Ibisobanuro ku bicuruzwa
Ibikoresho bya ogisijeni ya Psa, ukurikije ubushyuhe bwicyumba hamwe n’umuvuduko w’ikirere, UKORESHEJWE umwihariko wa molekile 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 yaryo igiciro ugereranije no mu musaruro muke kandi ibisabwa kugira ngo isuku ntiri 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 ubwiza bwumuti wa molekile gusa, 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 hamwe nibikorwa, ibyo ntibigabanya gusa gukoresha ingufu kugeza byibuze (bivuga ikoreshwa ryikimenyetso kimwe cya molekile), ariko kandi kigera 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 byamamazwa 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.
Ihame ry'akazi
Intambwe eshatu zingenzi zavuzwe haruguru zihita zigenzurwa na PLC hamwe na sisitemu yo guhinduranya valve.
1. Ihame ryo gutandukanya ikirere psa kubyara ogisijeni
Ibintu nyamukuru bigize ikirere ni azote na ogisijeni. Kubwibyo, adsorbents hamwe na adsorption itandukanye ya azote na ogisijeni irashobora gutoranywa kandi inzira yikoranabuhanga irashobora gutegurwa gutandukanya azote na ogisijeni kugirango bitange ogisijeni.
Azote na ogisijeni byombi bifite ibihe bya kane, ariko umwanya wa kane wa azote (0.31 A) nini cyane kuruta ogisijeni (0,10 A), bityo azote ifite imbaraga zo kwinjiza imbaraga za molekile ya zeolite kuruta ogisijeni (azote ikoresha imbaraga zikomeye hamwe na ion hejuru. ya zeolite).
Kubwibyo, iyo umwuka unyuze muburiri bwa adsorption irimo zeolite adsorbent munsi yigitutu, azote yandikwa na zeolite, na ogisijeni ntiyemerwa cyane, bityo ikungahazwa mugice cya gaze ikasohoka ikava muburiri bwa adsorption, bigatuma ogisijeni na azote bitandukana na shaka ogisijeni.
Iyo icyuma cya molekuline cyamamaza azote hafi yo kwiyuzuzamo, umwuka urahagarara kandi umuvuduko wigitanda cya adsorption ukagabanuka, azote yamamajwe nigitereko cya molekile irashobora gutabwa hanze, kandi icyuma cya molekile gishobora kuvugururwa no kongera gukoreshwa.
Oxygene irashobora kubyara ubudahwema guhinduranya ibitanda bibiri cyangwa byinshi bya adsorption.
Ingingo yo guteka ya argon na ogisijeni yegereye undi, biragoye rero kubitandukanya, kandi birashobora gukungahaza hamwe mugice cya gaze.
Kubwibyo, ibikoresho bya psa ogisijeni mubisanzwe birashobora kubona gusa 80% ~ 93% bya ogisijeni, ugereranije nubushakashatsi bwa 99.5% cyangwa burenga ogisijeni mubikoresho bitandukanya ikirere, bizwi kandi ko bikungahaye kuri ogisijeni.
Ukurikije uburyo butandukanye bwa desorption, umusaruro wa psa ogisijeni urashobora kugabanywamo
Inzira ebyiri
1. Inzira ya PSA: adsorption yumuvuduko (0.2-0.6mpa), desorption yo mu kirere.
Ibikoresho bitunganya PSA biroroshye, ishoramari rito, ariko umusaruro muke wa ogisijeni, gukoresha ingufu nyinshi, bikwiranye no gukora ogisijeni ntoya (muri rusange <200m3 / h).
2. Inzira ya VPSA: adsorption munsi yumuvuduko usanzwe cyangwa hejuru gato yumuvuduko usanzwe (0 ~ 50KPa), gukuramo vacuum (-50 ~ -80kpa) desorption.
Ugereranije na PSA, ibikoresho bya VPSA biragoye, ishoramari ryinshi, ariko gukora neza, gukoresha ingufu nke, bikwiranye nigihe kinini cyo gukora ogisijeni.
Kubikorwa byukuri byo gutandukana, ibindi bice bigize ikirere nabyo bigomba gusuzumwa.
Ubushobozi bwa adsorption ya dioxyde de carbone n'amazi kuri adsorbents zisanzwe muri rusange biruta cyane ibya azote na ogisijeni. Amatangazo yamamaza arashobora kuzuzwa muburiri bwa adsorption hamwe na adsorbents ikwiye (cyangwa gukoresha ogisijeni ikora adsorbents ubwayo) kugirango zishobore gukururwa no gukurwaho.
Rusange rusange muri rusange ibikoresho bya VPSA bitanga umusaruro:
Ø gukoresha tekinoloji igezweho, ikoranabuhanga rikuze, gukoresha ingufu nke nigiciro cyibikorwa byububiko bubiri psa ogisijeni ikora;
Gutekereza no, binyuze mu gusuzuma ifishi yuzuye y'ibikoresho, ubuziranenge bwo kwemeza kwizerwa no gutuza kw'imikorere ya sisitemu;
Ø ibikoresho, imikorere yoroheje;
Control kugenzura byimikorere cyane, gucunga neza icyumba cyo kugenzura hagati;
Nziza umutekano wa sisitemu, gukurikirana ibikoresho, ingamba zo gukumira amakosa kugirango tunoze;
Ø nta kwangiza ibidukikije;
Equipment ibikoresho bya ogisijeni kugirango bisohore bwa nyuma bya Repubulika y’Ubushinwa ibipimo ngenderwaho by’igihugu hamwe n’ibipimo bya minisiteri y’inganda.
