu, futhi imishini isebenza ngaphansi kwesimo sokucindezela okukhulu nokushisa okuphansi kakhulu. Umsebenzi unzima, izinga lokunakekela liphezulu, futhi ukusetshenziswa kwamandla kuphezulu, futhi ngokuvamile kudingeka kudlule inqwaba yamahora ukuze kuvamise ukukhiqiza igesi ngemva kokuqala.

Kusukela imishini yokukhiqiza umoya-mpilo ye-psa ingene ezimbonini, ubuchwepheshe buthuthuke ngokushesha, ngoba ukusebenza kwayo kwentengo kunebanga eliphansi lesivuno futhi izidingo zokuhlanzeka aziphezulu kakhulu esimweni sinokuncintisana okuqinile, ngakho-ke isetshenziswa kabanzi ekuncibilikeni, kuqhuma isithando somlilo ukucebisa umoya-mpilo, ukuxubha kwe-pulp, isithando somlilo sengilazi, ukuhlanzwa kwamanzi angcolile kanye neminye imikhakha.

Ucwaningo lwasekhaya ngalobu buchwepheshe luqale ngaphambili, kodwa esikhathini eside ukuthuthukiswa kuhamba kancane.

Kusukela ngawo-1990, izinzuzo zemishini yokukhiqiza umoya-mpilo ye-psa ziye zaqashelwa kancane kancane abantu baseShayina, futhi eminyakeni yamuva nje, izinqubo ezihlukahlukene zemishini ziye zafakwa ekukhiqizeni.

Imishini yokukhiqiza umoya-mpilo ye-psa VPSA ye-Hangzhou Boxiang Gas Equipment Co., Ltd. inesikhundla esihamba phambili emkhakheni wemboni kamanyolo, futhi umphumela wayo uphawuleka kakhulu.

Enye yezindlela eziyinhloko zokuthuthukisa i-psa ukunciphisa inani le-adsorbent kanye nokuthuthukisa umthamo wokukhiqiza wemishini. Kodwa-ke, ukuthuthukiswa kwezisefo zamangqamuzana okukhiqiza umoya-mpilo kuhlale kwenziwa ngendlela yezinga eliphezulu le-nitrogen adsorption, ngoba ukusebenza kwe-adsorption yama-molecular sieves kuyisisekelo se-PSA.

Isisefo samangqamuzana esinekhwalithi enhle kufanele sibe ne-coefficient yokuhlukaniswa kwe-nitrogen ne-oxygen ephezulu, umthamo we-saturation adsorption namandla aphezulu.

I-Psa enye inkomba enkulu yentuthuko ukusebenzisa umjikelezo omfushane, ayidingi kuphela ikhwalithi eqinisekisiwe yesisefo samangqamuzana, ngesikhathi esifanayo kufanele isekelwe ekuthuthukisweni kwesakhiwo sangaphakathi sombhoshongo we-adsorption, ukuze ugweme okungase kubangele ukuthi umkhiqizo ube mubi futhi ububi bokusatshalaliswa okungajwayelekile kokugxilwa kwegesi embhoshongweni we-adsorption, futhi kuphinde kubeke phambili izidingo eziphakeme zokushintshwa kwevalvu uvemvane.

Ezinqubweni eziningi zokukhiqiza umoya-mpilo we-PSA, i-PSA, i-VSA ne-VPSA ngokuvamile ingahlukaniswa ngezinhlobo ezintathu.

I-PSA iyinqubo ye-super pressure adsorption atmospheric desorption process. Inezinzuzo zeyunithi elula kanye nezidingo eziphansi ze-sieve zamangqamuzana, kanye nokubi kokusetshenziswa kwamandla aphezulu, okufanele kusetshenziswe emishinini emincane.

I-VSA, noma inqubo ye-atmospheric adsorption vacuum desorption, inenzuzo yokusebenzisa amandla aphansi kanye nokubi kwemishini eyinkimbinkimbi uma kuqhathaniswa kanye nokutshalwa kwezimali okuphelele okuphezulu.

I-VPSA iyinqubo ye-vacuum desorption ngokusebenzisa ingcindezi yasemkhathini. Inezinzuzo zokusebenzisa amandla aphansi kanye nokusebenza kahle okuphezulu kwe-sieve yamangqamuzana. Isamba sokutshalwa kwezimali kwezinto zokusebenza siphansi kakhulu kunaleso senqubo ye-VSA, futhi ukonakala kuyizidingo eziphakeme kakhulu zesisefo samangqamuzana namavalvu.

Igesi ye-Hangzhou Boxiang yamukela inqubo ye-VPSA, futhi yenza intuthuko enkulu enqubweni nasenqubweni evamile, engagcini nje ukunciphisa ukusetshenziswa kwamandla kuze kube sezingeni eliphansi (ibhekisela ekusetshenzisweni kwesisefo se-molecular brand efanayo), kodwa futhi ifinyelela umgomo wokwenza lula kanye nokwenza okuncane. okokusebenza, yehlisa ukutshalwa kwezimali, futhi inenani eliphezulu lokusebenza/intengo.

Lonke uhlelo lokukhiqiza umoya-mpilo we-psa ikakhulukazi lwakhiwe i-blower, i-vacuum pump, i-switching valve, i-absorber kanye neyunithi ye-oxygen pressure booster unit ye-oxygen balance balance.

Ngemva kokususwa kwezinhlayiya zothuli ngesihlungi sokumunca, umoya ongahluziwe ucindezelwa ku-0.3~0.4 Barg by Roots blower bese ungena kwenye yama-adsorbent.

I-adsorbent igcwaliswa ku-adsorbent, lapho amanzi, i-carbon dioxide, kanye nenani elincane lezinye izingxenye zegesi kufakwa endaweni yokungena ye-adsorbent nge-alumina ecushiwe phansi, bese i-nitrogen ikhangwa yi-alumina ne-zeolite ecushiwe. phezulu kwesisefo se-molecular 13X.

I-oksijeni (kuhlanganise ne-argon) iyisakhi esingafakwanga i-adsorbed futhi ikhishwa iphuma endaweni ephezulu ye-adsorber iye ethangini lebhalansi ye-oxygen njengomkhiqizo.

Uma i-adsorbent ikhangiswe ngezinga elithile, i-adsorbent izofinyelela isimo sokugcwala. Ngalesi sikhathi, iphampu yevacuum izosetshenziselwa ukuvala i-adsorbent ngevalvu yokushintsha (ngokungqubuzana nendawo ye-adsorption), futhi idigri yevacuum ingu-0.45~ 0.5BARg.

Amanzi amuncwa, i-carbon dioxide, i-nitrogen kanye nenani elincane lezinye izingxenye zegesi zimpontshelwa emkhathini bese i-adsorbent ivuselelwa.
I-adsorber ngayinye ishintshana phakathi kwezinyathelo ezilandelayo:
- i-adsorption
- ukudangala
- ukunyathela
Izinyathelo ezintathu zenqubo eziyisisekelo ezingenhla zilawulwa ngokuzenzakalelayo yi-PLC kanye nesistimu ye-valve yokushintsha.
