Amashanyarazi ya VPSA

Ibikoresho bya ogisijeni ya Psa, ukurikije ubushyuhe bwicyumba hamwe n’umuvuduko w’ikirere, UKORESHEJWE na molekile idasanzwe ya VPSA kugirango uhitemo guhitamo azote, dioxyde de carbone n’amazi n’ibindi byanduye mu kirere, kugirango ubone ogisijeni ifite isuku nyinshi (93 ± 2%) ).

Umusemburo wa ogisijeni gakondo usanzwe ukoresha uburyo bwo gutandukanya cryogenic, bushobora kubyara ogisijeni ifite isuku nyinshi. Nyamara, ibikoresho bifite ishoramari ryinshi, kandi ibikoresho bikora munsi yumuvuduko mwinshi nubushyuhe bukabije. Igikorwa kiragoye, igipimo cyo kubungabunga kiri hejuru, kandi ingufu zikoreshwa ni nyinshi, kandi akenshi bikenera kunyura mumasaha menshi kugirango bisanzwe bitange gaze nyuma yo gutangira.

Kuva ibikoresho bya psa ogisijeni byinjira mu nganda, ikoranabuhanga ryateye imbere byihuse, kubera ko imikorere y’ibiciro ryayo ugereranije n’umusaruro muke kandi ibisabwa by’isuku ntabwo biri hejuru cyane mu bihe bifite irushanwa rikomeye, bityo rikoreshwa cyane mu gushonga, itanura rya ogisijeni itunganijwe, guhumeka neza, itanura ryikirahure, gutunganya amazi mabi nindi mirima.

Ubushakashatsi bwo murugo kuri tekinoroji bwatangiye kare, ariko mugihe kirekire iterambere riratinda.

Kuva mu myaka ya za 90, ibyiza by'ibikoresho byo gukora psa ogisijeni byamenyekanye buhoro buhoro n'Abashinwa, kandi mu myaka yashize, ibikoresho bitandukanye byashyizwe mu bikorwa.

Ibikoresho bya psa VPSA bitanga umusaruro wa Hangzhou Boxiang Gas Equipment Co., Ltd. bifite umwanya wambere mubijyanye n’inganda z’ifumbire, kandi ingaruka zabyo ni nziza cyane.

Imwe munzira zingenzi ziterambere rya psa nukugabanya umubare wa adsorbent no kuzamura ubushobozi bwibikoresho. Nyamara, kunoza amashanyarazi ya molekile kugirango umusaruro wa ogisijeni uhora bikorwa mu cyerekezo cyinshi cya azote ya adsorption, kubera ko imikorere ya adsorption yimashanyarazi ya molekile ari ishingiro rya PSA.

Amashanyarazi ya molekile afite ubuziranenge agomba kuba afite azote nyinshi ya azote na ogisijeni yo gutandukanya, kwiyuzuza kwa adsorption n'imbaraga nyinshi.

Psa ikindi cyerekezo cyingenzi cyiterambere ni ugukoresha uruziga rugufi, ntirukeneye gusa ireme ryizewe rya molekile ya elegitoronike, icyarimwe bigomba gushingira kumunara wa adsorption umunara wimbere, kugirango wirinde bishobora gutera ibicuruzwa kuba bibi kandi ibibi byo gukwirakwiza bidahuje ingufu za gaze mu munara wa adsorption, kandi inashyira imbere ibisabwa hejuru kugirango uhindure ibinyugunyugu.

Mubikorwa byinshi bya ogisijeni ya PSA, PSA, VSA na VPSA birashobora gushyirwa mubwoko butatu.

PSA nigikorwa kinini cyumuvuduko wa adsorption ikirere cya desorption inzira. Ifite ibyiza byibice byoroheje nibisabwa bike kuri sikile ya molekile, nibibi byo gukoresha ingufu nyinshi, bigomba gukoreshwa mubikoresho bito.

VSA, cyangwa umuvuduko wikirere adsorption vacuum desorption inzira, ifite ibyiza byo gukoresha ingufu nke hamwe nibibi byibikoresho bigoye ugereranije nishoramari ryinshi.

VPSA ni inzira ya vacuum desorption ikoresheje umuvuduko w'ikirere. Ifite ibyiza byo gukoresha ingufu nke hamwe nubushobozi buhanitse bwa elegitoronike. Igishoro cyose cyibikoresho kiri hasi cyane ugereranije nibikorwa bya VSA, kandi ibibi ni nkibisabwa cyane kugirango amashanyarazi ya molekile na valve.

Gazi ya Hangzhou Boxiang ifata inzira ya VPSA, kandi igatera imbere cyane mubikorwa gakondo no mubikorwa, ibyo ntibigabanya gusa gukoresha ingufu kugeza byibuze (bivuga ikoreshwa rya sikeli imwe ya molekile imwe), ariko kandi igera kuntego yo koroshya na miniaturizasi y'ibikoresho, igabanya ishoramari, kandi ifite imikorere ihanitse / igipimo cyibiciro.

Sisitemu yo gukora psa yose ya ogisijeni igizwe ahanini na blower, pompe vacuum, guhinduranya valve, imashini hamwe na ogisijeni yumuvuduko wa ogisijeni.

Iyo umukungugu umaze gukurwaho na filteri yo guswera, umwuka mbisi uhindurwamo 0.3 ~ 0.4 Barg na Roots blower hanyuma ikinjira muri adsorbents.

Adsorbent yuzuye muri adsorbent, aho amazi, dioxyde de carbone, hamwe n’ibindi bikoresho bigize gaze byandikirwa mu iyinjizwa rya adsorbent na alumina ikora hepfo, hanyuma azote ikamenyekana na alumina ikora na zeolite. hejuru yicyuma cya 13X.

Oxygene (harimo na argon) nikintu kitamenyeshejwe kandi kiva mumasoko yo hejuru ya adsorber kugeza kuri tank ya ogisijeni nkibicuruzwa.

Iyo adsorbent yamamajwe kurwego runaka, adsorbent izagera kumyuzure. Muri iki gihe, pompe ya vacuum izakoreshwa mu gukuramo adsorbent binyuze muri valve ihinduranya (bitandukanye nicyerekezo cya adsorption), naho impamyabumenyi ya vacuum ni 0.45 ~ 0.5BARg.

Amazi yinjiye, dioxyde de carbone, azote hamwe n’ibindi bikoresho bya gaze bisohorwa mu kirere maze adsorbent ikavuka.
Buri adsorber isimburana hagati yintambwe zikurikira:
- adsorption
- desorption
- kashe
Intambwe eshatu zingenzi zavuzwe haruguru zihita zigenzurwa na PLC hamwe na sisitemu yo guhinduranya valve.
