Umhlahlandlela Ophelele Wesimiso Sokusebenza Sama-PSA Nitrogen Generator

Ijeneretha ye-nitrogen ye-PSA ngokuvamile iyisisombululo sokunikezwa kwe-nitrogen njalo ngaphandle kwesidingo sokuthenga amasilinda njalo. Ihlukanisa i-nitrogen nomoya-mpilo endaweni, isebenzisa umoya ojwayelekile, ukuze ihlangabezane nezidingo zamabhizinisi ukuze ithole ugesi ophephile uma kudingeka. Lokhu kuvame ukusetshenziswa ezimbonini zokupakisha ukudla, ezimbonini zokusika nge-laser, ngisho nasezimbonini ze-elekthronikhi. Izinkampani zingakhetha ukukhiqiza i-nitrogen uma kudingeka futhi zingadingi ukulinda ukulethwa kwayo. Kulula kodwa umqondo ngemuva kwayo uhlakaniphile kancane futhi kungaba usizo ukuyihlola isinyathelo ngesinyathelo.

I-Logic Eyisisekelo Yokuhlukaniswa Komoya Ekukhiqizweni Kwe-nitrogen

Umqondo oyinhloko ngemuva kwejenereyitha ye-nitrogen ye-PSA ukukwazi ukuhlukanisa i-nitrogen (N2) kwamanye amagesi emoyeni, ikakhulukazi i-oxygen. Iqala ngomoya ojwayelekile ovela emkhathini. Umoya uyacindezelwa, noma ufakwe endaweni encane lapho amagesi elawulwa kalula futhi angathuthwa ohlelweni. Umoya uyacindezelwa bese udlula ngesihlungo se-carbon molecular esiyingqayizivele ukuze uwucindezele. Ama-pores ale nto mancane kakhulu futhi akhetha kakhulu. Ama-molecule e-oxygen mancane kancane kunama-molecule e-N₂ futhi ahamba ngendlela ehlukile kancane, ngakho-ke angabanjwa kalula esihlungweni. Nokho, ama-molecule e-nitrogen ayadlula futhi aqhubeke. Ngokuvamile amabili alawa matanki azosebenza. Elinye itanki lizohlanzwa futhi liphinde lisethwe futhi itanki le-oxygen lizoqoqwa. Ingxenye "yokushintsha kwengcindezi" yenqubo ukushintshana phakathi kwalokhu okubili. Uhlangothi olulodwa lungaphansi kwengcindezi ephezulu yokuhlukanisa amagesi bese ingcindezi incishiswa, ukuze i-oxygen isuswe ogibeni. Inqubo iyaphindwa. Ngalesi sishintshi, i-nitrogen igcinwa igeleza njalo. Lesi yisizathu sokuthi izimboni zingaqinisekisa ukuthi izosetshenziswa njalo. I-nitrogen isetshenziswa emgqeni wokupakisha ukudla ukususa umoya-mpilo ngaphakathi kwamaphakheji avaliwe ukuze kwandiswe isikhathi sokuphila kweshelufu sokudla okulula neminye imikhiqizo yokudla. Ema-workshop okusika nge-laser, i-nitrogen isetshenziselwa ukunikeza isivikelo ekushiseni noma ekushiseni insimbi ukuze kwenziwe ukusika kuhlanzeke. Imfihlo yokuphila ukuthi akukho ukusabela okuyinkimbinkimbi okuhilelekile nokuthi akukho makhemikhali asetshenziswayo. Kudinga kuphela ukusetshenziswa komoya, izinguquko zokucindezela kanye nezinto zokungenisa. Uhlelo luhlelwe futhi ukusebenza kwalo kugcinwa njengoba kudingeka ngokuphathwa kokunyakaza komoya. Ngamagama alula, I-PSA nitrogen generator iyisihlungi esihlakaniphile esikwaziyo "ukuvimba" umoya-mpilo futhi sivumele i-nitrogen ukuthi idlule.

Indlela Ama-Carbon Molecular Sieves Ahlukanisa Ngayo I-Oxygen Ne-Nitrogen

Kuhlelo lwe-nitrogen lwe-PSA, "umsebenzi" wenziwa ngento eyaziwa ngokuthi isihlungo se-carbon molecular, noma i-CMS nje. Ifana nama-granule amancane amnyama, kodwa inezimbobo eziningi ezincane ngaphakathi kwenhlamvu ngayinye ukulawula ukuhamba kwamagesi. Umoya uqukethe izakhi ze-nitrogen nomoya-mpilo ezinezakhiwo ezihlukile kancane uma zicindezelwa ezindaweni ezincane. Ama-molecule e-oxygen asebenza kancane futhi ahamba ngendlela evumela ukubanjwa kwawo ezimbobeni ezincane kakhulu ze-CMS. Nokho, ama-molecule e-nitrogen "ayashelela", futhi angadlula kalula. Umbhede we-CMS ucindezelwa umoya ocindezelwe, ngaleyo ndlela uqhube umoya-mpilo ne-nitrogen embhedeni futhi. Uma umoya-mpilo ungavunyelwe ukudlula ezimbobeni, uzohlala ngaphakathi kwesakhiwo. Lokhu kubizwa ngokuthi ukumuncwa lapho ama-molecule egesi enamathela ebusweni bento. Igesi yomkhiqizo iqukethe i-nitrogen, eqhubeka nokugeleza futhi iphume ohlelweni. Isithombe esihle okufanele usicabangele "iphaseji" elinabantu abaningi kulo kanye nomnyango omncane. I-oxygen ifana nabantu abanezikhwama ezinkulu phambi kwabo ezinamathele emnyango; I-nitrogen ifana kakhulu nabantu abanezikhwama ezincane phambi kwabo futhi ingena kahle. Uhlelo aluncikile embhedeni owodwa wesihlungo. Umbhede owodwa usetshenziselwa ukubamba umoya-mpilo kanti omunye ufakwa umoya ukuze unciphise umoya-mpilo ovalelekile bese uwususa. Yisigaba sokusetha kabusha esibalulekile ngoba sivumela isihlungo ukuthi sisebenze futhi. Ngemva kwalokho siyashintshana phakathi kwemibhede emibili. Lona umjikelezo oqhubekayo obalulekile ukuze kulondolozwe ukukhiqizwa kwe-N okuzinzile. Lokhu kungavela endaweni yokusika nge-laser lapho kudingeka khona ukugeleza kwe-nitrogen okuhlanzekile ukuvimbela insimbi ekungcoliseni okusetshenziswayo. I-CMS isusa umoya-mpilo ngaphambi kokufika komoya-mpilo emishinini, okusiza ekugcinweni kwemiphetho yokusika ehlanzekile. I-CMS iyasebenza kakhulu hhayi kuphela kokuqukethwe, kodwa ngoba isebenza ngaphansi kwengcindezi. Iba uhlobo lwesihlungi esizihlela kabusha njalo futhi sikhiqize i-nitrogen ngaphandle kokuphazamiseka.

Inqubo Ephelele Yokusebenza Kokudonswa Kwe-Dual-Tower Pressure Swing Adsorption

Uhlelo lokumunca umbhoshongo ophindwe kabili olushintshashintshayo lwenzelwe ukugcina ukugeleza okuqhubekayo kwe-nitrogen. Lunemibhoshongo emibili equkethe inani elifanayo lesihlungo sama-molecule e-carbon, asetshenziswa ngokushintshana ukwenza inqubo yokuhlukanisa umoya. Umjikelezo uqala lapho umoya ocindezelwe ungena embhoshongweni wokuqala. Lapho ingcindezi iphezulu, ngaphakathi kwama-molecule omoya-mpilo kunamathela ezintweni zesihlungo. I-nitrogen ayibambeki kalula futhi idlula embhoshongweni bese iphuma njengegesi yomkhiqizo. Izindima bese zishintsha ngemva kwesikhathi esifushane. Umbhoshongo wokuqala uqala ukukhulula ingcindezi bese uqala ukuvuselelwa kanti umbhoshongo wesibili uqala ukukhiqiza i-nitrogen. Lokhu kushintsha kulawulwa ukuthi kwenzeke ngesigqi esilawulwayo, ngokuvamile ngokulandelana kwemizuzwana, futhi ngaleyo ndlela umphumela uhlala uzinzile. Lokhu kungaboniswa njengezisebenzi ezimbili ezineshejuli yokushintsha. Omunye usekukhiqizweni kanti omunye uphumule, elungiselela umzuliswano olandelayo. Bayashintshana, ngakho akukho ukuyeka ekukhiqizweni.

Isingeniso Semisebenzi Yengxenye Ngayinye Kuhlelo Lwe-PSA

Uhlelo lwe-nitrogen lwe-PSA lufana neketanga, elinesixhumanisi ngasinye esinomsebenzi walo othize. Ukwehluleka kwengxenye eyodwa ukufeza umsebenzi wayo kusho ukuthi yonke inqubo ayizinzile. Ukwazi lezi zingxenye kukuvumela ukuthi uqonde kalula ukukhiqizwa kwe-nitrogen uma kudingeka. Ngokuvamile, kuqala ngokungasebenzi kahle kwe-compressor yomoya. Le yunithi idonsa umoya ojwayelekile bese iwucindezela ngengcindezi efanele. Uma lesi sinyathelo singathathwa, umoya uzoba buthaka kakhulu ukuthi ungasetshenziswa enqubweni yokuhlukanisa. Umoya ocindezelwe usashisa futhi ungaba ngamanzi noma uthuli. Yilapho isigaba sokwelashwa komoya singena khona. Izihlungi nezomisi zihlanza umoya ngaphambi kokuba ungeniswe ohlelweni oluyinhloko. Le nqubo isiza ukugcina isihlungo se-carbon molecular futhi silondoloze ukuzinza kokusebenza ngokuhamba kwesikhathi ngenxa yokususwa kothuli nomhwamuko wamanzi. Okulandelayo yithangi le-Air Receiver. Lokhu kufana ne-buffer. Kuqeda noma yikuphi ukuxokozela ekugelezeni komoya kuyunithi ye-PSA, kuqinisekisa ukugeleza komoya ocindezelwe njalo. Lokhu kusiza ekugcineni ingcindezi ngesikhathi sokusebenza. Okulandelayo, ingxenye eyinhloko yesistimu yimibhoshongo emibili yokumunca elayishwe ngezisefo zama-molecule e-carbon. Imibhoshongo emibili yokumunca equkethe izisefo zama-molecule e-carbon bese kuba yinhliziyo yesistimu. Le mibhoshongo iyashintshana ekuhlukaniseni umoya-mpilo ne-nitrogen. Umbhoshongo owodwa ukhiqiza i-nitrogen kanti omunye uyahlanzwa futhi usethwa kabusha. Lokhu kushintsha kuqinisekisa ukuthi ukukhiqizwa akuphazamiseki.

Izici Eziyinhloko Ezithinta Ukuhlanzeka Kwe-nitrogen kanye Nezinga Lokugeleza

Inani le-nitrogen emsulwa kanye nesivinini sokugeleza kwayo iphuma ohlelweni lwe-PSA akukaguquki. Kuzohluka ngokuya ngesimo kanye nokusetshenziswa kohlelo. Kunezici ezimbalwa ezibalulekile ezidlala indima enkulu ekuhlanzekeni kwegesi ye-N2 nokuthi ingakanani igesi engakhiqizwa ngenani elithile. Esinye sezici ezibaluleke kakhulu ukucindezela komoya. Imishini ye-PSA nitrogen generator uhlelo kumele lube nenani elifanele lokucindezela ukuqinisekisa ukuthi igesi yomoya-mpilo iya esisefweni se-carbon molecular. Ukucindezela okunganele akusizi ekuhlukaniseni umoya-mpilo futhi kunciphisa nobumsulwa be-nitrogen. Uma kuphezulu kakhulu, kungenzeka ukuthi uhlelo luzolahlekelwa amandla ngaphandle kokukhiqiza okuningi okukhiphayo. Ukusetha okuvame kakhulu ukushintshashintsha ingcindezi ukuze uthole ibhalansi efanele. Okunye ukuthi umoya uzohamba ngokushesha kangakanani. Inani elikhulu kakhulu legesi lifakwa ngesikhathi esisodwa, okunganele ukuvumela isisefo ukuthi sisebenze kahle. Lokhu kungabangela ukuthi ikhwalithi ye-nitrogen yehle. Kodwa ezimweni zokugeleza komoya okuphansi, ukuntuleka komkhiqizo kanye nokungasebenzi kahle kungenzeka. Noma yikuphi ukuhlanzeka kanye nebhalansi yesivinini.
