Ngithola ubuchwepheshe be-PSA obumangazayo ngoba lihlukanisa amagesi ngokususelwa kwizakhiwo zazo ezihlukile ze-adsorption ngaphansi kwezimo zengcindezi ezihlukile. Le nqubo idlala indima ebalulekile ezimbonini ezidinga amagesi ahlanzekile aphezulu. Isibonelo, aIsitshalo se-PSA OxygenKhiqiza kahle umoya-mpilo ngokuhlukanisa nakwamanye amagesi. Ukunemba kwayo nokwethenjwa kwenza kube kubaluleke kakhulu kwizicelo zezimboni.
Ukuthathwa Key
- Ubuchwepheshe be-PSA buhlukanisa amagesi besebenzisa izici zabo ezikhethekile engcindezi ehlukene. Kubalulekile ukwenza amagesi ahlanzekile kakhulu.
- Indlela ye-PSA inezinyathelo ezine eziphambili: ama-adsorption, ukucindezelwa, ukuhlanza, nokucindezela. Isinyathelo ngasinye sisiza ukuhlukanisa amagesi kahle.
- Ukucindezela okulungile nokushisa kuyisihluthulelo se-PSA ukusebenza kahle. Lokhu kuqinisekisa ukusebenza okuqinile kanye negesi esezingeni elifanele.
Izigaba ezibalulekile ze-PSA
Ukuqonda izigaba ezibalulekile zengcindezelo Swing Adsorption (PSA) kuyangisiza ukuba ngiqonde ukuthi lobu buchwepheshe bufinyelela kanjani ukwahlukana kwegesi. Isigaba ngasinye sidlala indima ebalulekile ekuqinisekiseni kahle le nqubo isebenza kahle futhi ihambisa amagesi ahlanzekile aphezulu.
Isigaba se-adsorption
Isigaba se-adsorption yilapho umlingo uqala khona. Ngethula ingxube yegesi ohlelweni lwePSA ngaphansi kwengcindezi ephezulu. Ngalesi sigaba, amagesi athile anamathela ebusweni bezinto ezi-adsorbent ngaphakathi kohlelo. Isibonelo, esitshalweni se-psa oxygen, ama-molecule we-nitrogen abopha ama-adsorbent, avumele umoya-mpilo ukuthi adlule njengomkhiqizo oyinhloko. Indwangu ye-adsorbent, imvamisa ye-zeolite noma ikhabhoni eyenziwe yasebenza, ikhethwa ngokucophelela ngekhono layo lokudonsela amagesi athile ngokukhetha. Lesi sigaba siqinisekisa ukuthi igesi oyifunayo ihlukaniswe ngempumelelo.
Isigaba Sokudukiswa
Isigaba Sokudukiswa ngokufanayo. Nginciphisa ingcindezi ngaphakathi kohlelo, okwenza amagesi ahlelwe ama-adsorbed akhulule ezintweni ezi-adsorbent. Lesi sinyathelo sivuselela ama-adsorbent, asilungiselela umjikelezo olandelayo. Esitshalweni se-PSA Oxygen, lesi sigaba siqinisekisa ukuthi i-nitrogen ixoshwa, igcina ukusebenza kahle kwe-adsorbent yokusebenza okuqhubekayo. Amagesi akhishwe ngokuvamile akhishwa noma aqoqwe okunye ukusetshenziswa.
Inqubo eqhubekayo yokuhamba ngebhayisikile
I-PSA isebenza njengenqubo eqhubekayo yokuhamba ngebhayisikile. Ngishintshanisa phakathi kwezigaba ze-adsorption kanye nezokudutshulwa ukuze ngilondoloze ukuhanjiswa okuqinile kwegesi ehlanziwe. Amakholamu amaningi ama-adsorption avame ukusebenza eTandem ukuqinisekisa ukukhiqizwa okungaphazanyiswa. Le nqubo yokuhamba ngebhayisikile yikho okwenza ubuchwepheshe be-PSA buthembekile futhi busebenze kahle kwizicelo zezimboni.
Ukuguqulwa komthungo phakathi kwalezi zigaba yikho okwenza izinhlelo ze-PSA zinikeze imiphumela engaguquki, ikakhulukazi kuzinhlelo zokusebenza njengokukhiqizwa komoya-mpilo.
Inqubo ye-PSA yesinyathelo esingu-4
Isinyathelo 1: Adsorption
Inqubo iqala nge-adsorption. Ngethula ingxube yegesi ohlelweni lwePSA ngaphansi kwengcindezi ephezulu. Izinto ezi-adsorbent zithola ukukhetha okungafuneki, njenge-nitrogen, ngenkathi zivumela igesi oyifunayo, njenge-oksijini, ukudlula. Lesi sinyathelo sibucayi kuIsitshalo se-PSA Oxygen, lapho umoya-mpilo uhlukaniswa namanye amagesi ngokunemba. Izinto ze-adsorbent, imvamisa ye-zeolite, zidlala indima ebalulekile ekuqinisekiseni ukusebenza kahle kwalesi sigaba.
Isinyathelo 2: Ukucindezelwa
Okulandelayo, nginciphisa ingcindezi ohlelweni. Lesi sinyathelo sikhipha amagesi asetshenzisiwe avela ezintweni ezi-adsorbent. Isigaba sokucindezelwa sivuselela ama-adsorbent, asilungiselela umjikelezo olandelayo. Amagesi akhishwe akhishwe noma aqoqwe ezinye izinhloso. Lesi sigaba siqinisekisa ukuthi uhlelo lusebenza ngokuqhubekayo ngaphandle kokuphazamiseka.
Isinyathelo 3: Hlanza
Ngesikhathi sesigaba sokuhlanza, ngethula inani elincane legesi ehlanziwe libuyele ohlelweni. Le gesi igeleza ngezinto ezi-adsorbent, isuse noma yikuphi ukungcola okusele. Lesi sinyathelo sithuthukisa ukusebenza kwe-adsorbent futhi siqinisekise ubumsulwa bomkhiqizo wokugcina. Esitshalweni se-PSA Oxygen, lesi sigaba siqinisekisa ukulethwa komoya-mpilo osezingeni eliphakeme.
Isinyathelo 4: Ukucindezela kabusha
Ekugcineni, ngibuyisela uhlelo ekucindezelweni kwalo okusebenzayo. Lesi sinyathelo silungiselela impahla e-adsorbent yesigaba esilandelayo se-adsorption. Ukucindezela kabusha kuqinisekisa uhlelo lugcina isigqi esiqinile, luvumela ukukhiqizwa okuqhubekayo kwegesi. Ukuguqulwa komthungo phakathi kwalezi zinyathelo kuqokomisa ukusebenza kahle kwezobuchwepheshe be-PSA.
Isinyathelo ngasinye kwinqubo ye-PSA sineqhaza ekuthembekeni kwayo nasekusebenzeni kahle, okwenza kube yikhekhe elikhethwayo lokuhlukaniswa kwegesi yezimboni.
Isitshalo se-PSA Oxygen kanye nezimo zokusebenza
Ingcindezi kanye nezidingo zokushisa
Ngihlala ngiqinisekisa ukuthi isitshalo se-PSA Oxygen sisebenza ngaphansi kwengcindezi efanelekile kanye nezimo zokushisa. Uhlelo ngokujwayelekile ludinga ingcindezi ephezulu ngesikhathi sesigaba se-adsorption ukukhulisa ukusebenza kahle kwegesi. Ngokukhiqizwa komoya-mpilo, ngigcina izingcindezi eziphakathi kuka-4 no-10 bar, kuya ngohlelo oluthile. Izinga lokushisa lidlala indima ebalulekile. Ngigcina uhlelo emazingeni okushisa akhona ukuze aqinisekise ukuthi izinto ze-adsorbent zisebenza ngempumelelo. Ukushisa okwedlulele kunganciphisa ukusebenza kahle kwe-adulbent, ngakho-ke ukugcina izimo ezinzile zibalulekile ukuthola imiphumela engaguquki.
Isikhathi sokujikeleza kanye nokusebenza kahle
Isikhathi sokujikeleza sithinta ngokuqondile ukusebenza kahle kwesitshalo se-psa oxygen. Ngiklama uhlelo ukuqedela umjikelezo ngamunye kungakapheli imizuzu embalwa, luqinisekisa ukunikezwa okuqhubekayo komoya-mpilo. Izikhathi ezimfushane zomjikelezo zithuthukisa umkhiqizo kepha zidinga ukulawulwa okuqondile ukuze ulondoloze ubumsulwa begesi. Ngithola ukuthi leso sikhathi somjikelezo wokulinganisa nokwakhiwa kabusha kwe-adsorbent kubalulekile ekufezekiseni ukusebenza kahle. Ngokwenza kahle la mapharamitha, ngikwazi ukuqinisekisa ukuthi isitshalo sihambisa ukusebenza okuthembekile ngenkathi sinciphisa ukusetshenziswa kwamandla.
Izinto ezisetshenziswa kuma-adsorbents
Ukukhetha kwezinto ezisetshenziswayo ze-adsorbent kunquma ukusebenza kwe-Isitshalo se-PSA Oxygen. Imvamisa ngisebenzisa i-zeolite ngenxa yekhono layo elihle kakhulu lokukhetha i-adcerb nitrogen ngenkathi ngivumela umoya-mpilo ukuthi udlule. I-Carbon ecushiwe enye inketho yezinhlelo ezithile. Lezi zinto zokwenziwa zihlala isikhathi eside futhi zikwazi ukubekezelela ukubekezelela imijikelezo ephindaphindwayo ye-adcerption ne-demorption. Ngaso sonke isikhathi ngibeka phambili ama-adsorbents asezingeni eliphakeme ukuqinisekisa ukuthi lesi sitshalo sisebenza kahle futhi sikhiqiza umoya-mpilo wokuhlanza okuphezulu.
Inhlanganisela yezimo ezisebenzayo zokusebenza kanye nezinto zokwakha ezithuthukile ze-adsorbent ziqinisekisa ukuthi isitshalo se-oxygen ye-PSA ihambisa ukusebenza okuhlukile ezinhlalwane zezimboni.
Ingcindezi Swing Adsorption (PSA) isebenza ngokufaka i-Leverighting Gas Cassorption Properties ngaphansi kwezingcindezi ezahlukahlukene. Ngithola amandla alo okuletha amagesi amsulwa aphezulu asebenza kahle futhi ahlukahlukene.
Ubuchwepheshe be-PSA budlula ezihlolweni zezimboni, benikeza ukuthembeka nokunemba. Inqubo yayo eqhubekayo yokuhamba ngebhayisekili iqinisekisa ukusebenza okungaguquki, okwenza kube yisixazululo esisemqoka sezidingo zesimanje zokuhlukaniswa kwegesi.
Umthandi
Yiziphi izimboni ezisebenzisa ubuchwepheshe be-PSA?
Ubuchwepheshe be-PSA busebenza izimboni ezinjengokunakekelwa kwempilo, ukukhiqiza, nokusebenza kokudla. Ngivame ukukubona kusetshenziselwa ukukhiqizwa komoya-mpilo, ukukhiqizwa kwe-nitrogen, nokuhlanzwa kwegesi.
Ngabe i-PSA ihluke kanjani ekwahlukanisweni kwe-crysogenic?
I-PSA isebenza emazingeni okushisa aveent futhi isebenzisa ama-adderbents we-gesi detration. Ukwahlukana kwe-Cryogenic kuncike kumagesi apholile kumazinga okushisa aphansi kakhulu e-liquefaction.
Ingabe izinhlelo ze-PSA zingaphatha ukusebenza okuqhubekayo?
Yebo, amasistimu we-PSA exchal ekusebenzeni okuqhubekayo. Ngibadidizela ngamakholomu ama-adsorption amaningi ukuqinisekisa ukukhiqizwa kwegesi engaphazanyiswa nokusebenza okungaguquki.
